ENERGY STORAGE COMPONENT FORGINGS Energy Storage - Forging The Future Are you at the forefront of electric energy storage development? As this industry is poised to become an essential element of the electricity infrastructure of the future, we are here to help. Acting as an extension of your team, our metallurgists are well versed in material development, our forge engineers have decades of experience making the impossible possible, and our sales team is your advocate for getting parts on time, as promised. Whether you're working on one-off projects for energy storage R&D - including material design - or looking to get ahead by scheduling out your repeat components, you can rely on Scot Forge. RENEWABLE ENERGY FORGE CONSULTATION & CUSTOM ENGINEERING We want to be more than just a manufacturer meeting your needs. We want to be a partner in getting our world to net-zero emissions by helping you discover opportunities and overcome challenges that energy storage presents, which according to Sandia National Laboratories, include: Offsetting the need for additional peaking generation capacity and reducing equipment wear, fuel use and air emissions. Enabling effective, optimal integration of intermittent renewables and possibly baseload renewables. Providing secondary services, helping distribute the electrical follow and supply reserve capacity, which will probably become a crucial element of the Smart Grid, facilitating 'demand response' resources. Giving utility planners and engineers flexible, reliable, and possibly less-risky alternatives to investments in conventional energy. Addressing growing electric service power quality and electric service reliability challenges, possibly by enabling utilities to provide differentiated electric service with higher quality and/or reliability. Forging for Energy Storage Including: Pumped Hydroelectric Energy Storage. A popular form of energy storage, pumped-storage hydroelectricity is typically designed to store excess power from the grid. Using the excess electricity to pump water up to a reservoir can be stored then released when demand rises. Similar to hydropower, once released, the water flows down through a turbine to generate electricity. The turbine/generator is similar to typical hydroelectric power plants that do not incorporate storage. Compressed Air Energy Storage. Compressed air energy storage (CAES) involves using excess energy to compress air at up to 1,000 pounds per square inch, creating a high-pressure system in a series of large underground chambers. This energy storage method is coupled with wind energy. When the wind speeds slow or power demand surges, the pressurized air energy, typically mixed with a bit of natural gas, is released to spin turbines turning generators to create electricity. Flywheel Energy Storage. Flywheel electric energy storage systems include a shaft connected to a cylinder that spins rapidly within a vacuum-sealed enclosure attaining rotational speeds up to 60,000 revolutions per minute. Some flywheels use magnetic bearings to levitate the cylinder, thus limiting friction-related losses and wear. Excess electricity is used to accelerate a flywheel (a type of rotor) through which kinetic rotational energy is stored. When the electricity is needed, the stored energy is converted via slowing the flywheel's rotational speed through a shaft that turns a generator. Thermal Energy Storage. Electricity can be used to produce thermal energy. According to the International Renewable Energy Agency, "coupling heating systems with thermal and seasonal storage offers important flexibility in demand in regions where winters are particularly harsh. For example, the Drake Landing Solar Community in Canada uses a long-term thermal energy storage system to store heat from solar collectors during summer for space heating during winter. In coupling the power and thermal sector, Siemens-Gamesa is testing a thermal energy storage system that uses wind power to produce heat stored in over 1,000 tons of rock. This system provides a thermal storage capacity of 130 megawatt-hours of electric energy at rated charging temperatures of 750°C. IRENA estimates that around 234-gigawatt hours of thermal energy storage are present, a crucial enabler of reliable, secure and flexible energy systems." Superconducting Magnetic Energy Storage. A superconducting magnetic energy storage system (SMES ) stores electricity as a magnetic field in an environment cooled below the temperature needed for superconductivity. As long as this temperature is maintained, energy can be stored indefinitely because the current will not degrade. Additional SMES components include power conditioning equipment and a cryogenically cooled refrigeration system. Methane. Researchers have developed a way to take the products of biomass gasification to produce methane, which is then be burned to power turbines. Methane essentially serves as an energy storage medium and can be stored or easily piped/shipped using the existing natural gas infrastructure.

