ABSTRACT:
A plate-like rolled material fed from a continuous casting equipment is rolled by a vertical mill for width control. A pair of horizontal mills are disposed one on each of the entry side and the delivery side of the vertical mill. Both the horizontal mills are controlled in their speeds to impart a predetermined tensile force to the rolled material without effecting thickness control of the rolled material. The roll speed of the horizontal mill disposed on the delivery side is controlled to be higher than that of the horizontal mill disposed on the entry side. This enables preventing of failure in the shape of the rolled material.
