Abstract

The invention discloses a corrugated-flat rolling composite method for steel / aluminum / aluminum alloy layered composite plates. Firstly, a steel / aluminum layered composite plate with good plate shape and firmly bonded interface is prepared, and corrugated cold rolling with a large thickness ratio is used. Enhance the deformation of the interface to be compounded, coordinate the metal deformation of the components, and solve the problem of non-deformation at the steel-aluminum interface; then use the interface wave-flat hot rolling to coordinate the deformation of the components, realize the composite of aluminum and aluminum alloys, and prepare high-performance steel / aluminum / Aluminum alloy layered composite plate; using the advantage that interface oxidation has little effect on the combination of aluminum and aluminum alloy, the problem of oxygen prevention in the compounding process is eliminated; finally solved the problem in the rolling process of steel / aluminum / aluminum alloy layered composite plate with a thickness of more than 4mm Because the steel-aluminum joint surface is close to the neutral layer, the interfacial shearing effect is weak, the interfacial bonding mainly depends on hot-pressing, etc., resulting in low interfacial bonding strength, and the deformation caused by the large difference in properties between steel, aluminum and aluminum alloy. coordination problem.

Description

technical field [0001] The invention relates to the technical field of metal layered composite plate preparation, in particular to a wave-flat rolling composite method of steel / aluminum / aluminum alloy layered composite plate. Background technique [0002] In order to reduce the ship's center of gravity, reduce the weight of the ship, increase the speed of navigation, and increase the stability of navigation, the main hull of a large ship is now constructed with a steel structure, while the superstructure and deckhouses are constructed with an aluminum alloy structure. The connection between the steel structure and the aluminum alloy structure is The core problem of ship construction. At present, steel-aluminum transition joints are mainly used to connect steel structures and aluminum alloy structures in the process of building ships at home and abroad. This transition joint has become the core component of ship construction, and its preparation technology has also become the...
