Dab tsi yog oxygen - tooj dawb tooj? Nws txawv li cas ntawm tooj liab dog dig?
Oxygen - tooj dawb tooj liab tau suav hais tias yog cov oxygen dawb thiab cov deoxidizers lossis cov seem. Txawm li cas los xij, nws yeej tseem muaj cov nqi tsawg heev ntawm cov pa thiab qee qhov tsis txaus ntseeg {2} Cov nyiaj twv! Raws li cov qauv, nws cov ntsiab lus oxygen yuav tsum tsis txhob tshaj 0.003%, nws cov ntsiab lus tsis huv yuav tsum tsis pub tshaj 0.05%, thiab nws cov tooj liab kev coj ua yuav tsum muaj ntau dua 99.95%.
Raws li ib tug tshwm sim, oxygen - dawb tooj liab, muaj ntau dua cov khoom siv hluav taws xob tsis muaj zog, nrog rau kev ua kom zoo dua thiab cov txheej txheem sib xyaw. Oxygen {{2} Tus tooj dawb dawb yog feem ntau siv nyob rau hauv cov chaw siv hluav taws xob, xws li cov ntsaws ruaj ruaj, lub tshuab nqus tsev, lub tshuab nqus tsev, thiab cov tshuab txuas. Oxygen {{4} h} dawb tooj dawb muaj cov txheej txheem zoo heev thiab tsim nyog rau cov machining zoo. Oxygen - tooj dawb tuaj yeem txiav txim siab tshwj xeeb hom tooj liab. Cov qib tseem ceeb ntawm oxygen {{8} Tsis muaj tus tooj dawb dawb, Tu1, T10100, thiab C10200.
TU1: Purity nce 99.97%, cov ntsiab lus oxygen tsis muaj ntau dua 0.003%, thiab tag nrho cov ncauj lus tsis sib xws tsis muaj ntau dua 0.03%. Qhov no oxygen {{5} dawb tooj liab khav purity, zoo heev conductivity, thiab yog cov txheej txheem ntawm hydrogen embrittlement. Nws yog qhov siab {{{{{}} zoo tooj liab cov khoom siv feem ntau siv nyob rau hauv cov ntawv thov siab thiab kev ua tau zoo, xws li hluav taws xob thiab hluav taws xob ua tshuab hluav taws xob.
TU2: Cov ntsiab lus tooj liab ntau dua 99.95%, cov ntsiab lus oxygen tsis muaj ntau dua 0.003%, thiab tag nrho cov ncauj lus tsis loj dua 0.05%. TU2 oxygen - tooj dawb Nws yog feem ntau siv nyob rau hauv kev tsim khoom thiab kev ua cov khoom siv ib puag ncig thiab kev sib txuas lus, xws li cov khoom tuav, yoj tes, thiab cov khoom siv hluav taws xob, thiab khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob.
C10100: Feem ntau muaj ntau tshaj 99.99% tooj liab thiab muaj cov ntsiab lus oxygen tsawg dua 0.001%. Qhov no yog qhov siab -}} Cov khoom siv tooj hluav taws xob zoo nkauj, corrosion tsis zoo, thiab zoo nkauj heev. Nws yog dav siv nyob rau hauv kev lag luam xws li hluav taws xob hluav taws xob xws li cov khoom siv hluav taws xob, aerospace, tsheb tsim khoom, thiab kis tshuab.
C10200: Tooj liab cov ntsiab lus ntau dua los yog sib npaug rau 99.95%, tag nrho cov impurities tsawg dua los yog sib npaug rau 0.05%. Nws tuaj yeem siv rau hauv cov tshuab nqus tsev, cov twj, thiab meters.
Tooj liab dog dig, tseem hu ua tooj liab, tau txais nws lub npe los ntawm nws cov paj yeeb - xim liab. Thaum nws yog feem ntau xa mus rau cov tooj liab ntshiab, qhov no tsis muaj tseeb. Hlaws nruj ua ntej theoretically yuav tsum muaj ze rau 100% tooj liab. Thaum nws yog tus tooj liab ntse, nws tsis yog qhov sib npaug rau tus tooj liab ntshiab.
Tooj liab muaj cov pa oxygen, tseem hu ua cov oxygen -}}} muaj tooj liab. Cov ntsiab lus tooj liab ntawm liab tooj liab liab los ntawm 99.5% rau 99.99%. Tooj liab muaj qhov hluav taws xob zoo thiab thermal conductivity, zoo heev cov yas, thiab yooj yim rau cov txheej txheem los ntawm kev nias kub thiab txias nias. Nws yog dav siv nyob rau hauv kev tsim cov khoom uas xav tau kev ua haujlwm zoo, xws li cov xov hlau zoo, cable electro - spark Tooj liab.
Cov qhab nia tseem ceeb ntawm liab tooj liab yog: T1, T2, thiab T3.
T1: Cov ntsiab lus tooj liab yog tsawg kawg 99.95%, nrog tag nrho cov impurities tsis tshaj 0.05%.
T2: Cov ntsiab lus tooj liab yog tsawg kawg 99.90%, nrog tag nrho cov impurities tsis tshaj 0.1%.
T3: Cov ntsiab lus tooj liab yog tsawg kawg 99.7%, nrog tag nrho cov impurities tsis tshaj 0.3%.
Ntxiv rau, cov qauv thoob ntiaj teb suav nrog cov qib xws li C11000. C11000 tseem muaj cov ntsiab lus tooj liab dua, feem ntau xav tau tooj liab + nyiaj cov ntsiab lus ntawm ntau dua lossis sib npaug rau 99.90%.
