Description

A kind of super thick cladding titanium steel explosive clad plate

Technical field

The utility model is to produce Explosive Composite Material with explosion welding method, it belongs to composite material manufacture neck Domain.Especially super thick cladding titanium steel explosive clad plate.

Background technology

Explosion composite method production composite material have been widely used for oil, chemical industry, shipbuilding, electronics, electric power, metallurgy, The industrial circles such as machinery, aerospace, atomic energy.Develop now with equipment manufacturing technology, to the quality of composite products It is required that higher and higher, the requirement especially for the titanium/steel composite board of cladding super thick is higher and higher, and composite plate cannot have uncombined Region exists, this will increase composite plate production difficulty.So point initiation cannot be placed in the range of effective coverage, by point initiation It is placed on that edges of boards genesis is quick-fried, must so increases the dosage of material.

Especially for the thicker composite plate of cladding, the dynamic bending angle of moment diminishes when Explosion composite detonates, and causes thunder The uncombined region in area under control domain can bigger.It is not associated with not reprocessing by repair welding again between titanium plate and steel plate, main cause is During the direct melting welding of titanium and steel plate, the iron-holder in weld seam can exceed the solubility range in titanium, and brittleness is easily formed in weld seam Intermetallic compound.Go out metal compound beyond the region of objective existence, also have the low-melting-point eutectic that intermetallic compound is formed in weld seam.These phases Hardness reach HV600, some even arrives HV800~1050, causes weld seam embrittlement, form crackle, TiFe types in cooling procedure And the brittlement phase such as TiC can cause weld cracking.So influence whether composite plate qualification area, the loss to titanium plate will also increase.

Utility model content

The utility model aim is to overcome the shortcomings of the above, there is provided a kind of new explosion harden structure, obtains the cladding of qualification The titanium of super thick/steel pipe plate.

The technical solution of the utility model is：Super thick cladding titanium steel explosive clad plate, complex laminate is titanium plate, in Substrate sheet One block of steel plate of edge external welding, the steel plate of welding is consistent with Substrate sheet material to be composite, and with the upper surface of Substrate sheet Faying face i.e. to be exploded is concordant, Substrate sheet edge avoid because materials variances cause propagation of explosion uneven situations such as.The steel plate of welding Thickness be 3-5cm, width 10-15cm.The thickness of Substrate sheet is 10-25cm.

Supported between super thick cladding titanium steel explosive clad plate cladding titanium and Substrate sheet using certain interval, pass through parallel method Mounting arrangements, be finally allowed to realize the continuous welding of large area, meet《NB/T47002.3-2009B1 pressure vessels explode Weld composite plate》Standard and the ASTM B898 vivaciously requirements with refractory metal explosive clad plate standard, pass through Explosion composite steel plate Fitting rate reaches more than 100% after (slab) is compound, minimum shear strength τ_b>=140Mpa, product qualification rate reach 99% with On.

Beneficial effect：Solve the quality problems of the titanium/steel composite board of cladding super thick (more than 10cm)：Weldering on the outside of Substrate sheet One block of steel plate 5 is connect, this steel plate is concordant with treating Explosion composite face, is supported between cladding titanium layer 3 and Substrate sheet 6 using certain interval 4, by the mounting arrangements of parallel method, emulsion 1 is covered above titanium plate, detonator 2 is placed on the steel plate welded, is exploded Chemical reaction is just propagated forward through acceleration after a while with detonation rate on compound plate.With the propulsion and explosion of detonation wave The drastically expansion of product, the chemical energy of explosive are largely converted into the detonation wave and explosion product of high-speed motion.Then this is dynamic A part for energy passes to compound plate, so as to promote compound plate that the first collision occurs on the steel plate welded to substrate high-speed motion Contact, compound plate and substrate are hit successively on the contact point immediately, reach continuous welding, make penetrating for explosive welding moment generation Stream ejects faying face.The utility model solves cladding using explosive as the energy, by the way that point initiation is drawn outside effective coverage The method production composite plate of the clad tubesheet detonator zone of super thick, improves the qualification rate of product, reduces the consumption of rare precious metal, meet The needs of China's development of chemical industry.

Embodiment

The embodiment of the utility model is specifically described below.

In one steel plate of basic unit's forging external welding, then the technique for solving the titanium/steel composite board detonator zone of cladding super thick is Detonate outside steel plate, (cladding titanium plate thickness is 12mm) as shown in Figure 1.Main body explosive major parameter：Explosion velocity is up to 1800 ~2200m/s, density (0.65~0.85) g/ ㎝³, brisance (lead block compressed value) about 6~10mm；After Explosion composite, then through overheat The techniques such as processing, smoothing, trimming；Through ultrasound examination, it is 0 that region is not associated between slab and titanium plate, and on the steel plate welded Face can cut or separately use there are the uncombined region of 70mm.But it can guarantee that the titanium/steel composite board of super thick is all up to standard.So Operation is to ensure that the quality of product reduces the consumption of rare precious metal titanium, the performance such as its fitting rate of product and shear strength again It can meet《NB/T47002.3-2009 B1 pressure vessel Explosive Welding Composite Plates》Standard and ASTM B898 vivaciously with difficulty The requirement of molten metal explosion composite board standard, and its explosive forming qualification rate also reaches 99%, no matter from mechanical property Or corrosion resistance can meet the needs of device fabrication and development of chemical industry.The utility model eliminates Explosion composite Titanium/uncombined the problem in steel pipe plate detonator region.
