Njira yopewera makutidwe ndi okosijeni a ma electrode a graphite panthawi yopanga zitsulo.Maelekitirodi a graphite amagwiritsidwa ntchito muzitsulo za arc monga zida zogwiritsira ntchito, ndipo ndalama zomwe amagwiritsira ntchito zimakhala pafupifupi 10-15% ya mtengo wopangira zitsulo zamagetsi.

M'zaka zaposachedwa, pofuna kupititsa patsogolo zokolola za ng'anjo zamagetsi ndi kuchepetsa kugwiritsira ntchito mphamvu, ng'anjo zamagetsi zakhala zikugwira ntchito zolemetsa kwambiri, ndipo kugwiritsira ntchito okosijeni kwa malo a electrode kumawonjezeka, motero kumawonjezera kugwiritsira ntchito electrode ndi kusungunula ndalama. inu oxidize graphite elekitirodi

Ma electrode a graphite amatha kutetezedwa ku okosijeni pogwiritsa ntchito zokutira zoteteza pamwamba pa elekitirodi.Nazi njira zina zopewera makutidwe ndi okosijeni a ma electrode a graphite:

1. Choyamba, bwalo la grooves osaya ndi machined pamwamba pa elekitirodi graphite, cholinga chake ndi kupanga cermet wosanjikiza akhoza mwamphamvu kutsatira pamwamba pa graphite elekitirodi, ndiyeno graphite elekitirodi ndi usavutike mtima pafupifupi 250 ℃ mu. ng'anjo yotentha, ndiyeno mfuti yachitsulo yopopera imagwiritsidwa ntchito pa electrode.Pamwamba, uzani wosanjikiza woonda wa aluminiyamu, uzani wosanjikiza wina wa cermet slurry pa aluminiyamu wosanjikiza, ndiyeno gwiritsani ntchito carbon arc kuti sinter slurry, spray slurry ndi arc sinter, bwerezani 2-3 kuti mupange cermet. makulidwe okwanira.

Resistivity ya cermet ndi 0.07-0.1pm, yomwe ili yotsika kuposa ya graphite electrode.Pa 900 ℃ kwa 50h, mpweya ndi wosasunthika ndipo kutentha kwa ℃ ndi 1750-1800 ℃.Zomwe zimapangidwira sizimakhudza zitsulo zosungunuka.Kuchulukitsa zopangira, magetsi ndi ntchito zomwe zimagwiritsidwa ntchito popaka odana ndi okosijeni zidzakulitsa mtengo wa maelekitirodi a graphite ndi 10%, koma kugwiritsa ntchito ma elekitirodi a graphite pa tani ya ng'anjo yamagetsi kumatha kuchepetsedwa ndi 20-30% (zotsatira zake zogwiritsidwa ntchito pang'anjo zamagetsi wamba).Popeza kuti zokutira ndizowonongeka, cermet ndi zinthu zowonongeka, choncho pewani kugundana mukamagwiritsa ntchito, ndipo musapangitse kuti chophimbacho chichoke.

2. Kuchepetsa kukhudzana ndi mpweya: Ma electrode a graphite ayenera kusungidwa pamalo owuma komanso opanda mpweya kuti asawonongeke ndi chinyezi ndi mpweya.Izi zidzathandiza kupewa okosijeni.

3. Kuchepetsa kutentha kwa ntchito: Kugwiritsira ntchito electrode pa kutentha kochepa kungachepetse mwayi wa okosijeni.Izi zitha kutheka pochepetsa komwe kulipo kapena kukulitsa malo a electrode.

4. Kugwiritsa ntchito mpweya woteteza: Gasi wotetezera monga argon kapena nayitrogeni angagwiritsidwe ntchito panthawi yogwira ntchito kuti ateteze okosijeni.Mpweya umathandizira kupanga mpweya woteteza kuzungulira electrode.

5. Kuyeretsa koyenera: Kuyeretsa koyenera kwa electrode musanayambe ntchito kumatha kuchotsa zonyansa zilizonse zomwe zingayambitse okosijeni.

Kuchuluka kwa ntchito: Oyenera mankhwala graphite monga maelekitirodi graphite, anode carbon midadada, electrolytic zotayidwa zomera, graphite zisamere pachakudya, graphite crucibles, ndi zinthu zina graphite pamwamba kusindikiza odana ndi makutidwe ndi okosijeni, kusindikiza odana ndi dzimbiri, kutalikitsa moyo wa mankhwala graphite ndi pa osachepera 30%, kuwonjezera mphamvu zakuthupi.
