ABSTRACT:
A premelted synthetic slag for ladle desulfurizing molten steel and a related method for desulfurizing molten steel employ high MgO content calcium-aluminate synthetic slag. A preferred slag composition contains 0.1-3.0% by weight of vanadium oxide. A particularly preferred composition is the slag obtained from production of vanadium or ferrovanadium by aluminum reduction of vanadium oxides.
