Abstract

The invention belongs to the field of composite plate processing, and particularly relates to a production method for improving the yield of nickel steel composite plates, which comprises the steps of billet cogging, nickel base alloy plate prefabrication, composite plate assembly, composite plate blank rolling, composite plate blank splitting and the like. Cogging is conducted on a steel billet under multi-pass large pressure, high-pressure water is used for spraying and cooling, and coarsening of crystal grains of a composite layer of a product is restrained; the nickel-based alloy plate is prepared by adopting rolling deformation instead of machining cutting, so that the production cost is reduced, and the production efficiency is improved; all procedures are closely linked, the thickness distribution of a product composite layer from the edge part to the core part is uniform, the problem that the thickness of the rolled product composite layer is not uniform is greatly weakened, and the yield and the finished product rate of the composite plate are remarkably improved; meanwhile, the composite board with excellent comprehensive performance can be obtained through controlled rolling and controlled cooling, the heat treatment procedure is omitted, energy conservation and emission reduction of enterprises are facilitated, industrial continuous efficient production is easier, practicability is high, and the composite board is worthy of application and popularization.
