How South Africa’s aluminum casting machine uses advanced molten metal rotary degassing rotors to reduce costs and improve metal quality. In order to protect its position in the global automotive industry, South Africa’s aluminum casters must meet or even exceed the more demanding technical specifications to obtain better quality and cleaner metals. Technologies that can […]
The main function of the on-line degassing system is to remove hydrogen dissolved in molten metal, and the secondary function is to remove alkali metals and inclusions. The selection of on-line degassing equipment is related to the functionality of the final casting product. According to the humidity conditions in the ambient atmosphere, the on-line degassing […]
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 […]
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 […]
