Abstract

PURPOSE: To effectively improve utilization efficiency of desulfurizing agents for molten crude iron, by dissolving uniformly Al in in amounts to be consumed in a desulfurizing reaction and to inphibit oxidation of Si preveously into the molten crude iron, and by blowing a CaO type desulfurizer into the obtained mixture.
