Heating and Melting Equipment

Gas fired magnesium melting furnace

A3 steel plate and profile steel is used for the casing of the furnace.
The insulation layer is composed of high-quality Nano-plate, insulation material and calcium silicate board, which are laid in the outer enclosure.
The furnace lining is made from heat-resistant insulation brick.
German KromSchroder burner.
Liquid leakage alarm with an electrode connected to the alarm system of the electric furnace control cabinet. Furnace will shut down if the alarm is triggered.
The protective-gas system should be turned on until the temperature of the molten magnesium drops below 350 degrees. The crucible should not be lifted out for maintenance until the molten magnesium is cooled to a solid state naturally.
The height of the furnace can be customized according to your production needs and factory layout.

Thermal energy storage devices

6mm thick welded 304 stainless steel plate and stainless steel pipe.
Heat energy is recovered instead of exhausted into the air to heat the crucible. This saves energy by 15-20%
Effectively reduces the ambient temperature of the production plant.

Crucible

The crucible is made of bimetal composite material with a total thickness of 25mm or 31mm.
The outer layer is made of imported high-quality heat-resistant 310S stainless steel plate with a thickness of 3mm, and the inside is made of Q345R stainless steel plate with a thickness of 22mm or 28mm, to ensure the overall strength of the crucible.
The two ends of the crucible are mechanically bended forming a seamless shape, ensuring the crucible can be rotated and heated evenly.
The crucible is easy to maintain and replace if needed. Its average service life is more than 2 years.
The whole crucible is coated with boron nitride for protection.
The crucible is made of two separated chambers, a melting chamber and a holding chamber to ensure the purity of molten magnesium.
The gas is evenly distributed in the crucible.
The cover and the crucible are locked by stainless steel screws, which are resistant to high temperature, not easily deformed, and easy to disassemble. Insulation material and high temperature rope are pressed in the middle to effectively prevent air leakage.
