摘要： A rolling mill gauge control system and method are disclosed for controlling the delivery thickness or gauge of a strip workpiece leaving one or more roll stands of a tandem rolling mill. The initial roll opening setting and the initial speed setting for each roll stand are typically provided by an operator or a schedule calculation computer system prior to the passage of the work strip through the roll stand. Assuming these initial speed settings are correct, the known mass flow operational condition of the work strip in relation to the last stand target delivery gauge is used to establish the initial desired mass flow delivery gauge from each controlled roll stand of the rolling mill in relation to the desired delivery gauge from the last roll stand. Then as the work strip passes through each successive roll stand, and before the work strip reaches the X-ray gauge measurement device following the last roll stand, the roll force determined actual delivery gauge from each roll stand is compared with the initial desired mass flow delivery gauge to determine a work strip gauge error leaving the latter roll stand, which gauge error is utilized for determining a desired correction in the roll opening setting for that roll stand before the work strip reaches the X-ray gauge device.
