Product Description

9000 kVA Closed Type Silicomanganese Submerged Arc Furnace

The closed type submerged arc furnace is dedicated equipment for continuous smelting of silicomanganese alloy (SiMn 6517 / FeMn64Si16). A water-cooled gas-tight furnace cover collects the CO-rich off-gas for recovery, reducing dust emission and power consumption per ton of alloy. The furnace is engineered for 24-hour continuous operation with three-phase electrode regulation, hydraulic tilting tapping and full PLC supervision.

Core Structure

  • Furnace shell: welded steel shell, diameter 6400 mm, bath depth 2400 mm, with forced water cooling on the upper shell and tap hole zone.
  • Electrode system: three self-baking (Soderberg) electrodes Ø450 mm with hydraulic clamping and slipping device; electrode paste consumption controlled by automatic slipping program.
  • Transformer: single three-phase furnace transformer 9000 kVA, 35 kV primary, secondary voltage 160-240 V in 15 steps, with on-load tap changer.
  • Short net: water-cooled copper tube busbar and flexible water-cooled cables, low reactance layout to keep the operating power factor above 0.85.
  • Hydraulic system: electrode lifting, furnace tilting and tap hole opening share one hydraulic station with proportional valve control.
  • Off-gas and dust removal: water-cooled gas-tight cover, cyclone and bag filter, air volume 45,000 m³/h, dust emission ≤10 mg/m³.

Working Principle

Raw materials (manganese ore, sinter, coke, quartzite and dolomite) are proportioned, batched and fed through the top charging pipes. The three-phase AC arc and resistance heat generated in the charge between the electrode tips melts the burden at 1600-1700 °C. Alloy and slag are separated in the furnace, alloy is tapped through the tap hole into ladles and cast into ingots, while slag is granulated and sold to the cement industry. The closed cover extracts the CO-rich gas, which is burned in a waste heat boiler or flare stack.
