Double chamber aluminium melting furnace

The double-chamber furnace has a partition wall cast in the middle of the traditional single-chamber furnace, and channels are set up and down the partition wall to connect the furnace gas and aluminum water of the two furnaces. The middle partition divides the aluminum furnace into two chambers, which are used as the heating chamber and the feeding chamber respectively. The heating chamber is responsible for quickly increasing the temperature of the aluminum liquid, and the feeding chamber is responsible for feeding molten scrap aluminum raw materials.

Descriptions

The traditional aluminum smelting furnace has a single-chamber structure, and the feeding, heating and melting of scrap aluminum are collected 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 light and thin broken scrap aluminum materials with large specific surface areas. The oxidation burning loss rate of traditional single-chamber aluminum melting furnaces is as high as 20% without compensation.

The double-chamber furnace has a partition wall cast in the middle of the traditional single-chamber furnace, and channels are set up and down the partition wall to connect the furnace gas and aluminum water of the two furnaces. The middle partition divides the aluminum furnace into two chambers, which are used as the heating chamber and the feeding chamber respectively. The heating chamber is responsible for quickly increasing the temperature of the aluminum liquid, and the feeding chamber is responsible for feeding molten scrap aluminum raw materials.

The two furnace functions of a double-chamber aluminum melting furnace are interchangeable. While one furnace is feeding, the other is burning to melt and raise the temperature. The afterglow of the flame can be connected to the adjacent molten pool to burn organic combustibles in the light aluminum scrap, greatly reducing the impact of black smoke feeding on the surrounding environment. When the temperature of the aluminum liquid in the furnace rises to 720°C, the fire can be stopped, and the light and thin scrap aluminum raw materials and scrap aluminum raw materials are combined with the iron. Use a forklift to compress the raw materials and bury them in the aluminum liquid to form molten low-temperature aluminum, and then re- Ignition raises the temperature. The two furnaces of the double-chamber aluminum smelting furnace operate in coordination with each other. The two molten pools are continuously fed at staggered times, and the two combustion systems are continuously ignited at staggered times. 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 scrap with no name, greatly reduce the oxidation and burning loss of aluminum scrap, and improve the yield of scrap aluminum, so it is suitable for light and thin crushing Customers of scrap aluminum raw materials and iron scrap aluminum raw materials mostly adopt the process route of double-chamber aluminum melting furnace immersion smelting technology. The double-chamber aluminum melting furnace is characterized by low oxidation and burning loss and high recovery rate of aluminum water.
