What is the production process of industrial aluminum profiles?

Industrial aluminum profiles refer to all aluminum profiles except those used in the construction of doors and Windows, curtain walls, indoor and outdoor decoration and construction structures. Industrial aluminum profile is a kind of aluminum as an important component of the alloy data, aluminum rod through hot melt, extrusion to obtain different sectional shape of aluminum data, assembled into products, according to different load-bearing profiles of different specifications, and take supporting aluminum profile accessories, do not need to weld, more environmentally friendly, and device, disassembly, light and easy to carry, moving is very convenient. What is the industrial aluminum profile production process?
1, casting is the first process of aluminum production
Important processes are:
(1) Ingredients: According to the specific alloy grade that needs to be produced, calculate the increase of various alloy components, and reasonably match various original materials.
(2) Smelting: the prepared original data is added to the melting furnace according to the process requirements, and the impurities and gases in the melt are effectively removed by degassing and slagging refining. Industrial aluminum according to the field of application, industrial aluminum profiles refer to all aluminum profiles except for building doors and Windows, curtain walls, indoor and outdoor decoration and building structures.
(3) Casting: Under the premise of a certain casting process, the melted liquid aluminum is cooled into various specifications of round casting rods through the deep well casting system.
2, extrusion: extrusion is the means of profile forming. Industrial aluminum according to the field of application, industrial aluminum profiles refer to all aluminum profiles except for building doors and Windows, curtain walls, indoor and outdoor decoration and building structures. Firstly, according to the section of the profile product, the mold is designed and manufactured, and the heated round casting rod is extruded from the mold by the industrial aluminum extrusion machine. The commonly used grade 6063 alloy also uses an air-cooled quenching process during extrusion and a subsequent manual aging process to achieve heat treatment strengthening. Different grades of heat-treatable strengthened alloys have different heat treatment regimes.
3, color (here is the first important oxidation process)
Oxidation: The extruded aluminum alloy profile, its nominal corrosion resistance is not strong, must be nominal treatment through anodizing to increase the corrosion resistance, wear resistance and nominal beauty of aluminum.
Its important processes are:
(1) Nominal pretreatment: The name of the profile is washed by chemical or physical methods to expose the dirty matrix in order to facilitate the complete and dense artificial oxide film. Specular or matte (matte) names may also be obtained by mechanical means.
(2) Anodizing: After nominal pretreatment of profiles, under a certain process premise, the matrix nominally produces anodizing, generating a dense, porous, strong adsorption AL203 film layer. Industrial aluminum according to the field of application, industrial aluminum profiles refer to all aluminum profiles except for building doors and Windows, curtain walls, indoor and outdoor decoration and building structures.
(3) Sealing hole: the membrane pores of the porous oxide film generated after anodic oxidation are closed, so that the oxidation film's anti-contamination, corrosion resistance and wear resistance are strengthened. The oxide film is colorless and transparent, using the strong adsorption property of the oxide film before sealing the hole, adsorbing and depositing some metal salts in the film hole, which can make the profile name show many colors other than the substance (silver white), such as: black, bronze, gold and stainless steel color.
