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. When the plastic cold rolling is compounded, although the billet is cleaned by a wire brush and the first-pass deformation reaches 70%, there is no crack on the surface. The result is that the billet is squeezed into the crack of the steel with a thin oxide film on the original surface and compounded with the steel (further increasing the amount of deformation in the first pass is limited by the capacity of the rolling mill), so the bond is very fragile, the bond strength is low and unstable

Description

technical field [0001] The invention relates to the technical field of composite rolling, in particular to a composite alloy plate and a preparation method thereof. Background technique [0002] In the prior art, copper-steel composite materials are usually prepared by hot-rolling and cold-rolling composite methods. [0003] The hot-rolling composite method is a process method in which the composite metal billet is rolled and deformed under high temperature and high pressure, and different metals are combined under the combined action of heat and force. It has the advantages of simple process and high production efficiency. Hot-rolling cladding is a commonly used cladding method of solid-phase bonding, and its process generally includes 3 steps: firstly, cleaning of the bonded surface, including degreasing and deoxidizing film. Keep the surface to be bonded clean; then carry out initial bonding, and make the component metals undergo plastic deformation together through high...
