Abstract
PURPOSE:To control the thickness of a steel plate in longitudinal direction at high accuracy by correcting shifting time between a rolling mill and a plate thickness measuring device and fedding back a control signal in feedback control of the plate thickness of a rolled steel plate in a rolling mill. CONSTITUTION:The plate thickness in longitudinal direction of a strip SP that came out from the final rolling stand is measured by a thickness meter X and the data are inputted to an adder A together with the output of a shifting time correcting device Ev. The two outputs are added and inputted to a PID arithmetic device G. At the same time, detected value of roll speed obtained from a roll speed detector V is multiplied by a coefficient proportional to roll speed for output of integration out of output from PID arithmetic device, and a coefficient inversely proportional to roll speed for output of differentiation. These are fed back as operation signals of the stand ST, and the rolling speed of the stand ST is controlled to make longitudinal plate thickness uniform.
