Abstract

The invention discloses a preparation process of a multilayer metal composite belt, and relates to the technical field of preparation of multilayer metal composite belts. The preparation process comprises the following process steps: (S1) selecting raw materials for low-temperature annealing; (S2) polishing and cleaning the selected raw materials; (S3) nesting and assembling the treated raw materials; (S4) forging and pre-deforming the assembled sleeve blank to form a sleeve blank with a sharp wedge-shaped front end; (S5) cold-rolling and compounding the pre-deformed sleeve blank; (S6) diffusing and annealing the cold-rolled and compounded metal composite belt; (S7) carrying out multi-pass cold rolling and thinning on the heat-treated metal composite belt; and (S8) secondarily diffusing and annealing the cold-rolled and thinned multilayer metal composite belt. The obtained multilayer metal composite belt is flat and smooth in surface and high in binding force; and compared with the prior art, the preparation process is low in requirements on production equipment, high in raw material combination freedom degree, flexible in product specification, simple in preparation process, low in production cost and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of preparation of multilayer metal composite strips, and more specifically relates to a preparation process of casing rolling multilayer metal composite strips. Background technique [0002] Multi-layer metal composite strip is a new type of material that synthesizes two (or more than two) metal materials with different physical, chemical or mechanical properties through appropriate processing technology and has the advantages of all components. Compared with traditional single metal materials, multi-layer metal composite strip has many advantages such as low cost, energy saving, high strength and excellent corrosion resistance, electrical conductivity, thermal conductivity, magnetic permeability, formability, weldability, etc. Significant economic benefits, widely used in aerospace, transportation, national defense, electronic information, petrochemical, instrumentation and other fields, with extremely broa...
