Embodiment Construction

[0042] The composite billet 1 is sent to the heating furnace 2 by the transport roller table for heating. After being released from the furnace, it is dephosphorized by high-pressure water, and then enters the four-roll reversible rolling mill 4 for multi-pass reversible rolling. After rolling to the size of the intermediate billet, usually 20mm, after After the post-tension bending unit 5 is deformed, it enters the post-crimping heating furnace 6 for heat preservation and coiling. The plate tail during this process cannot be separated from the front bending unit 3 and the rolling mill 4. This is done to facilitate smooth strip threading in the coiling furnace during reverse rolling. coiled.

[0043]After the first rolling pass of coiling is completed, the four-high reversing rolling mill 4, the post-tension bending unit 5 and the post-crimp heating furnace 6 are reversely rotated to start reverse rolling. The strip tail after the first pass of rolling enters the front coiling...

Abstract

The invention provides a multilayer metal coupling deformation rolling combined method and device. The device comprises a compound blank heating furnace, a high-pressure water descaling machine, a four-roller reversible rolling mill, a front reeling holding furnace, a rear reeling holding furnace, a front board criss cross bending deformation unit, a rear board criss cross bending deformation unit, a laminar cooling unit and a finished product reeling machine. According to the method, the reeling heating furnaces are equipped in front of and in rear of the single-frame four-roller reversible rolling mill, and the tension bending units are arranged between the front reeling furnace and the rear reeling furnace, the tension bending rollers are flower rollers of which the surfaces are of a convex and concave structure, three flower rollers form a reverse bending deformation unit, and a convex-concave structure of a front roller surface and a convex-concave structure of a rear roller surface are arranged in a staggered mode, so that a temperature controlling reeling coupling deformation rolling combined mechanism used for applying tension and achieving board criss cross bending deformation is formed, residual stress of a compound interface is remarkably reduced, and board shape quality is ensured; and meanwhile, the bonding strength and binding rate of the compound interfaces are greatly improved, the structure performance and comprehensive mechanical performance of composite boards are improved, and the production efficiency and yield are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of dissimilar metal composite plates, and in particular relates to a method and device for curling, temperature-controlling, tension-bending, coupling, deformation-rolling and compounding of multi-layer metal materials. Background technique [0002] Layered metal composite materials can give full play to the performance characteristics of each component material, and have comprehensive excellent characteristics such as high strength, high toughness, high temperature resistance, corrosion resistance, oxidation resistance, and high cost performance. They are urgently needed in aerospace, petrochemical, nuclear energy, shipbuilding and other fields. structural materials. [0003] In today's increasingly tense energy and resources, it is also more prominent in the efficient utilization of resources. The development of multilayer metal composite sheet strip preparation methods and devices is a key ...
