Problems solved by technology

[0006] Aiming at the problems of sheet shape defects, interface composite quality fluctuations, and less types and sizes of billet metals that exist in the preparation of metal layered composite sheets by the current cold-hot rolling composite method
The present invention proposes to install restraint devices or restraint-tension devices respectively at the entrance and exit of the cold rolling mill and the hot rolling mill. Problems such as side bending, misalignment, lateral offset, bending, uneven thickness, warpage and the resulting fluctuations in the interface bonding quality that exist in the process of rolling and forming metal laminated composite plates can obtain high-quality metal with good plate shape laminated composite panel
The entrance restraint device of the cold rolling mill is used to exert restraint force on the width direction and the thickness direction of the metal laminated slab, and solve the side bending of the metal laminated slab or the cold-rolled pre-composite plate, the misalignment of the cladding layer and the base layer, and the lateral deflection during the cold rolling process. Move and other issues

Description

technical field [0001] The invention belongs to the technical field of metal layered composite plate rolling, and in particular relates to a rolling forming constraining system and method of a metal layered composite plate. Background technique [0002] When using the cold-hot rolling compound method to prepare metal layered composite plates, firstly, the surfaces to be compounded of two or more metal slabs are subjected to surface treatment such as mechanical grinding, and then the metal slabs are stacked to form blanks, and then The metal laminated slab is cold-rolled and pre-compounded at room temperature, and finally the cold-rolled pre-compounded plate is heated and then hot-rolled and composited to obtain a metal layered composite plate. During cold-rolled pre-composite forming, due to the different deformation resistance of different metals, the cold-rolled pre-composite plate will bend towards the metal layer with greater deformation resistance during the forming pro...
