Dab tsi yog Oxygen -Free Copper?
Oxygen- tooj liab dawb yog siab - purity tooj liab nyob rau hauv uas cov ntsiab lus oxygen tau khaws cia nyob rau theem qis heev thiab tsis muaj cov ntsiab lus deoxidising seem nyob hauv cov hlau. Hauv kev xyaum, cov lus piav qhia npog ib tsev neeg ntawm cov qhab nia es tsis yog ib qho khoom siv, thiab cov kev txwv tseeb nyob ntawm tus qauv siv. Cov lus qhia dav dav hauv Suav qib yuav tsum yog cov pa oxygen tsis ntau dua 0.003 feem pua, tag nrho cov impurities tsis ntau dua 0.05 feem pua thiab tooj liab purity ntau dua 99.95 feem pua. Cov pa oxygen nruj heev- qib electrolytic dawb, UNS C10100, mus ntxiv thiab txwv cov pa oxygen rau 0.0005 feem pua ntawm tooj liab ntawm 99.99 feem pua tsawg kawg.
Qhov sib txawv ntawm cov pa oxygen- tooj liab dawb thiab cov tooj liab ntshiab zoo tib yam yog nyob rau hauv yuav ua li cas cov yaj tau ua. Ordinary tawv pitch tooj liab yog cam khwb cia nrog ib tug tswj cov pa oxygen cov ntsiab lus uas ua ke nrog residual impurities kom lawv tsis muaj mob. Oxygen- qib dawb yog hloov pauv thiab muab pov rau hauv qhov chaw tiv thaiv lossis hauv lub tshuab nqus tsev, thiab txhua qhov deoxidation yog ua los ntawm txoj kev uas tsis muaj cov khoom seem tom qab.
Cov txiaj ntsig zoo yog cov hluav taws xob siab thiab thermal conductivity, zoo heev ductility thiab, qhov tseem ceeb tshaj plaws, kev tiv thaiv rau hydrogen embrittlement. Vim tias tsis muaj cuprous oxide nyob rau hauv cov qauv, kub txo cov cua tsis tuaj yeem tsim cov pa ntawm cov ciam teb, thiab cov khoom tsis tso dej vapor thaum nws siv hauv lub hnab ntawv nqus.
Qib thiab Standards
Ob peb qib poob rau hauv cov pa oxygen- pub dawb, thiab txhua tus tau txhais los ntawm nws tus kheej cov kev txwv thiab cov qauv khoom.
| Qib | Cim | Hom qauv |
|---|---|---|
| C10100 | Oxygen-dawb electrolytic tooj liab, tooj liab 99.99 feem pua tsawg kawg, oxygen 0.0005 feem pua siab tshaj | ASTM B170, ASTM F68, ASTM B152, ASTM B187 |
| C10200 | Oxygen-dawb tooj liab nrog qis conductivity yuav tsum tau tshaj C10100, oxygen txog 0.001 feem pua siab tshaj | ASTM B152, ASTM B187, ASTM B49 |
| TU1 thiab TU2 tsev neeg | Suav cov pa oxygen- cov qib tooj liab dawb nrog kev txwv cov pa oxygen ntxiv | GB / T 5231, nrog cov qauv khoom siv rau sawb, raj thiab pas nrig |
| Cov qib European | Qib tau teev tseg los ntawm cov ntsiab lus oxygen thiab cov chav kawm conductivity | TS EN 13601 Cov pas nrig, bar thiab xaim, EN 13602 rau kos hlau |
Vim hais tias lub npe oxygen- tooj liab dawb yog siv xoob hauv kev lag luam, kev yuav khoom yuav tsum nco ntsoov hais tus lej UNS lossis qib hauv tebchaws ua ke nrog cov qauv khoom siv. Daim ntawv pov thawj uas tsuas yog hais txog cov pa oxygen-dawb yam tsis tau sau cov qhab nia tsis tuaj yeem kuaj xyuas qhov tshwj xeeb.
