Hanya don hana iskar oxygen da na'urorin lantarki na graphite yayin aikin karfe.Ana amfani da na'urorin lantarki na graphite a cikin ƙarfe na ƙarfe a matsayin kayan da ake iya amfani da su, kuma farashin amfanin su ya kai kusan kashi 10-15% na farashin ƙarfe na tanderun lantarki.

A cikin 'yan shekarun nan, don inganta aikin tanda na lantarki da rage yawan amfani da wutar lantarki, wutar lantarki ta karbi ayyuka masu yawa, kuma yawan amfani da iskar oxygen da ake amfani da shi na kayan lantarki yana kara karuwa, ta haka ya kara yawan amfani da wutar lantarki da kuma narke farashin. To yaya za a yi. ka oxidize da graphite lantarki

Za'a iya kiyaye na'urorin lantarki na graphite daga iskar oxygen ta amfani da murfin kariya a saman lantarki.Anan akwai wasu hanyoyin don hana oxidation na lantarki na graphite:

1. Na farko, da'irar m tsagi ne machined a saman graphite lantarki, da manufar shi ne don sa cermet Layer iya da tabbaci manne da surface na graphite lantarki, sa'an nan kuma graphite lantarki ne mai tsanani zuwa game da 250 ℃ a. tanderun dumama, sannan a yi amfani da bindigar feshin karfe akan lantarki.A saman, fesa wani bakin ciki Layer na aluminum, fesa wani Layer na cermet slurry a kan aluminum Layer, sa'an nan kuma amfani da carbon arc zuwa sinter da slurry, fesa slurry da baka sinter, maimaita sau 2-3 don yin cermet Layer yana da isasshen kauri.

Resistivity na cermet shine 0.07-0.1pm, wanda yayi ƙasa da na graphite electrode.A 900 ℃ for 50h, da gas ne impermeable da shafi bazuwar zafin jiki ne 1750-1800 ℃.Rubutun kashi abun da ke ciki ba shi da wani tasiri a kan narkakkar karfe.Haɓaka albarkatun ƙasa, wutar lantarki da aiki da ake amfani da su a cikin murfin anti-oxidation zai haɓaka farashin lantarki na graphite da kashi 10%, amma ana iya rage yawan amfani da na'urorin lantarki na graphite a kowace ton na ƙarfe na tanderun lantarki da 20-30% (sakamakon sakamako). amfani da wutar lantarki na yau da kullun).Tun da rufin abu ne mai karye, cermet abu ne mai karye, don haka guje wa karo lokacin amfani da shi, kuma kada ku sanya murfin ya karye.

2. Rage isar da iskar: Ya kamata a adana na'urorin lantarki na graphite a cikin busasshiyar wuri da babu iska don hana kamuwa da danshi da iska.Wannan zai taimaka hana oxidation.

3. Rage zafin aiki: Yin aiki da lantarki a ƙananan zafin jiki na iya rage yiwuwar iskar oxygenation.Ana iya samun wannan ta hanyar rage halin yanzu ko ƙara tazarar lantarki.

4. Amfani da iskar kariya: Ana iya amfani da iskar kariya kamar argon ko nitrogen yayin aiki don hana iskar oxygen.Gas yana taimakawa wajen haifar da yanayi mai karewa a kusa da lantarki.

5. Tsabtace mai kyau: Tsabtace na'ura mai kyau kafin aiki zai iya cire duk wani datti ko gurɓataccen abu wanda zai iya haifar da oxidation.

Iyakar aikace-aikace: dace da graphite kayayyakin kamar graphite lantarki, anode carbon tubalan, electrolytic aluminum shuke-shuke, graphite molds, graphite crucibles, da sauran graphite kayayyakin surface sealing anti-oxidation, sealing anti-lalata, tsawaita rayuwar graphite kayayyakin by a aƙalla 30%, ƙara ƙarfin kayan aiki.
