Product Description
50000KVA Large Submerged Arc Furnace for Ferrosilicon Smelting
This 50000KVA large submerged arc furnace is a complete ferrosilicon smelting line designed around one high-capacity furnace body. Three 1400mm self-baking electrodes work with a 110kV direct step-down transformer, so the plant avoids an intermediate voltage level and reduces line losses. A semi-closed hood with water-cooled panels captures the flue gas, and the integrated waste heat boiler recovers part of that energy for the drying and preheating stage of the raw material system.
Why a Large Submerged Arc Furnace
- Single-unit scale: 50,000 KVA in one shell delivers 100,000-120,000 tons of ferrosilicon per year, lowering fixed cost and floor space per ton of alloy.
- 110kV direct feed: the furnace transformer steps 110kV down to 210-290 V directly, removing one transformer stage and cutting no-load and line losses.
- Waste heat recovery: water-cooled hood, flue gas duct and heat exchanger support a waste heat boiler for raw material drying or low pressure steam.
- Charge distribution control: a rotating distributor and three-point feeding keep the charge cone uniform, so the electrode holes stay open and furnace permeability remains stable.
- Full automation: PLC electrode control, power load closed loop, water temperature alarm, furnace shell temperature scan and one-key shutdown interlock.
