Structure and working principle of electric arc furnace

The electric arc furnace smelting uses the heat generated by the electric arc between the graphite electrode and the iron (molten iron) to melt the iron and overheat the iron. The three-phase arc furnace is widely used in production, and the structure of the furnace body is shown in Fig. 3. In the process of EAF smelting, when the iron is melted, the smelting operation of further increasing temperature and adjusting chemical composition is carried out under the condition that the slag covers the molten iron. According to the properties of slag and lining refractory, electric arc furnace can be divided into acid and alkaline. The basic electric arc furnace has the ability of desulfuration and dephosphorization.
