Abstract: A roll eccentricity control system for rolling apparatus in which a period of each cycle corresponding to one revolution of the roll is divided into a plurality of sections, a deviation in thickness of the rolled material in each section is sampled during the rolling operation, the sampled deviations in the respective sections for at least one period are averaged to determine a period average deviation and the deviations sampled during plural periods are averaged separately for the respective sections to determine section average deviations of the respective sections which are stored as basic data, the period average deviation is subtracted from the section average deviations and the resultant differences for the respective sections are stored as basic patterns, the basic data and the basic pattern stored for each section are readout at a suitable timing to be used for producing a reduction position control signal for that section, which is adapted to compensate the thickness variation of the rolled material when rolled under that section.

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.
