The cold rolling mill is usually fitted with thickness gauges that check the steel as it comes out of the rollers. Reversing mills are designed so that the steel can be reversed and pushed back through the rollers which are brought closer together each time until the desired thickness is achieved. Multi-stand mills have three to six pairs of ...

The mathematical model of the cold thin-sheet rolling process on a reversing mill equipped with a four-high stand, a coiler, and a decoiler was constructed based on the data of [6, 7]. Using the equation of the power balance during the reversing rolling, the relation for the specific power consumption ({{W}_{Sigma }}) was written as [ 8, 9 ]

Reversing mills are generally used for smaller scale production of the cold rolled products. 2. COLD ROLLING MILL: The function of rolling mill is to reduce ingoing strip at room temperature by 50 to 90%. The reduction of strip thickness is caused by compressive stresses in contact region between work roll surface and strip.
