— HU Xian-leiL3’ introduced an optimization method of holding temperature and thickness for pass schedule calculation of two-phase controlled rolling on plate mill. However, for hot tandem roll- ing mill the capacity of shape control is not inex- haustible, and it is necessary to take into account shape control in rolling schedule.
