CONTROL DEVICE & METHOD FOR ROLLING

摘要

(i) detecting depression position of each stand, roll peripheral rate, outlet plate thickness and plate rate between stands per desired cycle; (ii) memorising the detected data from the detection position of the outlet plate thickness to the following stand; (iii) transferring a record data line of the plate thickness corresponding to the plate rates detected from all stand outlets, and memorising new plate thickness; (iii) selecting the plate thickness data corresponding to the transfer distance of the rolling material transferred according to the predetermined response time of the depression device, from the following stand of the record data line; (iv) calculating a depression order being sent to the depression device performing feed-forward depression on the basis of the selected plate thickness data; and (v) repeating the steps of from (iii) to (iv).
