DC Corundum Arc Furnace 3 MVA Smelting System for Hazardous Waste Metal Recovery

DC Corundum Arc Furnace for Hazardous Waste Metal Recovery

The CD-DCA-3M DC Corundum Arc Furnace is purpose built to smelt solid hazardous waste slag and recover valuable metals such as copper, nickel and iron. A high-purity corundum refractory lining protects the furnace body against aggressive molten slag, while DC arc heating delivers rapid, controllable melting.

Key Features

• Corundum Refractory Lining: Dense corundum brick work resists chemical attack and thermal cycling, reducing relining frequency and downtime.
• High Metal Recovery: Optimised slag chemistry and bath control recover up to 98 percent of valuable metals from waste streams.
• Stable DC Power: Natural power factor above 0.9 without compensation, plus low electrode consumption and reduced flicker.
• Robust Electrode System: Hydraulic electrode clamping with PLC control enables reliable voltage discharge and steady operation.
• Sealed Furnace Hood: Semi-closed low hood design captures off-gas for downstream treatment and improves working conditions.

Applications

• Metal recovery from hazardous waste slag and residues
• Smelting of non-ferrous metal bearing waste and tailings
• Co-processing of industrial solid waste in a closed loop

Why Choose This Furnace

By combining a durable corundum lining with efficient DC arc melting, this system lowers operating cost per tonne while meeting strict environmental standards. Custom power ratings and capacity upgrades are available on request.
