Abstract

PURPOSE:To control the plate thickness of outlet side of downstream stand constant by changing tension between two stands adjusting peripheral speed of rolls of upper stream stand. CONSTITUTION:A plate thickness detector detects plate thickness of outlet side of an upper stream stand out of two stands and determines plate thickness deviation DELTAhi. Time required until the material having plate thickness deviation DELTAhi reaches a downstream stand is determined from material speed detected by a material speed detector, and after lapse of determined time, a delay circuit outputs the plate thickness deviation DELTAhi as inlet side plate thickness deviation DELTAHi+1. Peripheral speed correction DELTAWi for rolls of upper stream stand is determined from inlet side plate thickness deviation DELTAHi+1 of downstream stand and roll peripheral speed reference value DELTAWi of upper stream stand by an arithmetic device using the expression. Tension between two stands is changed by adjusting roll peripheral speed DELTAWi of upper stream stand, and the plate thickness of outlet side of downstream stand is controlled to a constant value.
