6300kVA~63000kVA Submerged Arc Furnace/Electric Arc Furnace/Ore Melting Furnace

Submerged arc furnace is also called electric arc furnace or electric resistance furnace. It is mainly used to restore smelt ore as well as the material of carbonaceous reducing agent and rholite. Submerged arc furnace mainly produces silicon iron, ferromanganese iron, chromium iron, ferrotungsten, silicon-manganese alloy and other ferroalloys. The operating features are that carbon or magnesia refractory is used in lining of furnace and that electrode is used. The electrode is inserted into furnace charge to for submerged arc operation. It is a kind of industrial electric furnace making use of the arc energy and energy producing by current through the furnace charge. It has the function of continuous feeding charge, intermittent slagging and continuous operation.

Features:
Short net of ferro-alloy submerged arc furnace is arranged as inverted triangle. Calcium carbide furnace is arranged as erected triangle. The reasonable design shortens distances of short net, reduces the length gap of three-phase copper tile, and reaches the highest power factor. Copper pipe is used thin-wall copper pipe and the arrangement is adopt double wire system. 180 degrees of compensation makes magnetic field counteracted. Water cooling can keep short net operating at low temperature, reduce troubles and improve the operation efficiency of system. The choice of main technical parameters of furnace body and electrical parameters is reasonable and practical. Electrode system adopts international advanced demag technology, South Africa PYROMET technology, etc. For example, hanging cylinder type electrode lifting device is adopted, which has reliable performance and can adjust up and down position of electrode.

Types of submerged arc furnace:
Silicomanganese furnace, high carbon ferromanganese furnace, medium and low carbon ferromanganese furnace, ferrosilicon furnace, ferronickel furnace, ferrochromium furnace, high carbon ferrochromium furnace, medium carbon ferrochromium furnace, micro-carbon ferrochromium furnace, silicon chromium alloy furnace, industrial silicon furnace, calcium carbide furnace, silicocalcium furnace, silicon aluminum alloy furnace, etc.

Constitution:
Furnace shell, smoke extraction system, short net, control system, tapping system, charging system, discharging system, water cooling system, hydraulic system, air-operated system, batching station, high voltage electrical system, low voltage electrical system, automation system and upper computer control system.
