The design of the processing tank and rotor achieves the highest level of processing efficiency.
The mechanism for degassing aluminum alloys by blowing inert gas into the molten metal involves the diffusion of hydrogen gas in the melt into the inert gas bubbles, which are then removed by floating to the surface. This is based on Sieverts' law, which shows the relationship between the partial pressure of hydrogen gas in the atmosphere and the solubility of hydrogen in the molten metal. Additionally, particles of non-metallic inclusions suspended in the molten metal are captured by a large number of fine inert gas bubbles and removed by floating. The following four points are important for the removal of gas and non-metallic inclusions: 1. Reduce the bubble size. 2. Increase the number (density) of bubbles. 3. Efficiently contact the bubbles with the molten metal in a short time. 4. Avoid generating turbulence on the surface of the molten metal.
