  • Control Of Metal Rolling (AREA)

Abstract

PURPOSE: To improve accuracy of the thickness of plate, by bringing the thickness of plate and the tension of rolling materials into aimed ranges by successively repeating the load control, tension control, and thickness control after the rear end of rolling materials passed through the preceding stand.
CONSTITUTION: After the rear end of a rolling material passed through the pay-off reel or the preceding stand, the rolling load of the stand located at the most upper stream is detected, and the load control is repeated so that the rolling load may fall in an aimed range. Then, the tension control is performed by adjusting the rolling speed so that the tension of the rolling material between adjacent stands may fall in an aimed range, and moreover, the thickness of the rolling material between adjacent stands is also controlled. Then, at the same time, the thickness of the rolling material and the tension between each adjacent stand at the downstream side of said stand are adjusted so that they may fall in aimed ranges.
