Submerged arc furnace's introduction

What is ferrosilicon furnace?

Submerged arc furnace is also called electric arc furnace or resistance furnace. It is mainly used for reducing smelting ore, carbonaceous reducing agent, solvent and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochromium, ferrotungsten, silicon manganese alloy and other ferroalloys. It is an important industrial raw material in metallurgical industry and chemical raw materials such as calcium carbide. 

The load of submerged arc furnace transformer is continuous and stable, the impedance voltage is low, the number of voltage regulation stages is large, the level difference is small, and the overload capacity is strong. It can be divided into on load and off excitation voltage regulation. Generally, the first few stages have constant capacity output and the last few stages have constant current output.

It is characterized by using carbon or magnesium refractory as furnace lining and self-cultivation electrode. The electrode is inserted into the charge for submerged arc operation. The energy and current of the arc are used to pass through the charge, and the energy generated by the resistance of the charge is used to smelt the metal. It is an industrial electric furnace for continuous operation with continuous feeding and intermittent iron slag discharge.
