Abstract

PURPOSE: To prevent the degradation of the quality of continuously cast ingots and the clogging of a tundish nozzle by adding the molten metal left in the ladle to the 3rd ladle after one in pouring the molten metal in the plural ladles successively to the same tundish at the continuous casting of steel.
CONSTITUTION: Molten steel is poured successively and continuously from plural ladles into the tundish used in a continuous casting device. At this time, the pouring is stopped by leaving 3W20% the molten steel in the first ladle to prevent molten slag from entering the tundish. Since adding the residual molten steel in the next ladle requires a hoisting device for hoisting the same further upward, said steel is added into the 3rd ladle to eliminate the need for extra hoisting device. The molten steel in the 3rd ladle added with the residual molten steel is subjected to bubbling treatment and Al addition, whereby the Al2O3 produced at the adding of the residual molten steel is slagged, cleaned and component-controlled, thus the degradation of the quality of the continuously cast ingots and the clogging of the tundish nozzle by Al2O3 are prevented.
