Zusammenfassung:PROBLEM TO BE SOLVED: To improve the accuracy of thickness in a material difficult to be rolled while preventing troubles due to slip and rupture in a stand and reduction of area in the stand. SOLUTION: When performing continuous rolling by changing the thickness in running, the target value in thickness control at an intermediated stand 13 is changed to the present value at that time at the point t3 of time when thickness deviation on the outlet side of the final stand falls in a specified range.
