Abstract

PURPOSE: To obtain slag hard to weather as well as refine molten steel by adding Al and Al2 O3 to slag contg. more than a fixed ratio of CaO,a prescribed range of Al2 O3 and less than a fixed amt. of SiO2 used in reduction refining of molten steel and mixing them so that the total amt. of A 2 O3 becomes a fixed range after which the mixt. is added to other molten steel.
