Problems solved by technology

The disadvantage is that multi-pass stretching is required to obtain products that meet the size requirements, the steps are complicated and the production cost is high
This not only increases the process and production cost, but also makes the surface of the billet seriously oxidized
In addition, in the case of horizontal continuous casting-continuous drawing, the drawn wire billet is basically a casting structure with relatively poor plasticity, and broken wires are prone to occur in the subsequent drawing process

Embodiment Construction

[0016] The embodiment uses 99.7% aluminum ingots, magnesium ingots, and Al-Si, Al-Fe master alloys, according to the chemical composition of aluminum alloy wires, after melting, the chemical composition of the melt samples is analyzed by direct spectral reading method. The actual measured composition is shown in Table 1, where Alloy 1 corresponds to LHA1 and Alloy 2 corresponds to LHA2. A horizontal continuous casting machine with a crystallizer is used to cast a round wire billet with a certain diameter. After the round wire billet is cleaned, it is extruded on an LJ300 aluminum continuous extrusion machine to form a product with a certain diameter. Die mouth products are directly quenched in water online and then coiled by online small cold deformation stretching and winding, and then artificial aging treatment is carried out in a 90KW box-type resistance furnace. The aluminum alloy composition, pouring temperature, horizontal continuous casting speed, continuous Extrusion t...

Abstract

The invention provides a process for producing an aluminum alloy conductor, comprising the following steps: proportioning materials, melting, refining, carrying out horizontal continuous casting, cleaning, extruding continuously, quenching on line, carrying out small cold deformation stretching on line and ageing manually. By carrying out small cold deformation stretching on line and ageing manually according to the characteristics of continuous extrusion and large shearing deformation, the conduction with small textures, uniform properties and excellent surface quality is obtained. The process has the advantages of simple steps, convenience of operation, high yield and low production cost. The product produced by adopting the process has uniform properties and excellent surface quality. The process provided by the invention is used for producing the aluminum alloy conductor.

Description

technical field [0001] The invention belongs to the technical field of metal plastic processing, and in particular relates to a production process of an aluminum alloy wire. Background technique [0002] Aluminum-magnesium-silicon alloy is a deformable heat-treated aluminum alloy, which has a combination of high strength and electrical conductivity, and is widely used as an aluminum alloy overhead wire. Continuous casting and rolling-multi-pass drawing process is the main method for producing aluminum and soft aluminum alloy wire blanks in the wire and cable industry. billet) → continuous hot rolling (13 passes) → wire billet about Ф9.8mm. The equipment investment of this process route is moderate, the product list is large, the finished product rate is high (over 90%), and the quality is relatively stable. The disadvantage is that multi-pass stretching is required to obtain products that meet the size requirements, and the steps are complicated and the production cost is ...
