Multi-function refining flux is an important auxiliary material in aluminum alloy smelting. At present, the main components of flux on the market are chloride and fluoride. Among them, chloride has a strong water absorption and is easily affected by moisture. Therefore, the raw materials used for flux production must be dried, water must be completely […]
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 […]
Aluminum Refining Flux should be added in proportion. The aluminum refining agent is generally 0.3% of aluminum alloy. Method Use a seamless steel pipe inserted 20cm from the bottom of the molten aluminum, and spray the refining agent with nitrogen or argon. After the refining spray, the nitrogen or argon is blown for another 15-20 […]
The surface of the aluminum material has an uneven thickness of the oxide film, sometimes also absorbs water, is mixed with sand, sticky with oil stains, and painted with paint. When melting, the aluminum material is further oxidized in a high-temperature environment, the thickness of the oxide film increases, and it reacts with moisture to […]
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 […]
In the smelting process of aluminum and aluminum alloys, hydrogen and oxidized inclusions are the main substances polluting the aluminum melt. Aluminum easily forms A1202 or sub-alumina (Al2O and A10) with oxygen. At the same time, it is also very easy to absorb gas (H) whose content accounts for 70-90% of the total gas in […]
