Electric arc furnace is an electric furnace that uses the high temperature produced by electrode arc to melt ores and metals. The energy is very concentrated when the gas discharge forms the arc, and the temperature of the arc area is above 3000 ℃. For metal smelting, the electric arc furnace is more flexible than other steelmaking furnaces, which can effectively remove sulfur, phosphorus and other impurities. The furnace temperature is easy to control, and the equipment occupies a small area, which is suitable for smelting high-quality alloy steel.

Converter steelmaking is the process of converting molten iron from the blast furnace into oxygen. The furnace body can rotate. The steel plate is used as the shell, and the refractory material is used as the lining. During converter steelmaking, there is no need to heat the molten iron, because the molten iron itself is high temperature, and the oxidation reaction of heating continues inside.
