◆ Bubbles are distributed throughout the melt, increasing the contact area between the refining bubbles and the molten metal and extending the reaction time between the gas and harmful substances. This helps remove dissolved gas, slag, and impurities from the molten metal to the surface, resulting in high refining efficiency.
◆ The graphite rotor is made of high-purity graphite. Its design not only breaks up the bubbles but also ensures uniform mixing of the molten aluminum with the refining gas discharged by the rotor, increasing the contact area and contact time between the bubbles and the molten aluminum alloy and improving degassing and purification.
◆ The combined “gas + flux” purification process reduces gas and refining agent consumption and fume emissions, while improving operational safety and environmental protection.
