Online Metal Degassing Systems can effectively remove the hydrogen content in aluminum alloy, and can ensure that the cast-rolled billet used to produce ultra-thin aluminum foil meets the quality requirements. The quality of the purified cast-rolled billet of the aluminum melt determines whether the 0.005mm aluminum foil can be rolled and the number of pinholes […]
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 […]
There are many different types of degassers, but most aluminum foundries rely on rotating rotor degasser. The rotor injects chemically active reactants (usually chlorine or solid salt flux) mixed with a carrier gas (such as argon or nitrogen) into fine bubbles and enters the molten metal. The key to operating such equipment for optimal efficiency […]
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 […]
Nitrogen degassing aluminium is used for gas blowing refining, it has the characteristics of convenient operation, environmental protection and safety, and low cost, but the refining effect is restricted by the purity of the inert gas itself. Generally, inert gases will always contain a certain amount of moisture and oxygen even if strict purification measures […]
Rotary Degassing Unit is used to complete degassing operation. Inert gas is introduced to produce efficient small bubbles. Short processing time and reduced gas use can save a lot of cost. The degassing treatment of the melt causes the injector immersed in the melt to rotate so that the scavenging gas (usually inert gas) is […]
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 […]
