Method for secondary utilization of thermal-state metallurgical solid waste

The invention discloses a method for secondary utilization of thermal-state metallurgical solid waste, which belongs to the technical field of ferrous metallurgy, and is characterized in that the method comprises the following steps: starting to supply power after tapping and remaining steel in an electric furnace, adding molten iron, thermal-state steel slag, a slagging material and a first batch of scrap steel into the electric furnace for melting in the early stage of smelting, after the hot-state steel slag, the slagging material and the first batch of waste steel in the early stage of smelting are molten, the water-cooling carbon-oxygen lance is started to blow oxygen and spray carbon into the electric furnace to form foamed slag, then the waste steel continues to be added for normal smelting in the melting period and the oxidation period, and the effects of improving the utilization rate of the steel slag and reducing the smelting cost are achieved. 本发明公开了一种热态冶金固废二次利用的方法，属于钢铁冶金技术领域，其技术方案要点是所述方法包括在电炉出钢并留