Manufacturing is a great field for a variety of reasons. Learn more about what you can earn and save by choosing a career in manufacturing! Why Manufacturing? Thinking About A Career In Manufacturing? Manufacturers represent the backbone of the innovation economy and do most of the nation's Research and Development. They employ many skilled workers, from engineers and programmers to technicians and logistics managers. They are a major source of employment. FACTS ABOUT MANUFACTURING WHY CHOOSE MANUFACTURING Useful Education Manufacturing-Focused Skills Math for technicians Safety Hand tools Electrical systems Blueprint reading Power tools Lean manufacturing Measurement and quality control Pneumatics Hydraulics Sensor technology Robotics Material handling Computer integrated manufacturing Millions of Future Jobs According to a study by Deloitte and the Manufacturing Institute, over the next decade, nearly 3.5 million manufacturing jobs will likely be needed and two million are expected to go unfilled due to the gap between the talent manufacturers’ need to keep growing their businesses and the talent they can actually find. A Better, Safer Work Environment A large cause of the gap is a lack of knowledge and understanding about what a career in manufacturing actually looks like. The stereotype over the years has been that work is monotonous and factories are dark, dirty and dangerous places. The truth is that manufacturing plants are very technologically advanced places and a lot of the work that is manufactured is highly mechanized. Lucrative Careers, Not Just Jobs Unlike many other industries that only provide jobs, manufacturing provides careers. Educators, administrators and staff need to realize not all students are bound for college and a four-year degree. Instead, they need to understand alternatives where people can earn a good living wage without straddling themselves with debt. Many intelligent individuals struggle with traditional high school learning and test-taking. These students are more visual learners and tend to be mechanically inclined. Careers such as a machinist, a tool and die maker or a welder are critical jobs that can be very lucrative due to their high demand, and students have the ability to earn a great wage and start their career right out of high school. Avoid Crippling Debt Research conducted by the Idaho Department of Labor found that the average bachelor’s degree in the United States costs $127,000! Additionally, nearly 70 percent of students take out loans to help pay for school. According to the National Student Loan Data System (NSLDS), the average 2016 college graduate has over $37,000 in student loan debt and an average monthly student loan repayment of over $350. Manufacturing can provide students with a bright future filled with opportunity and success. It can enhance a student’s potential to specialize in lucrative career fields, provide a clean and technical work environment, help advance the U.S. economy and offer paths to additional industry credentials. Working with high-technology equipment, being a part of an important industry and entering into a field with opportunity instead of debt are a few benefits of choosing a career in manufacturing. Emphasis On Career Readiness Educators shoulder the responsibility to prepare college-bound students to be “college-ready;” however, they also need to emphasize “career ready” equally. Schools need to reinforce and be comfortable with the statement: “It’s OK to not get a traditional 4-year degree.” After graduation, students need to learn about their options; schools should be driven to provide students with the resources necessary to develop them into productive members of the workforce and society. Manufacturing Careers In High Demand Careers in manufacturing are expected to increase at a rate of 10 percent over the next seven years according to the US Bureau of Labor Statistics. Those careers range from assembly and fabrication to computer programming, sales and more. Some manufacturing jobs require certifications and some require degrees, and all are equally important. Whether an individual wants a hands-on job in manufacturing or is interested in behind-the-scenes logistics, there are vast opportunities within the manufacturing sectors —specific industry knowledge can help them pursue many possibilities. Many of the skills learned are applicable to other jobs in the broad manufacturing field. This can make it easier to find jobs and provides more opportunities for career advancement. Earn While You Learn Manufacturing, a highly technical trade, provides higher-than-average wages and benefits for employees. At Scot Forge, we offer our employees up to $5,000 a year to cover all costs of pre-approved undergraduate, graduate and postgraduate degree level programs if they wish to pursue a higher-education degree. We also pay for any pre-approved courses and non-degree certificate programs in any field related to an employee’s career. As a continuously improving company, we encourage all employees to improve their skills on a regular basis. So, we offer enriching employment opportunities through a variety of formal internship and student learner programs, registered apprenticeships and job shadowing. Additionally, we bring in professors from local colleges to make learning more convenient.

