Product Description

Calcium Carbide Furnace electric furnaces are divided into reduction electric furnaces and refining electric furnaces. Reduction electric furnace, also known as submerged arc furnace or submerged arc furnace, adopts the submerged arc operation of inserting electrode into furnace charge. The reduction electric furnace has open, closed (or semi closed), and the furnace body has various forms such as fixation and rotation. Electric refining furnace is used to refine medium carbon, low carbon and micro carbon ferroalloys. The capacity of electric furnace is generally 1500 ~ 6000 KVA, which adopts the form of open fixing or tilting with cover. The former is similar to the reduction furnace and can be equipped with continuous self baking electrode; The latter is similar to electric arc steelmaking furnace, using graphite or carbon electrode.

8000kva Submerged arc furnace for industrial silicon melting furnace 8000kva 33000kva 60000kva 

Industrial Silicon Furnace Application: Submerged arc furnace will be mainly applied for reduction of metallurgical ore to produce the FeSi, FeMg, FeCr, Ferrotungsten, SiMg and Titanium slag alloy, which will be the important material for metallurgical and chemical industries. Features of the equipment: For submerged arc furnaces, the lining will be made of carbon or magnesia refractory material. The electrode is self-baking. The electrode will be inserted into the charging material.' The material will be molten by arc and current. The charging material will be continuously adding. The tapping will be batch type. It is a continuously operation industry furnace.
