Date Apr. 24, 1997In order to control a molten metal level within a mold of a system comprising a liquid core reduction device, while controlling a fluctuation of the molten metal level caused by a change of operational conditions, such as the withdrawal rate, reduction speed, etc., with improvement of the yield rate of product slabs, a method comprises the steps of: (i) estimating a disturbance to the molten metal level, which is caused by a change in operating conditions of a continuous casting machine before changing the operating conditions; (ii) determining an amount of correction of the control signal to eliminate the disturbance, and determining a delay time of the operation of the pouring means in responses to the control signal after correction; and (iii) applying a control signal containing the amount of correction in advance by a period of the delay time prior to the occurrence of a change in operating conditions.
