Title:
THICKNESS SCHEDULE COMPUTING METHOD FOR TANDEM ROLLING MILL, AND ROLLING PLANT
Document Type and Number:
WIPO Patent Application WO/2024/023910
Kind Code:
A1
Abstract:
The present disclosure provides a thickness schedule calculation method and a rolling plant that make it possible to calculate and set a limit value for a limit check that is preferable for maintaining a stable rolling and operating state with reduced rolling troubles. The thickness schedule computing method comprises a computing step of computing a thickness schedule by using a rolling model formula including a forward slip model and a rolling load model, on the basis of a rolling load or motor power. The computing step includes a calculating step of calculating at least one of an upper limit value and a lower limit value of the rolling reduction ratio in each rolling stand on the basis of past rolling data, for each product specifications including a steel type category for rolling and a thickness category, and a setting step of setting at least one of the upper limit value and the lower limit value calculated in the calculating step as a limit value for a limit check with respect to the rolling reduction ratio.
