发明名称 METHOD FOR RECOVERING MANGANESE FROM SLAG PRODUCED WHEN MANUFACTURING MANGANESE-BASED FERROALLOY
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a recovery method which can reduce manganese oxide in slag produced after having produced ferromanganese or silicon-manganese with a smelting reduction process, at a high reduction rate, when using the slag in a steelmaking process. <P>SOLUTION: The method for recovering manganese from the slag comprises the steps of: melting the slag 10 added onto molten steel 9 when refining the molten steel in a ladle refining furnace 1 in the steelmaking process under an inert gas atmosphere; reducing the manganese oxide in the slag to recover manganese; and returning it into the molten steel. In the method, it is preferable to add the slag on the molten steel before starting the refining of the molten steel in the ladle refining furnace or while refining it. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p>
