Modern steelmaking methods mainly include converter steelmaking method, open hearth furnace steelmaking method and electric furnace steelmaking method. The open hearth furnace steelmaking method has basically been eliminated. The most fundamental difference between the electric furnace steelmaking method and the converter steelmaking method is that the electric furnace steelmaking method uses electric energy as the heat source, and the electric arc furnace steelmaking method is the most widely used electric furnace steelmaking method. What we usually call electric furnace steelmaking mainly refers to electric arc furnace steelmaking, because other types of electric furnaces (such as induction furnaces, electroslag furnaces, etc.) produce less steel.
Electric arc furnace steelmaking is based on the electric arc generated by the discharge between the electrode and the charge, so that the electric energy is converted into heat energy in the arc light, and the metal and slag are heated and melted by the direct action of radiation and electric arc, and a kind of steel and alloy of various components are smelted. A method of steelmaking.