At the heart of the operation is our custom-designed, computer-controlled GFM single-stand planishing mill. Through a series of reversing passes, the planishing mill rolls the bar to a smooth surface in less than five minutes. While still hot, the bar moves down the GFM mill to the Braun abrasive saw station for trimming. A 16’ round can be cut in less than half a minute. To complete the process, the bar is end-stamped for traceability by an automated programmable marking system. The bar is then slowly rotated down an automatic uniform cooling bed to maintain straightness. Since the bars can be produced so efficiently in the planishing mill, delivery times are reduced. Unlike traditional hot-rolled bars, which can only be manufactured in large runs, forged Tartan Round Bars can be purchased in quantities as small as the product of one ingot.

Finish rolling (or planishing) begins as the forged bar goes through one of the four hyperbolic grooves of the custom-engineered GFM bar mill. The desired final dimension is reached after a series of bar rotations and reversing passes through the grooves, taking less than 3 minutes to complete.

Bars are slowly rotated down an automatic uniform cooling bed to maintain straightness. A 50,000 gallon quench tank and nine tip up furnaces have been custom-designed to efficiently handle any bar requirement. Process options include normalize, anneal, solution anneal, quench and temper, and stress relieve. A custom-built Hetran bar peeler provides fast, centerless machining to extremely smooth surfaces. This peeling process takes less than one-fourth the time of conventional turning operations.

Forging Cost Reductions Improve Your Parts Forging can often create economic advantages over other metalworking methods that save time and materials, as well as improve production efficiencies. Scot Forge employee-owners collaborate with you to discover the most viable solutions for your project. Our highly trained account managers, forge engineers, process engineers and metallurgists add decades of knowledge and experience to your team. CONVERTING HISTORIC DESIGN TO A FORGING QUALITY ASSURANCE CLICK THE TOPICS BELOW AND DISCOVER: Material Optimization Forging can measurably reduce material costs since it requires less starting stock to produce many part shapes and can achieve near-net shapes, saving on scrap costs. Part Design & Component Reduction By minimizing the number of components in a fabricated part and enhancing design, Scot Forge can produce parts with increased quality while reducing overall cost and production time. PRODUCTION EFFICIENCIES Scot Forge has many different sizes of starting ingots and billets on hand, providing a wide variety of ready-to-forge inventoried grades. Using the forging process, the same part can be produced from many different sizes of starting ingots or billets, allowing for a wider variety of inventoried grades. This flexibility means that forged parts of virtually any grade can be manufactured more quickly and economically. Machining Economies Forging also can yield advantages in machining, lead time and tool life. Savings come from forging to a closer-to-finish, or near-net, size than what is capable by alternative metal sources such as torch cutting plate or boring bar. Therefore, less machining is needed to finish the part, with the added benefits of shorter lead times and reduced wear and tear on your equipment. REDUCED REJECTION RATES Often discovering a defect in a cast part doesn’t happen until a part has been on a machine for hours, which can be a headache. But, when this happens to multiple parts it can be a nightmare. It takes time and money to replace parts, puts hours on the machine and increases labor costs, not to mention the lost opportunity cost. Because forging has a 3:1 minimum reduction, porosity and piping are eliminated yielding improved structural integrity. Coupled with a weld-free design, forging can dramatically reduce part rejection. Real Examples of Forging Reducing Cost MATERIAL OPTIMIZATION For example, torch cutting a ring from plate (A), all corner stock and the full center slug are lost, as a result you pay for the excess material. With a forging (B), the part is shaped to a near-net size with minimal waste and optimized use of starting stock. Hubs Torch Cut Parts Hollows Rings Spindles Open die forging and torch cutting allows for a surprisingly large range of sizes and shapes Torch cutting to near net shape saves on machining times without incurring custom die costs. Problem Castings are not always economical and can extend deliveries. Machining from a large block or plate can result in excessive machine times. The need to manufacture dies for specifically shaped castings often result in extended deliveries Castings produce enlarged grain structure, which lowers mechanical properties Excessive costs