Problems solved by technology

In the traditional forming process, the processing technology is generally to heat-melt and extrude aluminum rods to obtain aluminum alloy profiles with different cross-sectional shapes. This traditional process method has the problem of poor forming stability of aluminum profiles. The internal structure of aluminum alloy profiles is low in density, and even its surface has obvious defects, which will greatly affect its processing performance
In addition, in the case of unmodified aluminum alloy in the past, its electrical conductivity is poor, so it is not suitable for the IT industry

Abstract

The invention relates to an aluminum alloy section production process for the IT (information technology) industry. The aluminum alloy section production process includes S1, preparing aluminum for the IT industry, S2, performing hot extrusion forming, S3, quenching online, S4, stretching and straightening, S5, sawing, S6, mounting frames, S7, performing artificial aging processing, and S8, sawing and packaging finished products. The step S1 includes S101, preparing materials and S102, smelting. The extrusion equipment is a 2000T extruder, and the extrusion die is a broadening die. The step S2 includes S201, heating casting bars, S202, heating the extrusion equipment and S203, performing extrusion forming. The aluminum alloy section production process has the advantages that the 2000T extruder is adopted, the extrusion die is the broadening die, and the hot extrusion forming is performed under the condition of high temperature, so that finished aluminum alloy sections have compact internal organization and good processing performance; alloying elements such as Mg (magnesium) and Si (silicon) are added into the aluminum alloy sections, so that heat and electricity conduction performance is good; and dimensional precision is high and evenness is good, so that secondary processing is not needed.

Description

technical field [0001] The invention relates to a production process of an aluminum alloy profile, in particular to a production process of an aluminum alloy profile for the IT industry. Background technique [0002] In the industrial field, my country's industrial aluminum profiles currently account for only about 30% of the total application of aluminum profiles; while in the consumption structure of aluminum profiles in Europe, North America and Japan during the same period, the proportions of industrial consumption reached 60%, 55% and 40% respectively, far Higher than the proportion of my country's application. The difference in consumption structure reflects the lack of production, development and application of my country's aluminum profiles in the industrial field, and also indicates that my country's industrial aluminum profile consumption has huge room for growth. [0003] In the IT industry, the application of aluminum alloy profiles is particularly common due to ...
