Description

Equipment Introduction and Technical Parameters


1. Equipment Introduction


The brown fused alumina furnace is a three-phase AC tilting electric arc furnace. It takes bauxite, coke (anthracite) and iron filings as raw materials, and performs reduction and melting at a high temperature above 2000℃ to produce brown fused alumina (main component Al₂O₃ ≥ 94.5%).

Mainstream model: 7500KVA, melting capacity 10–25 tons, furnace shell inner diameter 3000–3600mm.

Purpose


It is used for smelting brown fused alumina and high-alumina fused alumina abrasives and refractory materials. The products are widely applied in abrasive tools manufacturing, glass kiln refractory lining, metallurgical nozzles and wear-resistant parts.

Structural Features


  • Furnace body: Welded steel plate structure with dry composite insulation lining, thin-shell tilting design, heavy load and high temperature resistance.
  • Furnace roof: Water-cooled low smoke hood, equipped with electrode holes, feeding holes and smoke exhaust holes.
  • Discharging: Hydraulic tilting type, maximum forward tilting angle 45°, adopting continuous pouring process with low energy consumption and good crystal quality.
  • Cooling system: External spray cooling for furnace body + water cooling for furnace roof and cross arm, with pressure and temperature alarm function.

Main Components


  • Furnace Body: Welded steel shell, discharge spout, thermal insulation lining and external spray cooling system.
  • Electrode Lifting System: Hydraulic / frequency conversion drive with PLC automatic adjustment, fast response and stable control; equipped with HP high-power graphite electrodes.
  • Short Network System: Water-cooled cables and steel-copper composite cross arm, with low and balanced three-phase impedance.
  • Hydraulic System: Working pressure 12–16MPa, used for furnace body tilting and electrode clamping.
  • Feeding System: Top / side feeding mode, matched with batching bin and conveying equipment.
  • Control System: PLC + industrial computer, real-time monitoring of voltage, current, temperature and cooling parameters.

Working Principle


Three graphite electrodes generate electric arc after power-on. The ultra-high temperature above 2000℃ melts the mixed raw materials of bauxite, coke and iron filings. Reduction reaction removes impurities such as silicon, iron and titanium to form brown fused alumina molten liquid with Al₂O₃ ≥ 95%.

The molten liquid is poured, cooled, crushed and magnetic separated to obtain finished products.
