Product Introduction
Submerged arc furnace is also known as electric arc furnace or resistance electric furnace. It is mainly used
to reduce smelting ore, carbonaceous reducting agent and solvent etc. Mainly adapt to production of
ferromanganese, ferrochrome, silicon mangansese alloy and other ferrous alloy.
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.

Construction :
An electric arc furnace used for steelmaking consists of a refractory -lined vessel, usually water -
cooled in large sizes, coverded with a retractable roof, and through which one or more graphite
electrode enter the furnace. The furnace is primarily split into three sections.
The shell,which consists of the sidewalls and lower steel bowl
The hearth, 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 the refractory delta in
its center, through which one or more graphite elctrodes enter.
Submerged arc furnace equipment is divided into three layer arrangement
The first layer is furnace body (including furnace bottom support, furnace shell, furnace lining)
tapping system ( including the ladle or pot and ladle car ) arc burner etc.
The second layer
1) Fume hood
