40t Natural Gas/Oil Twin Chamber Aluminum Melting Furnace

Product Description

The traditional aluminum melting furnace is of single chamber structure, which gathers feeding, heating and melting waste aluminum materials in one chamber. The advantage is that the production equipment is simple, but the disadvantage is that the burning loss is relatively large, especially for the light and thin broken waste aluminum materials. The specific surface area is large, and the oxidation burning loss of the traditional single chamber aluminum melting furnace is as high as 20%, with no compensation. Therefore, Guangzhou Longxin Company has developed a twin chamber aluminum melting furnace. A partition wall is poured in the middle of the traditional single chamber furnace. Channels are set up above and below the partition wall to connect the furnace gas and aluminum water of the two furnaces. The middle partition divides the aluminum melting furnace into two chambers, which are used as heating chamber and feeding chamber respectively. The heating room is responsible for rapidly increasing the temperature of molten aluminum; The feeding room is responsible for feeding molten waste aluminum raw materials.
The functions of the two furnaces of the twin chamber aluminum melting furnace are interchangeable. When one furnace is feeding, the other furnace is firing to melt and raise the temperature. The afterfire of the flame can be connected to the adjacent molten pool to burn organic combustibles in the light and thin aluminum scrap, greatly reducing the impact of black smoke feeding on the surrounding environment. When the temperature of molten aluminum in a furnace is raised to 720 ºC, it can stop fire, put light and thin crushed waste aluminum raw materials and scrap aluminum raw materials with iron, press the raw materials with the fork lift, bury them in the molten aluminum, form molten low temperature aluminum, and then fire again to raise the temperature. The two furnaces of the double chamber aluminum melting furnace operate in coordination with each other. The two molten pools are fed continuously in staggered time. The two sets of combustion systems are fired continuously in staggered time. On the one hand, it can improve the smelting efficiency, on the other hand, it can greatly reduce the flow of black smoke overflow, realize the process of melting light and thin aluminum waste materials without open fire, greatly reduce the oxidation and burning loss of aluminum waste materials, and improve the yield of aluminum waste. Therefore, for customers with light and thin crushing waste aluminum raw materials and customers with iron waste aluminum raw materials, most of them adopt the process route of twin chamber aluminum melting furnace immersion melting technology. The twin chamber aluminum melting furnace is characterized by low oxidation burning loss, high aluminum water recovery rate, pure aluminum water, less slag production, good environmental protection effect, high melting efficiency, low energy consumption, and high production efficiency. It is currently recognized as one of the most mature technologies for online recovery of aluminum chips and scrap with iron in the world.
