Claim:
A method for treatment of chrome-containing molten iron and slag, Comprising mechanically stirring a chrome-containing molten iron produced in an electric furnace and having a Cr content of from 8.0 to 35.0% by mass, and a Ca F2-free electric furnace slag formed during the molten iron production including Cr 2 O 3 , SiO 2 and CaO as constituent components and having a basicity CaO/SiO 2 of from 0.7 to 1.7, with an impeller in a refining vessel, wherein a metal Al-containing substance, which is a reducing agent of Cr 2 O 3 , and CaO are put into the vessel before the end of stirring to thereby control the basicity of the slag after the end of stirring to at least 1.9.
