The bubbles are in the melt relying on the gas partial pressure difference and the principle of surface adsorption, it absorbs hydrogen in the melt, adsorbs oxidized slag, and is carried out of the melt surface as the bubbles rise, so that the melt can be purified. Because the bubbles are small and dispersed, they are uniformly mixed with the rotating melt, and then they rotate in a spiral shape to slowly float up. When in contact with the molten aluminum, it will not form a continuous linear upward air flow, which significantly improves the purification effect. The higher the purity of nitrogen or argon, the better the degassing effect.<\/p>\n<p>Rotary deaerator types and advantages and disadvantages<\/p>\n<p>\u2460External powder spraying rotary deaerator, refining and degassing is divided into two steps. The principle is that the center of the aluminum liquid surface is formed into a vortex through the rotation of the rotor, and then the automatic powder sprayer of the equipment sprays the refining agent into the vortex. The refining agent is brought into the aluminum liquid by the vortex to complete the refining and slag removal. After the refining and deslagging is completed, it enters the degassing stage again.<\/p>\n<p>\u2461Internally introduced rotary degasser, this degasser is refining and degassing at the same time. The biggest difference from the former is that the refining agent is injected through the center hole of the rotor, and the inert gas is brought into the molten metal and completed together with the inert gas. Refining and degassing of molten aluminum. This equipment will not form turbulent flow on the surface of the molten aluminum during the working period, reducing the fluctuation of the molten aluminum and avoiding secondary air suction. However, this form has higher requirements for the quality of the refining agent. If the quality of the refining agent is not good enough, it is easy to cause the air outlet to be blocked.<\/p>","protected":false},"excerpt":{"rendered":"<p>Because inclusions have a strong affinity with hydrogen, the hydrogen in the molten aluminum tends to be adsorbed in the inclusions.
