Compound cast-rolling device for metallurgical bonding of liquid aluminum base strip and single metal or alloy strip

Abstract

The invention discloses a compound cast-rolling device for metallurgical bonding of a liquid aluminum base strip and a single metal or alloy strip. The compound cast-rolling device comprises a cast-rolling machine (7) and a lip device (8) which are fixed onto a board (6). The compound cast-rolling device is characterized by further comprising one or two coiling machines (2), leather-alloy strips (1) are coiled on the coiling machines, are directly led into a compound region at the front end of the cast-rolling machine (7) through a guiding and drawing mechanism and contact with the surfaces of core-liquid base materials fed by the lip device (8), and the leather-alloy strips and the core-liquid base materials are continuously rolled by a roller of the cast-rolling machine to form a metallurgically bonded metal compound strip. The compound cast-rolling device solves the problems that an existing cast-rolling device is large in size, high in investment cost, complicated in compound technology and long in production cycle, and compound interfaces cannot be metallurgically bonded. The compound interfaces of the compound strip can be metallurgically bonded, the production cycle is shortened, production procedures are decreased, production efficiency is improved, production cost is reduced, and post processing quality of the compound strip is ensured.

Description

technical field [0001] The invention belongs to the technical field of composite casting and rolling equipment, and mainly relates to a liquid aluminum substrate strip combined with a single metal or [0002] Alloy strip metallurgical combination of composite casting and rolling equipment. Suitable for the production of all metal composite strips. technical background [0003] With the rapid development of science and technology, different metal materials are combined into one through various connection methods to prepare metal composite strips, and the physical, chemical and mechanical properties that single-layer metal materials do not have can be obtained. Corrosion resistance, fatigue resistance, electrical conductivity, good stability requirements at working temperature, and can reduce costs at the same time. Therefore, the development of new metal composite materials has very urgent practical significance, and will certainly bring significant economic and social bene...

Problems solved by technology

[0006] The purpose of the present invention is to propose a composite casting and rolling equipment in which liquid aluminum substrate strips are metallurgically combined with a single metal or alloy strip, which solves the problems of large volume, high investment cost, complex composite process, long production cycle and complex composite casting equipment. The interface can not achieve the problem of metallurgical bonding, so that the metallurgical bonding between the bonding interface of the composite plate can be realized, so as to shorten the production cycle, reduce the production process, improve the production efficiency, reduce the production cost, and ensure the quality of the post-processing of the product.
