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 deformatio

Abstract

The invention relates to a production method of a copper-steel composite plate. The production method comprises the following steps of: performing surface cleaning, performing texturing treatment, spraying a binding layer, rolling and annealing, wherein before rolling, alloy plating layers are respectively plated on the surfaces of a steel plate and a copper plate, which need to be compounded through an immersion plating or spray coating way, the thickness of each plating layer is 4-8 mu m, and each alloy plating layer contains the following components: 6-8 parts by weight of Zr, 25-50 parts by weight of Zn, 5-30 parts by weight of Al, 10-40 parts by weight of Fe, 0.5-1 part by weight of Si and 0.4-0.6 part by weight of Mo. The production method disclosed by the invention has the beneficial effects that as the bonding layers with the mixture ratio are adopted, the direct bonding property between the steel plate and the copper plate is good; in addition, the compounding temperature is lower, the rolling reduction is smaller and the working cost is saved; and the composite copper-steel material prepared by the method disclosed by the invention has the advantages of high strength, high plasticity and toughness and excellent stress and corrosion resistance.

Description

[0001] technical field [0002] The invention relates to a production method of bimetal composite, in particular to a production method of copper-steel composite plate. [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 properti...
