Abstract

The invention discloses a hole-type rolling forming method for a metal layered composite plate. The hole-type rolling forming method comprises the following steps: fixing a to-be-compounded steel plate and a to-be-compounded aluminum plate to form a steel/aluminum assembled plate blank; performing cold rolling by utilizing a hole-type cold rolling mill to prepare a steel/ aluminum layered composite plate; and preparing a to-be-compounded aluminum alloy plate, processing the steel/ aluminum layered composite plate and the to-be-compounded aluminum alloy plate, aligning and stacking according toa sequence of aluminum alloy/ aluminum/ steel/ aluminum alloy, fixing to form an aluminum alloy/ aluminum/ steel/ aluminum alloy assembled plate blank, heating to a preset temperature, rolling by utilizing a hole-type hot rolling mill to prepare an aluminum alloy/ aluminum/ steel/ aluminum alloy layered composite plate, and separating from a steel-steel interface to obtain an aluminum alloy/ aluminum/ steel layered composite plate. The hole-type rolling forming method effectively solves the problems that component metal is not coordinated in deformation, the interface is easily oxidized and the bonding strength is low in a rolling process of the steel/ aluminum alloy layered composite plate, and realizes continuous preparation of the steel/aluminum alloy layered composite plate with highinterface bonding strength and stable performance.

Description

technical field [0001] The invention relates to the technical field of metal layered composite plate preparation, in particular to a metal layered composite plate pass rolling forming method. 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 the ship adopts a steel structure, and the superstructure and deckhouse of the ship adopt an aluminum alloy structure. The connection between the steel structure and the aluminum alloy structure is the core of ship construction. question. At present, ships built at home and abroad mainly use steel-aluminum transition joints to realize the connection between steel structures and aluminum alloy structures. This transition joint has become the core component of ship construction, and its preparation technology has also become the core technology of ship material preparation. [0003] At pr...
