Abstract

Control system for tandem strip rolling mill streets comprising the adjustment of roll speed and roll gaps of strip with leading and trailing sections, the end of successive strips being joined, comprises a device for resetting the roll gaps and speeds of the various mills and another device for following through the joint areas to ensure that each mill is adjusted for the characteristics of the new strip as it enters the requisite roll gap. Also provided are additional programming devices for correlating the data of successive strips to ensure that no building up or excessive tension occurs between successive mill stands resulting in damage to the strip as the result of the changeover to successive strips. The system permits the completely automatic operation of strip mills and greatly reduces reject strip.
