How to control the quality of industrial aluminum in processing

Although the processing and production process of industrial aluminum profile is not very complicated, each link is very important. Because one of the links is wrong, the industrial aluminum profile produced is substandard and unqualified, so we need to pay attention to it all the time. Each process flow. Most industrial aluminum profile production abortions include the three processes of melting, extrusion and oxidation:      1. Casting: Casting is the first process of aluminum production. The main process is: three steps of batching, smelting, and casting. Ingredients: According to the specific alloy grades to be produced, the amount of addition of various alloy components is calculated and various raw materials are reasonably matched. Smelting: The prepared raw materials are added to the melting furnace according to the process requirements to melt, and the slag and gas in the melt are effectively removed by degassing and slagging refining methods. Casting: Under certain casting process conditions, the molten aluminum is cooled and casted into round casting rods of various specifications through the deep well casting system. 2. Extrusion: Extrusion is a means of forming aluminum profiles. First, design and manufacture a mold according to the profile product section, and use an aluminum extruder to extrude the heated round cast rod from the mold. The commonly used aluminum material, 6063 alloy, also uses an air-cooling quenching process and subsequent artificial aging process during extrusion to complete the heat treatment strengthening. Different grades of heat-treatable and strengthened alloys have different heat treatment systems. After strengthening, the W-20 Webster hardness tester can be used for hardness test. 3. Oxidation: The surface of the extruded aluminum alloy profile is not strong in corrosion resistance. It must be surface treated by anodizing to increase the corrosion resistance, wear resistance and appearance of the aluminum. The main process includes 3: 1) Surface pretreatment: Use chemical or physical methods to clean the surface of the profile to expose the pure matrix, in order to obtain a complete and dense artificial oxide film. It is also possible to obtain a mirror or matte (matt) surface by mechanical means. 2) Anodizing: The surface pretreatment of the profile, under certain process conditions, the surface of the substrate will be anodized to form a dense, porous, and strong adsorption AL203 film. 3) Sealing: The pores of the porous oxide film formed after anodization are closed to enhance the anti-pollution, corrosion resistance and wear resistance of the oxide film. The oxide film is colorless and transparent. Using the strong adsorption of the oxide film before sealing, some metal salts can be adsorbed and deposited in the film pores, which can make the appearance of the profile show many colors other than the natural color (silver white), such as: black, bronze, Golden yellow and stainless steel color, etc. Finally, manufacturers of aluminum profile processing need to monitor and control the above processes at all times. In industrial aluminum processing and production, attention must be paid to avoid errors. The final product cannot meet customer requirements, resulting in unnecessary losses and increased production costs. , It may also affect further cooperation with customers and affect the company’s impression of customers. ————The article comes from the Internet.
