Problems solved by technology

[0020] The conductivity of aluminum is sensitive to changes in composition and temperature. Alloying elements reduce the conductivity of aluminum, and the solid solution state is more obvious. Strengthening solid solution is the basic requirement to meet the mechanical properties of materials, and strengthening solid solution reduces the conductivity of materials, which will make The conductivity cannot meet the technical requirements

Embodiment Construction

[0026] In the production method of the aluminum alloy conductive rail of the present invention, in the production process of the aluminum alloy, the optimized internal control components and standard components of other metal elements are shown in Table 3.

[0027] Table 3 Standard alloy composition and optimized internal control composition

[0028]

[0029] In industrial production, the conventional aging system of 6101-T6 is 175℃×(6-8) hours, the conventional aging system of 6063-T6 is 175℃×8 hours or 185℃×2 hours and 205℃×1 hour, 175℃ × 8 hours is generally suitable for industrial materials, 185 ° C × 2 hours and 205 ° C × 1 hour are used for some architectural profiles.

[0030] No matter for 6061 alloy or 6063 alloy, the artificial aging process of 175℃×8 hours can achieve good results when the performance requirements are normal and the conductivity requirements are normal (≤31MS / M). In actual production, BJ and NJ conductor rails , is to adopt the aging process, bu...

Abstract

The invention discloses a production method of an aluminum alloy conductor rail, relates to a conductor rail for the power supply of a subway line, and aims to provide a production method of an aluminum alloy conductor rail with high strength and high conductivity. The conductor rail is made of aluminum alloy. During the preparation phase of the aluminum alloy, other metal elements in percentage by mass are as follows: 0.34% to 0.5% of Si, 0.12% to 0.25% of Fe, 0.02% to 0.08% of Cu, 0.02% of Mn, 0.5% to 0.65% of Mg, 0.02% of Cr, 0.03% to 0.08% of Zn and 0.01% to 0.03% of Ti.

Description

technical field [0001] The invention relates to a production method of a rail transit component, in particular to a production method of an aluminum alloy conductive rail for power supply of a subway line. Background technique [0002] With its convenience, speed, large capacity, energy saving and environmental protection, the subway is playing an increasingly important role in alleviating the pressure on ground traffic in big cities, alleviating traffic congestion, and protecting the environment. Since my country entered into the construction of subways in major central cities during the Eleventh Five-Year Plan period, it has been developing rapidly at a relatively fast pace. While the railway construction is in progress, the construction of related facilities such as power supply lines, communication lines, signal and automatic control lines must be carried out simultaneously. The conductive rail is the main material of the power supply line, and its installation, connect...
