Regenerative Dual Chamber Aluminum Melting Furnace with 90% Recovery Rate and Heat Storage Technology
The aluminum melting furnace processes scrap aluminum or aluminum alloy materials by melting them in a molten pool, removing impurities, and adjusting alloy composition to meet technical specifications and temperature requirements. The heat preservation furnace serves as a non-ferrous metallurgical unit that heats, insulates, and exhausts aluminum or aluminum alloy solutions to maintain process conditions.
Traditional single-chamber aluminum melting furnaces combine feeding, heating, and melting processes in one chamber. While simple in design, these systems suffer from significant oxidation burn-off, particularly with lightweight and thin scrap aluminum materials where surface area exposure can lead to losses up to 20%.
Our dual chamber aluminum melting furnace addresses these limitations through innovative design:
- Central partition wall separates heating and feeding chambers
- Upper and lower channels connect furnace gas and aluminum liquid flow
- External melt pool enables continuous aluminum circulation
- Mechanical aluminum pump system facilitates material transfer
The system accommodates various material types: bulk and strip-shaped scrap aluminum can be loaded via forklift through the feeding room door, while thin and broken scrap aluminum is continuously fed through automated delivery and preheating equipment into the feeding vortex well.
The aluminum liquid mechanical pump extracts high-temperature aluminum from the heating chamber, passes it through the mechanical mixing well, enters the feeding vortex well to melt thin scrap materials, then flows into the feeding chamber to process coarse materials before returning to the heating chamber for reheating.
- Low oxidation loss with minimal material burn-off
- High aluminum liquid recovery rate exceeding 90%
- Reduced slag production and waste generation
- Superior environmental compliance and emissions control
- High melting efficiency with optimized energy consumption
- Mechanized continuous feeding reduces labor requirements
This dual chamber side pool aluminum melting furnace represents the most mature technology for online aluminum scrap recovery globally, offering significant operational and economic benefits for processors handling lightweight and broken scrap aluminum materials.
