Solid Hazardous Waste Corundum Electric Furnace 5 Tph for Slag Vitrification

Corundum Electric Furnace for Solid Hazardous Waste Vitrification

The CD-CF-5T Corundum Electric Furnace is engineered for continuous high-temperature melting and vitrification of solid hazardous waste, industrial slag and smelting residues. The corundum-lined melting chamber withstands thermal loads up to 2000 C, enabling stable, low-emission waste processing and inert slag output.

Key Features

• Corundum-Mullite Lining: High-purity corundum castable lining resists slag erosion and thermal shock, extending campaign life beyond three years.
• DC Arc Heating: Concentrated DC arc heat reaches high melting point materials quickly, with power factor above 0.9 and no reactive compensation required.
• Continuous Operation: Automatic feeding, tapping and slag discharge support 5 tonnes per hour with a closed furnace hood for dust control.
• Smart Control: PLC plus frequency conversion electrode lifting gives double closed-loop control of current and voltage.
• Energy Saving: Electrode consumption is only 30-50 percent of a comparable AC furnace, with low flicker and noise.

Applications

• Vitrification of solid hazardous waste and contaminated soil
• Melting of industrial slag, tailings and smelting residue
• Stabilisation of heavy-metal bearing waste into inert glassy slag

Why Choose This Furnace

Clean electrical heating avoids fossil fuel combustion and sharply reduces SO2, NOx and dust emissions. The corundum lining and water-cooled shell combine to deliver a long service life with minimal maintenance downtime.
