Preparation method of rolled laminar metal composite board blank

Abstract

The invention provides a preparation method of a rolled laminar metal composite board blank and belongs to the technical field of a preparation method of a metal composite board blank. The preparation method is used for preparing the rolled laminar metal composite board blank in a low-cost and high-efficiency manner. According to the technical scheme, the preparation method comprises: punching a non-through round hole in a base material plate blank, and storing a reducing vacuum treatment agent in the hole; after aligning a surface to be compounded of a base material (1) with a surface to be compounded of a coating material (2), welding along a peripheral groove; after conveying the blank into a heating furnace, enabling the reducing vacuum treatment agent and a main component of air in a compounding cavity to react at high temperature, wherein a reaction product is solid particles, the compounding cavity reaches a near-vacuum state, a surface to be compounded of a steel plate is not oxidized, oxidization-free metallurgical bonding of the surface to be compounded in a post-period rolling process is guaranteed and a metal composite board with good performance is obtained. The invention provides innovation of the preparation method of the rolled laminar metal composite board blank, and the preparation method is greatly better than an existing explosion method and a vacuum welding method; the preparation method is simple in process, low in cost and high in production efficiency, and has remarkable economic benefits.

Problems solved by technology

[0003] At present, the explosion method is mainly used to produce layered metal composite panels (metal composite materials) at home and abroad, and the technology is quite mature, but the explosion method has the following unavoidable shortcomings: most of the explosions are carried out in the open air, the degree of mechanization is low, and the working conditions are poor. , and limited by the climate, the noise and vibration generated during the explosion will also affect the surrounding environment; the explosion area cannot be too large, and continuous production cannot be performed, so the output is small and the productivity is relatively low

However, this method must be carried out in a vacuum chamber, which has the disadvantages of large equipment investment and low production efficiency.
