Problems solved by technology

As we all know, the mechanical properties of copper and aluminum are quite different. Even after multi-pass drawing with an area reduction rate of more than 80%, the copper strip and aluminum-magnesium alloy rod or pure aluminum rod cannot reach the level of metallurgical bonding.

Abstract

The invention discloses a preparation system of a copper-clad aluminum cable, which relates to the technical field of a preparation device of a metal material. The system comprises a copper-clad aluminum bar preparation furnace, a drawing machine and an annealing furnace, the preparation furnace is used for preparing a copper-clad aluminum bar, a first conveying device is arranged between the preparation furnace and the drawing machine, the cooled copper-clad aluminum bar is conveyed to the drawing machine through a first conveying device for several drawing treatments, a copper-clad aluminumwire is formed, a second conveying device is arranged between the drawing machine and the annealing furnace, and the drawn copper-clad aluminum wire is conveyed to the annealing furnace for annealingtreatment through the second conveying device. The system uses centrifugal casting of copper and directional solidification of copper and aluminum to prepare copper-clad aluminum composite bar when preparing copper-clad aluminum cables, and has the advantages of good interface bonding of aluminum and copper and high strength of aluminum and copper due to adopting directional solidification technology of copper layer-level aluminum core.

Description

technical field [0001] The invention relates to the technical field of metal material preparation devices, in particular to a copper-clad aluminum cable preparation system. Background technique [0002] Copper and copper alloys are the preferred materials for cables due to their excellent comprehensive mechanical properties and high electrical conductivity, but the price of copper is relatively high. In the process of communication signal and power transmission, the current frequency is very high, due to the "skin effect", the transmitted current is mainly transmitted through the surface of the cable. Therefore, in order to save materials, scientists have designed copper-clad aluminum composite wires, using cheaper aluminum in the core of the cable, and using copper on the surface. The density of copper clad aluminum wire is about 40% of that of pure copper wire. At present, the application of copper-clad aluminum composite layered materials in the fields of communication ...
