Problems solved by technology

The P.T. method (also known as the three-step method) proposed by Metals & Control Corp of the United States is difficult to achieve a large single-pass deformation rate for simultaneous rolling
The current hot rolling, in order to eliminate the problem of oxidation and brittle metal compounds in the production process, often costs a lot

Abstract

A method for preparing a copper-steel composite plate, the method steps are: placing the steel plate on the bottom, placing the copper plate on it, fastening the two metal plates on the workbench, selecting a stirring head whose length is slightly greater than the thickness of the copper plate Clamped on the friction stir welding machine. The technical effect of the invention is that the quality of the joint is good and stable, the preparation process is controlled by a machine, the parameter setting is easy to monitor, and the repeatability is good.

Description

technical field [0001] The invention relates to a preparation method of a composite board, in particular to a preparation method of a copper-steel composite board. Background technique [0002] In order to maximize the performance of metal materials, one of the methods is to combine materials with different properties to make composite panels. Due to the excellent properties of both copper and steel, copper-steel clad plates have a wide range of applications, such as in the automotive industry, copper-steel clad plates are used to manufacture heat exchangers, synchronizer cone rings, reducer worm gears, bearing bushes, etc. in the metallurgical industry , Use copper-steel composite plates as electrodes for electroplating technology, processing electrodes for electrical discharge, grounding rods, etc. [0003] There are currently three methods of preparing copper-steel clad plates: hot rolling clad method, explosive clad method, and liquid-solid phase rolling clad technolog...
