Description
Technical Field
The invention belongs to the technical field of composite metal, and particularly relates to a multilayer composite copper plate and a manufacturing method thereof.
Background
The clad steel sheet is a steel sheet formed by cladding a single or more than one metal by explosion, rolling, explosion rolling or the like. The composite steel plates are of various types, and can be divided into two main types according to the combination type, namely metal composite steel plates and non-metal composite steel plates. The metal clad steel plate is formed by cladding other metal cladding layers on the surface of a steel plate, such as a stainless steel clad steel plate, a titanium clad steel plate, a copper clad steel plate, an aluminum clad steel plate and the like. The non-metallic clad steel sheet is formed by compounding a base steel sheet and a viscoelastic resin having excellent vibration damping properties, such as a lightweight clad steel sheet and a vibration damping clad steel sheet.
At present, the method for industrially producing the metal composite plate mainly focuses on two major types, namely an explosion cladding method and a rolling cladding method. Rolling and compounding are taken as a traditional production method, hot rolling is mainly taken as a main method, namely, metals needing compounding are heated and then rolled and compounded. In the hot rolling process, the blank needs to be heated to enable the liquid adsorption film of the component metals on the composite front surface to be volatilized and embrittled, and the metals at the joint part are recrystallized and diffused when in composite deformation. The real combination area of the two components contacted after hot rolling can influence the composite strength of the composite material. The prior art is provided with technical data for improving the composite strength of the composite material by influencing the bonding area.