for small quantity casting runs are incurred due to expensive molds and set-up times When forging to near net is not an option, machining excessive amounts of material from plate is inefficient SOLUTIOn Our forging and torch cutting capabilities allow for intricate jobs to be manufactured economically and with shortened lead times. Our forgings can often be manufactured without the need for custom dies, and our CNC torches can be individually programmed for specialty shapes Forgings produce improved integrity in the finished part for better product reliability Material and labor cost savings through the combination of custom forging near net finished sized with subsequent contour torch cutting. Compared to traditional machining, torch cutting is more efficient, which results in quick turnaround Complete torch cutting capability including pre- and post-heating processes to aid cutting accuracy and relieving stresses for over one hundred different grades of carbon and alloy steels Our forging process allows for high-quality hollows Unlike rolled and welled plate, our hollows are forged seamlessly and utilize in-house tooling to create near net and low cost options. Problem Centrifugal castings are not always economical and can extend deliveries. Heavy wall centrifugal castings often fail to meet critical I.D. surface requirements and require welding and re-machining. The need to manufacture dies for specially shaped centrifugals often results in extended deliveries. Excessive costs for small-quantity runs are incurred due to expensive molds and setup times. Centrifugal castings produce enlarged grain structure, which lowers mechanical properties. SOLUTIOn Custom hollow forgings offer consistently high quality, often at lower costs and with quicker turnaround times. Hollow forgings are uniformly forged with guaranteed soundness regardless of section size. Our extensive in-house tooling enables us to forge a large variety of hollows without added costs or extended lead times. Setup time is nonexistent for hollow forgings, keeping costs and lead time to a minimum whether the quantity is one or one hundred. Our forging process produces a seamless cross section and continuous grain flow which yields the optimum combination of fatigue strength and toughness. The hollow forging process offers a greater variety of O.D. as well as I.D. configurations thus reducing machining time and cost. Using our custom engineered, in-house tooling, we are able to provide thick walled hollows with multiple steps on both the O.D. and I.D. Forging Process Rejection - 0% Continuous grain flow shown on a stepped O.D. and I.D. in the as-forged condition. Centrifugal Casting Process Rejection - 10% The same part shown with columnar grain flow in the as-cast condition. Note extra stock on the O.D. and I.D. required for centrifugal casting vs. forging Forged rings are able to be individually customized for near net shape In material cost, versatility and quality, forged ring solutions deliver superior outcomes compared to flame cutting rings from plate. Problem Flame cutting a ring from plate is not always viable when meeting material requirements, or economical. Material costs are increased due to removal of excess corner stock and center slug. As desired thickness of the ring increases, availability of plate sizes and grades drastically decreases. Uni-directional grain flow of plate increases susceptibility of ring to fatigue failure. SOLUTIOn A custom-forged ring allows greater versatility and improved quality while reducing material cost. The forging process moves and shapes material to ordered ring size with minimal material waste. Required ring thickness has no effect on the virtually limitless combinations of sizes and grades available. Contoured grain flow within forged ring yields optimum combination of strength, toughness and fatigue resistance. The porosity and laminations sometimes encountered in plate is eliminated with a custom-forged ring. Our forged stepped spindles allow endless flexibility in size and variation Reduce material waste, machine times, and freight costs with forged stepdown solutions instead of machining solid bars. Problem Machining a solid bar to form a step-down causes wasteful use of material, labor and time. When machining the step-down, all excess material, as shown here, is lost. Machining time, tool life and freight costs are excessive. Grain flow within the bar is exposed when machined, thus making the material more susceptible to fatigue failure. SOLUTIOn Custom-forging the bar to form a step-down lowers the cost for a value-added part. Forging requires less starting material than a straight round bar machined to shape. Less machining saves money, time and tool life while producing a closer-to-finish shape. Freight and handling costs are lowered because a forged stepdown weighs less than a