Abstract
PURPOSE: To prevent the degradation in the quality of continuously cast ingots and the clogging of a tundish nozzle by adding the molten steel left in a ladle to the ladles after the next charge, and subjecting this to vacuum degassing treatment then pouring this molten steel, in pouring the molten steel in plural ladles successively into the same tundish at the continuous casting of steel.
CONSTITUTION: Molten metal is poured successively and continuously from plural ladles into the tundish used with a continuously casting device. At this time, the pouring is stopped by leaving 3W20% the molten steel in the pouring ladle to prevent molten slag from entering the tundish. The 3W20% residual molten steel is added to the molten steel of the next and subsequent ladles, and this molten steel is subjected to vacuum degassing treatment. Further, Al is added thereto and remove the Al2O3 as a nonmetallic compound in the molten steel and control the components thereof. The continuously cast ingot is a clean steel ingot without containing the Al2O3 as a nonmetallic compound and the tundish is prevented from being clogged by the Al2O3.
