Description
Technical field
The utility model belongs to composite plate manufacturing technology field, especially large tracts of land alloy-composite metal plate of producing with explosive method.
Background technology
NO8926 alloy (00Cr20Ni25Mo6.5N) is a kind of high-performance super austenitic stainless steel.This alloy is to pass through to increase Mo and N on the basis of 904L (00Cr20Ni25Mo4.5N), and Mo and the N amount that contains brings up to 6.5% and 0.2% respectively.NO8926 alloy ratio 904L has improved mechanical property and decay resistance significantly.The content that improves Mo and N has strengthened the ability of alloy anti-spot corrosion and crevice corrosion in the halide medium.This alloy has good resistance to spot corrosion under the halogen environment and crevice corrosion; Can resist the stress corrosion cracking that chlorion causes; The ability that good anti-homogeneous corrosion is arranged in multiple oxidation and reducing medium; The mechanical performance higher than 904L arranged; Than nickel content is that 18% similar austenitic stainless steel has higher alloy structure stability; Get permission by the pressure vessel of ASME standard manufacture operating temperature at-196～400 ℃.Therefore the application in chemical industry, petrochemical industry, salt manufacturing and environment-friendly engineering in recent years also increases gradually.But at home owing to be subjected to the restriction of the rare and price of material, application or less, therefore do not reduce under the prerequisite of service life of equipment and performance in assurance, adopt NO8926 alloy-steel composite board, not only made full use of properties of materials---by the multiple layer of NO8926 alloy as the contact corrosion medium, by the basic unit of steel, but also greatly reduce the cost of equipment, saved and used material as bearing load.
The NO8926 alloy is a kind of super austenitic stainless steel by Thyssen Krupp VDM company exploitation, domesticly still can't produce the NO8926 sheet alloy so far.Until in recent years because the needs of chemical industry development just begin import NO8926 sheet alloy, it is used for the making of pressure vessels for the chemical industry as anti-corrosion material, but consider that this imported material price is very expensive, a lot of producers of domestic chemical industry begin one's study in recent years and make composite plate with this material as multiple layer.It is higher with respect to general austenitic stainless steel to find that through Performance Detection the NO8926 alloy material contains the Mo amount, between 6.0～7.0%, thereby cause that the strength of materials is higher relatively, case hardness is bigger, and along with the fast development of domestic industry, the maximization of equipment is an inevitable development trend, therefore the required spiral-plate area of manufacturing equipment is also increasing, these are all given that blast is compound to have brought very big difficulty, has therefore hindered NO8926 the alloy composite plate application and the development of relevant industries such as chemical industry at home.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 NO8926 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.
Summary of the invention
The problem that the utility model solved is, proposes a kind of alloy-steel composite board, NO8926 alloy-steel composite board especially, can explosive as the energy, by the production of blast composite methods.
The technical solution of the utility model is: the steel alloy composite plate comprises that NO8926 alloy sheets 4 and steel substrate 6 constitute the thickness 3-6mm of NO8926 alloy sheets.The thickness of steel substrate is not limit, generally greater than 8mm, especially about 20mm.Steel substrate especially adopts the 16MnR steel plate, compound better effects if.
The utility model should be laid bigger dose on multiple layer NO8926 alloy sheets 4, 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 JB4733-1996 " pressure vessel blast stainless compound steel plate " standard and ASME SA-264 " stainless chrome-nickel steel clad steel plate, thin plate and steel band " standard, the applying rate can reach more than 99%, minimum shear strength τ
b〉=210Mpa.
The blast of NO8926 alloy-steel composite board is compound to be NO8926 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 energy-producing effect of explosive charge, could form the effective combination between basic, compound plate.And the intensity of NO8926 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 NO8926 alloy and steel zone, on the NO8926 alloy sheets, arranged thicker explosive, adopt the preset angle configuration compound 10m that produced that once explodes
2About NO8926 alloy-steel composite board.
The utility model has realized that the blast of large-area NO8926 alloy and steel is compound, performances such as its applying rate and shear strength all can satisfy JB4733-1996 " pressure vessel with blast stainless compound steel plate " standard and ASMESA-264 " stainless chrome-nickel steel clad steel plate, thin plate and steel band " standard code, and no matter the NO8926 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.
