Problems solved by technology

The current production method has disadvantages such as complex production process, high production cost, low efficiency, low composite strength, and unstable product quality. Especially when aluminum is composited with copper, the problem of aluminum oxidation is difficult to solve, and the current production method can only A single plate is produced, and continuous aluminum and copper composite metal strips cannot be obtained

Abstract

The invention discloses a production method of an aluminum and copper composite metal band. In the method, the aluminum and copper composite metal band is manufactured by anaerobic continuous casting and rolling of semisolid aluminum or aluminum alloy and a solid copper band. In the production method of the invention, the anaerobic metallurgical combination of the solid copper band and molten aluminum is realized, the aluminum oxidization problem is solved, the combined strength is high, and the aluminum and copper bonding strength is more than or equal to 100MPa; the continuous casting and rolling of the copper band and the molten aluminum are adopted to produce the aluminum and copper composite metal band, so the production efficiency is greatly improved by scores of times and the product quality is stable; the produced aluminum and copper composite metal band retains the original surface quality of the copper band, has a uniformly-thick copper layer and can be deeply processed by cold rolling; and the copper band and the molten aluminum, which comprise different components, can be used, and products are diversified and widely applicable. The method has the advantages that: the production process of the copper and aluminum composite band is advanced and comprises a few working procedures; and the energy-saving, material-saving and economic effects are obvious.

Description

technical field [0001] The invention relates to the technical field of metal strip production, in particular to a production method of aluminum and copper composite metal strip. Background technique [0002] Copper and aluminum are important non-ferrous metals, which are widely used in industrial and civilian fields. Copper has good electrical and thermal conductivity, corrosion resistance, and antibacterial properties, and aluminum has good electrical and thermal conductivity. Compared with aluminum, copper resources are scarce, and aluminum resources are abundant, and the proportion of aluminum is small, and the price is low. Aluminum and copper composite metal strip is a kind of bimetal with aluminum as the matrix and copper-coated outer layer. It combines the high-quality electrical conductivity and low-cost resources of aluminum with the high chemical stability of copper and low contact It is a new type of conductor material and decoration material that integrates resi...
