<p>PURPOSE: To obtain a taper plate having the target gradient from one end toward the other end in the longitudinal direction. CONSTITUTION: This method is based on a method for controlling a roll gap based on the deviation between an estimated rolling load and a measured rolling load. In the process where the target taper thickness on the outlet side is changed according to rolling length, based on the target taper amountΔH<0> on the inlet side and target taper amountΔh<0> on the outlet side which are set with a target taper amount setting 11, mill stiffness coefficient M which is set with a constant setting 12, plasticity coefficients Q, Q' of a material 6 to be rolled and scale factor KA. which is the gain of a thickness control system, the target changing amountΔhT** of taper thickness on the outlet side is used correcting the target changing amountΔhT of taper thickness on the outlet side with a target outlet-side taper thickness changing amount setting 13.</p> |
