Description
Technical field
The utility model belongs to explosive welding composite metal plate manufacturing field, is related specifically to a kind of wide cut titanium steel composite board
Explosion cladding structure.
Background technique
Titanium/steel composite board has good corrosion resisting property and cost performance, in chemical industry, petroleum, steam turbine condenser, electric power etc.
Industry has a wide range of applications market.With the high speed development of chemical industry, it will be apparent that trend be chemical plant installations large size
Change, complication and diversification, therefore the requirement to titanium steel composite material size is also increasing.1.5m is greater than for width breadth
Titanium steel composite board to be spelled before explosive welding titanium steel composite material due to being limited by existing market for delivery gauge
It connects, to meet the requirement of different specification size.But since splicing welding joint metal is as cast condition, mechanical property is than matrix titanium
It is weak, usually crack or be broken under Explosion Loading, to this phenomenon document " explosive welding and explosive composite material,
P157 " carry out analytic demonstration and experiment.To avoid titanium weld seam from being subjected to the effect of detonation wave load, document " explosive welding and quick-fried
Fried composite material, P167 " describe a kind of method, the titanium plate for needing welding for two pieces separately or concurrently Explosion composite in same
On substrate, two pieces of titanium plates are welded again after Explosion composite, avoid titanium plate weld seam in this way under the effect of detonation wave load
The crackle of generation, problem is that such explosive welding mode will form and not be bonded defect under titanium plate weld seam, although for low
The conventional equipments such as pressure vessel allow using but such defect is also not allow for tube sheet and head plate.Although in technique
1.5m, weldless titanium steel composite board comparative maturity are less than to explosive welding width, but are more than 1.5m for explosive welding width,
Titanium steel composite board with weld seam, technically there are also many problems to be solved.
Utility model content
The purpose of this utility model is to provide a kind of width protected position while welding, overcome commissure crackle and breakage problem
Width titanium steel composite board explosion cladding structure overcomes weld seam present in existing wide cut titanium steel composite board explosive welding and usually produces
Welded after raw crackle or fracture and explosion under titanium plate weld seam the disadvantages of not being bonded defect.
To achieve the goals above, the technical solution of the utility model is as follows: a kind of wide cut titanium steel composite board Explosion composite
Structure, the composite construction include the basal plate being placed on ground and titanium complex laminate, and titanium complex laminate is several with argon arc welding or to wait
The titanium plate of ion weldering splicing is to pass through polishing and burnishing machine rubbing down to the weld seam concordant with base material between titanium plate two-by-two；Titanium complex laminate is located at
Support chip is arranged above the basal plate, between titanium complex laminate and basal plate to separate, explosive is arranged in the top of titanium complex laminate, fries
Electric cap is arranged in the top of medicine；Arrange that buffer bar, buffer bar separate weld seam and explosive above the weld seam, the width of buffer bar
It is 2 ~ 3 times of weld width.
The buffer bar material is titanium plate or stainless steel plate, and width covers titanium plate weld dimensions, is 20 ~ 40mm,
With a thickness of 1 ~ 2mm, length is equal to fusion length, and the center line of buffer bar is aligned with the center line of weld seam.
The support chip material is V-type titanium item, and with a thickness of 0.2 ~ 0.3mm, clearance height is 6 ~ 10mm, is divided between laying
200 ~ 300mm, support chip is far from titanium plate weld dimensions.
Basal plate material is Q245R or Q345R, is laid on sandy soil ground.
The explosive uses powdery emulsifying explosive, and addition perlite adjustment explosion velocity of explosive is 2000 ~ 2500m/s, explosive
It is laid on titanium complex laminate and weld seam buffer bar, lays explosive with a thickness of 30 ~ 40mm.
A kind of method of wide cut titanium steel composite board explosion cladding structure preparation wide cut titanium steel composite board, this method includes following
Step:
The argon arc welding of the titanium plate of monolithic or plasma welding are welded into titanium complex laminate by step 01), and weld seam is two-sided using throwing
Grinding machine rubbing down is extremely concordant with titanium plate base material, using the face to be combined of sized flap wheel rubbing down titanium complex laminate, it is made to expose fresh metal
Level；Buffer bar is pasted on a face weld seam of contact explosive using bonding agent；
Step 02) sequentially consists of basal plate, titanium in sandy soil ground over-assemble wide cut titanium steel plate explosion cladding structure
Complex laminate and explosive lay support chip between basal plate and titanium complex laminate, and detonating primer is arranged in the upper end of explosive；
Step 03) detonating primer, makes explosive detonation, titanium complex laminate be pushed to basal plate obtain wide format titanium steel it is compound
Plate, the impacting with high pressure load that explosive detonation generates pass to titanium weld seam by buffer bar, and moment impact load is mostly by buffer bar
It absorbs, titanium weld seam does not bear high temperature, the high pressure load that detonation load generates directly, and the remaining impact energy acted on weld seam rises
To the purpose for pushing weld seam to accelerate.
The spliced weld seam of titanium plate, which is first heat-treated, then carries out explosive welding.
The good effect that the technical solution of the utility model generates is as follows: the utility model is spelled using buffer bar covering titanium plate
The position of welding seam, when being to solve explosive charge in conventional production process, the high temperature and pressure impact wave load generated is straight
It connects and acts on position while welding, molded weld seam immediate set is forced, and generate high velocity impact with substrate, due to the weld seam of splicing
For as cast condition, tension and extension strength are all low compared with base material, thus cannot bear such strong shock loading and deformation and split
Line or fracture, especially splicing titanium plate weld seam are lateral detonation wave, due to the shock loading that weld seam is born be it is lateral,
The probability that weld seam is cracked or is broken is higher, even if carrying out Overheating Treatment, this bead crack defect after the splicing of titanium plate weld seam
Or can frequent occurrence, it is bad or completely not often to will appear bond quality for and the region that titanium weld seam is cracked or is broken
Fitting generates huge economic loss so that wide cut titanium steel composite board quality be caused to reduce or scrap phenomenon.The utility model is adopted
With on titanium plate weld seam be laid with buffer bar method, effectively avoid detonation load from directly acting on titanium plate weld seam, thus reduce or
Prevent a possibility that crackle or fracture occur for titanium plate weld seam.
