Abstract

Gage control method and system for tandem rolling mills of the type wherein final output gage is controlled by comparing actual output gage with desired output gage to develop an error signal for controlling the speed of the last stand and, hence, tension in the strip material being rolled between the last two stands. The invention is characterized in that the roll force exerted on the strip by the last stand is maintained constant for all variations in last stand speed, thereby enabling a greater range of strip gage change via the last stand in the tandem mill.
