The steelmaking electric arc furnace uses electricity as the main energy source. Electric energy is discharged through graphite electrodes and furnace materials to generate high temperatures of up to 2000-6000 ℃, melting scrap steel raw materials through arc radiation, temperature convection, and heat conduction. During most of the time when the furnace charge is melted, the high-temperature heat source is surrounded by the furnace charge, and the heat loss caused by high-temperature exhaust gas is relatively small, so the thermal efficiency is higher than other steelmaking equipment such as converters. In addition, electric heating is easy to control the furnace temperature and can be operated under any conditions such as oxidizing or reducing atmosphere, normal pressure or vacuum according to process requirements.

The electric arc furnace steelmaking process has a short process flow, simple equipment, easy operation, relatively easy pollution control, low construction investment, small footprint, and does not require reliance on complex ironmaking systems like converter steelmaking. Due to the controllable atmosphere inside the steelmaking electric arc furnace, the operation of slag adjustment or replacement is relatively easy, and complex process operations such as melting, decarburization, dephosphorization, degassing, inclusions removal, temperature control, and composition adjustment (alloying) can be completed in the same operating system. Electric arc furnace steelmaking can produce intermittently and flexibly switch production varieties within a certain range.

In addition, modern electric arc furnaces can also use a large amount of auxiliary energy, such as injecting heavy (light) oil, coal powder, natural gas, etc. Therefore, the electric arc furnace steelmaking process has strong adaptability, flexible operation, and wide application. Electric arc furnaces can not only smelt excellent steel with low phosphorus, sulfur, and oxygen content, but also alloy various elements to produce various excellent steels and alloy steels, such as ball bearing steel, stainless acid resistant steel, tool steel, electrical steel, heat-resistant steel, magnetic materials, and special alloys.
