As a new type of health and environmental protection industry, all-aluminum furniture has received widespread attention. All-aluminum home improvement manufacturers have said a lot about the advantages of all-aluminum home improvement, but relatively little is known about the manufacture of aluminum alloy materials. In fact, the main processes for aluminum alloy profile manufacturers to produce aluminum alloy profiles are casting, extrusion and oxidation. 1. Casting: Casting is the first process in aluminum production. The main process includes batching, smelting, casting: (1) Batching: According to the specific alloy grades produced, calculate the addition amount of various alloy components, and reasonably match various raw materials. (2) Smelting: According to the requirements of the smelting process, the prepared raw materials are added to the smelting furnace, and the method of degassing and slag removal refining is used to effectively remove impurities and gases in the melt. (3) Casting: Under certain casting process conditions, through a deep well casting system, the molten aluminum is cooled and cast into round bars of various specifications. 2. Extrusion: Extrusion is an important means of profile forming. Firstly, a mold is designed and manufactured according to the section of the profile, and the heated round cast rod is extruded from the mold by the extruder. There are also air-cooled quenching process and artificial aging process to complete the heat treatment and strengthening. Different grades of heat-treatable strengthened alloys have different heat treatment systems. 3. Oxidation: The surface of extruded aluminum alloy profile is not strong in corrosion resistance, so it must be anodized to improve the corrosion resistance, wear resistance and appearance of aluminum. Main process: (1) Surface pretreatment: clean the surface of the profile with chemical or physical methods to expose the pure matrix and obtain a complete and dense artificial oxide film. Mirror or matte (matte) surfaces can also be obtained by mechanical methods. (2) Anodizing: Under certain process conditions, the surface of the profile after surface pretreatment will undergo anodization to form a dense, porous, and strong adsorption film. (3) Sealing: Sealing the pores of the porous oxide film formed after anodization to enhance the anti-pollution, corrosion resistance and wear resistance of the oxide film. The oxide film is colorless and transparent. Utilizing the strong adsorption of the oxide film before sealing, some metal salts are adsorbed and deposited in the film pores, making the appearance of the profile showing a variety of colors other than the natural colors (silver white) such as black, bronze, golden, and stainless steel. Although all-aluminum home furnishing is a new star in the home furnishing industry, with the expansion of aluminum applications and the healthy and green advantages of aluminum alloy profiles, all-aluminum home furnishing has become an important supplement to solid wood and panel home furnishings, and has attracted more and more attention and favor from consumers.
