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. Xav paub ntxiv.
Los ntawm lawv tus kheej xwm, cov khoom siv tsim los rau kev siv kho mob yuav tsum ua tau raws li cov qauv tsim thiab kev tsim khoom nruj heev. Hauv lub ntiaj teb ntawm kev foob thiab kev thov nyiaj rov qab rau kev raug mob lossis kev puas tsuaj los ntawm kev kho mob tsis raug cai, txhua yam uas kov lossis raug phais cog rau hauv tib neeg lub cev yuav tsum ua haujlwm raws nraim li tsim thiab yuav tsum tsis txhob ua tsis tiav.
Cov txheej txheem tsim thiab tsim cov khoom siv kho mob muaj qee qhov teeb meem nyuaj tshaj plaws rau kev tshawb fawb txog cov ntaub ntawv thiab kev tsim kho rau 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 txoj haujlwm sib txawv, yog li cov kws tshawb fawb thiab cov engineers siv ntau yam khoom siv los pab ua kom tau raws li cov qauv tsim qauv nruj tshaj plaws.
Cov hlau tsis xeb yog ib qho ntawm cov ntaub ntawv siv ntau tshaj plaws rau kev tsim cov khoom siv kho mob, tshwj xeeb tshaj yog cov hlau tsis xeb 304.
Cov hlau tsis xeb 304 tau lees paub thoob ntiaj teb tias yog ib qho ntawm cov khoom siv tsim nyog tshaj plaws rau kev tsim cov khoom siv kho mob rau ntau yam kev siv. Qhov tseeb, nws yog cov hlau tsis xeb uas siv ntau tshaj plaws hauv ntiaj teb niaj hnub no. Tsis muaj lwm qib ntawm cov hlau tsis xeb tuaj yeem ua ntau hom, ua tiav thiab ntau yam kev siv sib txawv. Cov Khoom Siv Hlau Tsis xeb 304 muab cov khoom siv tshwj xeeb ntawm tus nqi sib tw, yog li ua rau nws yog qhov kev xaiv zoo rau cov lus qhia ntawm cov khoom siv kho mob.
Kev tiv taus xeb siab thiab cov pa roj carbon tsawg yog cov yam tseem ceeb uas ua rau 304 stainless hlau haum rau kev siv kho mob dua li lwm cov qib ntawm stainless hlau. Qhov kev lees paub tias cov khoom siv kho mob yuav tsis cuam tshuam nrog cov ntaub so ntswg ntawm lub cev, cov khoom siv ntxuav siv rau kev tua kab mob, thiab qhov tawv, rov ua dua thiab tsim kua muag uas ntau cov khoom siv kho mob ntsib txhais tau tias stainless hlau 304 yog cov khoom siv zoo meej rau tsev kho mob, phais thiab kev siv kho mob thaum muaj xwm ceev, thiab ntau ntxiv.
Tsis yog tsuas yog cov hlau tsis xeb 304 muaj zog xwb, nws tseem siv tau zoo heev thiab tuaj yeem rub tob yam tsis tas yuav 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 siv khoob.
Kuj tseem muaj ntau hom hlau tsis xeb 304 uas muaj cov khoom siv zoo dua rau cov ntawv thov tshwj xeeb, xws li 304L, uas yog cov hlau uas tsis muaj carbon ntau, rau cov xwm txheej hnyav uas xav tau kev vuam uas muaj zog heev. Cov khoom siv kho mob yuav muaj 304L qhov twg xav tau kev vuam kom tiv taus ntau yam kev co, kev ntxhov siab ntev thiab/lossis kev ntxhov siab, thiab lwm yam. Hlau tsis xeb 304L kuj yog hlau kub qis, uas txhais tau tias nws tuaj yeem siv rau hauv cov ntawv thov uas xav kom cov khoom ua haujlwm hauv qhov kub txias heev. Rau cov chaw muaj kev xeb heev, 304L kuj tseem tiv taus kev xeb intergranular ntau dua li cov hlau tsis xeb zoo sib xws.
Qhov kev sib xyaw ua ke ntawm lub zog qis thiab lub peev xwm loj elongation txhais tau tias 304 stainless hlau yog qhov zoo tagnrho rau kev tsim cov duab nyuaj yam tsis tas yuav tsum tau annealing.
Yog tias cov ntawv thov kho mob xav tau cov hlau tsis xeb uas tawv dua lossis muaj zog dua, 304 tuaj yeem ua haujlwm kom tawv los ntawm kev ua haujlwm txias. Hauv qhov xwm txheej annealed, 304 thiab 304L yog cov ductile heev thiab tuaj yeem yooj yim tsim, khoov, kos tob lossis tsim. Txawm li cas los xij, 304 tawv sai thiab yuav xav tau ntxiv annealing kom nce ductility rau kev ua haujlwm 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 qhov twg qhov kev tiv thaiv corrosion siab, zoo formability, lub zog, kev tsim khoom raug, kev ntseeg siab thiab kev huv huv yog qhov tseem ceeb tshwj xeeb.
Rau cov hlau tsis xeb phais, cov qib tshwj xeeb ntawm cov hlau tsis xeb feem ntau yog siv - 316 thiab 316L. Los ntawm kev sib xyaw cov ntsiab lus chromium, nickel thiab molybdenum, cov hlau tsis xeb muab cov kws tshawb fawb thiab cov kws phais cov ntaub ntawv qee yam tshwj xeeb thiab txhim khu kev qha.
Ceev Faj - Muaj tej yam tsawg tsawg, lub cev tiv thaiv kab mob ntawm tib neeg paub tias yuav ua rau tsis zoo (tawv nqaij thiab tag nrho lub cev) rau cov nickel uas muaj nyob hauv qee cov hlau tsis xeb. Hauv qhov no, titanium siv tau los hloov cov hlau tsis xeb. Txawm li cas los xij, Titanium muaj ntau yam kev daws teeb meem kim dua. Feem ntau, stainless hlau siv rau kev cog hniav ib ntus, thaum titanium kim dua siv tau rau kev cog hniav tas mus li.
Piv txwv li, cov npe hauv qab no piav qhia txog qee cov ntawv thov kho mob rau cov hlau tsis xeb:
