Abstract
The utility model discloses a Ta/Zr/Ti/steel explosive welding composite plate; an explosive composite titanium plate, a zirconium plate, and a tantalum plate are arranged at a steel plate from near to far to form the composite plate; the plate and the titanium plate are arranged as transition layers between the tantalum plate and the steel plate; the thickness of the tantalum plate is 2-5mm, thethicknesses of the zirconium plate and the titanium plate are all 1.5-3mm, the thickness of the steel base plate is 20-100mm.
Description
Technical field
The utility model is to produce the metallic explosive composite plate with explosion welding method, especially belongs to alloy composite plate and makes the field.
Background technology
Tantalum belongs to rare metal, costs an arm and a leg, and the linear expansion coefficient of tantalum is 6.5 * 10 between 0～100 ℃
-6K
-1, the suiperconducting transition critical-temperature is 4.38K, the thermal neutron absorption cross section of atom is 21.3 barns.Be lower than under 150 ℃ the condition, tantalum is one of the most stable metal of chemical property.The acid solution that has only fluorine, hydrofluoric acid, fluoride ion and the sulfur trioxide that can react with tantalum.It has that corrosion resistance is good, machinability is good and combination property such as thermal neutron absorption cross section is low, and the application in capacitor, high temperature alloy, chemical industry and atomic energy industry constantly enlarges, and requirement rises year by year.Tantalum is at normal temperatures, and is all inoperative to aqueous slkali, chlorine, bromine water, dilute sulfuric acid and other many medicaments, only reaction to some extent under hydrogen fluorine and hot concentrated sulfuric acid effect, and therefore the application in chemical industry also increases gradually recently.But at home owing to be subjected to the restriction of material and price, application or less, so do not reduce under the prerequisite of service life of equipment and performance in assurance, adopt tantalum/zirconium/titanium/steel, not only made full use of properties of materials---by the contact layer of tantalum as the composite bed of contact corrosion medium, by the basic unit of steel, but also greatly reduce the cost of equipment as bearing load.
The R﹠D work of domestic tantalum/zirconium/titanium/steel because of the restriction that is subjected to multiple layer tantalum, zirconium material (because of the restriction of domestic melting technique, so far still be difficult to produce and satisfy tantalum sheet material, the zirconium sheet material that blast requires), until just begin to carry out the R﹠D work of tantalum zirconium titanium steel composite board at the end of last century from U.S.'s import tantalum material, zirconium plate, tantalum/zirconium/four layers of composite plate of titanium/steel need once detonate successfully, and two kinds of metals bump take place and rapid and whole discharge the with gas mutually between each layer.If there is one deck gas all not discharge, or explosive welding dynamic parameter such as impact velocity and angle just can not realize compound not within the specific limits between titanium and the steel.This has just limited the application of tantalum/zirconium/titanium/steel on the market of composite, tantalum/zirconium/the titanium/steel composite board of domestic pressure containers is to rely on from U.S.'s import mostly at present, not only cost an arm and a leg, and the delivery cycle is very long, be unfavorable for applying of domestic tantalum/zirconium/titanium/steel composite board equipment like this, more be unfavorable for the development of national industry.Therefore must autonomous innovation, develop the production method of tantalum/zirconium/titanium/steel composite board, this is to reducing the device fabrication cost, shortening the device fabrication cycle and will play significance.
Summary of the invention
The problem that the utility model solved is as the energy, by blast composite methods production tantalum/zirconium/titanium/steel composite board, to realize the requirement of production domesticization, to satisfy the needs of China's chemical technology development with explosive.
The technical solution of the utility model is: tantalum/zirconium/titanium/steel explosive welding composite plate is characterized in that constituting composite plate by titanium plate, zirconium plate and tantalum plate and four kinds of plates of basic unit's steel plate.Be from closely constituting composite plate on the steel plate to blast composite titanium plate far away, zirconium plate and tantalum plate; Transition zone between zirconium plate, titanium plate conduct multiple layer tantalum and the basic unit's steel plate is by the composite methods of once exploding, make it to realize large-area continuous welding, satisfy the requirement of ASTM B898-2005 " active and refractory metal composite plate " standard, the applying rate is greater than 99%, minimum shear strength τ
b〉=138Mpa.
Since in the blast recombination process in the middle of tantalum plate and zirconium plate, the titanium plate composite layered plate under the effect of explosive energy according to this to substrate accelerated motion, and form certain bending angle, could form the metallurgical binding between substrate, transition zone, compound plate.The titanium plate is easy to generate intermetallic compound at the blast recombination process, thereby reduces the applying intensity between double layer of metal.Therefore adopt little gap, little dose, but facts have proved that a large amount of jets that adopt little gap, little dose to produce can be trapped in the land of composite plate in the compound process than the large tracts of land composite plate of blast, influence is in conjunction with rate and bond strength.For this reason, we have taked parallel method to arrange in conjunction with preset angle configuration, increase the passing away of jet.Bigger support interval is reserved in limit portion between tantalum plate, transition zone, steel zone, on the tantalum plate, arranged explosive, adopt the preset angle configuration compound 6m that produced that once explodes
2About tantalum/zirconium/titanium/steel composite board.
The tantalum plate thickness is 2-5mm, and the thickness of zirconium plate and titanium plate is 1.5-3mm, and the thickness of steel substrate is 20-100mm, and plate width of cloth size can reach 1850mm * 3250mm (L * W).
It is 6m that the utility model has solved area
2The compound problem of tantalum/zirconium/titanium/steel, satisfied the needs of domestic chemical industrial development.
