CONTROL METHOD AND CONTROL METHOD OF TEMPER ROLLING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To impart a target elongation percentage to a steel strip with high accuracy by performing temper rolling of the steel strip with a proper rolling load, and make a shape of the steel strip flat.SOLUTION: A weight coefficient calculation part 22 calculates an operation factor setting condition stored in an operation performance database 21 and a weight coefficient wfor each performance elongation percentage by using a degree of similarity wand a weight won time space. A rolling load setting calculation part 23 calculates a rolling load estimated value &phgr;of the next coil to be rolled from performance rolling loads of a plurality of coils in the past operation which are stored in the operation performance database 21 by using the weight coefficient wcalculated by the weight coefficient calculation part 22. An operation calculator 10 controls the temper rolling of the next coil in accordance with the rolling load estimated value &phgr;calculated by the rolling load setting calculation part 23.
