Abstract

The invention relates to a short-process preparation method of a multi-layer metal composite plate and belongs to the technical field of short-process preparation of metal composite plates. The technology is characterized in that a corresponding centrifugal casting composite tube blank is chosen through calculation according to the innerlayer and outerlayer components and dimensional requirement of a finished product; the composite tube blank is dissected into 2 to 10 tile shapes along the direction of a vertical axis, with a fan-shaped cross section, and the central angle Alpha is 40 to 120 degrees; the blank cut is put into a heating furnace to be heated with the heating temperature of 1050 to 1280 DEG C and the time at maximum temperature of 0.5 to 5 hours; composite plates with various specifications are manufactured through hot rolling transformation; and a sheet metal is continued to be cold-rolled and transformed to produce the sheet metal with the thickness of 0.1 to 3mm. The technology is short in process, simple in operation, and high in bonding strength of layers of the composite plate produced and eliminates the nonuniform phenomenon of interface organization through the technologies of heating and transformation.

Description

technical field

[0001] The invention belongs to the technical field of short-process preparation of metal composite panels, and in particular provides a short-process preparation method of multilayer metal composite panels, which is aimed at metal composite panels used in industries such as pressure vessels, cutting tools, and petrochemical industries. Background technique

[0002] Metal composite panels are made of two or more different materials (such as carbon steel, stainless steel, copper, aluminum, titanium, nickel and other alloys), combined through various connection technologies, and have the advantages of each layer of materials Compared with the traditional single-layer metal plate, the two-layer or multi-layer metal composite plate can save the amount of precious alloy on the one hand, and has good comprehensive performance on the other hand. For example, combining a metal with higher strength and a metal with better toughness can unify the overall strength and t...
