The Role of the Double-Well Vortex Reverberatory Furnace in Aluminum Melting
The Double-Well Vortex Reverberatory Furnace is a cutting-edge solution in the field of aluminum recycling and melting. Designed to maximize efficiency, reduce oxidation loss, and improve metal recovery rates, this furnace has become a preferred choice for processing aluminum scrap, chips, foil, and powder.
Vortex Technology: Minimizing Oxidation, Maximizing Recovery
At the core of this furnace is its vortex stirring mechanism, located in one of the two wells (side chambers). When aluminum scrap is introduced into the vortex, the powerful stirring action forces the material to quickly submerge into the molten aluminum. This rapid immersion minimizes contact with air and flame, significantly reducing oxidation and burning losses.
Recovery rates can reach up to 96%, far exceeding traditional crucible or rotary furnaces.
Oxidation loss is reduced by over 50%, preserving valuable metal content.
Dual-Well Design: Separation of Feeding and Holding
The furnace features two distinct wells:
Sidewell (Feeding Chamber) – where aluminum scrap is introduced and stirred into the melt.
Main Chamber (Holding Chamber) – where molten aluminum is heated, held, and tapped.
This separation allows for:
Continuous feeding without interrupting the melting process.
Stable temperature control and reduced thermal shock.
Improved safety and operational efficiency.
Energy Efficiency and Environmental Benefits
Equipped with regenerative burners and advanced insulation, the Double-Well Vortex Furnace offers:
Fuel savings of 20–30% compared to conventional designs.
Lower emissions, making it environmentally friendly.
24-hour continuous operation, ideal for industrial-scale aluminum recycling.
Versatile Applications
This furnace is suitable for melting:
Aluminum chips and turnings
Foil and powder
Used beverage cans (UBC)
Large aluminum blocks and castings
Its modular design allows for capacities ranging from 3 to 15 tons, making it adaptable for both small and large-scale operations.
