Abstract
PURPOSE:To perform always stable rolling for extremely improving the accuracy of thickness and shape of the product, by measuring the surface roughness of the material and the surface roughness of the work roll, and by carrying out operation for setting the roll gap and the revolving speed of the roll. CONSTITUTION:The surface roughness of the rolled sheet 8 is measured by the surface roughness tester 10; this measured value together with the surface roughness of the work roll are inputted to the arithmetic control unit 100. The unit 100 operates the friction factor against the sheet and the value of deformation resistance at the rolling work. Next, the rolling load and the rolling torque are operated according to the data obtained from above operations. Basing on these data, are operated the roll gap and the revolving speed of the roll corresponding to the output of the motor for driving the mill, on purpose to obtain the aim thickness of the sheet on the exit side. The signals corresponding to the results of these operations are delivered from the arithmetic control unit 100 to the roll gap controller 11 and the roll revolving speed controller 31, and those controllers 11, 31, respectively set the aim value.
