Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of metal composite plate preparation, and particularly relates to a multi-element metal composite plate continuous rolling equipment and method. BACKGROUND

[0002] In recent years, great achievements have been made in the fields of aviation and aerospace, national defense and military industry, transportation and equipment manufacturing in China, and the requirements for material performance have also been correspondingly improved to meet the ability to work under various different working conditions. The metal composite plate can greatly improve the performance of single metal material by firmly combining metals with different properties.

[0003] Currently, the preparation methods of metal composite plates mainly include explosion-rolling composite method, rolling composite method and casting-rolling composite method. Compared with the explosion-rolling composite method and the casting-rolling composite method, the rolling composite method has the advantages of high dimensional accuracy, uniform bonding, good continuity, high efficiency and energy saving. The rolling composite method can be divided into cold rolling and hot rolling. Compared with the cold rolling composite method, the composite plate prepared by the hot rolling composite method can alleviate the problem of thermal expansion difference and is more likely to achieve interfacial metallurgical bonding.

[0004] However, there are relatively few studies on the rolling of multi-element metal composite plates. For the rolling of four-layer metal composite plates, the four-layer metal plates are usually stacked together to form a billet, and then directly rolled in four layers at one pass to obtain a composite metal plate. However, this method is prone to problems such as deformation incoordination between the metal plates, low interfacial bonding strength, etc., which makes it difficult to effectively prepare multi-element metal composite plates. In the hot rolling process, the plate is continuously in a high temperature state due to heating treatment and rolling process, which poses a great safety hazard.
