Kodi ma electrode a graphite amagwira ntchito bwanji?

Tiye tikambirane Kodi ma electrode a graphite amagwira ntchito bwanji?Njira yopanga ma elekitirodi a graphite ndi Chifukwa chiyani ma elekitirodi a graphite amafunikira m'malo?
1. Kodi ma elekitirodi a graphite amagwira ntchito bwanji?
Ma electrodes ndi gawo la chivindikiro cha ng'anjo ndipo amasonkhanitsidwa kukhala mizati.Magetsi amadutsa mu maelekitirodi, kupanga arc ya kutentha kwakukulu komwe kumasungunula chitsulocho.
Ma electrode amasunthidwa pansi pazinyalala panthawi yosungunuka.Ndiye arc amapangidwa pakati pa elekitirodi ndi zitsulo.Poganizira zachitetezo, magetsi otsika amasankhidwa pa izi.Pambuyo potetezedwa ndi ma electrode, magetsi amawonjezeka kuti afulumizitse kusungunuka.
2. graphite electrode kupanga ndondomeko
Ma electrode a graphite amapangidwa makamaka ndi petroleum coke ndi singano coke, ndipo phula la malasha limagwiritsidwa ntchito ngati chomangira.Zimapangidwa ndi calcination, kusakaniza, kukanda, kukanikiza, kuwotcha, graphitization ndi Machining.Ndiko kutulutsa mphamvu yamagetsi mu mawonekedwe a arc yamagetsi mu ng'anjo yamagetsi yamagetsi.Kondakitala yemwe amatenthetsa ndi kusungunula mtengowo akhoza kugawidwa mu electrode yamphamvu ya graphite, electrode yamphamvu ya graphite ndi electrode yapamwamba kwambiri ya graphite molingana ndi ndondomeko yake ya khalidwe.

3. N’chifukwa chiyani ma elekitirodi a graphite amafunika kusinthidwa?
Malinga ndi mfundo yogwiritsira ntchito, pali zifukwa zingapo zosinthira ma electrode a graphite.
• Kumapeto kwa ntchito: Izi zikuphatikizapo kutsika kwa zinthu za graphite chifukwa cha kutentha kwa arc ndi kutaya kwa mankhwala pakati pa electrode ndi chitsulo chosungunuka ndi slag.Kutentha kwakukulu kwa kutentha kwapamwamba kumapeto kumatengera kachulukidwe kameneka kameneka kakudutsa mu electrode;komanso zokhudzana ndi awiri a elekitirodi mbali pambuyo makutidwe ndi okosijeni;Kutha kudya kumakhudzananso ndi kuyika electrode m'madzi achitsulo kuti muwonjezere mpweya.
• Lateral oxidation: The mankhwala zikuchokera ma elekitirodi ndi carbon, Mpweya adzakhala oxidize ndi mpweya, nthunzi madzi ndi mpweya woipa pansi zinthu zina, ndi makutidwe ndi okosijeni kuchuluka kwa ma elekitirodi mbali zikugwirizana ndi unit makutidwe ndi okosijeni mlingo ndi kukhudzana area.Normal, Electrode mbali makutidwe ndi okosijeni amawerengera pafupifupi 50% ya ma elekitirodi onse.M'zaka zaposachedwa, kuti apititse patsogolo kuthamanga kwa ng'anjo yamagetsi, kuwonjezereka kwa mpweya wa okosijeni kumawonjezeka, kutaya kwa okosijeni kwa electrode kumawonjezeka.
• Kutayika kotsalira: Pamene electrode ikugwiritsidwa ntchito mosalekeza pamgwirizano wa ma electrode apamwamba ndi apansi, kachigawo kakang'ono ka electrode kapena cholumikizira chimachotsedwa chifukwa cha kupatulira kwa okosijeni kwa thupi kapena kulowa kwa ming'alu.
• Kupukuta ndi kugwetsa pamwamba: Zotsatira za kusagwira bwino kwa kutentha kwa electrode pa nthawi yosungunuka. Phatikizani thupi la electrode losweka ndi kusweka kwa nsonga.Electrode yosweka ikugwirizana ndi khalidwe ndi makina a graphite elekitirodi ndi nipple, komanso zokhudzana ndi ntchito yopanga zitsulo.
