METHOD OF REMOVING TITANIUM FROM HIGH-CHROMIUM MELTS

摘要

FIELD: metallurgy.SUBSTANCE: method comprises tapping metal from furnace to ladle, building CaO-SiO-MgO-system slag up on metal melt surface, and adding iron chloride as chlorinating agent to liquid slag. Then, melts are soaked to termination of reaction of titanium removal from metal in gas phase in the form of volatile titanium chloride. To accelerate reaction of refinement and removal of titanium chlorides from reaction zone, the melts are blown by neutral gases, for example, argon or carbon oxide.EFFECT: higher quality and efficiency, nonpolluting process.3 cl, 1 tbl
