PURPOSE: To prevent the clogging of a nozzle and the splashing of molten steel at the start of casting and to stabilize casting by making the flow rate of charging of the molten steel at the start of continuous casting smaller than a specified flow rate.
CONSTITUTION: A rod 13 which supports and guides a tundish stopper 4 and a beating bar which forms said rod in one body and is mounted in one body to a lever 12 and the rod 13 are moved upward by a cylinder 16 at the start of continuous casting. The rate of the ascending is regulated by a cylinder 1 to make the rate of charging of molten steel smaller than a specified flow rate. The controlling is carried out until the tip part of a charging nozzle 9 disposed in the mold is immersed in the molten steel. By said charging method for molten steel, the molten steel is killed without splashes, and a large amt. of the molten steel can be charged satisfactorily, whereby high-speed casting is realized.
