METHOD FOR CONTROLLING WIDTH OF PLATE IN HOT FINISH ROLLING

摘要

PURPOSE: To provide a method for controlling the width of a plate by a feedback system, which is free from hunting. ;CONSTITUTION: When controlling the width of the plate of a material S to be rolled by changing tension between a first stand #1 and a second stand #2, a control period after increasing the tension, is made to be ≥1/2 of a time required for the transfer of the material S to be rolled, between the first stand #1 and a width gage 11. Also, a control period after decreasing the tension, is made to be a time or more required for the transfer of the material S to be rolled, between the first stand #1 and the width gage 11.;COPYRIGHT: (C)1995,JPO
