Abstract
The utility model discloses an explosively clad plate of NAS625 alloy and steel plate, wherein the composite board is formed by the explosion of the NAS625 alloy plate and steel plate baseplate; the thickness of the NAS625 alloy plate is 2-20mm; and the thickness of the steel plate baseplate is 20-100mm. The explosively clad plate can be manufactured with low cost, is used in host materials of chemical equipment in sets, nuclear power stations, marine equipment, jet aircraft engine components, aviation materials, heat treating furnace materials, evaporators and the like.
Description
Technical field
The utility model relates to a kind of metallic composite panel, and the composite metal plate of the complex method that especially explodes belongs to composite metal plate and makes the field.
Background technology
NAS 625 is the solution strengthening nickel-base alloys that add Mo and Nb element on the basis that is basic element with Ni-Cr.Because having superior corrosion resistance has both good hear resistance simultaneously, therefore extensively be used in chemical equipment in sets, garbage incinerating system etc. but the cost height of NAS 625 alloys, large-scale production and application are also very restricted.So NAS 625 alloys and common metal composite need be used.NAS 625 alloy clad steel plates have good application prospects at chemical equipment in sets, nuclear power station, oceanographic equipment, aerojet engine parts, aircraft material, heat-treatment furnace material, evaporimeter or the like.
Explosive welding is the frontier branch of science of boundary between metal physics, explosion physics and welding science.It is the new and high technology a kind of of great practical value of carrying out the intermetallic welding and producing metallic composite as the energy with explosive.Its essence is that a kind of is the new technology and the new technology of metal solder of Pressure Welding, melting and the diffusion welding (DW) ' Trinity ' of the energy with the explosive.
It is the high-voltage pulse load that produces by explosive detonation, promote the another kind of material (base material) of a kind of material (multiple material) high speed inclined impact, its loading stress is higher than the yield strength of metal material far away, the moment property of loading procedure (one is a trace level), the locality of material stand under load, modes such as the small adjacent domain that occurs in application point of interweaving and moving at a high speed realize the metallurgical binding of two kinds of metals, and the land is rendered as wavy metallurgical alloy.It is again to do the new and high technology a kind of of great practical value that the energy carries out the intermetallic welding and produces metallic composite with explosive that blast is conciliate.Its maximum characteristics are can be with metallic combination in moment, and simple, rapid and strong welds together.The advantage of comparing explosion welding technique with solder technology such as rolling, built-up welding, casting is:
The adaptive solderability of material widely, be applicable to most plastic-metal or alloy: especially for the welding of large-area metal, can be described as unique method of attachment: the combination that is not only applicable to the intermiscibility metal, and be applicable to the combination of non-intermiscibility metal, also be applicable to the Metal Substrate alloy of compound between easy generation brittle metal; Have good easily hot, low interface resistance, the land does not have the heat affected area and constitutes good joint performance, and the thermal process of moment does not have the interface or a spot of dissolving only arranged.
Summary of the invention
The utility model purpose is, with explosive as the energy, produce NAS 625 alloys and iron and steel composite plate by the blast composite methods, thereby making full use of NAS 625 alloys effectively shields under the condition of thermal neutron, reduce use cost, guarantee to satisfy the equipment needs of industries such as China's ocean engineering, medical complete set of equipments, food complete set of equipments, salt making equipment, environmental protecting device.
The technical solution of the utility model is: the explosive clad plate of NAS 625 alloys and substrate steel sheet, the thickness of NAS 625 alloy sheets are at 2-20mm, and substrate steel sheet thickness is 20-100mm.
In minor face, arrange the higher explosive of explosion velocity after adopting support pad installation, explosive shop to put and finish between multiple layer NAS 625 alloy and the basic unit's carbon steel sheet, finally make it to realize the large-area continuous welding of sieve, exploding can make the applying rate reach 100% after the compound one-shot forming, minimum shear strength τ b 〉=210Mpa.
The blast of NAS 625 alloys-steel composite board is compound to be that steel plate is as other one deck of bearing load the top layer of NAS 625 alloys as load surface.Exploding compound is to be the energy with the explosive, in the moment of igniting, explosive potential chemical energy, promptly be converted into luminous energy, acoustic energy, heat energy and mechanical energy.Exploding compound is exactly heat energy and the mechanical energy of utilizing explosive to discharge, under the effect of high-voltage pulse load, make compound plate under the effect of explosive energy successively to substrate accelerated motion, and form certain bending angle, could form interatomic combination between base, compound plate.
The beneficial effects of the utility model are: the material of main part that can be used for chemical equipment in sets, nuclear power station, oceanographic equipment, aerojet engine parts, aircraft material, heat-treatment furnace material, evaporimeter etc. with the lower cost manufacturing.

The specific embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
The blast of NAS 625 alloy sheets-substrate steel sheet is compound: above when installing at the scene NAS 625 alloy sheets being placed on, steel plate is as a following laminar substrate, at first support the gap between two plates and strengthen employing 10mm, the edge supports gap, parallel placement, to satisfy the whole average needs of the stressed distribution of sheet material, guarantee that final composite plate mechanics performance reaches balance, and understand burn compound plate face greatly for fear of dose in the blast recombination process, overcoat also will be thickeied.The thickness of NAS 625 alloy sheets is at 2-20mm, and substrate thickness is the 20-100mm steel plate, and the main body explosive is selected the 2# rock explosive for use, explosion velocity 2200～3200mm/s.NAS is protected on 625 alloy sheets surfaces the back and is evenly arranged the 2# rock explosive, at the 1# explosive of arranging a high explosion velocity along widthwise edges, its explosion velocity 5000～6500mm/s, medicinal strip thickness are higher than main body explosive 10mm, width is 15mm, and fire point is placed on NAS 625 alloy edges of boards portion (see figure 1)s.Explode compound after, through heat treatment, leveling, the applying rate is 100%, shear strength τ b 〉=210Mpa.The explosive clad plate of NAS 625 alloys and steel plate constitutes the material of using of lower costs such as chemical equipment in sets, nuclear power station, oceanographic equipment, aerojet engine parts, aircraft material, heat-treatment furnace material, evaporimeter after machine-shaping.
