Zirconium Titanium Hlau Composite Phaj

1. Khoom Taw Qhia

Zirconium titanium steel composite plate is a three-layer composite plate with a transition layer titanium plate between the zirconium plate layer and base steel plate. Zirconium titanium steel clad plate is composed of zirconium plate and steel plate by explosive composite technology. Zirconium steel composite plate pressure vessel combines the advantages of zirconium and steel, which not only meets the requirements of special corrosion resistance but also greatly reduces the manufacturing cost.

3. Daim ntawv thov teb

Aerospace - ZrO₂muaj qhov melting point ntawm 2700 degree thiab muaj zog siab -kub tsis kam, xws li ntog tawm ntawm cov vuas ntawm lub dav hlau;

Nuclear reactor - zirconium rau reactor roj pas nrig cladding, zoo tiv thaiv nuclear tawg thiab txhua yam khoom;

Kev lag luam tshuaj lom neeg -- xws li lub cev qhuav dej ntauwd nyob rau hauv methanol carbonylation acetic acid txheej txheem chav tsev, thiab lub dehydration ntauwd yog zirconium composite phaj khoom;

 

4. Lub cev muaj zog thiab microstructure ntawmZirconium

1) Zirconium yog cov nyiaj tsis tshua muaj hlau nrog lub melting point ntawm 1850 degree thiab qhov ntom ntawm 6.5g / cm3.

2) Kev ua haujlwm siab, tuaj yeem hlawv hauv kev sib cuag nrog hluav taws qhib.

3) 862 degree yog isomorphic thiab heteromorphic hloov pauv kub ntawm zirconium. Hauv qab 862 degree, nws yog tuab hexagonal lattice thiab lub cev -centered cubic lattice ntawm qhov kub thiab txias.

4) Yog li ntawd, zirconium li hlau rau cov hlab ntsha siab muaj qhov ntom ntom hexagonal lattice thiab cov yas tsis zoo. Yog li, cov ntaub ntawv zirconium feem ntau yog ua tiav kub, uas tuaj yeem txhim kho cov yas thiab molding kev ua tau zoo ntawm cov ntaub ntawv. Nws yog qhov zoo dua los tswj cov molding kub ntawm 500-600 degree.

 

5. Vim tias qee cov ntsiab lus muaj cov solubility tsawg nyob rau hauv qhov ze - ntim hexagonal lattice thiab yooj yim rau cov qauv nkig, zirconium yuav tsum tsis txhob ncaj qha welded nrog hlau, txhuas, tooj liab, thiab npib tsib xee.

6. Cov kev cai thiab kev xaiv cov khoom siv lub tswv yim ntawm cov khoom siv zirconium

Piv nrog rau qhov tso cai rau kev ntxhov siab ntawm zirconium, lub siab {{0}}} cov kabmob muaj peev xwm ntawm zirconium raug txwv ntawm qhov kub thiab txias. Cov khoom siv zirconium yog kim. Tus nqi ntawm imported 702 zirconium yog lab / tuj, thiab cov zirconium hauv tsev yog ntau pua txhiab yuan / tuj. Txhawm rau kom ua tau raws li qhov kev tiv thaiv corrosion thiab lub siab muaj peev xwm thiab ua kom muaj kev lag luam tsim nyog, zirconium puas phaj feem ntau xaiv rau cov khoom siv zirconium loj. Feem ntau, Zr-1 lossis ZR-3 yog siv rau cladding. Bonding tus nqi: zirconium composite steel phaj, lub zog shear ntawm qhov chaw sib txuas yuav tsum tsis pub tsawg tshaj 140MPa, thiab thaj tsam sib txuas tus nqi yuav tsum yog chav A, Ntau dua lossis sib npaug li 99 feem pua. Yog tias yuav tsum muaj kev sib raug zoo siab dua, kev lag luam ntshiab titanium phaj tuaj yeem siv los ua qhov nruab nrab interlayer ntawm cov phaj sib xyaw. Thaum tshav kub kub kho lub xeev: cov ntaub ntawv zirconium (phaj, raj, forgings, thiab lwm yam) siv rau zirconium siab hlab ntsha yuav tsum recrystallized thiab annealed. Manufacturing: tiv thaiv hlau ion kuab paug thiab galvanic corrosion. Cov nplaim hluav taws kub kho tom qab vuam: kub 510-620 degree, thickness Tsawg dua lossis sib npaug li 25 hli, thermal rwb thaiv tsev Ntau dua lossis sib npaug rau 1H; Lub thickness nce thiab rwb thaiv tsev yog ntev. Kev kuaj ultrasonic: zirconium daim hlau rau cov kabmob siab nrog lub thickness ntawm ntau tshaj 6 hli yuav tsum raug kuaj xyuas ultrasonic ib los ntawm ib qho. Lub phaj thickness yog 6-25 hli, qib A1 yog qhov tau txais (inch ntawm ib lub qhov tsis sib txuas Tsawg dua lossis sib npaug li 1.2 hli); Lub phaj tuab yog 25-50mm, chav kawm A yog qhov siv tau (inch ntawm ib lub qhov tsis sib txuas Tsawg dua lossis sib npaug li 2 hli). Kev ntsuas siab: cov kav dej zirconium yuav tsum raug rau kev sim hydraulic (pneumatic) ib qho los ntawm ib qho. Qhov tsawg kawg nkaus ntsuas siab P=2st / D, s yog qhov tso cai fiber ntau kev nyuaj siab, thiab qhov tseem ceeb ntawm ZR-3 thiab zr-5 yog lub zog tawm los RP0 hauv cov lus saum toj no raws li 2, qhov ntsuas siab P yuav tsum tsis siab tshaj 17.2 Mpa. Pickling thiab passivation: Tom qab kev sim siab, kev kho mob thiab kev kho mob yuav tsum tau nqa tawm ntawm cov khoom siv zirconium. Kev ntsuam xyuas cov dej xau: cov hlab ntsha sib xyaw lossis cov hlab ntsha siab uas muaj cov khoom siv zirconium yuav tsum raug kuaj xyuas (xav tias lawv feem ntau yog cov xov xwm corrosive heev). Kev kuaj pom cov dej xau: feem ntau, cov qauv kuaj pom yuav tsum tau teeb tsa nruab nrab ntawm cov txheej txheej hauv ob sab phlu thiab cov txheej txheem ntawm zirconium lined siab nkoj thiab nruab nrab ntawm cov cladding vuam sib koom thiab lub hauv paus txheej ntawm zirconium clad phaj siab nkoj.

7. Peb qhov zoo dua

Raws li ib tugzirconium titanium hlau composite phaj chaw tsim tshuaj paus, peb lub tuam txhab muaj cov txheej txheem ua tiav ntawm cov phaj sib xyaw: cov khoom sib xyaw ua ke thiab tawg tawg. Tshwj xeeb, tawg dov yog ib qho ntawm ob peb lub lag luam hauv Suav teb uas tuaj yeem paub txog loj - nplai ntau lawm ntawm cov phaj sib xyaw. Nws tuaj yeem tsim cov phaj sib xyaw nrog cov thicknesses sib txawv, sib txawv proportions, txawv specifications, txawv cov kev xav tau, thiab ntau yam los ntawm cov txheej txheem ntau lawm.
