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.
