Description

Heat treatment device for copper-aluminum composite wire

Technical Field

Background

The copper-aluminum composite wire is a novel material which is formed by welding a copper wire and an aluminum wire together in a cold rolling, hot rolling, explosion cladding, explosion rolling method and the like and cannot be separated.

The method is divided according to the process attributes of the common bimetal compounding process, and comprises a fusion casting compounding method, an explosion compounding method, a welding compounding method, a rolling compounding method and the like. However, when the copper-aluminum composite wire is prepared, copper and aluminum are easily oxidized in the fusion casting compounding process, so that the interface bonding strength is low, the problems of poor plate type, complex process and high cost exist in explosion compounding, welding compounding is not suitable due to the huge difference of the copper and the aluminum in the aspects of physical and chemical properties, the hot rolling compounding in rolling compounding has good bonding strength, but the size precision is low particularly in local compounding; however, cold rolling and compounding are the most potential processing method for producing local copper-aluminum composite wires on a large scale with simple operation, easy automation, precise size and high efficiency.

Therefore, in order to improve the comprehensive properties such as the interface strength and the like of the copper-aluminum composite wire, the copper-aluminum cold-rolled composite wire needs to be subjected to heat treatment. Through heat treatment, on one hand, copper and aluminum elements can be diffused mutually, and metallurgical bonding is realized at the interface, so that the bonding strength is improved; on the other hand, the residual stress in the matrix is relaxed, and the plasticity is recovered. However, during the heat treatment process of the copper-aluminum composite wire, brittle phases such as cual, cual2 and cual 4al9 are easily formed at the interface, and the brittle phases can cause the reduction of the bonding strength of the composite wire, thereby affecting the use performance of the material.

Meanwhile, when the existing composite wire heat treatment device carries out heat treatment on the composite wire, the high temperature required by processing is often directly output to the composite wire, the suddenly changed temperature can cause certain damage to the composite wire, more brittle phases are generated, the bonding strength of the composite wire is reduced, and further the processing quality cannot reach the expectation, so that the heat treatment device for the copper-aluminum composite wire is necessary to provide, and the effect of improving the processing quality can be achieved.
