The invention provides a preparation method of a high strength bimetallic composite plate in order to promote the diffusion of the composite layer elements and improve the diffusion efficiency. The preparation method of the high strength bimetallic composite plate comprises the following steps: I raw material pretreatment, II coating of isolation agent, III coating of an energizer, IV billet formation, V heating, VI rolling and VI finishing. The preparation method the high strength bimetallic composite plate employs the energizer, and has the beneficial effect of: (1) promoting the diffusion of elements, and improving the diffusion efficiency; and (2) shortening the heating time to achieve energy saving and emission reduction.

Description

technical field [0001] The invention relates to a method for preparing a metal composite plate, in particular to a method for preparing a bimetallic composite plate by a rolling method, and belongs to the field of composite metal material processing. Background technique [0002] With the development of modern science and technology, various new technologies and new processes are constantly emerging. In production practice, people continue to put forward new and higher requirements for the performance of materials; at the same time, more and more precious metals or rare Metal is used to manufacture various structures or equipment that require corrosion resistance, wear resistance, and high temperature resistance. In many cases, it is difficult to use a single metal material to meet the dual requirements of engineering structures for their performance and cost. Therefore, composite materials prepared by special processes came into being, and metal composite panels are one of ...
