2021-11-05

Aluminum alloy casting is an aluminum alloy that fills molten metal in a mold to obtain parts of various shapes. It has the advantages of low density, high specific strength, good corrosion resistance and casting processability, and less restrictions on part structure design. Aluminum alloy casting can be divided into Al-Si and Al-Si-Mg-Cu-based medium-strength alloys; aluminum-copper-based high-strength alloys; aluminum-magnesium-based corrosion-resistant alloys; Al-Re-based thermal strength alloys. Most of the heat treatment is required to achieve the purpose of strengthening the alloy, eliminating the internal stress of the casting, and stabilizing the organization and size of the parts. Aluminum alloy casting is generally used to manufacture beams, gas turbine blades, pump bodies, towers, wheels

Most of the heat treatment is required to achieve the purpose of strengthening the alloy, eliminating the internal stress of the casting, and stabilizing the organization and size of the parts. Aluminum alloy casting is generally used to manufacture beams, gas turbine blades, pump bodies, towers, hubs, intake lips and engine shells. It is also used in the manufacture of automotive cylinder heads, gearboxes and pistons, instrument housings and turbocharger pump bodies.

aluminum alloy castingIt has good casting performance and can be made into parts with complex shapes; it does not require a lot of additional equipment; it has the advantages of saving metal, reducing costs, and reducing working hours, and is widely used in aviation, civil and other industries.aluminum alloy castingUsed in the manufacture of beams, gas turbine blades, pump bodies, towers, hubs, intake lips and engine casings. It is also used in the manufacture of automotive cylinder heads, gearboxes and pistons, instrument housings and turbocharger pump bodies.

Aluminum alloy casting is mainly to remove gas and non-metallic inclusions in the alloy liquid. The gas in the aluminum alloy is mainly hydrogen (accountingMore than 85%), inclusions are mainly alumina. Since the saturation solubility of hydrogen in liquid and solid aluminum alloys differs by a factor of nearly 20,aluminum alloy castingIt is easy to hydrogen evolution during solidification, resulting in pinholes in castings. Interaction of inclusions with gases.

WhenWhen the hydrogen content in 100g of industrial pure aluminum is higher than 0.1ml, pores will appear. In high purity aluminum, hydrogen is contained per 100g of aluminum alloy. Whenaluminum alloy castingVolume upAt 0.4 ml, stomata will appear. It can be seen that degassing requires slag removal, and slag removal is the basis of degassing.
