Product Description

Submerged arc furnace Profile
Submerged arc furnace—it's also known as electric arc furnace or resistance electric furnace. It is mainly used to reducing smelting ore, carbonaceous reducing agent and solvent etc. Mainly adapt to production of ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicon manganese alloy and other ferrous alloys, it is an important smelting furnace in metallurgical industry for production of industrial raw materials and calcium carbide and so on chemical raw materials. The working character is to use carbon or magnesia refractory materials as furnace lining, use self roasting electrode. Electrode insert into the materials inside the furnace for submerged arc operation, using arc energy and current through the materials, and due to the resistance of the materials and produce energy to melt metal. It's a kind of industrial furnace which is worked continuously, charge material in succession, and tap out metal or slag in intermittent.

Submerged Arc Furnace---Structure characteristics
Submerged arc furnace is a kind of industrial furnace which consumes much power. Full set equipment mainly consists of furnace shell, fume hoods, lining, short net, cooling system, exhaust system, de-dusting system, electrode shell, electrode lifting system, loading and unloading system, electrode holder, arc burner, hydraulic systems, submerged arc furnace transformer and various of electrical equipments.
Submerged arc furnace equipment is divided into three layer arrangement
The 1st 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 2nd layer
(1) Fume hood: At present, mostly of submerged arc furnace adopt closed or semi-closed low hood structure, with the characteristics of environmental protection, facilitate maintenance and improve the operation environment. The closed structure can also collect the exhaust gas (main ingredient is carbon monoxide) which is generated in the production and use in synthetically. Also can reduce the heat loss of the circuit, decrease the temperature of the electrode, and improve the operating environment.
(2) Electrode holder: Most of submerged arc furnace with three-phase power supply. Electrode in triangle or inverted triangle, symmetrical position placed in the middle of furnace chamber. Large submerged arc furnace generally adopt anthracite, coke and coal tar pitch mixed as electrode material, in the process of smelting , it roasting by itself as electrode.
