A temper mill is a finishing facility that processes steel in the form of sheet and plate in order to give it added strength and uniform flatness to the surface. The metal forming method at a temper mill involves rolling the sheets of steel through what is known as a cold reducing process or temper pass.
Mills - 4-HI. Cold rolling is accomplished by processing steel strip through a series of Tandem Rolling Mill "Stands.". Each stand has vertically assembled rolls that are powered by large motors to transmit high compressive pressures into the material. Hot-rolled, pickled coils are fed into the cold rolling mill from an uncoiler and ...

It consists of a two-stand UCM and is designed to perform double-cold reduction as well as one-stand temper rolling. In the DCR process, the annealed strip, after reduction in a tandem cold mill, is reduce rolled on the No. 1 stand and temper rolled on the No. 2 stand. This process imparts the strip with its prescribed mechanical strength.

This 14″ mill can hold 25% of standard hot-rolled tolerances in a single pass. Our gauge range is .060 to .240 and widths 2.500″ to 12.000″. The cold rolled strip steel that runs on this mill is inspected at rolling.
Nowadays the industry is facing one of the basic problems that is failure and breakage of rolls in rolling mills. Roll breakage and cracks on its surface occurs due to overdraft or due to multiple passes which increases stress on a particular area. The forces and work load on the portion where the rolls comes in contact with the rolling surface can be found out.
