CONTINUOUS ROLLING METHOD AND DEVICE THEREFOR

PROBLEM TO BE SOLVED: To provide a continuous rolling method by which errors due to a rolling model equation and errors due to the temp. of a material to be rolled are reduced and the material to be rolled is continuously rolled so that the rolling load at each stand becomes a ratio required and a device used for the execution of the method. SOLUTION: In a rolling load calculating part 3, the 2nd rolling information and target thickness hi are substituted in the rolling model equation and the rolling load Pi at each stand No.1-7 is calculated. In a target thickness correcting part 5, a ratio λi in accordance with the dimensions and components of the material S to be rolled is read out from a ratio setting part 4 and also the target thickness hi is read out from the target thickness calculating part 2 and, using the rolling load Pi and ratio λi which are given from the rolling load calculating part 3 and the equation, the amount Δhi of correction of the target thickness is calculated and the target thickness hi is corrected by this amount Δhi of correction of the target thickness.
