Abstract

PURPOSE: To reduce rolling loads and hold the plate thickness of products always even by rolling the plate while changing the peripheral speeds of two work rolls in proportion to the driving torque change quantity of work-roll-driving motors at the increasing or decreasing of the inlet side plate thickness at the time of performing RD rolling.
CONSTITUTION: At the time of rooling a steel plate by an RD rolling method, the rolling is accomplished while the peripheral speed ratios of the upper work roll 1 on the high speed side and the lower work roll 2 on the low speeed side are being increased or decreased in proportion to the change quantity of the driving torque of the work-roll-driving motors 3, 4 at the increasing or decreasing of the inlet side plate thickness of strip S to be rolled. The considerable decrease in the rolling load by the RD method may be achieved and the exit side plate thickness h1 may be maintained at always a fixed value despite any change in the inlet side plate thickness h0.
