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 […]
Refining agent degassing is currently the most commonly used method in aluminum plants to eliminate pinholes in aluminum alloy castings. In order not to cause a large amount of splashing of the aluminum liquid, the degassing agent can be added in batches, and the degassing ends the slag removal. When aluminum alloy is smelted, it […]
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 […]
Flux Refining Operation is necessary for improving the effect of refining, slagging and degassing, the following items should be paid attention to in flux refining operation. Flux Refining Operation There are many metal flux manufacturers to choose the appropriate refining agent, and there are also many varieties of metal fluxes. You can choose a suitable […]
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 […]
Aluminum alloy smelting is one of the most important process links for the production of high-quality casting rods. Flux refining process for aluminum is an important process in aluminum alloy smelting. The main components of fluxes currently on the market are chlorides and fluorides. If the process is not properly controlled, slag, pores, coarse grains, […]
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 […]
