Problems solved by technology

At present, the area of ​​thick clad zirconium / titanium / steel metal composite panels does not exceed 1.5m 2 The composite process is relatively stable, and when the area of ​​the thick clad zirconium / titanium / steel metal composite plate exceeds 1.5m 2 When explosively compounding thick zirconium plates, if the bonding strength of the titanium-steel interface is not high when the thin titanium plate and the steel plate are explosively compounded, and the large-scale thick zirconium plate is subjected to excessive tension on the titanium plate during the explosive compounding, it is easy to cause the titanium plate and the steel plate to Separation, leading to production failure of thick clad zirconium / steel metal composite panels

Abstract

The invention discloses a method for preparing a large-scale thick multi-layer zirconium / steel metal composite plate. The method includes: 1. selecting a zirconium plate and a steel plate according to the target product steel metal composite plate; 2. polishing the surface of the zirconium plate to obtain a composite three-layer zirconium plate; three, spraying titanium powder on the composite-layer zirconium plate to obtain a composite-layer zirconium plate with a titanium coating on the surface; four, performing leveling and annealing sequentially on the composite-layer zirconium plate with a titanium coating on the surface, Then carry out surface treatment and explosive compounding with the steel plate to obtain the zirconium / steel metal composite plate body; fifth, level the zirconium / steel metal composite plate body sequentially and anneal to obtain the zirconium / steel metal composite plate. The method of the present invention firstly prepares titanium coating on the composite layer zirconium plate, and then explosively composites it with the steel plate, avoids the titanium plate and the steel plate being explosively composited first and then separated in the subsequent composite due to the low bonding strength, and realizes large-scale thick multilayer zirconium / Preparation of steel-metal composite panels.

Description

technical field [0001] The invention belongs to the technical field of metal composite material preparation, and in particular relates to a preparation method of a large-scale thick multilayer zirconium / steel metal composite plate. Background technique [0002] Zirconium / steel metal clad plate is a layered metal clad plate with zirconium as the cladding metal and steel plate as the base metal. It is widely used in the manufacture of components, equipment and containers in important fields such as acetic acid engineering, caustic soda and atomic energy industry. At present, the production cost of zirconium / steel composite panels in China is high and the yield is low, especially the large-scale thick clad zirconium / steel metal composite panels, which is not conducive to the popularization and application of its equipment and containers, and is not conducive to the development of industry. In recent years, with the development of industrial technology, the demand for large-form...
