Abstract

The invention discloses a method for rolling a high-strength metal composite plate. The method is characterized in that a metal substrate and a cladding plate are selected, it is required that the deformation resistance of the metal substrate is larger than that of the cladding plate, the composite faces of the substrate and the cladding plate are cleaned, the substrate with the large deformation resistance is machined to obtain the substrate with a corrugated face on the composite face, the section of each corrugation is in an arc shape or a sinusoidal wave shape or an oval shape, and the height s of the corrugations, the width t of the corrugations and the thickness h0 of a metal layer with the large deformation resistance satisfy the conditions that s / h0 ranges from 0.1 to 0.8, 2s / t is equal to tan alpha, and alpha ranges from 10 degrees to 40 degrees; the substrate and the cladding plate are stacked and pressed in sequence, and a double-layer composite plate blank is obtained; and a composite plate strip is obtained after rolling is conducted according to the warm-rolling process or the hot-rolling process. By the adoption of the method, the problem of difference of metal plastic deformation caused by different degrees of deformation resistance of dissimilar metals is solved, and the curved surface of the substrate makes compensation for the difference, so that the rolled cladding layer and the rolled substrate layer are matched in length without buckling, and meanwhile the binding force between the substrate and the cladding plate is increased through traction on the cladding plate of the corrugations of the substrate.

Description

technical field [0001] The invention belongs to the technical field of material processing of metal composite strips, and in particular relates to a method for rolling high-strength metal composite strips. Background technique [0002] With the rapid development of science and technology, the birth of a number of high-tech industries has put forward higher requirements for the performance of materials. At the same time, in order to reduce costs, save resources, reduce energy consumption, and improve product performance, scholars at home and abroad are committed to Research and develop new bi-metal or multi-metal composite plates and new rolling processes. Metal composite material technology can give full play to the respective advantages of component materials, realize the optimal allocation of component material resources, save precious metal materials, and achieve performance requirements that cannot be met by a single metal. It is mainly used in anti-corrosion, pressure v...
