Abstract:
    The invention is to improve magnetic characteristics and shape quality by simultaneously controlling both of strip temperature and temperature distribution in a width direction of a rolling material and strip shape of the rolling material. A coolant jet command computation unit (51) calculates a widthwise deviation of shape of the rolling material (2) detected by a shape detector (32), and widthwise deviation of temperature distribution of the rolling material detected by a strip temperature distribution detector (41) and obtains a widthwise distribution of coolant jetting level which is a necessary level for coolant jetted from a coolant jet nozzles (9). Then, based on the obtained widthwise distribution of coolant jetting level, control information for the coolant jetting nozzle (9) to jet the coolant is set up, and based on the control information set up, an ON/OFF command for coolant jetting is issued to coolant valves (8).