Kev sib xyaw thiab cov khoom yuav tsum muaj
Lub hnab ntawv khoom ntawm oxygen- tooj liab dawb yog txhais los ntawm peb tus lej: cov ntsiab lus oxygen, tag nrho cov ntsiab lus impurity thiab conductivity.
| Parameter | Yam yuav tsum tau muaj |
|---|---|
| Cov ntsiab lus oxygen | Tsis ntau dua 0.003 feem pua rau cov pa oxygen- chav kawm dawb, thiab 0.0005 feem pua siab tshaj plaws rau C10100 |
| Tag nrho impurities | Tsis ntau tshaj 0.05 feem pua rau cov chav kawm dav dav |
| Tooj purity | Ntau dua 99.95 feem pua, thiab 99.99 feem pua tsawg kawg rau C10100 |
| Hluav taws xob conductivity | Siab heev, tshaj 100 feem pua IACS nyob rau hauv cov mob annealed rau qib siab purity siab tshaj |
| Deoxidant residues | Tsis muaj leej twg tso cai rau hauv cov pa oxygen - qib dawb |
Mechanical zog yog temper dependent, yog li tensile zog, yield zog thiab elongation los ntawm cov khoom txheem thiab temper es tsis yog los ntawm qib npe. Annealed khoom muaj qhov siab tshaj plaws ductility thiab conductivity; nyuaj tempers lag luam ductility rau lub zog nyob rau hauv lub tsheb npav bar, tiv tauj thiab structural conductor daim ntaub ntawv.
Vim li cas Oxygen Cov ntsiab lus tseem ceeb
Yog vim li cas kev lag luam mus rau qhov teeb meem ntawm kev tshem tawm ob peb qhov kawg ntawm ib lab ntawm cov pa oxygen los ntawm peb qhov tsis ua haujlwm thiab kev ua haujlwm zoo.
Hydrogen embrittlement yog thawj. Hauv cov pa oxygen- bearing tooj liab, hydrogen ntawm qhov kub siab yuav txo tau cov kab mob sib kis oxide thiab ua rau cov hnab tshos ntawm cov ciam teb, uas ua rau cov hlau nkig thiab tuaj yeem ua rau tawg thaum tsim, vuam lossis siab - kev pabcuam kub. Oxygen- tooj liab dawb tsis muaj dab tsi rau hydrogen los teb nrog, yog li lub tshuab tsis tuaj yeem pib.
Outgassing hauv lub tshuab nqus tsev yog qhov thib ob. Hauv lub tshuab nqus tsev lossis lub tshuab kaw, ib qho oxide tam sim no tuaj yeem tso dej vapor thiab lwm yam volatiles uas degrade lub nqus tsev vacuum thiab tshuaj lom rhiab qhov chaw. Cov hlau uas tseem ceeb tsis muaj oxides nyob twj ywm huv.
Conductivity thiab formability yog qhov thib peb. Oxide hais thiab residual deoxidants ob qho tib si tawg electrons thiab cuam tshuam cov hlau lattice, yog li tshem tawm lawv tsa hluav taws xob thiab thermal conductivity thiab txhim kho ductility rau kev ua haujlwm zoo xws li npib thiab nplua blanking.
Tempers, Forms thiab Fabrication
Oxygen-dawb tooj liab yog muab los ua phaj, ntawv, sawb, dov bar, tsheb npav, pas nrig, hlau, raj thiab forging Tshuag, nyob rau hauv annealed thiab txias ua hauj lwm tempers. Cov khoom siv Annealed yog siv qhov siab tshaj plaws ductility thiab conductivity yuav tsum tau, hard drawn tempers qhov tawv thiab lub zog teeb meem.
Fabrication yog ncaj nraim tab sis cov kev ua haujlwm tseem ceeb. Vuam los ntawm cov pa roj tungsten arc, electron beam thiab kev tiv thaiv txoj kev yog ib txwm muaj, thiab brazing nyob rau hauv ib qho chaw tiv thaiv yog dav siv rau cov rooj sib txoos, nrog rau cov nyiaj -raws li muab tub lim hlau xaiv qhov twg conductivity yuav tsum tau khaws cia. Qhov sib koom ua ke yuav tsum tau tiv thaiv los ntawm oxidation thaum lub sij hawm cua sov, vim hais tias re- oxidising saum npoo swb lub hom phiaj ntawm kev qhia qib. Machining yuav tsum tau siv cov cuab yeej ntse vim tias cov khoom yog mos thiab gummy, thiab kev ntxhov siab tom qab ua haujlwm hnyav yuav tsum tau nqa tawm hauv qab ntawm qhov recrystallisation ntau yam kom tsis txhob npau taws.
Kev huv huv yog ib feem ntawm qhov tshwj xeeb, tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob- cov ntaub ntawv. Tuav nrog cov hnab looj tes huv si, zam tsis txhob muaj cov kab mob ferrous thiab khaws cia kom deb ntawm cov av noo lossis sulfide-cov huab cua puag txhua qhov yuav pab khaws cov conductivity thiab qhov zoo ntawm qhov chaw.
