HX6.3 Submerged Arc Furnace

6300KVA~63000KVA submerged arc furnace

Submerged arc furnace is also calledelectric arc furnace or electric resistance furnace. It is mainly used torestore smelt ore as well as the material of carbonaceous reducing agent andrholite. Submerged arc furnace mainly produces silicon iron, ferromanganeseiron, chromium iron, ferrotungsten, silicon-manganese alloy and otherferroalloys. The operating features are that carbon or magnesia refractory isused in lining of furnace and that electrode is used. The electrode is insertedinto furnace charge to for submerged arc operation. It is a kind of industrialelectric furnace making use of the arc energy and energy producing by currentthrough the furnace charge. It has the function of continuous feeding charge,intermittent slagging and continuous operation.

Features:

Short net of ferro-alloy submerged arcfurnace is arranged as inverted triangle. Calcium carbide furnace is arrangedas erected triangle. The reasonable design shortens distances of short net, reducesthe length gap of three-phase copper tile, and reaches the highest powerfactor. Copper pipe is used thin-wall copper pipe and the arrangement is adoptdouble wire system. 180 degrees of compensation makes magnetic fieldcounteracted. Water cooling can keep short net operating at low temperature,reduce troubles and improve the operation efficiency of system. The choice ofmain technical parameters of furnace body and electrical parameters isreasonable and practical. Electrode system adopts international advanced demagtechnology, South Africa PYROMET technology, etc. For example, hanging cylindertype electrode lifting device is adopted, which has reliable performance andcan adjust up and down position of electrode.

Typesof submerged arc furnace:

Silicomanganese furnace, high carbonferromanganese furnace, medium and low carbon ferromanganese furnace,ferrosilicon furnace, ferronickel furnace, ferrochromium furnace, high carbonferrochromium furnace, medium carbon ferrochromium furnace, micro-carbonferrochromium furnace, silicon chromium alloy furnace, industrial siliconfurnace, calcium carbide furnace, silicocalcium furnace, silicon aluminum alloyfurnace, etc.
