METHOD FOR CONTROLLING SHAPE OF ROLLING SHEET AND METHOD FOR MANUFACTURING ROLLING SHEET IN ROLL CROSS TYPE ROLLING MILL

摘要

PROBLEM TO BE SOLVED: To provide a method for controlling a shape of rolling sheet and a method for manufacturing the rolling sheet in a roll cross type rolling mill using the method for controlling the shape capable of improving the precision when controlling the shape of rolling sheet by manipulating a crossing angle of the roll cross type rolling mill under rolling.;SOLUTION: A method for controlling a shape of rolling sheet and a method for manufacturing the rolling sheet in a roll cross type rolling mill using the method for controlling the shape is that a control gain when making decision of manipulated variable of a crossing angle is to be set up as a function of the crossing angle and the manipulated variable of the crossing angle is decided by substituting an actual result value of the crossing angle into the function while the control gain is changed hourly in the method for controlling the shape of the rolling sheet by manipulating the crossing angle of the roll cross type rolling mill.;COPYRIGHT: (C)2012,JPO&INPIT
