Brief introduction of submerged arc furnace 

Submerged arc furnace is a kind of industrial furnace which consumes much power. Full set 

equipment mainly consist of furnace shell, fume hoods, lining, short net. cooling system, exhaust system,

de -dusting system, electrode shell, electrode lifting system. loading and unloading system. 

Product Description 

Electric arc furnace is an electric furnace for smelting ores and metals at high temperature produced by 

electrode arc. When gas discharge forms arc, the energy is very concentrated , and the temperature of arc 

region is above 3000 C. For smelting metals, EAF is more flexible than other steelmaking furnace. It can 

effectively remove impurities such as sulfur and phosporus.

Electric arc furnace is an electric furnace for smelting ores and metals at high temperature 

produced by electrode ar. When gas discharge forms arc, the energy  is very concentrated, 

and the temperature of arc region is above 3000C, For smetling metals, EAF is more flexible  

than other  steelmaking furnaces.  It can effectively remove impurities such as sulfur and 

phosphorus. The furnace temperature is easy to control and the equipment occupies a small 

area. It is suitable for smlting high quality alloy steel.
