METHOD FOR ADDING CA IN REFINING OF STAINLESS STEEL

PURPOSE:To eliminate the loss in the addition of Ca and to improve its yield in the final stage of the refining process of stainless steel by adding Al to stainless molten steel, removing silicic acid up to a prescribed concn. and thereafter adding Ca. CONSTITUTION:In the final stage of the refining...

Zusammenfassung:	PURPOSE:To eliminate the loss in the addition of Ca and to improve its yield in the final stage of the refining process of stainless steel by adding Al to stainless molten steel, removing silicic acid up to a prescribed concn. and thereafter adding Ca. CONSTITUTION:In the final stage of the refining process of stainless steel, the molten steel in a ladle is mixed with Al to regulate the concn. of SiO2 to
