The aluminium degassing system can process metal, is installed on the line between the holding furnace and the casting machine. Online degassing devices have many advantages. The use of the online degassing device for continuous processing of molten metal, thereby improving manufacturing capacity. The online degassing process fully removes hydrogen and other non-metal impurities, while reducing harmful emissions and scum.<\/p>\n

\u0627\u0644\u0640 rotary degasser<\/a> is characterized by continuous flow and fully mixed series reactors. Hydrogen removal is the result of diffusion and mass transfer between the gas phase and the metal phase. The main rate control step of the degassing process is the diffusion of hydrogen through the liquid metal phase. The rotating gas jet vigorously agitates the melt, causing the metal particles to fluidize, causing non-small particles to aggregate into large particles to form the surface of the melt. The impurities floating out of the metal leave the system together with the dross.<\/p>\n

\"Rotary<\/p>\n

\u0627\u0644\u0640 online aluminum degassing system<\/a> has two functions: heating and processing. Heating is to preheat the container before filling the molten aluminum by a heater installed on the lid of the container to maintain the metal temperature in the casting interval and increase the temperature during the casting process.<\/p>\n

Molten metal aluminium \u0646\u0638\u0627\u0645 \u0625\u0632\u0627\u0644\u0629 \u0627\u0644\u063a\u0627\u0632\u0627\u062a<\/a> is to remove a certain amount of impurities (hydrogen, slag inclusion) in molten aluminum. The treatment process adopted by the device is based on the principle of gas flotation. The rotor injects and uniformly disperses inert gas, and tiny bubbles flow up into the melt. Hydrogen is absorbed into the bubbles and eliminated, the slag inclusions are captured by the bubbles, the larger slag inclusions collide with the bubbles, and the smaller slag inclusions are captured by the radial cross-section of the bubble, and then the slag inclusions rise to the surface of the melt with the bubbles to form dross.<\/p>","protected":false},"excerpt":{"rendered":"
