GR1 Titanium Clad Steel Phaj Rau Siab

Nrog rau txoj kev loj hlob ntawm domestic siab hlab ntsha manufacturing technology,GR1 titanium clad steel phaj rau siabyog nce siv nyob rau hauv kev tsim cov corrosion-resistant siab hlab ntsha vim lawv cov kev ua tau zoo thiab kev lag luam. Txawm li cas los xij, vim qhov tshwj xeeb ntawm nws cov ntaub ntawv, feem ntau cov tuam txhab tsim khoom hauv tsev tsis muaj kev tsim khoom, yog li kev saib xyuas thiab kev tshuaj xyuas ntawm nws cov txheej txheem tsim khoom yuav tsum tau them nyiaj tshwj xeeb. Tus kws sau ntawv ntseeg tias kev saib xyuas kev tsim khoom thiab kev tshuaj xyuas yuav tsum tsom rau kev ntxiv dag zog rau kev tswj cov khoom siv, kev tswj cov txheej txheem vuam thiab lwm yam kev sib txuas kom ntseeg tau tias kev ua haujlwm ruaj ntseg ntawm titanium clad phaj siab hlab ntsha hauv cov txheej txheem siv yav tom ntej.

Vim tias titanium nws tus kheej muaj cov yam ntxwv sib txawv ntawm cov pa roj carbon zoo tib yam thiab cov hlau tsis muaj steel, piv txwv li, lub melting point ntawm titanium yog 1668 degree, uas siab dua lwm yam hlau (xws li hlau, stainless hlau, txhuas, tooj liab, thiab lwm yam): muaj ntshiab titanium thiab feem ntau titanium alloys tuaj yeem welded lawv tus kheej lossis ib leeg, tab sis tsis tuaj yeem fused nrog lwm cov hlau, piv txwv li, solubility ntawm hlau hauv titanium tsuas yog 0 05% ~ 0.1 feem pua ​​, thiab hlau uas tshaj cov solubility ua nkig titanized hlau theem nyob rau hauv titanium, ua rau loj embrittlement ntawm titanium, Yog li ntawd, titanium tsis tuaj yeem fused nrog hlau, thiab txawm tias hlau zoo tsis pub nkag mus rau hauv titanium vuam. Lub zog tensile thiab lwm yam khoom siv ntawm kev lag luam ntshiab titanium hloov nrog kub ntau dua li cov pa roj carbon zoo tib yam thiab cov hlau tsis tshua muaj hlau; Tom qab qhov kub thiab txias, lub zog tensile thiab lub zog ntawm lub thawv txo qis heev. Thaum txog 250 ~ 300 degree, lub zog tensile thiab lub zog tawm los yog li ib nrab ntawm qhov kub thiab txias, thiab lwm yam, yog li lub zog thiab cov qauv tsim ntawm lub thawv yog qhov nyuaj thiab nyuaj dua li cov qauv tsim.

Kev xaiv lub taub hau rau lub taub hau ntawm cov hlab ntsha siab, cov taub hau kheej kheej feem ntau yog siv.

Vim hais tias lub plhaub kheej kheej muaj tib lub vojvoog ntawm curvature nyob txhua qhov chaw, nws daim nyias nyias qhov kev ntxhov siab yog sib npaug ntawm lub plhaub kheej kheej thiab qhov loj yog sib npaug, thiab qhov kev ntxhov siab yog qhov zoo tshaj plaws. Txawm li cas los xij, Qincai muaj lub zog muaj zog, lub zog loj deformation thiab qhov loj ntawm qhov sib piv, qhov nqaim ntawm cov yas deformation, qhov loj ntawm qhov tawg tawm lub zog rau elastic modulus thaum ua haujlwm txias, qhov nyiaj rov qab loj dua thaum ua haujlwm txias, Tsawg tus txheeb ze elongation thiab tus txheeb ze cheeb tsam shrinkage, thiab ib tug loj nyiam rau txias ua hauj lwm hardening, uas yog unfavorable rau siab ua hauj lwm deformation. Tsis tas li ntawd, rau GR1 Titanium Clad Steel Phaj rau Siab.

