Heat treatment method of aluminum plate sheet

Feb 18, 2022

The aluminum plate dissipates evenly in the tempering process, and the deformation is small, which ensures the regular operation of the post-process. At this stage, water is used as a heat treatment agent in the heat treatment process of aluminum plates. Since water is not known for economic development, safety, and environmental protection, because water dissipates heat faster, the aluminum plate is easy to deform during the tempering process. When the deformation is serious, the aluminum plate will be damaged because the next process cannot be carried out. Therefore, when the heat treatment method is selected, the aluminum plate not only needs to meet the heat treatment requirements, but also the deformation needs to be adjusted within the allowable range. According to the above analysis, first of all, the ideal heat treatment method of aluminum plate is to rotate heat treatment, and at the same time realize internal and external cooling. Internal cooling and the selection of heat treatment methods for aluminum plates take into account two factors. The cooling rate of the aluminum plate in the heat treatment process can ensure the estimated heat treatment structure; secondly. The water is sprayed from the nozzle to the pipe, and the total flow of water should not be less than 10m/outside cooling can be sprayed or immersed in the heat treatment tank, but there must also be a mixing nozzle in the heat treatment tank. In general, the heat treatment of the aluminum plate should meet the requirements of the cooling function, and the cooling should be as symmetrical as possible, which is also the guideline for selecting the heat treatment method. The ideal heat treatment agent is that the cooling efficiency of the powder layer is fast, preventing the dissolution of martensite and improving the cutting performance of the steel; the cooling rate in the ultra-low temperature area is relatively slow, so as to reduce the structural stress in the process of austenite change and reduce the deformation or cracking of the aluminum plate. open. There is no ideal heat treatment agent, but these two elements should be considered when selecting a heat treatment agent.


The selection of heat treatment agent should be based on factors such as the type of aluminum plate, technical standards and steel composition. Taking petroleum pipelines as an example, the heat treatment process of (compressive strength) aluminum plate is selected by heat treatment and quenching process, that is, heat treatment high temperature quenching. The key is to use low carbon and environmentally friendly medium carbon alloy tool steel. The reasonable thickness (wall thickness) of the aluminum plate is basically the same. The pressure distribution of each part in the heat treatment process is small, and the risk of cracking is relatively low. Therefore, water can be used as a heat treatment agent. The characteristic of water is that the cooling speed is faster, which can improve the cutting performance of steel, reduce the composition of aluminum alloy, and reduce the cost of products. In addition, water as a heat treatment agent is safe and economical in production and processing. In addition, because water dissipates heat faster, the aluminum plate will undergo relatively large deformation. If the surface of the aluminum plate is defective, it will be returned to the In the fire link, it expands into defects and damages. If the carbon content in the aluminum coil is high, in order to reduce heat treatment deformation or cracking, rapid quenching oil or water-based quenching liquid with relatively slow cooling speed should be used as heat treatment agent. If the aluminum plate manufacturer needs to have stronger future development advantages in the industry, and can obtain more customers' compatibility and recognition to improve the economic benefits of the manufacturer's production, it is suggested that the manufacturer must master the following when conducting production and manufacturing. This kind of common problem, of course, can ensure the quality of processing faster. Manufacturing technology must be continuously improved and the management level and control of workers must be standardized faster. The versatility of manufacturing production equipment must be continuously strengthened and independently innovated, so it can be prevented from being replaced by this field. Gain the compatibility and recognition of more customers, and give full play to the advantages of faster manufacturing. Nowadays, the competitiveness of manufacturers is more intense, and all fields have already become increasingly fierce market competition links. Therefore, in all fields, it is necessary to continuously improve the production and manufacturing process, and it is also necessary to control the level of production and manufacturing management faster. Only in this way can the products produced and processed can be affirmed and warmly welcomed by more customers.