bar. Contoured grain flow within a forged stepdown yields greater impact and directional strength. Forging allows custom sizes and material savings Our extensive inventory of in-house tooling allows for many custom sizes with quick turnaround for low quantity jobs. Also, for unique applications, we can design specialized tooling. Problem When hub shapes are achieved through machining solid bar stock or flame cutting plate, waste is an inescapable part of the process. When machining a shape from solid bar or flame cutting plate, all excess material—material paid for—is lost. Machining or flame cutting means costly machine time, lowered tool life and increased freight costs for material. Most importantly, the uni-directional grain flow of both bar and plate increases the likelihood of failure due to fatigue. SOLUTIOn Custom forging of hub shapes improves quality, lowers material costs, and offers maximum flexibility. Forgings save on both material and freight costs because it requires less starting stock. Our forgings are produced to a nearer net shape, reducing machine time and labor costs. The optimum combination of strength, toughness and fatigue resistance in the hub is achieved by the continuous grain flow which comes through forging. When machining a shape from a solid bar or flame cutting a plate, all byproduct is wasted at the expense of the customer. Part Design & Component Reduction PART DESIGN Rolled and welded or cut rings from plate are susceptible to fatigue, and carry excess material and processing costs. In the cases below, these common problems were solved by switching to the forging process. Achieving Structural Integrity Optimizing Toughness Enabling Size Versatility Product/application Corrosion-resistant profiled ring, 200" O.D. and 42" face Material Nickel Aluminum Bronze Previous processing problems Three different metalworking processes were attempted to make one ring: a forging, a casting, and a rolled and welded plate. The cast ring failed sonic requirements and had inclusion problems which required excessive machining and weld repair. Extensive welding on the fabricated ring reduced part integrity, jeopardized corrosion resistance and caused distortion of the ring's shape. Forging as the solution Today a forged, profiled seamless rolled ring produces unsurpassed structural integrity. Overall strength is increased through forging's directional grain flow. With the absence of welding, part integrity, corrosion resistance and shape are maintained. Product/application Large gear Material Alloy Steel PREVIOUS PROCESSING PROBLEMS The part was previously produced as a cast ring, with high maintenance and repair costs. The absence of grain flow and directional strength caused part integrity problems. Gears were breaking in the field due to fatigue failure, shortening the service life of the product. Forging as the solution Today the part is made as a contoured forged ring Forging yields improved mechanical properties, reducing the risk of part fatigue and breakage. The continuous grain flow, provided by the forging process, optimizes part integrity and impact toughness. Product/application Bearing application component Material Alloy Steel Ring Size 95-7/8" O.D. X 40-5/8" I.D. X 8-5/8" Thick Previous processing problems The past production process involved torch cutting a heavy wall ring from plate. Excess waste was substantial, since all corner stock and the full center slug of the plate were lost. Desired plate sizes and grades were sometimes difficult to obtain due to ring thickness. Parts were rejected due to inclusions found on the polished surface of the plate. Forging as the solution Today a custom-forged rolled ring allows greater size versatility while oftentimes reducing waste and material costs. Porosity, laminations and inclusions sometimes found in plate are eliminated through the refined grain flow inherent in a forging. COMPONENT REDUCTION When Scot Forge evaluates prints or specifications, we look for ways to eliminate unnecessary steps and expenses while making a superior part. For example we could forge a single component instead of welding multiple pieces together. Consistent Quality Eliminating Steps Reducing Rework Product/application Heat exchanger body Material 90/10 Copper Nickel Previous processing problems Part originally consisted of three components: one rolled and welded plate and two forged rings welded to the ends. The two different metalworking processes made the welding difficult with inconsistent results. Inclusions were present in the plate, requiring extensive weld repair and reinspection. Weld areas required expensive X-ray testing. Forging as the solution Today the part is made as a single forged piece with integral flanges. Consistent quality is assured throughout the part, eliminating the instances of inclusions, making welding unnecessary. Without