ABSTRACT:
An automatic casting process of a continuous casting machine includes a mold filling mode and a continuous casting mode. The continuous casting machine includes a metallurgical vessel having a discharge opening, a stopper for opening and closing to an affective flow rate of a molten metal from the discharge opening, and a control device for controlling the opening and closing of the stopper. The mold filling mode of the automatic casting process entails repeatedly opening and closing the stopper to discharge the molten metal into a continuous casting mold having an extracting end sealed by a starting head. The opening and closing of the stopper during the mold filling mode is effected at predetermined time intervals and at predetermined stopper positions which are preprogrammed in the control device. The level of the molten metal within the continuous casting mold is monitored, and when the monitored level reaches a predetermined level, the mold filling mode is terminated, the starting head is withdrawn from the extracting end of the continuous casting mold, and the continuous casting mode of controlling the stopper position is initiated to maintain the predetermined level of the molten metal within the continuous casting mold.
