A temper mill is a steel sheet or steel plate processing line composed of a horizontal pass cold rolling mill stand, entry and exit conveyor tables and upstream and downstream equipment depending on the design and nature of the processing system.
The primary purpose of a temper mill is to improve the surface finish on steel products.
Also included in a typical temper mill installation are pinch rolls, a leveler (sometimes two levelers), a shear for cutting the finished product to pre-determined lengths, a stacker for accumulating cut lengths of product Sometimes a temper mill installation includes a re-coil line where the finished product is a coil instead of bundles of cut lengths of product.
It will include electric powered drive motors and speed reduction gearing suited to the process desired.
The process goal is physical property enhancement through cold forming of the steel product in the bite of the work rolls.
