Embodiment

[0048] like figure 1 , 2 , 3, 4, 5, 6, adopt the method of the present invention to prepare carbon copper-aluminum composite board:

[0049] 1) Material: Select pure aluminum plate as the substrate 1, the plate size is 200mm (length) × 50mm (width) × 2mm (height), pure copper plate is used as the double plate 2, the plate size is 200mm (length) × 50mm (width) × 8mm (high). First, the cleaned pure copper plate and pure aluminum plate are subjected to stress relief annealing treatment in the heating furnace 8, so that the plate structure is more uniform, the plasticity of the plate is improved, and it is beneficial for the plate to realize compounding. Use a grinding tool equipped with a wire brush to grind the surface to be bonded of the pure copper plate and the pure aluminum plate after stress relief annealing to a “sand surface” effect to remove oxides on the surface of the slab and create favorable conditions for copper-aluminum compounding.

[0050] 2) Blank assembly: s...

Abstract

The invention belongs to the field of rolling of metal composite plates, and particularly relates to a method for smoothing continuous ply rolling of metal-based composite plates. The method comprisesthe steps of rolling a blank by using a two-roll mill with corrugated rolls on the top and the bottom to obtain a corrugated composite plate of which the upper surface and the lower surface are corrugated; carrying out annealing treatment; heating or cooling the annealed composite plate to a required temperature according to process requirements; and rolling and flattening the composite plate byusing a two-roll mill or four-roll mill with common flat rolls on the top and the bottom to obtain a corrugated flattened composite plate of which the upper surface and the lower surface are planes. During first-pass rolling through the corrugated rolls, rolling force changes in a stepped manner, thus, large stress can be generated at a position of a trough of a rolled piece, metallurgical bondingof metals is promoted and is gradually diffused towards two sides, during second-pass rolling through the flat rolls, the original wave crest position with small stress can generate peak stress againdue to increasing of rolling reduction, and metallurgical bonding on a whole contact surface is promoted again.

Description

technical field [0001] The invention belongs to the field of metal composite plate rolling, and in particular relates to a wave flat continuous stack rolling method for metal matrix composite plates. Background technique [0002] Advanced material preparation technology is the key technology supporting the development of modern industry and the material basis for national economic development. Metal layered composite material is a composite material that uses unique and advanced technology to form a metallurgical bond between two or more metal materials. The components of metal layered composites are independent of each other, but the final performance of the material is not a simple superposition of components, but an extremely important improvement. By selecting appropriate materials and reasonable process design, materials that meet different conditions can be produced, such as light weight, high electrical and thermal conductivity, and excellent properties such as impac...
