                                                      Performance and application of aluminum castings









Cast aluminum alloy has the advantages that other aluminum castings can't match, such as aesthetics, light weight and corrosion resistance, which makes it popular among users. Especially since the automobile is lightweight, cast aluminum alloy castings have been obtained in the automotive industry. A wide range of applications.
Cast aluminum alloys have a lower density than cast iron and cast steel, but have a higher specific strength. Therefore, the use of aluminum alloy castings under the same load conditions can reduce the weight of the structure, so aluminum alloy castings are widely used in the aviation industry and power machinery and transportation machinery manufacturing. Aluminum alloy has a good surface gloss and good corrosion resistance in the atmosphere and fresh water, so it has a wide range of applications in the manufacture of civilian utensils. Pure aluminum has good corrosion resistance in oxidizing acid media such as nitric acid and acetic acid, so aluminum castings have certain uses in the chemical industry. Pure aluminum and aluminum alloys have good thermal conductivity, heat exchange devices used in chemical production, and parts requiring good thermal conductivity on power machinery, such as cylinder heads and pistons of internal combustion engines, etc. Manufacturing.
Aluminum alloy has good casting properties. Since the melting point is low (the melting point of pure aluminum is 660.230C, and the casting temperature of aluminum alloy is generally about 730-750oC), casting methods such as metal type and pressure casting can be widely used to improve the intrinsic quality and dimensional accuracy of aluminum castings. Surface finish and production efficiency. Due to the large latent heat of solidification, the solidification process of aluminum liquid lasts much longer than that of cast steel and cast iron under the same weight conditions, and the fluidity is good, which is beneficial to casting thin-walled and complex castings.
Casting aluminum alloy castings has many advantages, making it the development direction of the foundry industry and one of the most favored casting products for purchasing customers. In the future, with the advancement of aluminum alloy casting technology, it will show its own on a larger stage. Style.

                Ten things that must be paid attention to in precision casting! 1. Unblock all obstacles to the channel and site. 2. Check if the ladle is dry, whether the bottom of the bag, the ear, the bag and the end are safe and reliable, and whether the rotation is flexible. Do not use dry Iron ladle. 3, all tools in contact with molten iron, must be preheated to 500 degrees Celsius before use, otherwise it should not be used. 4, the ladle should not exceed 80% of the volume, the ladle should be smooth and slow, keep the steps to prevent the overflow of molten iron. Cast iron 5, before the crane crane should check the iron of the hook, the chain is reliable, the chain is not allowed to knot, there is a person responsible for tracking the iron in the water There must be no staff on the line. 6. Strictly implement the "six will not fall": (1) The temperature of molten iron is not enough; (2) The molten iron grade is not poured; (3) does not b

                                                                   Factors affecting the surface roughness of stainless steel castings Surface roughness is another major quality indicator for stainless steel castings , generally less than 3.2 μm, between 0.8 and 3.2 μm. There are many factors affecting the surface roughness of castings, such as the pressure type, the surface quality of the investment and stainless steel, the casting process, the type of alloy and other factors. (1) Profile and investment surface quality. The surface roughness of the investment mold is the most important part affecting the surface roughness of the casting, and it is related to the surface quality of the molding, the compression molding method and the pressing process parameters. (2) Stainless steel surface quality. Stainless steel is a columnar columnar structure network, and refractory materials, additives, and water are filled in the middle, so that there are pores of different sizes on the su
