Abstract
One-ton brass steel explosion clad pipe plate, forms by the blast of one-ton brass and steel plate is compound, and wherein one-ton brass and surface of steel plate are evenly opened the plate hole of diameter 6-10cm, and wherein the thickness of one-ton brass and steel plate is respectively 2-3mm and 6-8mm.No matter the utility model one-ton brass-steel explosive clad plate all can meet the needs of heat exchanger anticorrosion equipment manufacture development from mechanical property or decay resistance.
Description
Technical field
The utility model is to produce metallic explosive clad tubesheet with explosive welding complex method, and it belongs to composite plate and manufactures field.
Background technology
HSn70-1 be take the complex brass that tin is main adding elements.Tin can suppress dezincification of brass, improves the corrosion resistance of brass.One-ton brass is all anti-corrosion in fresh water and seawater, in the world the general term of broad sense " admirality brass ".In the αsolidsolution of zincification, the solubility of tin is very little, but occurs β phase time when zinc content is increased to, and the solubility of tin increases.A small amount of tin can be dissolved in alpha brass, puies forward heavy alloyed intensity and hardness.HSn70-1 can bear the processing of heat, cold pressure preferably, and the tin content of HSn70-1 is in 1% left and right, stanniferously too much can fall low-alloyed plasticity.HSn70-1 has high corrosion resistance in atmosphere, steam, oils and seawater, and there is good mechanical property, machinability still can, easily welding and fine weldering, cold-forming property is good, hot bending, and hot extrude performance is medium, and there are good heat conduction and corrosion resisting property, are widely used in heat exchanger condenser pipe material in Coastal Power Plant, naval vessel.The metallic explosive composite plate pipe that utilizes one-ton brass performance is for heat exchanger corrosion-resistant vitals.
At present domestic pressure container and above boats and ships HSn70-1-steel composite board used mostly rely on from external import, not only expensive, and the delivery cycle is very long, be unfavorable for like this applying of China HSn70-1-steel composite board equipment, be more unfavorable for the development of national industry.Therefore must autonomous innovation, develop the manufacture craft of high-performance HSn70-1-steel composite board, this to reducing device fabrication cost, shorten the device fabrication cycle and will play significance.
Utility model content
The problem that the utility model solves is, using explosive as the energy, by the method that explosive welding is compound, produce one-ton brass (QSn4-4-2.5)-steel pipe plate, be provided for the important sheet material of heat exchanger corrosion-resistant and save cost, metallic explosive composite plate pipe is the requirement that realizes production domesticization, meets the needs of China's steam boiler and seagoing vessel part heat exchanger applications.
The technical solution of the utility model is: one-ton brass steel explosion clad pipe plate, it is characterized in that forming by the blast of one-ton brass and steel plate is compound, wherein one-ton brass and surface of steel plate are evenly opened the plate hole of diameter 6-10cm, and wherein the thickness of one-ton brass and steel plate is respectively 2-3mm and 6-8mm.
Between multiple layer HSn70-1 (4) and Substrate sheet (6), adopt certain interval, by the mounting arrangements of parallel method, finally make it to realize large-area continuous welding, meet Explosive Welding Composite Plates the 4th part for < < NB/T47002-2009 pressure vessel: copper-steel composite board > > standard-required, by exploding, compoundly rear fire point is carried out can making laminating rate reach more than 100% after repair welding minimum shear strength τ
b>=140Mpa.
The blast of HSn70-1-steel composite board is compound is the one deck using HSn70-1 plate as contact corrosion medium, and steel plate is as other one deck of bearing load.When be placed in explosive on compound plate by cap sensitive after, the blast chemical reaction of explosive is just propagated forward on compound plate with detonation rate through acceleration after a while.Along with the propelling of detonation wave and the sharply expansion of explosion product, the chemical energy major part of explosive is transformed into detonation wave and the explosion product of high-speed motion.A part for this kinetic energy passes to compound plate subsequently, thereby promotes compound plate to substrate high-speed motion, and forms certain bending angle, and compound plate and substrate clash into successively immediately on contact point, could form the effective combination between base, compound plate.
The utility model has been realized the explosive clad plate of HSn70-1-steel, the performances such as its laminating rate and shear strength all can meet Explosive Welding Composite Plates the 4th part for < < NB/T47002-2009 pressure vessel: the requirement of copper-steel composite board > > standard, the HSn70-1-steel composite board of production is no matter from mechanical property or decay resistance all can meet the needs of the manufacture of heat exchanger anticorrosion equipment and development of chemical industry.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that the utility model blast is installed,
Fig. 2 is the utility model Facad structure schematic diagram.
The specific embodiment
Illustrate embodiment of the present utility model below.1. detonator 2. explosive 3. protective layer 4.HSn70-1 5. back-up block 6.Q345R 7. bases in figure.
The blast of one-ton brass (typical HSn70-1)-steel plate is compound is above HSn70-1 being placed on while installing at the scene, and steel plate, as a laminar substrate below, is supporting gap between two plates, clearance height 20mm.In addition, the compound dose that explodes will suitably increase, and for fear of the compound plate face of burning in blast recombination process, protective layer also will be thickeied.HSn70-1 tube plate thickness is δ 8mm, plate width size is 6000mm * 2000mm (L * W), substrate thickness is δ 30mm Q345R steel plate tube sheet, plate width is of a size of 6000mm * 2000mm (L * W), and the main body explosive of selecting is powdery emulsifying explosive, and the parameter of powdery emulsifying explosive is: explosion velocity>=3200m/s, quick-fried heat>=4000KJ/Kg, 2654 ℃ of quick-fried temperature, detonation pressure 519Mpa, density (0.95～1.25) g/ ㎝
3, brisance (lead block compressed value)>=15mm.Rear distribution explosive is protected on HSn70-1 plate surface, and explosive payload is 2.89g/ ㎝
2.Flashpoint is placed on HSn70-1 compound plate center, i.e. two cornerwise intersection points, and lay high explosion velocity straight dynamite along center line, and edge explosive height outline is higher than mid portion, and the multiple layer in edge, aspect is sheared.As Fig. 1.Explode compound after, after heat treatment, leveling, by Explosive Welding Composite Plates the 4th part for < < NB/T47002-2009 pressure vessel: copper-steel composite board > > standard detects laminating rate and shear strength, laminating rate reaches 100%, shear strength τ
b>=140Mpa.The utility model has been taken into account respectively the feature that corrosion resistance that HSn70-1 is good and anti-wear performance and armor plate strength are good.And greatly reduce the manufacturing expense of equipment.
