Abstract

a. Procédé pour réduire les ségrégations produites par moulage continu de l'acier. b. Caractérisé en ce qu'on ajoute de l'acier froid solide dans la poche de coulée ou directement dans le moule, ce qui permet de refroidir l'acier pour éliminer la surchauffe, l'acier froid solide se présente sous la forme d'un fil, d'une tige, de copeaux de granulés, de poudre, etc.at. A process for reducing segregation produced by continuous casting of steel. b. Characterized by adding cold solid steel to the ladle or directly to the mold, which allows the steel to be cooled to eliminate overheating, the solid cold steel is in the form of a wire, rod, chips, granules, powder, etc.
