Abstract

PURPOSE: To make possible the great rolling reduction as compared with the uni- speed rolling mill, and to improve the productivity, in the rolling mill possessing rolls rotating at different speeds, by controlling the speed ratio of reducing rolls according to the signal produced from the shape detector installed on the delivery side.
CONSTITUTION: In the single stand ST whose reducing rolls 2a, 2b, are rotating at different speeds, the shape of the rolled material 1 on the delivery side is detected by the sensor D; the output of the sensor D is inputted to the operator C; the controllers SC1, SC2, for driving motors Ma, Mb, of upper and lower rolls 2a, 2b, are controlled respectively by the speed reference signals V1, V2, produced from the operator C; hereby, the shape of the rolled material 1 is controlled. This rolling mill can give a greater rolling reduction as compared with the rolling mill whose upper and lower rolls are rotating at identical speed. In case of the multistand mill, it is sufficient to control the final stand by this method. The rolling reduction at the final rolling stand can be increased than the case of conventional method, so that the number of rolling passes can be reduced.
