Ntchito ndi katundu wa graphite electrode:

1. Ntchito mu ng'anjo magetsi arc steelmaking

Maelekitirodi a graphite amagwiritsidwa ntchito kwambiri popanga zitsulo zamagetsi.Electric ng'anjo steelmaking ndi kugwiritsa ntchito maelekitirodi graphite kuyambitsa panopa mu ng'anjo.Mphamvu yamagetsi imadutsa mu gasi kumapeto kwa ma electrode kuti apange kutulutsa kwa arc, ndipo kutentha kopangidwa ndi arc kumagwiritsidwa ntchito posungunula.Malinga ndi mphamvu ya ng'anjo yamagetsi, ma electrode a graphite okhala ndi ma diameter osiyanasiyana amagwiritsidwa ntchito.Kuti ma electrode agwiritse ntchito mosalekeza, ma elekitirodi amalumikizidwa ndi ma electrode threaded joints.Maelekitirodi a graphite opangira zitsulo amakhala pafupifupi 70-80% ya kuchuluka kwa maelekitirodi a graphite.

2. Amagwiritsidwa ntchito mu ng'anjo yamagetsi yotentha yomira

Graphite elekitirodi kumizidwa ng'anjo magetsi matenthedwe zimagwiritsa ntchito kupanga ferroalloy, pakachitsulo koyera, chikasu phosphorous, matte ndi kashiamu carbide, etc. Iwo amakhala kuti m'munsi mwa elekitirodi conductive m'manda mu mlandu, kotero kuwonjezera pa kutentha. zopangidwa ndi arc pakati pa mbale yamagetsi ndi chiwongolero, Kutentha kwamakono kumapangidwanso ndi kukana kwa chiwongoladzanja pamene chikudutsa pamalipiro.Toni iliyonse ya silicon iyenera kudya pafupifupi 150kg ya maelekitirodi a graphite, ndipo toni iliyonse ya phosphorous yachikasu imayenera kudya pafupifupi 40kg ya maelekitirodi a graphite.

3. Amagwiritsidwa ntchito mu ng'anjo yotsutsa

Zida zopangira graphite zopangira zinthu za graphite, ng'anjo zosungunula zamagalasi osungunuka, ndi ng'anjo zamagetsi zopangira silicon carbide zonse ndi ng'anjo zotsutsa.Zida zomwe zili mu ng'anjoyo ndizomwe zimatenthetsa ndi zinthu zomwe ziyenera kutenthedwa.Kawirikawiri, ma elekitirodi a graphite oyendetsa amalowetsedwa mu khoma lamoto kumapeto kwa moto, kuti ma elekitirodi a conduction asawonongeke nthawi zonse.

4. Kwa processing

Zolemba zambiri za graphite electrode zimagwiritsidwanso ntchito pokonza zinthu zosiyanasiyana zowoneka ngati ma crucibles, mabwato a graphite, nkhungu zopondereza zotentha ndi zinthu zotenthetsera za ng'anjo zamagetsi za vacuum.Tikumbukenso kuti pali mitundu itatu ya zipangizo kupanga zipangizo graphite pa kutentha kwambiri, kuphatikizapo maelekitirodi graphite, nkhungu graphite ndi graphite crucibles.Graphite mu zinthu zitatuzi sachedwa ndi okosijeni kuyaka zimachitikira pa kutentha kwambiri, chifukwa mu mpweya wosanjikiza pamwamba pa zinthu.Kuwonjezeka kwa porosity ndi mawonekedwe otayirira kumakhudza moyo wautumiki.

Ma electrode a graphite amapangidwa makamaka ndi petroleum coke ndi singano coke, ndipo malasha phula phula ntchito ngati binder.Amapangidwa ndi calcination, batching, kukanda, kukanikiza, kuwotcha, graphitization, ndi Machining.Amatulutsa mphamvu yamagetsi mu mawonekedwe a arcs mu ng'anjo yamagetsi yamagetsi.Ma kondakitala otenthetsera ndi kusungunula mtengowo amatha kugawidwa kukhala ma elekitirodi amphamvu a graphite, maelekitirodi amphamvu a graphite ndi ma elekitirodi apamwamba kwambiri a graphite malinga ndi zizindikiro zawo.
