The aluminum ash treatment electric furnace (also known as calcium aluminate furnace, pre-melted refining slag arc furnace, aluminum ash melting detox furnace) is the core thermal equipment for aluminum ash hazardous waste recycling. It is specially designed for primary aluminum ash, secondary aluminum ash, aluminum slag, aluminum ash powder. Through high-temperature melting, slagging and reaction synthesis at 1500–1800℃, Al₂O₃ and CaO in aluminum ash react to form calcium aluminate (pre-melted refining slag). Meanwhile, fluorine/nitrogen/salt harmful substances are solidified and metallic aluminum is recovered, realizing triple values of hazardous waste detoxification + high-value products + zero discharge.
Control Mode: Fully automatic PLC + manual dual mode
2.4 Environmental Protection & Energy Consumption
Dust Emission: ≤10mg/m³
Fluoride Emission: ≤3mg/m³
Tailings Utilization Rate: 100% (calcium aluminate products for sale)
3. Core Advantages
Hazardous Waste Detoxification, High-Value Conversion: High-temperature melting fixes fluorine/nitrogen/salt, aluminum ash becomes steelmaking pre-melted slag, value increased by 3–5 times per ton.
High Efficiency & Energy Saving, Low-Cost Operation: DC furnace saves 15% power, 35% electrodes, 20% capacity vs AC furnace; electromagnetic stirring for more complete reaction.
High-Temperature Melting, Stable Quality: Pre-melted at 1500–1800℃, uniform composition, low melting point, fast melting, high deoxidation/desulfurization efficiency.
High Customization & Wide Adaptability: Customized by aluminum ash composition, capacity and environmental requirements, suitable for small to large aluminum plant solid waste treatment.
