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...
