Embodiment 1

[0013] According to the proportion by weight of 4.0% magnesium, 0.2% chromium, 0.25% boron, and the balance is aluminum, the raw materials are prepared, and after smelting-primary drawing forming-heat treatment-rough drawing-middle drawing-heat treatment-fine drawing, the fine drawing is formed The wire coil enters the automatic monitoring tubular annealing process. In this process, the automatic monitoring tubular annealing equipment is used. The equipment has a pay-off machine, a tubular annealing furnace, a take-up machine and a monitoring system. In the tubular annealing furnace: vacuum is maintained in the preheating section and soaking section. When the speed is 800-1000 rpm, the temperature is controlled at 380-430°C, and low vacuum is maintained in the exit section. Low-temperature micro-oxidation is achieved, and a thin oxide film is formed on the surface of the alloy round wire, which can reduce the resistivity and increase the elongation. The upper end surface of t...

Abstract

The invention relates to a band-shape cable inner conductive aluminum magnesium alloy wire that contains aluminum magnesium alloy wire core and lithiation oxidation resistance film. The wire core is made up of Mg 3.5-4.5%, chrome 0.2-0.3%, boron 0.2-0.3%, and the rest is Al. It includes the following steps: melting, raw drawing molding, heat treatment, raw drawing, middle drawing, heat process, fine drawing to make semi-finished alloy thread and taking tubular mode annealing technology. The invention has good alloy intension, good drawing capability, good corrosion stability and conductivity. It could sharply decrease the producing cost.

Description

(1) Technical field [0001] The invention relates to an electronic communication shielding alloy wire and a production method thereof. (2) Background technology [0002] In the prior art, the electronic communication shielding alloy wire is made of copper material. Although the copper material has low resistivity and good ductility, copper materials are relatively scarce in my country and the production cost is relatively high. However, materials such as aluminum and magnesium are rich in resources in my country. Using aluminum-magnesium alloy wires as electronic communication shielding alloy wires is a good way to save production costs, but a new exploration of the composition of aluminum-magnesium alloy wires is required. The existing general aluminum-magnesium alloy wire production method is: smelting-initial drawing forming-heat treatment-rough drawing-intermediate drawing-heat treatment-fine drawing-multifilament-inspection and storage, and the aluminum-magnesium alloy w...
