Problems solved by technology

On this basis, by solving the problems of deformation coordination among various links and reasonable matching of process parameters in the whole process, a method of pre-compounding single-pass room temperature rolling, online rapid heating and single-pass temperature-controlled rolling was developed. Short process and high-efficiency preparation method of metal layered composite plate and strip combined with metallurgical compounding, changing the cumbersome process and degree of automation existing in the preparation methods of metal layered composite plate and strip such as traditional explosion compounding, explosion-rolling compounding, and rolling compounding And continuous degree is not high, material utilization rate and production efficiency are low, energy waste is serious, production cycle is long, production cost is high, there are environmental pollution and safety hazards, high requirements for equipment, it is difficult to use coiled metal strip or long size The metal sheet is used as raw material, or it cannot be used for the compounding of active metals, etc., to achieve the purpose of preparing high-performance metal layered composite plates and strips by short-process, efficient and continuous rolling in the atmospheric environment

Abstract

The invention discloses a short-process efficient production method for metal-layered composite board strips and belongs to the technical field of production of the metal-layered composite board strips. The short-process efficient production method is characterized by including: subjecting to-be-composited double-layered or multilayered metal board strips subjected to surface treatment to single-pass room temperature rolling to obtain pre-composited metal-layered composite board strip plates; rapidly heating the pre-composited metal-layered composite board strip plates to the temperature (lower than recrystallization temperature of metal) required by subsequent rolling; continuing performing single-pass temperature-controlled rolling so as to prepare high-performance metal-layered composite board strips. The short-process efficient production method has the advantages of continuity and high degree of automation, short process, high production efficiency, small environmental pollution, energy conservation, circle-time reduction, freeness of potential safety hazards, high dimensional accuracy of products, flexible specifications, large degree of freedom in raw material combination, high material utilization, low requirements on equipment, low production cost and excellent product quality and performance, and the coiled metal strip plates or long-sized metal plates can be used as raw materials.

Description

technical field [0001] The invention belongs to the technical field of preparation of metal layered composite plate strips, and in particular relates to a short-flow and high-efficiency preparation method of metal layered composite plate strips. technical background [0002] With the rapid development of the high-tech fields of the national economy and the field of national defense and military industry, especially the continuous emergence of various new technologies and new industries, the requirements for the performance of metal materials are increasing day by day. Performance has been difficult to meet the requirements of use. Therefore, the research and development of new metal composite materials (especially metal layered composite materials) and their products has become an important development direction in the field of materials science and engineering. The metal layered composite plate strip is composed of two or more component metal materials through special prep...
