A short process production process of bimetallic composite strip

Abstract

The invention relates to a short-flow efficient production process of a double-metal composite belt material. The short-flow efficient production process of the double-metal composite belt material comprises the following steps: preparing a high-quality double-metal composite plate blanket with a metallurgical bonding interface by a continuous casting composite process and putting the high-qualitydouble-metal composite plate blanket into a heating furnace to heat; performing multi-pass rolling on the heated plate blanket by a rolling machine, wherein the pass reduction rate of the first passis controlled to be 50 to 70 percent, the pass reduction rate of the subsequent passes is controlled to be 25 to 45 percetn and the total rolling deformation quantity is controlled to be 85 to 95 percent; performing warm rolling forming, wherein the rolling process avoids lubrication; after performing acid-washing treatment, performing rolling forming on a cold-rolling machine, wherein the pass reduction rate is controlled to be 15 to 30 percent, the total rolling deformation quantity is controlled to be less than 90 percent and the rolling speed is 1 to 25 m / min; and performing rapid sensingheating continuous heat treatment on the composite belt material after cold rolling to obtain the double-metal composite belt material. The plate material prepared by the method is short in process flow, high in production efficiency and favorable for realizing large-scale production.

Description

technical field [0001] The invention belongs to the field of metal composite materials, and in particular relates to a short-flow and high-efficiency production process of bimetallic composite strips. Background technique [0002] With the development of science and technology, metallurgy, petroleum, chemical industry, aerospace, transportation, electronic communication, electric power, construction and other fields have higher and higher requirements for the use of materials. In many cases, a single material is difficult to meet the performance requirements of actual use. Composite materials that combine materials with different properties to improve their comprehensive performance have received increasing attention. [0003] Bimetal composite strip is a layered composite material with a sandwich structure that combines two metals together through a certain process. It combines the advantages of the two metals and has a wide range of uses. For example, the steel-aluminum c...

Problems solved by technology

But there is a problem: due to the solid-solid composite, the interface bonding strength is low

The existing problems are: the high-melting-point metal strip needs to be prepared in advance, and the surface of the strip needs to be cleaned, there is an environmental burden, and the process flow is not the shortest; the surface of the high-melting-point metal strip is easy to oxidize before compounding, and it is easy to affect the compound quality
