Product Description  

Submerged arc furnace, is also known as electric arc furnace or resistance furnace. It is mainly 

used for the reduction of smelting ores, carbon reductants and solvent etc. It is mainly for 

production of ferrosilicon, ferromanganese,ferrochromium,tungsten iron, silicon and 

manganese alloy and other ferroalloy, all above are important industrial raw materials 

and calcium carbide and other chemical raw materials in metallurgical industry.

 Construction 

 Submerged arc furnace used for steelmaking consists of a refractory-lined vessel, usually water 

 cooled in large sizes,covered with a retractable roof, and through which one or more  graphite 

 electrodes enter the furnace. The furnace is primarily split into three sections :

 The shell , which consists of the sidewalls and lower steel bowl. 

 The heath, which consists of the refractory that lines the lower bowl. 

 The roof, which may be refractory-lined or water cooled, and can be shaped as a section of  a 

sphere, or as a frustum (conical section). The roof also supports teh refractory delta in its center, 

through which one or more graphite electrodes enter.

   Introduction of Arc furnace 

  Application of Electric Arc Furnace 

   Electric arc furnace is using electricity as the fuel source, and utilized the arc high temperature 

   produced by electrode and furnace charge to heat and melts the furnace charge . It is widely  

  using  in the production of normal steel, high quality carbon steel, various alloy steel.  It is the 

  key equipment in steel making factories, foundry factories, ferrous alloy making factories and

  etc.
