Aluminum melting and holding crucible furnace

 

Usage
• Mainly used for heat preservation of molten aluminum alloys, suitable for pre-aluminum casting degassing and slag removal, alloy preparation, structure homogenization and temperature regulation.
• Energy sources include electricity and gas.

 

Equipment Features
• Higher-quality molten aluminum can be obtained. Molten aluminum temperature accuracy, composition uniformity and lower gas content can be guaranteed.
• Flexible production organization. The crucible can be replaced at any time for production of different types of alloys, without contaminating the molten aluminum.
• Low burning loss of aluminum. The aluminum in the crucible is heated with heat conduction of the crucible, without local high temperature, reducing oxidizing loss and high-temperature volatilization, lowering the burning loss of aluminum to a level below 1.2%.
• The furnace floor is molded by monolithic casting with a casting material. Moreover, at the bottom of the furnace body is a leakage outlet, through which the molten aluminum can outflow once the crucible is broken, reducing the risk of damage to the furnace body.
• The temperature of the furnace chamber and molten aluminum is controlled by series circuit, ensuring sufficient heating efficiency and preventing overheating of the furnace chamber.
• The molten aluminum thermocouple protect tube is made from silicon nitride, which is highly heat-conducting, resistant to corrosion by the molten aluminum, resistant to thermal and cold shocks and highly strong. The tube can be directly immersed in the molten aluminum to measure its temperature. It has a service life of more than 2 years.
• Multiple safety protection modes are adopted, such as molten aluminum over-temperature alarm, furnace chamber over-temperature alarm and crucible leakage alarm.

 

Electric heating aluminum melting and holding crucible furnace
• The electric heating element has a service life of more than one year.
• The heat holding layer is made of Nano-insulation slabs, with little heat stored in the furnace body.
• Melting rate in a cold furnace: ≤4.5h
• Melting rate in a heated furnace: ≤3h

 

Gas fired aluminum melting and holding crucible furnace

• Heating energy sources: natural gas, liquefied petroleum gas (LPG).
• An imported famous-brand automatic burner or gas burner is adopted, ensuring high combustion performance, low noise and zero-discharge of fume, meeting the environmental protection requirements.
• After combustion, the hot furnace gas is blown back to the upper mouth of the crucible through the flue or replaced with warm-up combustion-supporting air through the flue to improve the heating efficiency and reduce fuel consumption.
• Multiple safety protection modes are adopted, such as gas under-pressure, oxidant gas under-pressure and flame failure alarm.
• Melting rate in a cold furnace: ≤3.5h
• Melting rate in a heated furnace: ≤2h
