 Tartan
Bars® Process
 |
1) Car bottom forge
furnace with hot ingots
Carbon, alloy, stainless,
copper-based and other ferrous and non-ferrous high
quality starting material is heated to forging temperature
in car bottom furnaces. Overall heating capacity
exceeds 3,000,000 pounds.
|
|
2) Press
forging
Hydraulic
open die presses (2,000 & 1,250 ton) forge
the heated material to both consolidate the center
for soundness and size the material in preparation
for bar mill processing. |
 |
 |
3) Rolling to finish on the bar mill
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. |
4) Hot abrasive
cut-off saw
While still hot, bars are cut to size by a Braun
abrasive saw. A 16" round can be cut in less than half
a minute. |
 |
 |
5) Automated end stamping
Bars are end stamped
for traceability by an automated programmable marking
system. |
6) Slow cooling bed
Bars are slowly rotated down an automatic uniform
cooling bed to maintain straightness. |
|
|
7) Thermal treatment
(optional)
A 50,000 gallon quench tank and 9 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.
|
8) Bar peeler
(optional)
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. |
 |
 |
9 ) Automated Ultrasonic Testing (optional)
Ultrasonic inspection can be performed on TARTAN BARSŪ to assure a sound, quality
product.
