<p><P>PROBLEM TO BE SOLVED: To provide a method for melting, decarburizing and temperature-raising molten metal containing chromium in an electric furnace while restraining oxidized loss of the chromium and iron in the molten metal, when carbon-containing iron source of molten iron, DRI, HBI, etc., are blended as the main raw material. <P>SOLUTION: The method for melting molten metal containing chromium in the electric furnace is performed, with which after charging the raw material such as scrap, ferro-alloy containing no chromium and carbon-containing iron source into the electric furnace, heating, melting and temperature-raising are performed by an electric energy and, the carbon in the molten metal is oxidized and removed, and after the molten metal temperature and carbon concentration become prescribed ones, the above raw material is melted by the electric energy while chromium containing ferro-alloy is continuously fed. <P>COPYRIGHT: (C)2004,JPO</p> |
