Fuel-
fired aluminum melting furnace
1. Application
Fuel-fired aluminum melting furnaces are typically used for melting for aluminum
processing industries like wire & cable, ingot casting, aluminum foil,
pressure die-casting and aluminum scraps recycling etc.
2. Fuel
Fuel-fired aluminum melting furnaces can use fuels like diesel oil, coal
tar, turpentine, heavy oil, natural gas, coal gas, LPG etc.
