High-carbon and charge chrome alloys are generally produced in the conventional smelting process by carbothermic reduction of ferrochrome ores using AC submerged-arc and DC open-arc electric furnaces. In AC submerged-arc furnaces, the energy to the furnace is predominantly supplied in a resistive heating mode.
The instant invention is a process for preparing silicon metal in a direct current, submerged-arc furnace. The process comprises adding a source of silicon dioxide and a source of carbon to a substantially closed furnace. Heat is provided to the furnace by striking a direct current arc between a moveable cathode and a anode functional hearth.
smelting of aluminium process through submerged arc furance. ... technology for ferroalloy smelting is the submerged arc furnace. However, for some specific applications and electrical grid conditions, the DC-arc furnace, operating in open arc proves to be more cost efficient. MFC has waste experience in operating both types of furnaces.

The energy ... system is except for CaCz smelting not used for submerged arc furnaces. The submerged furnace canbe characterized by:
Continuous process furnaces may also use paste-type, Søderberg electrodes to prevent interruptions due to electrode changes. Such a furnace is known as a submerged arc furnace because the electrode tips are buried in the slag/charge, and arcing occurs through the slag, between the matte and the electrode. A steelmaking arc furnace, by ...

The furnace is similar to traditional electric furnaces in that it utilizes electrodes for the melting process. The liquid hot metal that is produced by the furnace can be used as hot metal feed for an electric arc furnace (EAF) or the hot metal can be directly cast as pig iron using a pig casting machine.
