Equipment Description
Submerged melting furnace, also known as electric arc furnace or resistance furnace. It is
mainly used for the reduction of smelting ores, carbon reductants and solvents 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.
Contruction
Submerged arc furnace used for steelmaking consists of a refractory-lined vessel, usually water
cooled in large size, covered with a retractable roof, and through which one or more graphite
electrodes enter the furnace. The furnace is primarily split into three sections :
Furnace main body electrical equipment
1 High voltage cabinet and cable crane span structure
2 low voltage cabinet, front furnace operation platform, PLC cabinet
3 Power and control cable, lighting distribution box
4 Furnace transformer
Electric furnace main mechanical equipment
1 Furnace body rotation

Application of submerged arc furnace
Submerged arc furnace is using electricity as the fuel source, and utilizes the arc high
temperature produced by electrode and furance charge to heat and melts the furnace
charge.
