Oxygen-free copper and low-oxygen copper are definitely not the same material. Lawv muaj cov khoom sib txawv heev, thiab yog tias koj ua tib zoo paub qhov txawv lawv raws li qhov pom, koj tuaj yeem pom qee qhov sib txawv.
Ua ntej, cov txheej txheem ntau lawm ntawm oxygen {{0} {{-} toper tooj liab muaj sib txawv, raws li koj tuaj yeem qhia tau los ntawm lub npe. Lub ntsiab sib txawv ntawm ob yog cov ntsiab lus oxygen ... nyob rau lub sijhawm no, ib tus neeg hais tias, "Kuv paub ib tus muaj oxygen thiab lwm yam oxygen thiab lwm cov pa." Thaum lub suab nrov no yog lawm, nws tsis ncaj ncees lawm!
Txawm hais tias nws tau hu ua oxygen - tooj dawb tooj dawb, cov khoom siv no muaj cov pa oxygen! (Cov ntsiab lus tsuas yog me me xwb, tsis zoo, tab sis nws tsis yog oxygen {}} dawb tooj} dawb.) Muaj ntau qhov sib txawv, yog li tseem muaj qee yam sib txawv hauv lawv qhov kev ua tau zoo. Hais txog cov tsos, oxygen - tooj dawb tooj dawb muaj lub ntsej muag ci ntsa iab! Yog li, thaum koj ntsib ob yam khoom, cov pa oxygen {{} dawb tooj liab cov khoom siv muaj lub zog zoo nkauj.
Rov qab mus rau tus pas liab. Raws li tau hais ua ntej lawm, vim muaj cov txheej txheem ntau lawm, cov ntsiab lus oxygen thiab cov tsos ntawm tus pas liab kuj sib txawv. Tooj liab tus tsiaj tsim kev tsim cov khoom siv rau sab saum toj- kev kos duab hauv qab no 10 ppm thiab yog hu ua oxygen {}} tooj dawb tooj liab pas nrig.
Tooj liab tus tsiaj tsim kev siv cov txheej txheem txuas ntxiv thiab siv cov pa roj oxygen, tab sis qee zaum tuaj yeem ncav cuag cov qib siab li 700 ppm lossis saum toj no. Feem ntau, cov qauv no ua rau tooj liab nrog lub ci ci, qis}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Ntawm chav kawm, muaj tseem cov txheej txheem dip-txheej, uas muaj cov tseem ceeb dua.
Oxygen - dawb tooj liab pas nrig yog tsim los siv cov khoom siv txawv teb chaws lossis cov khoom tsim tawm, tab sis qhov sib txawv hauv cov khoom kawg tsis tseem ceeb. Nrog zoo tooj liab phaj xaiv thiab kev tswj ruaj khov tsim, cov khoom tsim hauv tsev tuaj yeem tsim cov pas nrig tooj liab nrog lub zog 0.05 tensile.
Oxygen - Dawb thiab qis -}}}}}}}} ecygen tooj liab tus pas nrig yooj yim los ntawm lawv cov ntsiab lus oxygen. Oxygen - dawb tooj dawb muaj cov ntsiab lus oxygen hauv qab no 10}}}}}}}}}}}}}}}}}}}}}}}} Tsawg - ease rod muaj cov ntsiab lus oxygen Oxygen - Tus pas nrig dawb yog feem ntau tsim kev siv cov qauv sab saum toj-} pead yog txuas ntxiv thiab dov thiab dov. Piv rau ob yam khoom, qis-}}}}}}} e oxygen comperties, xws li hloov cov khoom siv hlau, xws li cov khoom siv hlau yooj yim, lub caij nplooj ntoos hlav, thiab cov khoom cua sov. Txawm li cas los xij, tsawg {{20 {}} cov pa oxygen yog xav tau ntau dua nyob rau hauv cov nqe lus ntawm cov hlau kos duab! Rau tib tib 0.2mm nyias xaim, yog tias cov duab kos tsis zoo, cov kab uas tsis zoo, thaum lub sij hawm zoo-oxygen pas nrig yuav tawg.
Txawm li cas los xij, yog tias cov duab kos yog qhov zoo, tib lub pas nrig tuaj yeem tsim tau rau 0.05 hli, thaum zoo li tus pas nrig qis tsuas yog kos rau 0.1mm ntawm feem ntau. Tau kawg, cov xov hlau thannest, xws li 0.02mm, yuav tsum cia siab rau cov pa ntshuam {{5 5} dawb tooj liab pas nrig. Qee cov tuam txhab tau sim nrog stripping tsawg {{}} pa pack cig los kos 0.03mm nyias hlau, tab sis kuv tsis paub meej txog qhov no. Oxygen - tooj dawb tooj dawb feem ntau nyiam rau tus neeg hais lus cables. Qhov no yog vim oxic- tooj dawb tooj yog ua los ntawm ib {13} {}} tooj liab tooj liab yog ua los ntawm polycrystalline tooj liab.
Ob qho tib si qis -} cov pa tooj liab thiab oxi {1} xem siv cov xaim dawb, thiab tooj liab busbars. Lawv cov ntawv thov yog qhov zoo tib yam. Qhov sib txawv nyob hauv lawv cov ntsiab lus oxygen. Tus qauv hauv tebchaws qhia cov ntsiab lus pa oxygen ntawm tsawg dua 450 ppm rau tsawg dua 450 ppmen tooj liab, thaum tsawg dua 20- oxygen tooj liab.
Oxygen - dawb tooj liab muaj ntau dua resistivity thiab kev ua kom zoo hluav taws xob cov khoom siv feem ntau siv oxic {3} dawb tooj. Piv txwv li, thaum ua Enameled xaim xaim, oxic - tooj dawb tooj liab undouptedly ua rau qis qis. Thaum siv nyob rau hauv cov motors, kub tiam yog undoubtedly zoo dua li ntawm tsawg {} oxygen tooj liab. Yog li ntawd, zoo -} nco ntsoov cov neeg tsim khoom nyiam oxic- tooj dawb dawb li cov khoom siv dawb.
Tsis tas li ntawd, qis {{- pa tooj liab ua rau nws nyuaj los kos cov hlau thib dawb muaj ntau txoj kev ua tau zoo dua.
Yog li, txoj kev sib tam tam sim no yog: Tsawg - Cov pa tooj liab tau siv rau cov khoom siv hluav taws xob qis rau cov khoom lag luam qis nrog cov khoom tiv thaiv dawb. Txhua tus paub tias oxygen {{5 5} dawb tooj liab pas loj dua, tab sis puas yog tus nqi siab dua?
Tam sim no, qhov sab saum toj - Kos duab txoj kev yog thawj txoj kev siv los tsim cov oxygen {} dawb tooj liab pas nrig hauv Suav. Cov txheej txheem tseem ceeb no muaj cov qauv zoo xws li cov txheej txheem luv luv, muaj txiaj ntsig siab, tus nqi qis, thiab kev nqis peev tsawg. Yog li ntawd, tus nqi ntawm cov pa {{4 4}} dawb tooj liab pas nrig tsis yog siab dua li ntawm cov tooj liab liab. Tsis tas li ntawd, cov txheej txheem ntau lawm ntawm cov pa - tooj dawb dawb tau dhau los txhim kho 20 xyoo dhau los. Lub - dawb tooj liab Qws Cov Chaw Tsim Tshuaj tau yooj yim coj tus nqi oxygen yooj yim rau ib qib zoo sib xws li hais tias ntawm dog dig tooj liab pas nrig.
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.
