Description
Technical field
The utility model produces metallic explosive composite plate by Explosion composite method, and it belongs to composite plate and manufactures field.Especially NS312 alloy sheets and steel plate explosive clad plate.
Background technology
NS312 alloy is nickel-chromium-iron-based solid solution strengthened alloy, has good high-temperature corrosion resistance and antioxygenic property, excellent cold and hot working and welding technological properties, has satisfied heat resistance and high plasticity below 700 DEG C.NS312 alloy all has corrosion resistance for various corrosive medium.The composition of chromium makes this alloy under oxidative conditions than nickel 99.2 (alloy 200) and nickel 99.2(alloy 201, low-carbon (LC)) there is better corrosion resistance.Meanwhile, higher nickel content makes alloy have good corrosion resistance in reducing condition and alkaline solution, and effectively can prevent chloro-iron stress corrosion cracking.NS312 alloy has good corrosion resistance in the organic acids such as acetic acid, acetic acid, formic acid, stearic acid, has medium corrosion resistance in mineral acid.In the high-purity water once used with secondary cycle in nuclear reactor, there is very outstanding corrosion resistance.Especially outstanding performance is the corrosion can resisting dry chlorine gas and hydrogen chloride, and application of temperature reaches 650 DEG C.At high temperature, the alloy of annealed state and solution treatment state has good anti-oxidant spalling resistance and high strength in atmosphere.This alloy also can resist ammonia and nitriding, carburizing atmosphere, but Redox Condition alternately change time alloy can be subject to the corrosion of partial oxidation medium.
NS312 sheet alloy lists ASTM standard B-168 in.But at home due to the restriction by material and price, application or less, so under guarantee does not reduce the prerequisite of service life of equipment and performance, adopts NS312 plate/steel plate composite plate, not only takes full advantage of properties of materials---pass through explosive welding; By the cladding of NS312 alloy as contact corrosion medium, by the basic unit of steel as bearing load, but also greatly reduce the cost of equipment.
The NS312/ steel composite board of current domestic pressure containers relies on from external import mostly, not only expensive, and the delivery cycle is very long, is unfavorable for applying of China NS312/ steel composite board equipment like this, is more unfavorable for the development of national industry.Therefore necessary autonomous innovation, develops the manufacture craft of large face NS312/ steel composite board, and this will play significance to reduction device fabrication cost, shortening device fabrication cycle.
Utility model content
The problem that the utility model solves is, using explosive as the energy, produces NS312/ steel composite board by the method for Explosion composite, to realize the requirement of domesticizing, meets the needs of the industry developments such as China's chemical industry.
The technical solution of the utility model is: NS312 alloy sheets and steel plate explosive clad plate, it is characterized in that being made up of NS312 alloy sheets and steel plate Explosion composite, and NS312 alloy sheets thickness is 3-8mm, and steel plate thickness is 20-100mm.
Length and the wide size of steel plate reach 10000mm × 2500mm, the length of NS312 alloy sheets and the length of the corresponding steel plate of wide difference and wide 95-99%.
Cladding NS312 alloy sheets (4) should lay larger dose, by the mounting arrangements of explosion scene angularly method, finally make it to realize large-area continuous welding, meet the requirement of NB/T47002.2-2009 " pressure vessel Explosive Clad Steel Plate Part II: nickel-steel composite board " standard and ASME SA-265 " nickel and nickel-based alloy composite steel plates " standard, laminating rate can reach more than 99%, minimum shear strength τ
b>=210Mpa.
The Explosion composite of NS312/ steel composite board is that steel plate is as the basic unit of bearing load using the cladding of NS312 alloy sheets as contact corrosion medium.Due to compound plate in Explosion composite process under the effect of explosive energy according to this to substrate accelerated motion, and form certain bending angle, the effective combination between base, compound plate could be formed.And the intensity of NS312 alloy is relatively high, bending angle is formed more difficult in Explosion composite process, therefore static parameter will select larger explosive consumption, but facts have proved a large amount of jets that can produce in the process of Explosion composite larger area composite plate after adopting large dose, and these jets can be trapped in the land of composite plate, affect laminating rate and the shear strength of composite plate.For this reason, we take parallel method and arrange in conjunction with preset angle configuration, increase the passing away of jet.Larger support interval is reserved in edge region between NS312 alloy and steel, on NS312 alloy sheets, arranges thicker explosive, adopt preset angle configuration Explosion composite to produce the NS312/ steel composite board of about 10 ㎡.But the supporting gap that two ends are reserved is too high, cause laminating ripple thick, even do not fit, and the thinning problem such as too serious of NS312 plate, therefore adopt line detonation way, along the long side direction explosive that lay explosion velocity is higher continuously on NS312 alloy, to change the direction of jet motion, discharge to broadside, shorten the distance that jet moves in land, avoid jet to restrain in land.Edge region supports gap when base, compound plate installation supporting gap between NS312 alloy and steel is slightly larger than centre, and the jet so also for arriving edge provides more unobstructed passage, and two ends jet also can be avoided to pile up simultaneously.So adopt end low-angle installation and line to ignite the NS312/ steel composite board that method Explosion composite has produced about 25 ㎡.
The utility model beneficial effect is, NS312 alloy sheets compared with small size can make the edge of NS312 alloy sheets be unlikely to waste, be complete certified products composite plate as much as possible.The utility model achieves the Explosion composite of large-area NS312 alloy and steel, its performance such as laminating rate and shear strength all can meet the requirement of NB/T47002.2-2009 " pressure vessel Explosive Clad Steel Plate Part II: nickel-steel composite board " standard and ASME SA-265 " nickel and nickel-based alloy composite steel plates " standard, and the NS312 alloy clad steel plate of production can meet the needs of the industry development such as device fabrication and chemical industry dimensionally.
