The steelmaking electric arc furnaces (EAF) is a device that uses electric arc discharge to generate high temperature for steelmaking. Its working principle is to generate high temperature up to 4000℃ through electric arc to melt metal materials.
The steelmaking process is usually divided into melting period, oxidation period and reduction period. The oxidation and reduction atmosphere can be controlled in the electric furnace to effectively dephosphorize and desulfurize.
EAF is suitable for refining various steel grades, from plain carbon steel to high alloy steel and stainless steel. Advanced oxygen blowing and carbon injection technology can further improve the performance of steelmaking electric furnaces.
