Peb siv cov ncuav qab zib los txhim kho koj qhov kev paub. Los ntawm kev txuas ntxiv mus saib lub xaib no, koj pom zoo rau peb siv cov ncuav qab zib. Cov Lus Qhia Ntxiv.
Los ntawm lawv tus kheej xwm, cov khoom siv rau kev siv kho mob yuav tsum ua tau raws li cov qauv tsim thiab kev tsim khoom nruj heev. Hauv lub ntiaj teb uas muaj kev sib hais plaub thiab kev ua pauj rau kev raug mob lossis kev puas tsuaj los ntawm kev ua yuam kev kho mob, txhua yam uas kov lossis raug phais cog rau hauv tib neeg lub cev yuav tsum ua haujlwm raws li tau npaj tseg thiab yuav tsum tsis txhob ua tsis tiav.
Cov txheej txheem ntawm kev tsim thiab tsim cov khoom siv kho mob yog ib qho ntawm cov teeb meem nyuaj tshaj plaws hauv kev tshawb fawb txog cov ntaub ntawv thiab kev tsim kho uas yuav tsum tau daws hauv kev lag luam kho mob. Nrog rau ntau yam kev siv, cov khoom siv kho mob muaj ntau yam duab thiab qhov loj me los ua ntau yam haujlwm, yog li cov kws tshawb fawb thiab cov engineers siv ntau yam khoom siv los ua kom tau raws li cov kev cai tsim qauv nruj tshaj plaws.
Cov hlau tsis xeb yog ib qho ntawm cov ntaub ntawv siv ntau tshaj plaws hauv kev tsim khoom siv kho mob, tshwj xeeb tshaj yog 304 stainless hlau.
304 stainless hlau yog ib qho ntawm cov khoom siv zoo tshaj plaws rau kev tsim cov khoom siv kho mob rau ntau yam kev siv. Qhov tseeb, nws yog cov hlau stainless hlau uas siv ntau tshaj plaws hauv ntiaj teb niaj hnub no. Tsis muaj lwm hom hlau stainless hlau uas muaj ntau yam duab, tiav thiab siv tau zoo li no. Cov yam ntxwv ntawm 304 stainless hlau muab cov khoom siv tshwj xeeb ntawm tus nqi sib tw, ua rau lawv yog qhov kev xaiv zoo rau cov lus qhia txog cov khoom siv kho mob.
Kev tiv taus corrosion siab thiab cov pa roj carbon tsawg yog cov yam tseem ceeb uas ua rau 304 stainless hlau zoo dua rau kev siv kho mob dua li lwm cov qib ntawm stainless hlau. Cov khoom siv kho mob tsis ua tshuaj lom neeg nrog cov ntaub so ntswg ntawm lub cev, cov neeg sawv cev ntxuav siv los ua kom tsis muaj kab mob, thiab qhov nyuaj, rov ua dua thiab tsim kua muag uas ntau cov khoom siv kho mob raug, txhais tau tias Hom 304 stainless hlau yog cov khoom siv zoo tagnrho rau tsev kho mob, phais, thiab kev siv kho mob. daim ntawv thov., ntawm lwm tus.
304 stainless hlau tsis yog tsuas yog muaj zog xwb tab sis kuj yooj yim heev rau kev ua thiab tuaj yeem rub tob yam tsis muaj annealing, ua rau 304 zoo tagnrho rau kev ua cov tais, dab dej, lauj kaub thiab ntau yam thawv kho mob sib txawv thiab cov khoom khoob.
Kuj tseem muaj ntau hom sib txawv ntawm 304 stainless hlau nrog cov khoom siv zoo dua rau cov ntawv thov tshwj xeeb, xws li cov khoom siv hnyav uas tsis muaj carbon ntau ntawm 304L qhov twg xav tau cov vuam muaj zog. Cov khoom siv kho mob siv tau 304L qhov twg vuam yuav tsum tiv taus ntau qhov kev co, kev ntxhov siab tas mus li thiab / lossis kev hloov pauv, thiab lwm yam. 304L stainless hlau kuj yog cov hlau kub qis, uas txhais tau tias nws tuaj yeem siv rau hauv cov ntawv thov uas cov khoom yuav tsum ua haujlwm ntawm qhov kub qis heev. Rau cov chaw muaj xeb heev, 304L kuj muab kev tiv thaiv zoo dua rau kev xeb intergranular dua li cov qib stainless hlau sib piv.
Qhov kev sib xyaw ua ke ntawm lub zog qis thiab lub peev xwm loj elongation txhais tau tias Hom 304 stainless hlau yog qhov zoo rau kev tsim cov duab nyuaj yam tsis muaj annealing.
Yog tias xav tau cov hlau stainless uas tawv dua lossis muaj zog dua rau kev siv kho mob, 304 tuaj yeem ua kom tawv los ntawm kev ua haujlwm txias. Thaum annealed, 304 thiab 304L steels yog cov ductile heev thiab tuaj yeem yooj yim tsim, khoov, rub tob lossis tsim. Txawm li cas los xij, 304 tawv sai thiab yuav xav tau ntxiv annealing kom txhim kho ductility rau kev ua tiav ntxiv.
304 stainless hlau yog siv dav hauv ntau yam kev lag luam thiab kev siv hauv tsev. Hauv kev lag luam khoom siv kho mob, 304 yog siv rau qhov chaw uas muaj kev tiv taus xeb siab, zoo nkauj, muaj zog, raug, ntseeg tau thiab huv si.
Rau cov hlau tsis xeb phais, feem ntau yog siv cov hlau tsis xeb qib tshwj xeeb, 316 thiab 316L. Nrog rau cov khoom sib xyaw ua ke ntawm chromium, nickel thiab molybdenum, cov hlau tsis xeb muab cov ntaub ntawv tshwj xeeb thiab txhim khu kev qha rau cov kws tshawb fawb thiab cov kws phais.
Ceeb Toom. Nws paub tias muaj qee zaum tsawg tsawg tus neeg lub cev tiv thaiv kab mob tsis zoo (ntawm daim tawv nqaij thiab thoob plaws lub cev) rau cov ntsiab lus nickel hauv qee cov hlau tsis xeb. Hauv qhov no, titanium tuaj yeem siv hloov stainless hlau. Txawm li cas los xij, Titanium muaj cov kev daws teeb meem kim dua. Feem ntau, stainless hlau yog siv rau kev cog hniav ib ntus, thaum titanium kim dua tuaj yeem siv rau kev cog hniav tas mus li.
Piv txwv li, lub rooj hauv qab no teev qee qhov kev siv tau rau cov khoom siv kho mob stainless hlau:
