Indlela yokuthintela i-oxidation yee-electrode zegraphite ngexesha lentsimbi.I-electrode ye-graphite isetyenziselwa i-arc metallurgy njengezinto eziphathekayo ezisetyenziswayo, kwaye iindleko zabo zokusetyenziswa zibandakanya malunga ne-10-15% yeendleko ze-steelmaking yesithando sombane.

Kwiminyaka yakutshanje, ukuze kuphuculwe imveliso yeziko lombane kunye nokunciphisa ukusetyenziswa kwamandla, iziko lombane liye lamkela imisebenzi yomthwalo ophezulu, kwaye ukusetyenziswa kwe-oxidation ye-electrode surfaces kudla ngokunyuka, ngaloo ndlela kwandisa ukusetyenziswa kwe-electrode kunye neendleko zokunyibilikisa. wenza i-oxidize i-electrode yegraphite

I-electrode ye-graphite inokukhuselwa kwi-oxidation ngokusebenzisa i-coating yokukhusela ebusweni be-electrode.Nazi ezinye iindlela zokuthintela i-oxidation yee-electrode zegraphite:

1. Okokuqala, isangqa segrooves enzulu senziwa kumphezulu we-electrode yegraphite, injongo kukwenza umaleko we-cermet unokubambelela ngokuqinileyo kumphezulu we-electrode yegraphite, emva koko i-electrode yegraphite ifudunyezwe malunga ne-250 ℃. isithando somlilo, kwaye emva koko i-metal spray gun isetyenziswe kwi-electrode.Kumphezulu, fafaza umaleko obhityileyo we-aluminiyam, utshize omnye umaleko we-cermet slurry kwi-aluminium layer, kwaye usebenzise i-carbon arc ukutshiza i-slurry, ukutshiza i-slurry kunye ne-arc sinter, phinda amaxesha angama-2-3 ukwenza i-cermet. ubukhulu obaneleyo.

I-resistiveivity ye-cermet yi-0.07-0.1pm, ephantsi kune-graphite electrode.Kwi-900 ℃ ye-50h, irhasi ayinamanzi kwaye iqondo lokushisa lokubola liyi-1750-1800 ℃.Ukubunjwa kwento yokwambathisa ayinayo impembelelo kwintsimbi etyhidiweyo.Ukwandisa izinto eziluhlaza, umbane kunye nomsebenzi osetyenziswa kwi-anti-oxidation coating iya kwandisa ixabiso le-electrode yegraphite nge-10%, kodwa ukusetyenziswa kweyunithi ye-graphite electrode ngetoni yentsimbi yombane yomlilo kunokunciphisa ngama-20-30% (isiphumo yokusetyenziswa kwiziko lombane eziqhelekileyo).Ekubeni iingubo ziyi-brittle material, i-cermet yinto enqabileyo, ngoko ugweme ukungqubana xa uyisebenzisa, kwaye ungenzi ukuba i-coating iqhawule.

2. Ukunciphisa i-exposure emoyeni: I-electrode ye-graphite kufuneka igcinwe kwindawo eyomileyo kunye ne-air-free ukuze kuthintelwe ukuvezwa kokufuma kunye nomoya.Oku kuya kunceda ukuthintela i-oxidation.

3. Ukunciphisa ubushushu bokusebenza: Ukusebenzisa i-electrode kwiqondo eliphantsi lobushushu kunokunciphisa amathuba okuba ne-oxidation.Oku kunokufezekiswa ngokunciphisa okwangoku okanye ukwandisa isithuba se-electrode.

4. Ukusebenzisa igesi ekhuselayo: Igesi yokukhusela efana ne-argon okanye i-nitrogen ingasetyenziselwa ngexesha lokusebenza ukukhusela i-oxidation.Igesi inceda ukudala umoya okhuselayo ojikeleze i-electrode.

5. Ukucoca ngokufanelekileyo: Ukucocwa ngokufanelekileyo kwe-electrode ngaphambi kokusebenza kunokususa nakuphi na ukungcola okanye ukungcola okunokubangela i-oxidation.

Ububanzi besicelo: Ifanelekile kwiimveliso zegraphite ezifana ne-graphite electrode, i-anode carbon blocks, izityalo ze-aluminiyamu ye-electrolytic, i-graphite molds, i-graphite crucibles, kunye nezinye iimveliso zegraphite ezitywina umphezulu wokulwa ne-oxidation, ukutywinwa kwe-anti-corrosion, ukwandisa ubomi beemveliso zegraphite ubuncinane 30%, ukwandisa amandla eziphathekayo.
