Title:
PLATE THICKNESS CONTROL DEVICE, PLATE THICKNESS CONTROL METHOD, AND PLATE THICKNESS CONTROL PROGRAMME
Document Type and Number:
WIPO Patent Application WO/2011/132273
Kind Code:
A1
Abstract:
The disclosed device comprises: a rolling load detection means (6) which detects the rolling load on a metallic material; a rolling load vertical distribution means (10) which vertically distributes the detected rolling load on the basis of a comparison of an upper side rolling load being generated by an upper side roller set and a lower side rolling load being generated by a lower side roller set; a rolling load vertical change amount extraction means (11) which extracts an upper side rolling load change amount and a lower side rolling load change amount generated in relation to the rotational position of the upper side roller set and the lower side roller set, on the basis of the vertically distributed rolling loads of the upper side roller set and the lower side roller set; a manipulation amount calculation means (12) which calculates a work roller gap command amount between an upper side work roller (3a) and a lower side work roller (3b), on the basis of the extracted upper side rolling load change amount and lower side rolling load change amount; and a roller gap manipulation means (13) which manipulates the work roller gap between the upper side work roller (3a) and the lower side work roller (3b), on the basis of the calculated work roller gap command amount.
