Abstract
A cooling water temperature control method, includes: calculating thickness of a water film remaining on a steel sheet; calculating a change in the thickness of the water film; calculating a change in temperature of the steel sheet; calculating a steel sheet temperature on an exit side of a draining roll at which a position where the thickness of the water film on the steel sheet becomes zero coincides with an exit side position of a drying equipment, and setting the calculated temperature to a lower limit value; calculating a steel sheet temperature on the exit side of the draining roll at which the steel sheet temperature on the entrance side of coating equipment coincides with a predetermined temperature and setting the calculated temperature to an upper limit value; and controlling the temperature of cooling water within a range of the lower limit value and the upper limit value.
