Operating principle
The gas fired magnesium crucible furnace is equipment used for the melting and holding of magnesium ingots in a crucible that is directly heated with natural gas burners.
Crucible furnace structure
- External structure
· Barrel casing made of 4mm thick steel plate
· Crucible cover made of 25mm thick steel plate
· Bottom plate made of 8mm thick steel plate
· Cover made of 10mm thick steel plate
· Chimney made of 6mm thick steel plate, can be flipped 90 degrees - Construction materials of furnace lining
· Three layers of high temperature insulation boards (Morgan-imported)
· Insulated cotton with the density of 260
· High-purity high-temperature insulating brick: mullite (Morgan-imported);
· Specially developed insulation materials.

- Three-phase meter (1:40) (Shanghai Kirtun)
- Circuit breaker and other electrical components
- Transformer (CHINT)
- Cooling Fan
- Cooling module
- Thyristor trigger (Xiamen Yudian)
Characteristics of magnesium alloy
- The specific gravity of magnesium alloy is 2/3 that of aluminum and 2/9 that of iron, so it is very light.
- The melting point of magnesium alloy is almost the same as that of aluminum, and the boiling point is relatively low at 420 °C.
- A large amount of magnesium powder reacting violently with water will result in ignition, and the high temperature magnesium will react with the oxygen in the air to cause combustion.
