Technical Parameters of Aluminum Melting Furnace

Technical Parameters of Aluminum Melting Furnace

1. Energy consumption ≤ 650,000 kcal/ton aluminum.

2. Furnace specifications are: 1.5T, 2T, 3T, 4T, 5T, 6T, 8T, 10T, 12T, 15T, 18T, 20T, 25T. Special designs can be made according to user requirements. 3. Aluminum loss index ≤1.2%.

Explanation: The main economic and technical indicators: refers to the rated capacity of each furnace, the return material does not exceed 30% (clean material), and the rest are aluminum ingots. When the furnace enters the thermal equilibrium state and under normal production conditions, it reaches 740 from the feeding to the molten aluminum. The index reached during the ℃ process.

Structure and characteristics of aluminum melting furnace:

1. Adopting round bottom furnace and reasonable burner configuration, the furnace gas circulation is strong, the furnace temperature is uniform, there is no local overheating and overburning, which improves the product quality and prolongs the service life of the furnace.

2. Using shaft furnace: the charge fully absorbs the waste heat of the flue gas in the shaft furnace, reduces the temperature of flue gas at the top of the furnace, and greatly improves the thermal efficiency. When the charge enters the bottom furnace, it has been preheated to close to the melting state, ensuring a high melting rate and Very low energy consumption.

3. Adopt air preheater and furnace shell interlayer air duct: The air preheater absorbs the flue gas waste heat well, and the preheated air enters the furnace shell interlayer air duct to further preheat and increase the temperature, relatively increase the ambient temperature, and reduce the furnace. Shell heat dissipation, air preheating can improve combustion efficiency, combustion intensity, flame temperature and speed, and strengthen furnace gas circulation and heating speed.

4. The furnace door structure is reasonable and sealed, and the furnace door does not need to be added; the furnace door is tightly sealed, the opening time is short, the heat loss in the furnace is small, there is no dead corner of slagging refining, convenient operation, and good operating environment.

5. Furnace top feeding: convenient feeding, low labor intensity, small furnace temperature fluctuation, long furnace age, and feeding does not take up melting time.

6. The use of high-efficiency and energy-saving burners as the heat source has the characteristics of easy ignition, fast heating, high injection rate, safe combustion, and small excess air coefficient.