Qhov sib txawv ntawm cov tsos ntawm oxygen - dawb tooj liab thiab tooj liab liab yog raws li hauv qab no:
Xim
Tooj liab feem ntau zoo nkaus li liab doog - liab, uas yog qhov twg nws lub npe los ntawm. Cov xim yog kaj lug thiab muaj ib qho kev pom zoo. Vim nws yooj yim oxidation nyob rau hauv huab cua, tsaus tsaus nti lossis tsaus xim liab oxide zaj duab xis yog maj mam xim paj yeeb {}} xim liab tseem tuaj yeem pom.
Oxygen - dawb tooj liab feem ntau muaj cov liab tooj liab xim, kom zoo li silvery dawb lossis daj ntseg daj. Vim nws cov ntsiab lus tsawg kawg nkaus uas tsis tshua muaj pa, oxygen {{2} Cov xim dawb huv ntau dua li cov tooj liab, ua rau muaj qhov ntev dua, muaj qhov muag me ntsis, ci me me me.
Nto tas:
Tooj liab: Vim nws cov khoom mos kuj muaj kev phom sij, nws yog qhov txaus ntshai thiab muaj kev puas tsuaj thaum ua thiab siv, uas yuav cuam tshuam nws cov npoo ua tiav. Oxidized tooj liab yuav tshwm sim ntxhib thiab poob qee yam ntawm nws cov xim hlau luster.
Oxygen - dawb tooj liab: nws feem ntau muaj cov smoother, ntau qhov muag heev saum npoo. Vim tias oxygen {{2} dawb tooj dawb yog qhov zoo nkauj heev thiab muaj yooj yim dua kom ua tiav qhov zoo zoo thaum ua.
NCO TSEG: Muaj qhov sib txawv oxygen - dawb tooj liab tuaj yeem cuam tshuam los ntawm ntau yam kev ua si, suav nrog kev ua si, suav nrog kev kho deg, thiab qib oxidation. Hauv kev siv cov kev siv, lwm txoj kev, xws li kev soj ntsuam tshuaj lom neeg thiab cov khoom ntiag tug ntawm lub cev, tuaj yeem siv los sib txawv ntawm ob.
Qhov sib txawv hauv lub zog thiab hardnessing:
Tooj liab: Tus nqi qis hauv lub zog, softer nyob rau hauv hardness, thiab softer hauv kev ntxhib los mos. Qhov no ua rau nws raug rau kev deformation thaum lub sijhawm ua thiab siv. Piv txwv li, thaum manufacturing nyias- lub zog} Lub zog thiab tawv tawv ntawm tooj liab yuav tsum tau txiav txim siab los ntawm kev siv.
Oxygen - tooj dawb tooj dawb: Tom qab kev kho mob dawb, nws muaj lub zog siab thiab ua kom muaj zog dua li liab tooj liab. Qhov no ua rau oxygen - tooj dawb tooj kom tau zoo nyob rau hauv cov ntawv thov tiv thaiv kom tsis txhob muaj tseeb thiab hnav. Piv txwv li, hauv kev lag luam AERPACE, lub zog siab thiab hardness ntawm oxygen {}} dawb tooj tau raws li cov hlua khi kom haum ntawm cov dav hlau.
Nyob rau hauv cov nqe lus ntawm corrosion tsis kam, oxygen - tooj dawb tooj yog tiv taus liab dua liab.
Qhov sib txawv ntawm kev tawm tsam ntawm ob:
Tooj liab: Ntawm 20 degree, kev tiv thaiv yog kwv yees li 0.01851 ω · mm² / m (lossis 1.85 × 1051 · · m).
Liab tooj liab muaj hluav taws xob zoo tshaj plaws, thib ob nkaus rau nyiaj ntawm txhua cov hlau, ua rau nws cov khoom siv tseem ceeb. Txawm li cas los xij, nws qhov kev coj ua yog qis dua qis dua li ntawm oxygen {{1} h} tooj dawb tooj. Piv txwv li, hauv cov hluav taws xob hauv hluav taws xob, cov xov hlau tooj liab tau hloov kho tam sim no, tab sis lawv yuav tsis tau raws li qhov yuav tsum tau ua haujlwm hauv qhov twg hauv qhov uas yuav tsum muaj kev pheej hmoo siab. Oxygen {{4} Free} dawb tooj liab: qhov tiv taus ntawm 20℃yog kwv yees li 0.0171 × 10⁻⁶ω⁻⁶ω⁻⁶ω⁻⁶ω )1).
Oxygen - dawb tooj dawb muaj qhov ua tau zoo dua, feem ntau tshaj 100% analealed tooj liab tooj liab), siab dua li ntau dua tooj liab. Qhov no muab oxygen - dawb tooj liab tshwj xeeb hauv cov khoom siv thiab cov ntaub ntawv hluav taws xob. Piv txwv li, hauv high {{5 5}} Cov pa tsis ncaj ncees} dawb tooj} Tsis muaj o; kev siv teeb liab kev sib kis thiab txo cov paib teeb liab.
Lub tuam txhab muaj pawg ntawm cov coj tooj liab ua ntau lawm cov kab hauv Suav teb, suav nrog:
German tau yog precision tooj liab raj ntau lawm kab (ib xyoos tawm ntawm 30,000 tons)
Japanese technology Tooj liab ntawv tuav kab (thinnest txog li 6μm)
Tsis Siv Neeg Siab Tooj Liab Bar Nruam Extrusion Kab
Cov Ntawv Ntse Copper thiab Sawb Fining Mill Chav Tsev
Digitalized kev tswj hwm thiab kev tswj hwm ntawm tag nrho cov txheej txheem ntau lawm tau pom los ntawm cov khoom siv ntawm cov khoom lag luam, thiab qhov tseeb ntawm cov khoom tuaj yeem ncav cuag ± 0.01 hli.
