Production process for effectively improving conductivity of aluminum alloy

Abstract

The invention provides a production process for effectively improving the conductivity of an aluminum alloy, relates to the technical field of aluminum alloy production, and solves the technical problem that a high-conductivity aluminum alloy conductor rail profile is difficult to produce under the condition that the mechanical property of the profile is not reduced at present. The production process for effectively improving the conductivity of the aluminum alloy comprises the steps of S1, casting, S2, extrusion and S3, aging treatment. The surface of the aluminum alloy conductor rail profileproduced through the process is free of cracks, layering, corrosion, oxide inclusions, bubbles and peeling, the elongation is good, under the condition that the mechanical property is not reduced, the electrical conductivity IACS of the profile is improved to 57% or above, and the aluminum alloy conductor rail profile has important significance in popularization and rapid development of magnetically levitated trains.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy production, in particular to a production process for effectively improving the conductivity of aluminum alloys. Background technique [0002] With the rapid development of the national economy, the continuous improvement of people's living standards, and the rapid development of urban rail transit, all large and medium-sized cities in China are vigorously developing high-speed ground transportation systems. As a safe, fast and comfortable "green vehicle", with the continuous strengthening of the awareness of the earth's environmental protection on which human beings depend at home and abroad, the maglev train will surely be continuously popularized and developed rapidly. Therefore, the market demand for conductor rail profiles will increase substantially, and the market potential is quite huge. [0003] The material used for the aluminum rail body is 6101B-T6. The 6101B alloy metal Al-Mg-...
