Abstract

PURPOSE: To perform the effective tension control, by deciding the control gain correspondingly to the rolling schedule, the rolling mill characteristic, and the rolling condition at an arbitrary point of time during the rolling work, and by controlling the roll speed of each rolling mill.
CONSTITUTION: At each rolling mill of the continuous rolling facilities possessing the wide rolling condition and the rolling mill characteristic, the influence factors αi, βi, are obtained from the mean deformation-resistance K of the rolled material, the sheet breadth W, the mill constant M of the rolling mill, etc. From this result, the roll speed of each rolling mill is controlled by the control gain ki,i+1 depending on the characteristic of the control object to be obtained from the formula I at an arbitrary point of time during the rolling work.
