Aluminum alloy is one of the most widely used non-ferrous metal structural materials in industry, which has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, chemical industry and other industries. With the rapid development of industrial economy, the demand for aluminum alloy welded structural parts is increasing day by day, which makes the research on the weldability of aluminum alloy more in-depth. Aluminum alloy is the most widely used alloy at present. When choosing aluminum alloy, we should also consider some factors to make a choice. Now many industries begin to use aluminum profiles, so its application scope is still relatively wide. In particular, with the support of relevant markets, china industrial aluminum extrusion profile factory provides various types of products, which makes many consumers willing to use aluminum profiles to make equipment, clean shed, etc. Because the structural properties of aluminum profiles are relatively stable, they are welcomed by many consumers. In order to better understand the aluminum profile, it is necessary to popularize its production process for everyone, so that there will be no difficulty in the process of purchase. Generally speaking, the processing of aluminum profiles mainly includes three processes: melting and casting of aluminum bars, extrusion aging of profiles and surface treatment.
1. Melting and casting: This is the first process of aluminum profile production. The main process is: batching: according to the specific alloy brand to be produced, calculate the addition amount of various alloy components, and reasonably match various raw materials. Smelting: add the prepared raw materials into the smelting furnace according to the process requirements for melting, and effectively remove the impurities and gases in the melt by degassing and deslagging refining means. Casting: the molten aluminum is cooled and cast into round bars of various specifications through deep well casting system under certain casting process conditions. china industrial aluminum extrusion profile factory has been improved in the melting and casting process. The more sophisticated operation technology, improve the production quality of products.
2. Extrusion: extrusion is a means of profile forming. First, the die is designed and manufactured according to the section of the profile product, and the heated round cast bar is extruded from the die by the extruder. For 6063 alloy, an air-cooled quenching process and artificial aging process are used to complete the heat treatment and strengthening. The heat treatment system is different for different grades of heat treatable strengthening alloy.
3. Coloring: the surface corrosion resistance of the extruded aluminum alloy profile is not strong. The surface treatment must be carried out through anodizing to increase the corrosion resistance, wear resistance and appearance beauty of the aluminum alloy profile. This link is very important. Exquisite processing technology will extend the use time of profiles. Now china industrial aluminum extrusion profile factory has various processing methods, such as powder spraying, fluorocarbon spraying, anodizing, electrophoresis, etc.
The above is the whole process of aluminum profile processing. The quality of aluminum alloy profiles determines the brand level of aluminum alloy doors and windows. With the continuous upgrading of consumption, the market potential of high-end aluminum alloy doors and windows is huge. We believe that more and more excellent china industrial aluminum extrusion profile factory will produce products with higher use value. We also believe that in the near future, more and more excellent products will facilitate our life.