Raws li cov thermal expansion coefficient thiab elastic modulus ntawm titanium thiab hlau sib txawv, qhov sib txawv thermal deformation ntawm lawv yuav nce nrog qhov kub thiab txias, uas yuav ua rau muaj kev ntxhov siab ntau dua ntawm qhov sib txuas thiab ua rau titanium puas txheej txheej.

Nta ntawm titanium-clad phaj vuam khoom

Lub cladding ntawm stainless hlau clad phaj yog kev koom ua ke nrog lub hauv paus txheej, yog li cov welded sib koom ua ke ntawm stainless hlau clad phaj yuav dais lub load ua ke nrog lub hauv paus txheej. Txawm li cas los xij, txheej clad ntawm titanium composite phaj tsis tuaj yeem ua tiav nrog txheej txheej, yog li cov txheej txheem titanium tsuas yog txhawb nqa los ntawm kev sib koom ua ke ntawm nws tus kheej nyias txheej. Tsis tas li ntawd, qhov nruab nrab linear expansion coefficient ntawm titanium yog li 8.5 × 10-6 / degree .

Dej, roj, oxide thiab lwm yam kuab paug hauv vuam yuav ua rau qhov zoo ntawm titanium vuam pob qij txha. Yog li ntawd, lub vuam hlau, zawj thiab nws cov cheeb tsam ib puag ncig yuav tsum tau ntxuav. Qhov kev tu xyuas no yog nruj dua li qhov yuav tsum tau ua rau kev huv ntawm cov hlau thiab txhuas vuam. Qhov saum npoo polished los ntawm kev sib tsoo log thiab qhov chaw nrog oxide zaj duab xis nyob rau saum npoo yuav tsum tau muab txhuam nrog scraper kom ntseeg tau tias qhov zoo ntawm qhov sib koom ua ke. Lub chaw ua haujlwm txias txias yuav tsum raug cais tawm ntawm lwm qhov chaw tsim khoom thiab cov khoom siv, thiab muaj cov chaw tiv thaiv hlau lossis lwm qhov chaw muaj kuab paug hlau.

Oxygen, hydrogen, nitrogen, carbon thiab hlau yog interstitial ntsiab ntawm titanium, uas yuav yaj nyob rau hauv titanium los tsim interstitial khoom tov. Thaum cov ntsiab lus ntawm cov ntsiab lus saum toj no tshaj nws cov solubility hauv titanium, lawv yuav tsim ntau lub tebchaw nrog titanium, ua rau titanium brittle, nce lub zog thiab hardness, thiab txo cov plasticity. Cov txheej txheem no yog irreversible. Titanium weld belongs rau casting qauv, uas inevitably muaj qhov tsis xws luag xws li porosity, segregation, porosity, coarse grain (txawm tias nyob rau hauv qhov tso cai qhov tsis xws luag ntawm qhov tsis pom kev), thiab siv tom qab vuam. Txawm hais tias cov txheej txheem vuam raug tiv thaiv zoo, impurities yuav ib txwm nce tab sis tsis txo qis. Yog hais tias lub titanium vuam hlau nrog tib impurity cov ntsiab lus raws li lub hauv paus hlau yog siv rau vuam, lub plasticity ntawm titanium weld yog qis dua li ntawm lub hauv paus hlau, uas yog heev yooj yim ua rau lub titanium weld tawg nyob rau hauv kev siv ntawm titanium. ntim thiab txawm nyob rau hauv kev tsim khoom. Tib txoj hauv kev ua tau zoo los txhim kho lub vuam yas yog txo cov ntsiab lus impurity hauv vuam hlau. Yog li ntawd, kev xaiv ntawm titanium vuam hlau yog ib qho tseem ceeb heev. Lub vuam hlau nyob rau hauv Daim Ntawv Ntxiv D ntawm JB/T4745-2002 Titanium Vuam Vessel tuaj yeem xaiv tau, thiab cov khoom siv vuam hlau uas tsim nyog nrog cov ntsiab lus qis dua ntawm cov hlau hauv paus kuj tuaj yeem xaiv.
