[0004] Electric arc furnace steelmaking requires a large amount of electric energy to be converted into heat energy. During the smelting process, the heat energy of the high-temperature furnace liquid is not well utilized, and most of it is lost in the air. If this part of heat energy is utilized in the long run, it will save a lot of energy.

The invention relates to the field of metal smelting, in particular to an electric arc furnace utilizing waste heat. Utilize the heat when the furnace liquid comes out of the furnace and the high-temperature heat energy of the furnace body during smelting to preheat the charge to be added to realize full utilization of energy. It includes a furnace body, a furnace mouth and a liquid outlet track. The furnace mouth is located at the bottom of the furnace body near the side wall, and the liquid outlet track is located directly below the furnace mouth. The feeding device, the heat collecting port of the heat collecting chamber is installed on the liquid outlet track, the heat conduction port is connected with the bottom plate of the feeding device, and the discharge port of the feeding device is connected with the furnace door. Reasonable use of waste heat to preheat the newly added charge is structurally achievable, greatly saving energy and improving organizational performance in the smelting process.
Description
technical field [0001] The invention relates to the field of metal smelting, in particular to an electric arc furnace utilizing waste heat. Background technique [0002] Metal smelting technology is widely used in my country, especially steelmaking technology is a research project that my country is committed to. [0003] At present, most domestic enterprises adopt the electric arc furnace steelmaking method. The electric arc furnace (EAF) steelmaking method uses electric energy as the heat source for steelmaking. It is a steelmaking method that heats and melts the metal charge and slag by means of arc radiation and direct action of the arc, and smelts various qualified steel and alloys. [0004] Electric arc furnace steelmaking requires a large amount of electric energy to be converted into heat energy. During the smelting process, the heat energy of the high-temperature furnace liquid is not well utilized, and most of it is lost in the air. If this part of heat energy is ...
