Explosive compounding method of a tantalum/zirconium/titanium/steel explosive compound plate

Abstract

The invention relates to an explosive composite method of a tantalum / zirconium / titanium / steel explosive composite plate. The specific steps are as follows: select a hard and flat area of ​​soil, lay yellow sand, and use it as a foundation after leveling; the steel plate is placed on the foundation, and the Place the first support evenly on the upper surface of the steel plate; place the titanium plate on the first support, and place the second support on the titanium plate; place the zirconium plate on the second support, place the zirconium plate on the Place the third support on the upper surface; place the tantalum plate on the third support, and paint the protective layer on the surface of the tantalum plate; lay an explosive layer on the protective layer, except laying 2# at the center of the tantalum plate For rock emulsion explosives, 1# rock emulsion explosives are placed in the rest of the positions; the detonator is placed in the center of 2# rock emulsion explosives to carry out explosive composite operations. The lamination rate and shear strength of the composite board meet the requirements of the ASTM B898 "Active and Refractory Metal Composite Board" standard, the lamination rate reaches more than 99%, and the minimum shear strength τ b ≥140Mpa.

Description

technical field [0001] The invention belongs to the field of composite plate manufacturing, and in particular relates to an explosive composite method for a tantalum / zirconium / titanium / steel explosive composite plate. Background technique [0002] Metal tantalum is a light gray metal with a slight blue color. Due to its many unique properties, it has a wide range of applications. Tantalum is very hard and its hardness can reach 6-6.5. Its melting point is as high as 2996 ° C, ranking third after tungsten and rhenium. Tantalum is malleable and can be drawn into filaments or made into thin foils. Its thermal expansion coefficient is very small, and it only expands by 6.6 parts per million per degree Celsius. In addition, its toughness is very strong, even better than copper. Tantalum also has very good chemical properties and is extremely resistant to corrosion. No matter in cold or hot conditions, it has no reaction to hydrochloric acid, concentrated nitric acid and "aqua...

Problems solved by technology

[0003] At present, most domestic tantalum / zirconium / titanium / steel explosive composite panels rely on imports from abroad, which is not conducive to the popularization and application of tantalum / zirconium / titanium / steel explosive composite panel equipment in my country, and is not conducive to the development of national industries.
