A rolling mill for rolling metal strip moving in a horizontal rolling direction, has work rolls which engage the strip and are supported vertically by backup rolls through which drive is applied. The work rolls are supported in the horizontal rolling direction by support rollers contacting them at locations confined to intermediate regions between the work regions and bearings.

Hot Strip Mill and Cold Rolling Mill

There are two types of rolling. With hot rolling, heated metal goes through a rolling machine where it is worked into a sheet or bar. With cold rolling, sheet steel is made thinner at normal temperatures, and its surface is made smooth and uniform. Tsubaki products are used in both hot and cold rolling.

Strip Thickness Control of Cold Rolling Mill with Roll

Nov 12, 2013In rolling mill, the accuracy and quality of the strip exit thickness are very important factors. To realize high accuracy in the strip exit thickness, the Automatic Gauge Control (AGC) system is used. Because of roll eccentricity in backup rolls, the exit thickness deviates periodically.

Forward slip is an important parameter often used in rolling-speed control models for tandem hot strip rolling mills. In a hot strip mill, on-line measurement of strip speed is inherently very difficult. Therefore, for the set-up of the finishing mill, a forward slip model is used to calculate the strip speed from roll circumferential velocity at each mill stand. Due to its complexity, most
