Qes Oxygen Copper Qws VS Oxygen-free Copper Rod
Qes-oxygen tooj liab pas nrig: Cov pas nrig tooj liab tsim los ntawm kev nruam casting thiab dov txoj kev yog kub dov raws li kev tiv thaiv. Cov ntsiab lus oxygen yog nyob rau hauv thaj tsam ntawm 200-500ppm, tab sis qee zaum nws siab li 700ppm. Feem ntau, cov tooj liab uas ua los ntawm txoj kev no muaj qhov ci ntsa iab, uas yog hu ua low-oxygen tooj liab pas nrig, qee zaum kuj hu ua polished pas nrig.
Cov pas nrig tooj liab uas ua los ntawm cov pa oxygen-dawb tooj liab-casting txoj kev hu ua oxygen-dawb tooj liab pas nrig thaum cov ntsiab lus oxygen qis dua 10ppm.
Txog kev nqus pa thiab tshem tawm cov pa oxygen thiab nws lub xeev ntawm kev muaj sia nyob
Cov ntsiab lus oxygen ntawm cathode tooj liab rau kev tsim cov pas nrig tooj liab feem ntau yog 10-50ppm, thiab cov khoom solubility ntawm oxygen hauv tooj liab yog li 2ppm ntawm chav tsev kub. Cov pa oxygen ntawm cov pas nrig tooj liab qis feem ntau yog 200 (175) - 400 (450) ppm, yog li cov pa oxygen tau nqus rau hauv cov kua hauv lub xeev ntawm tooj liab. Los ntawm qhov kev xav ntawm microstructure, cov pa oxygen hauv qis-oxygen tooj liab muaj nyob ze ntawm thaj tsam ntawm cov qoob loo hauv daim ntawv ntawm tooj liab oxide, uas yog ib txwm muaj rau cov pas hlau tsis tshua muaj oxygen, tab sis tsis tshua muaj oxygen-dawb tooj liab rods. Cov tsos ntawm tooj liab oxide nyob rau hauv daim ntawv ntawm kev koom tes nyob rau hauv lub grain ciam teb muaj kev cuam tshuam tsis zoo rau lub toughness ntawm cov khoom. Txawm li cas los xij, cov pa oxygen hauv cov tooj liab tsis muaj oxygen tsawg heev, yog li qhov microstructure ntawm cov tooj liab no zoo ib yam thiab ib-theem, uas muaj txiaj ntsig zoo rau cov tawv nqaij.
Qhov sib txawv ntawm cov qauv kub-kuav los tiag thiab cov qauv cam khwb cia
Qes-oxygen tooj liab pas nrig yog kub dov, yog li nws cov qauv belongs rau cov qauv kub ua haujlwm. Tus qauv casting qub tau tawg lawm, thiab daim ntawv ntawm recrystallization tau tshwm sim thaum tus pas nrig yog 8 hli, thaum lub pas nrig tooj liab tsis muaj oxygen belongs rau cov qauv casting, nrog cov nplej ntxhib. Qhov yuav tsum tau ua kom muaj kev vam meej annealing ntawm oxygen-dawb tooj liab yog tias lub zog annealing ntawm thawj annealing ntawm cov xaim rub los ntawm tus pas nrig tsis muaj cov qauv casting yuav tsum yog 10-15 feem pua siab tshaj qhov qis-oxygen tooj liab nyob rau hauv tib qhov xwm txheej. . Tom qab kev kos duab tas mus li, cov npoo txaus yuav tsum tau tshwj tseg rau lub zog annealing nyob rau theem tom ntej thiab cov txheej txheem sib txawv yuav tsum tau ua kom muaj cov pa oxygen tsawg thiab tsis muaj oxygen tooj liab kom ntseeg tau tias cov khoom siv tau yooj yim hauv cov txheej txheem thiab cov xaim tiav.
Qhov sib txawv ntawm qhov hloov pauv ntawm cov pa oxygen thiab qhov ua tau kub dov tsis xws luag
Lub stretchability ntawm oxygen-dawb tooj liab pas nrig yog superior rau cov uas tsis muaj-oxygen tooj liab pas nrig nyob rau hauv tag nrho cov hlau diameters. Ntxiv nrog rau cov laj thawj saum toj no, cov pas nrig tooj liab tsis muaj oxygen muaj cov ntsiab lus tsawg dua, cov ntsiab lus oxygen ruaj khov thiab tsis muaj qhov tsis xws luag uas yuav tshwm sim thaum kub dov. Nyob rau hauv tus txheej txheem ntawm nruam casting thiab dov, yog tias cov txheej txheem tsis ruaj khov thiab kev saib xyuas cov pa oxygen tsis nruj, cov ntsiab lus ntawm cov pa oxygen tsis ruaj khov yuav cuam tshuam ncaj qha rau kev ua haujlwm ntawm tus pas nrig.
Toughness txawv ntawm qis-oxygen tooj liab pas nrig thiab oxygen-dawb tooj liab pas nrig
Ob leeg tuaj yeem rub tau mus rau {{0}}.015mm, tab sis qhov kev ncua deb ntawm cov xov hlau zoo ntawm cov qib qis qis oxygen-dawb tooj liab nyob rau hauv qhov kub thiab txias superconducting hlau tsuas yog 0.001mm.
Economic sib txawv ntawm raw cov ntaub ntawv thiab ntau lawm kab
The manufacturing of oxygen-free copper rods requires high-quality raw materials. Generally, when drawing copper wire with diameter>1mm, qhov zoo ntawm qis-oxygen tooj liab pas nrig yog pom tseeb, thaum qhov zoo ntawm cov pa oxygen dawb tooj liab pas nrig yog pom tseeb dua thaum kos tooj liab hlau nrog txoj kab uas hla.<0.5mm.
Qhov sib txawv ntawm txoj kev ua hlau
Cov txheej txheem ntawm cov hlau tsis muaj oxygen tooj liab tsis tuaj yeem raug xa mus rau cov txheej txheem tsim cov hlau tsis muaj pa oxygen, yam tsawg kawg ntawm cov txheej txheem annealing ntawm ob qhov sib txawv. Vim hais tias qhov yooj yim ntawm cov hlau yog cuam tshuam los ntawm cov khoom muaj pes tsawg leeg thiab cov pas nrig ua, hlau ua thiab cov txheej txheem annealing, nws tsis tuaj yeem hais tau yooj yim tias tsis tshua muaj oxygen tooj liab lossis tooj liab tsis muaj oxygen yog mos thiab tawv.
