Product Description
Aluminum Ash Treatment Electric Furnace (Calcium Aluminate Furnace)
Aluminum Ash Detoxification · Pre-Melted Refining Slag · High-Temperature Melting · Energy Saving & Low Consumption · Solid Waste Recycling
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.
Product Uses: Steelmaking deoxidizer & desulfurizer, ladle refining slag, cement/refractory raw material.
Applications: Aluminum smelters, aluminum processing enterprises, hazardous waste disposal centers, metallurgical auxiliary material plants.
