Optimization Control and Homogenization Annealing Process of Processing Chemical Composition of Aluminum Parts
May 18, 2018

Aluminum component processing can effectively improve its material yield and production efficiency in the process of operation. In the process of production, it needs to formulate its scientific and reasonable production process, so that it can effectively improve its employees to some extent. The level of technical theory needs to be constantly summed up during production.

During the processing of aluminum parts, the mold design is very advanced and reasonable. During the production process, it is necessary to effectively strengthen the management of the mold, so that it can effectively improve the qualification rate of the machine in a certain degree. To a certain extent, the quality of the ingot is improved, and homogenization or homogenization is performed. Advanced technology, such as long-ingot hot-shear technology and CADEX, are used in the process.

Optimum Control of Processing Chemical Composition of Aluminum Parts

To a certain extent, architectural aluminum profiles must have certain mechanical properties. When other conditions are the same during the operation, the tensile strength and yield strength increase as the content increases. The strengthening phase of the entire product is mainly the Mg2Si phase. The Mg2Si phase is composed of two magnesium atoms and one silicon atom. The relative atomic mass of magnesium is 24.3 l, and the relative atomic mass of silicon is 28.09. Therefore, in the Mg2Si compound, magnesium silicon is The mass ratio is 1.73:1.

In the processing of aluminum parts, the magnesium is generally controlled to be about 0.5%, and the total amount of Mg2Si is controlled to 0.79%. During the process of using, when the excess silicon is 0.01%, the mechanical property of the alloy is about 218Mpa. It greatly exceeds the national standard performance, and the excess silicon is increased from 0.01% to 0.13%, and the σb can be increased to 250Mpa, which is an increase of 14.6%.

To form a certain amount of Mg2Si, it is necessary to first consider the loss of silicon due to impurities such as Fe and Mn, that is, to ensure that there is a certain amount of excess silicon. Therefore, the composition of the 6063 alloy is generally controlled to: Mg: 0.45% -0.65%; Si: 0.35% -0.50%; Mg: Si = 1.25 - 1.30; impurity Fe controlled at <0.10% -0.25%; Mn <0.10%.

Optimization of aluminum component processing for uniform annealing of aluminum alloy ingots

In the processing of aluminum parts, the homogenization of the alloy can effectively increase the extrusion speed to a certain extent, and the extrusion force can be reduced by approximately 6% when the ingot is processed uniformly at the same time when used. -10%. After the homogenization treatment, the cooling rate has an important influence on the precipitation behavior of the tissue. For the ingot after rapid cooling, the Mg2Si is almost completely dissolved in the matrix, and excess Si is also dissolved in solid solution or dispersed as fine particles. Such ingots can be extruded rapidly at lower temperatures and achieve excellent mechanical properties and surface brightness.
