Problems solved by technology

[0004] However, when the titanium transition layer is used to prepare the zirconium / steel composite plate, when the zirconium plate is composited on the steel plate with the titanium transition layer by explosive welding, the titanium / steel interface will bear an explosion impact again, which will affect the combination of the titanium / steel interface. It is unfavorable, and in serious cases, there will be no bonding phenomenon; at the same time, due to the increase of the titanium transition layer and the steel explosive welding process, the composite plate needs to be annealed, leveled, and surface treated before the zirconium plate is combined, which significantly increases Composite panels are difficult to prepare, which reduces operability and is not conducive to mass production

Description

technical field [0001] The invention belongs to the technical field of layered metal composite material processing, and in particular relates to a preparation method of a zirconium / steel composite plate. Background technique [0002] Zirconium is a passivation metal, which can react with oxygen in the air at room temperature and form a very dense passivation film on the surface. The alloy has excellent corrosion resistance. At the same time, zirconium has excellent mechanical properties and thermal conductivity, and is suitable for use as pressure vessel shells, heat exchanger tube sheets, tower components, and pipes. Zirconium / steel, zirconium / stainless steel, tantalum / zirconium / titanium / steel composite plates prepared by explosive welding technology not only comprehensively utilize the advantages of zirconium, steel, stainless steel, tantalum and titanium, but also save zirconium resources and reduce equipment cost , It provides a practical and reliable way to meet the s...
