Problems solved by technology

Although the cold rolling composite method has been used in industrial production as early as the 1950s, it has not achieved ideal results when used in the production of copper / steel composite materials. The reason is that the matrix and oxides of copper and its alloys have good properties. During cold rolling and compounding, although the billet is cleaned by a wire brush and the deformation reaches 70% in the first pass, no cracks appear on the surface. As a result, the billet is squeezed into the crack of the steel with a thin oxide film on the original surface and steel Composite (to further increase the amount of deformation in the first pass and be limited by the capacity of the rolling mill), so the combination is very fragile, the combination strength is low and unstable

Description

[0001] technical field [0002] The invention relates to a composite layer metal composite material, in particular to a composite layer metal pipeline. [0003] Background technique [0004] As the main component of materials, metal materials play a leading role in production and application. However, the progress of science and technology has higher and higher requirements on the performance of metal materials, and a single metal material can no longer meet these needs. Moreover, in production practice, very expensive non-ferrous metals and other rare metal materials must be used in order to meet the needs of manufacturing special engineering structure performance. In order to maximize the performance of metal materials, one of the methods is to combine materials with different properties to make composite materials. [0005] Copper / steel composite materials not only have the unique properties of copper, but also have the strength and mechanical properties of steel, so a...
