METHOD FOR RECOVERY VALUABLE METALS FROM STEEL-MAKING SLAG OF STAINLESS STEEL

摘要

The present invention relates to a method for recovering valuable metals of stainless steel slag. When scrap and ferroalloy are dissolved in an electric furnace, the slag in the electric furnace is rapidly heated by an electrode rod and an assisting burner, thereby maintaining the liquid slag and reducing the liquid slag. As the slag forming operation is carried out as the material is injected, the inside of the furnace is heated evenly by the electrode rod and the supporting burner, and the slag inside the furnace is heated quickly as the temperature difference in position decreases, so the slag is optimally reduced in valuable metals. By maintaining in a high temperature liquid state that can be reacted, the recovery of valuable metals contained in the slag is increased, and the dependence of the electrode on the slag temperature is lowered to reduce the power source unit, thereby minimizing the erosion of the inner wall of the furnace It relates to a valuable metal recovery method of steelmaking slag.
