Optimization of Industrial Aluminum Extrusion Process-WJW Aluminum Supplier Aluminum

Optimization of aluminum squeezing process is important from the following aspects: such as the control of chemical ingredients, optimization of uniform annealing process, optimization of squeezing heat treatment process, and so on.

1 Optimization of chemical ingredients, holding 6063-T5 construction industry aluminum must have a certain mechanical function. At the same time as the rest of the premise, its tensile strength and subsequent intensity increased with the content increase. The important phase of the 6063 gold is the MG2Si phase. How much is the amount of MG, Si and MG2Si? The MG2Si phase consists of 2 magnesium atoms and one silicon atom. The absolute atomic quality of magnesium is 24.3L, and the absolute atomic quality of silicon is 28.09. Therefore, the quality ratio of magnesium silicon is 1.73 in the MG2SI compounds: 1. 2 Optimizing the uniformly invitation process of ingot. When the production of civil squeezing profiles, the high temperature uniformity of 6063 alloy is: 560 20 C, 4-6h in preservation, and the cooling method is forced wind and cold or spray water rapid cold. The uniformity treatment of the alloy can improve the squeezing speed. Compared with the ingots that are not uniformly treated, the squeezing pressure can fall by 6 % -10 %. The cooling speed after uniformization has an important impact on the output action of the organization. For the fast -colding ingot that is cooled after the average heat, the MG2Si can be solidly soluble in the matrix, and the excess SI will also be solid soluble or the small texture that is scattered. Such a ingot may be squeezed quickly at a lower temperature and obtained the excellent mechanical function and the nominal light brightness. 3 Optimize squeezing and thermal treatment process 3.1 The heating of ingots is the most basic and most important process factors for squeezing production. The squeezing temperature has a great impact on product morality, production effect, mold life, energy consumption, etc. The most important problem for squeezing is the control of metal temperature. From the beginning of the ingots from the beginning of the ingot to the extract of the squeezing profile, the soluble phase tissue must not be referred to or showing the diffuse of small particles from the solid solution. 3.2 Squeeze speed squeezing process must be carefully controlled by the squeezing speed. The squeezing speed has an important impact on deformation thermal effects, deformation uniformity, re -crystallization and solid solution process, product mechanics functions and nominal quality of the product. The squeezing speed is too fast, and the name of the product will show numbness, cracks, etc. At the same time, the squeezing speed is too fast to increase the unevenness of metal deformation. The outflow speed when squeezing depends on the amount, size, size, and nominal condition of the alloy varieties and profiles. 3.3 Quenching on the machine 6063-T5 quenching is to cooled to the room temperature after the MG2SI out of the MG2SI in the metal metal at high temperature. The cooling speed is often proportional to the reinforcement content. 6063 The minimum cooling speed that can be strengthened by alloy is 38 C/min, so it is suitable for wind and cold quenching. Change the wind turbine and the number of fans may change the cooling intensity, so that the temperature of the product is below 60 C. 3.4 After the tension is corrected from the mold hole, the individual traction machine is trapped. When the traction machine is working, it is squeezed by a certain traction tension, and at the same time, it moves synchronously with the speed of the product outflow. The goal of using the traction machine is to reduce the wrongdoing and injury when the multi -line squeezing, and at the same time, it can also avoid twisting and twisting after the molded holes are used to cause trouble. In addition to the possibility of eliminating the longitudinal appearance of the product, it may also reduce its residual stress, the characteristics of progressive strength and adhere to its good name. 3.5 Artificial timeliness The time processing requests is uniform, and the temperature difference does not exceed 3-5 . 6063 The artificial time temperature of alloy is 200 C. Extracting insulation time is 1-2 hours. In order to improve the mechanical function, there are also 180-190 C time efficiency for 3-4 hours, but at this time the production effect will fall. 3.6 Optimization of the length of the ingot and the calculation method of the calculation of the calculation ingots is the volume method and the quality method. Through the tree -breaking mathematics association, the best ingot specifications are easily selected, and the amount of product rates of greatly improving the profile.
