Description
Technical field
The utility model is to produce the metallic explosive composite plate with the blast complex method, and it belongs to composite plate and makes the field.
Background technology
A kind of optimization alloy that the C-2000 alloy is developed as the range of application of expanding material, start from a conceptual idea, at nickel-chromium-molybdenum of improve having set up-be to add copper in the nickel-base alloy, come into the market since nineteen ninety-five, constantly obtain huge the affirming in market.Innovation technically not only makes alloy that the drag of aqueous corrosion is had raising, has also expanded the overall range of nickel-chromium-molybdenum family alloy.This new material can be resisted more corrosive chemical, comprises sulfuric acid, hydrochloric acid, hydrofluoric acid, simultaneously oxidisability and reproducibility environment is all had opposing energy energy.On engineering, C-2000 provides and has improved the great potential of producing, and when the place that is used in original Ni-Cr-Mo alloy, C-2000 can obtain equipment life more of a specified duration under same thickness, also can obtain higher safety coefficient under worse condition.There is not manufacturer production now but this material is domestic, full dependence import, price is very high, therefore do not reduce under the prerequisite of service life of equipment and performance in assurance, adopt C-2000 alloy-steel composite board, not only made full use of properties of materials---by the multiple layer of C-2000 alloy, by the basic unit of steel as bearing load as the contact corrosion medium, but also greatly reduce the cost of equipment, saved and used material.
The C-2000 alloy is a kind of nickel-base alloy by the HASTELLOY exploitation, along with the fast development of domestic chemical industry in recent years, growing field needs a large amount of C-2000 sheet alloys of import to manufacture various device or member, but because this material price costliness, domestic in recent years a lot of chemical industry producer proposes to research and produce the C-2000 composite plate.Form from present domestic equipment manufacturing development, the maximization of equipment is an inevitable development trend, therefore the required spiral-plate area of manufacturing equipment is also increasing, and this strength of materials density of working together is all higher, and these all give the compound very big difficulty of having brought of exploding.Find that by pre-stage test spiral-plate width of cloth size surpasses 20m
2The common appearance in Shi Zaiqi two ends is not fitted.Main cause is the accumulation of the residual jet in end, and the compound mechanism of exploding is the energy that utilizes explosive charge to produce, and promotes compound plate and produces the jet of high velocity jet to the substrate high velocity impact, thereby obtain interatomic metallurgical binding.Because blast process can produce jet, thereby self-cleaning is carried out on basic compound plate surface, make fresh metal combination, but a plate excessive back jet material is more and more, the jet material just can not be got rid of fully behind the two ends, part streams is just restrained in the land, causes the two ends poor bonding strength or even does not fit.The used similar composite of industries such as present domestic chemical industry substitutes with the austenite stainless steel composite board mostly, this has just shortened the service life of equipment, increased the waste of material, inconsistent with the development policies of national energy-saving consumption-reducing, also be unfavorable for the development of national industry.The large tracts of land C-2000 alloy-steel composite board that meets industry instructions for uses such as chemical industry is developed in therefore necessary autonomous innovation, and have great significance this service life for economical with materials, prolongation equipment.
The utility model content
The problem that the utility model solved is, as the energy, produces C-2000 alloy-steel composite board by the blast composite methods with explosive, to realize the requirement of production domesticization, satisfies the needs of industry development such as China's chemical industry.
The technical solution of the utility model is: C-2000 alloy/steel explosive clad plate constitutes composite plate by C-2000 alloy sheets and basic unit's steel plate.Promptly on basic unit's steel plate the blast compound C-2000 alloy sheets.C-2000 alloy sheets thickness is 2-5mm, and the thickness of steel substrate is 30-100mm.
On multiple layer C-2000 alloy sheets (4), should lay bigger dose, the mounting arrangements that is preset angle configuration by the explosion scene, finally make it to realize large-area continuous welding, satisfy the requirement of JB/T4748-2002 " pressure vessel with nickel and nickel-base alloy blast clad steel plate " standard and ASME SA-265 " nickel and nickel-base alloys clad steel plate " standard, the applying rate can reach more than 99%, minimum shear strength τ
b〉=210Mpa.
The blast of C-2000 alloy-steel composite board is compound to be C-2000 alloy sheets one deck as the contact corrosion medium, and steel plate is as other one deck of bearing load.Because compound plate according to this to substrate accelerated motion, and forms certain bending angle in the blast recombination process under the effect of explosive energy, could form the effective combination between basic, compound plate.And the intensity of C-2000 alloy is higher relatively, in the blast recombination process, form difficulty of bending angle, therefore static parameter will be selected bigger explosive consumption for use, but facts have proved and adopt behind the big dose at the compound a large amount of jets that can produce in than the process of large tracts of land composite plate of blast, and these jets can be trapped in the land of composite plate, influence the applying rate and the shear strength of composite plate.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 C-2000 alloy and steel zone, on the C-2000 alloy sheets, arranged thicker explosive, adopt the preset angle configuration compound 20m that produced that once explodes
2About C-2000 alloy-steel composite board.
The utility model has realized that the blast of large-area C-2000 alloy and steel is compound, performances such as its applying rate and shear strength all can satisfy the requirement of JB/T4748-2002 " pressure vessel with nickel and nickel-base alloy blast clad steel plate " standard and ASME SA-265 " nickel and nickel-base alloys clad steel plate " standard, and no matter the C-2000 alloy clad steel plate of production still is the needs that decay resistance all can satisfy industry developments such as device fabrication and chemical industry from mechanical property.
