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.
