There are mainly three types of aluminum melting furnace for the scrap aluminum melting process
1:Gas- Fired Aluminum Melting Furnace
2: Electric Aluminum Melting Furnace
3:Induction Aluminum Melting Furnace
The gas-fired aluminum melting furnace is usually for usually adopted in areas where gas is cheap or where electricity resources are scarce. it takes about 2.5 hours to melt one batch aluminum, and this gas-fired melting furnace can also be suitable for some low temperature metal, like, zinc, lead, copper, brass.
The electric aluminum melting furnace adopt the Resistance wire as heating element ，the melting speed is low, usually it will takes about 4 hours to melt one batch, so most client will use the electric aluminum melting furnace to work togehter with the die casting machine, which can work as melting furnace & holding furnace.
Induction aluminum melting furnace because of the charistictic of rapid melting speed and Electromagnetic stirring force， so usually will be adopted in the aluminum ingot casting foundry, usually 40-60 minutes will finish one batch melting, and becasue of the strong Electromagnetic stirring force, the Smelted molten metal is uniform，So it is ideal for the aluminum ingot casting.
