2500 kg/H Continuous Gas Fired Industrial Aluminum Melting Furnace , Aluminum Scrap Melting Furnace
1. General Introduction
The gas fired aluminum melting furnace is a continous type, and has both the holding chamber and the melting chamber.
It has a compact structure for both melting and heat preservation function. The melting pool is formed by once-forming non-stick
aluminum casting material, which has the feature of high strength, easy to cleaning and long service life. The gas fired melting
furnace employs famous burner brand, which has automatic ignition, temperature control and over temperature alarm devices.

4. Gas Consumption of aluminum melting furnace
Gas consumption:
1) less than 65N3/ton aluminum (following conditions should be met:the content of scrap in the returned
material is less than 5%, especially when there is no scrap easily oxidized; the ratio of melted material is
50% for the returned material (density 400-500kg/M3) and 50% for the ingot; the temperature of molten
aluminum liquid after melting is 750°C.)
2) Less than 58M3/ton aluminum (continuous operation, no oily and watery material, no aluminum scraps,
30% of furnace material (density 400-500kg/M3), 70% of aluminum ingot; molten aluminum liquid temperature,
based on 720℃)
3) Less than 55M3/ton aluminum (100% for ingots in continuous operation; aluminum liquid temperature after
melting based on 720°C.)
Calculation time is timed after the material is put in, and the input raw material per hour is greater than or equal
to the melting volume per hour. When the aluminum liquid temperature in the aluminum metal melting furnace
is reached and the aluminum liquid is
discharged, the water output reaches the melting efficiency specified by the equipment, and the minimum 3
hours is a statistical cycle, take the average value as the unit energy consumption standard.
