<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing stainless steel, which is capable of reducing the amount of slag to be disposed. <P>SOLUTION: This method for manufacturing the stainless steel comprises: a step of dissolving stainless steel raw material in an electric furnace 1 to produce molten iron 2; a step of decarbonizing the molten iron 2 in a revolving furnace 4 to produce stainless raw molten steel 2a; a step of adding calcium carbonate 11 and solidifying the slag 10 without the addition of a reducing agent to the slag 10 generated in the stainless raw molten steel 2a in the decarbonizing treatment; a step of separating the solidified slag 10; and a step of returning the separated slag 10 to the electric furnace 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
