An arc is an arc discharge of a gas. Gas arc discharge is characterized by low voltage between electrodes, large current through the gas, bright white light, high arc temperature (about 5000K). The huge current density comes from the hot electron emission of the cathode and the self-emission of th

The main raw material of electric arc furnace steelmaking is scrap steel, but the resources of scrap steel are relatively scarce at present, which hinders the development of electric arc furnace steelmaking to a certain extent. In order to solve this problem, we must find substitutes for electric ar

Electric arc furnace uses the high temperature generated by the electrode arc to smelt ores and metals. When the gas discharge forms an arc, the energy is very concentrated, and the arc zone temperature is above 3000 ℃. For smelting metals, electric arc furnaces are more flexible than other steelmak