welding, X-ray testing is not needed. Product/application Cylinder rod for bucket Material Low-Alloy Steel Previous processing problems Previously the part was made from a cast head welded to a hot rolled bar. Casting proved too weak for the application, resulting in shortened product life. The need for welding lengthened process times. In the field, excessive loads on the cast head caused part failures and required subsequent repairs. Forging as the solution Today the part is made as a one-piece forging. Forging allowed the head and shaft to be produced as one part. The strength and structural integrity of the forged material met demanding application requirements. The elimination of welding has shortened part production process time. The forged head is able to withstand excessive loads without failure. Product/application Mixer shaft Material Stainless Steel Previous processing problems The former part was a rolled bar welded to a forged blank. Heating required during the welding process changed the hardness and tensile properties in the weld zone, making it necessary to re-heat treat the part. Cracking was occurring in the weld layer, rework was needed, and there were many failures in the field. Forging as the solution Today the part is made as a one-piece forging. No welding or heating is required, improving properties and eliminating non-value-added steps. Part strength has improved due to one-piece construction and continuous grain flow, resulting in less rework, fewer rejections and increased part life. Machining Economies Below are some examples of how forged hollow products have served as a customized solution for many of Scot Forge's customers—providing a stronger, high-quality product while eliminating excess time, cost and material waste. As you can see less machining is needed to finish the part, with the added benefits of shorter lead times and reduced wear and tear on your equipment. Cutting Waste Reducing Machining Improving Integrity Product/application Paper rollers Material Carbon Steel PREVIOUS PROCESSING PROBLEMS Off-the-shelf tubing was previously used to form this part. Limited available sizes often required excess machining. Frequent inclusions resulted in poor surface quality and low part strength, causing internal rework and high part rejections Forging as the solution Custom-tailored hollow forging has eliminated the need for excessive machining. The combination of using cleaner material and the forging process prevents inclusions, raising part strength and quality. This has solved former internal processing problems. Product/application Paper rollers Material Carbon Steel Previous processing problems Off-the-shelf tubing was previously used to form this part. Limited available sizes often required excess machining. Frequent inclusions resulted in poor surface quality and low part strength, causing internal rework and high part rejections. Forging as the solution Custom-tailored hollow forging has eliminated the need for excessive machining. The combination of using cleaner material and the forging process prevents inclusions, raising part strength and quality. This has solved former internal processing problems. Product/application Piston rod Material Low-Alloy Steel Previous processing problems Formerly, a solid steel bar was bored, machined, heat treated, and then finish machined with a tapered inside diameter. Bar size limitations, and the need to bore out the I.D. resulted in extensive material waste. Excessive machining caused high costs and shortened tool life. Since the I.D. was not tapered prior to heat treating, core hardness could not be achieved in that area. Forging as the solution Today, custom hollow forgings produce a near net shape, reducing material by 23%. Less machining saves time, cost and tool life. Tapered I.D. is achieved during the forging process, which allows core hardness requirements to be met during heat treating. Product/application Recoil cylinder Material Low-Alloy Steel Previous processing problems A centrifugal casting with a straight I.D. and single-step O.D. was formerly used. Failure to meet critical I.D. surface requirements often caused extensive welding and machining repair. High rejection rates were experienced due to poor casting integrity. Excessive reworking costs and failure to meet critical production deadlines were causing major problems. Forging as the solution Today, a hollow-stepped forging is produced with an integral-stepped I.D., delivering higher value with a stronger, near-net shape. Hollow forging the part with a double O.D. and I.D. produced a stronger, near-net shape at less cost. Forging produces a continuous grain flow, yielding the optimum combination of fatigue strength and toughness. The need for weld and machine repair is no longer required; the integrity of the forging eliminates part rejection.
