Inert gas such as nitrogen or argon is blown into the online degassing box of aluminum alloy to turn the aluminum liquid over, the impurities rise, and the dehydrogenation can be greatly improved, which can improve the quality of aluminum alloy. On-line degassing box refining technology, full coverage of bubbles, small but many. Rolling up and down, uniform molten aluminum temperature, greatly improved alloy performance, and achieved good economic benefits.
AdTech on-line degassing equipment has a long-life furnace body using a new type of high-silicon molten material manufacturing technology. The degassing rotor, heater protection sleeve, and thermocouple protection sleeve are all made of silicon nitride ceramic manufacturing technology. And the use cost is low, the life is long, and the maintenance is simple.
The degassing efficiency is stable at an average of 60%. When the Mg in the molten aluminum working with argon is less than 1%, the best degassing effect can reach 0.09cc/100g.
The inner lining is made of high-silicon melting material. The average life of the inner cavity is 2 years, up to 3 years. The effect of non-sticking aluminum is good, and it does not pollute the aluminum melt. The internal design has a baffle plate to ensure the stability of the aluminum melt surface It can prevent air and oxides on the surface of the aluminum melt from being rolled into the aluminum melt, and bubbles or residues from flowing out.
Good thermal shock resistance, resistance to rapid cold and rapid heat. The coefficient of thermal expansion is small, and it can be used continuously at working temperature to maintain a stable appearance without deformation. No deformation or cracking occurs at a continuous baking temperature of 1050°C.
Good surface strength, resistance to liquid aluminum erosion, corrosion, no moisture absorption, no cracking, and no aeration to liquid aluminum.
Non-wetting performance with aluminum, the aluminum liquid flows through non-stick aluminum, easy to clean.
Good chemical stability, does not react with aluminum water at working temperature.
The top cover is equipped with automatic heating, which can ensure no temperature drop within 24 hours. It can realize automatic heating and temperature control functions. The heating system can freely set the temperature and display the actual temperature in real-time, automatic heating, automatic temperature control, and easy replacement of heating elements. The heating system can meet the requirements of the casting process.
The sealing structure of the online degassing equipment is designed to fully seal the box cover, the box body, and the aluminum melt inlet and outlet, which effectively prevents the slagging caused by the secondary oxidation of the aluminum melt and effectively improves the degassing effect.
