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 aluminum alloy liquid is refined and degassed by rotating degassing device, and the gas content of aluminum liquid is required to be less than 0.20 ml / 100 g al. After testing, the gas content in the aluminum alloy liquid is 0.16 ml / 100 g Al, which meets the technical requirements and does […]
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 […]
Purification treatment of aluminum: The surface of the aluminum material has an uneven oxide film, which sometimes absorbs moisture, is mixed with dust, oil, and is coated with paint. When melting, the aluminum material is further oxidized in a high temperature environment, and the thickness of the oxide film increases, and it reacts with the […]
Slag remover belongs to a processing flux for purifying aluminum alloy melt. It is composed of a variety of chlorides and fluorides. It has not only a remarkable slag removal effect, but also degassing and covering functions. Slag removal and degassing are the two central links and ultimate goals of aluminum alloy melt purification treatment, […]
Aluminium degassing machine most notable feature is the graphite stator and graphite rod/rotor structure. The graphite stator does not rotate in the molten aluminum and protects the graphite rod/rotor assembly. The graphite rod and the graphite rotor are assembled together to stir the aluminum water. The inert gas passes through the gap between the stator […]
Aluminum degassing units can reduce gas accumulation and problems and achieve the highest refining efficiency. Online degassing unit adopts advanced high silicon melting technology to get a long service time, degassing rotor, heater protection thimble and thermocouple protection thimble adopt ceramic manufacturing technology. Aluminum degassing units are used for hydrogen (H) and slags removal from […]
Aluminium Degassing Process: In addition to hydrogen, it is necessary to prevent moisture and various dirt from entering the crucible or furnace, but also to eliminate oxide inclusions and hydrogen in the aluminum liquid. Because only by effectively removing the dispersed inclusions suspended in the molten aluminum, can the molten aluminum be prevented from increasing […]
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 […]
