Abstract

PURPOSE:To control the plate thickness of a rolled stock correctly by controlling the outlet side plate thickness of a stand that has no thickness gauge excellent in response property, applying a rule that the volume speed of a rolled stock does not change between the inlet side and outlet side of a stand in rolling a steel plate by a tandem rolling mill. CONSTITUTION:In a tandem rolling mill of five stands, outlet side plate thickness deviation of the first stand which is up-stream side of the second stand, is inputted to a plate shifting delay arithmetic device 45. It is then inputted to an arithmetic device 46 as the second stand inlet side plate thickness deviation giving time corresponding to shifting delay from the second stand. Using a rule that there is no change in material volume speed between inlet side and outlet side of the second stand, outlet side plate thickness deviation of the second stand is calculated. Outlet side plate thickness of the second stand is controlled to target thickness by correcting the roll peripheral speed of upstream side stand by using a speed correcting device 16 to make the value to zero. The same control is performed in each stand as well.
