Rotary Degassing Aluminum works by rotating nozzle of degassing unit. The rotating nozzle has a rotating shaft, a rotor with blades (connected to the rotating shaft), and a stator with blades. Their interaction can provide the desired bubble shape for the melt. The refined gas emerges into the aluminum melt through the small gap between […]
The principle of the aluminum degassing equipment is that the rotating graphite rotor blows inert gas into the liquid aluminum. Aluminum Degassing Equipment Principle The gas (argon or nitrogen) is broken into a large number of dispersed bubbles, which are dispersed in the liquid aluminum. The bubbles in the liquid aluminum rely on the gas […]
Turbulence or agitation of the melt and increased holding temperature significantly increase the rate of hydrogen solution, oxidation, and transient element loss. The mechanical properties of aluminum alloys depend on casting soundness, which is strongly influenced by hydrogen porosity and entrained nonmetallic inclusions. The aluminum foundry needs to degas and filter inclusions by Online Degassing […]
