High-Purity Aluminum Casting Box Type Degassing Unit - Leading China Suppliers & Factory for Enhanced Refining Efficiency
Introduction
In the aluminum melting and processing industry, product quality and production efficiency are always the core concerns of enterprises. With the increasing demand for high-quality aluminum, the purity of liquid aluminum becomes particularly important. Gases and impurities in liquid aluminum can affect product performance, resulting in production defects and waste.
As one of the most effective molten aluminum degassing technologies, the box degassing device efficiently removes gases and inclusions from liquid aluminum, making it the preferred solution for high-end aluminum castings.
In a box type degassing device, the rotor rotates at high speed in the box to disperse the inert gas to form a large number of small dispersed bubbles. These small bubbles enter the aluminum liquid, and carry away the hydrogen and oxidation slag in the aluminum liquid with the floating, to achieve the purpose of degassing and refining. During the rise of the bubble, the inclusions will be brought out of the surface of the liquid aluminum by surface tension to form scum, so as to effectively remove impurities. At the same time, the stirring of the rotor makes the alloy composition in the aluminum liquid more uniform, and further improves the quality of the aluminum liquid. Through this process, the box degassing unit significantly improves the purity and performance of the aluminum.
Product Features
Optimal gas dispersion The dispersion of process gas in liquid aluminum is excellent, ensuring full contact between bubbles and liquid aluminum.
Seal design The box is completely sealed to provide a stable inert gas environment and eliminate external influences.
Smooth liquid aluminum surface The liquid aluminum surface remains smooth to avoid turbulence and improve casting quality.
Easy maintenance The installation and maintenance is easy. The lining of the pre-fired degassing box can be changed quickly to reduce downtime.
Low operating costs The overall maintenance and operation costs are low, and the rotor and shaft have a long life to ensure the long-term stability of the equipment.
Durable The heater and its protective tube have a long service life, and the cooling gas does not require the rotor rotating spindle, reducing energy consumption.

Frequently Asked Questions (FAQ)
What is a box degassing device and how does it work?
A box degassing device is a molten aluminum refining system. Inside the sealed box, a rotor rotates at high speed to disperse inert process gas into a large number of tiny, dispersed bubbles. As these bubbles float upward through the liquid aluminum, they carry away dissolved hydrogen and oxidation slag to the surface, where they form scum and are removed.
How does the box type degassing unit improve the quality of aluminum castings?
By efficiently removing hydrogen gas and non-metallic inclusions (oxidation slag) from the liquid aluminum, the device prevents production defects and waste in the final castings. Additionally, the mechanical stirring action of the rotor ensures a more uniform alloy composition throughout the molten metal.
Is the maintenance of the pre-fired degassing box complicated?
No, the device is designed for easy maintenance. The lining of the pre-fired degassing box can be replaced quickly to minimize downtime, and the overall installation and maintenance procedures are highly simplified to ensure continuous production.
What are the core technical advantages of this degassing device?
The key advantages include optimal gas dispersion, a fully sealed box design to maintain a stable inert environment, smooth liquid surface control to prevent turbulence, low operating costs, long-lasting heaters/protective tubes, and highly durable rotors and shafts.
Which model is suitable for a production line with a flow rate of 30 T/H?
For a maximum flow rate of 30 T/H, the model HMBDU-30 is suitable. It features 2 rotors, 2 heaters, a centralized drive design, and has a maximum gas consumption capacity of 140 L/min.
