ASETSHENZISWA KANJANI AMA-ELECTRODE E-GRAPHITE EKWENZIWENI KWE-EAF STEELMAK?

Ukusetshenziswa kwama-electrode e-graphite kuhlobene kakhulu nekhwalithi yama-electrode ngokwawo, kodwa futhi nokusebenza kwensimbi nenqubo (njengokuminyana kwamanje ngama-electrode, insimbi encibilikayo, ikhwalithi yensimbi eyizinsimbi kanye nobude besikhathi komoyampilo we-block. ukungqubuzana, njll.).

(1) Ingxenye ephezulu ye-electrode idliwe. Ukusetshenziswa kuhlanganisa i-sublimation yezinto ze-graphite ezibangelwa izinga lokushisa eliphezulu le-arc kanye nokulahlekelwa ukusabela kwamakhemikhali phakathi kwengxenye kagesi eyedlulele nensimbi encibilikisiwe ne-slag, futhi ukusetshenziswa kwengxenye kagesi eyedlulele kuhlobene nokuthi i-electrode ifakwe ensimbi encibilikisiwe ukuze carburize.

(2) Ukulahlekelwa kwe-oxidation endaweni yangaphandle ye-electrode. Eminyakeni yamuva, ukuze kuthuthukiswe izinga lokuncibilika kwesithando somlilo kagesi, umsebenzi wokufutha umoya-mpilo uvame ukusetshenziswa, okuholela ekwandeni kokulahlekelwa kwe-electrode oxidation. Ngaphansi kwezimo ezijwayelekile, ukulahlekelwa kwe-oxidation kwendawo yangaphandle ye-electrode kubala cishe u-50% wengqikithi yokusetshenziswa kwe-electrode.

(3) Ukulahlekelwa okusele kwama-electrode noma amalunga. Ingxenye encane ye-electrode noma ijoyinti (okungukuthi, insalela) esetshenziswa ngokuqhubekayo ukuxhuma ama-electrode aphezulu naphansi ijwayele ukuwa futhi yandise ukusetshenziswa.

I-electrode ye-graphite

(4) Ukulahleka kokuphuka kwama-electrode, ukuxebuka kwendawo kanye namabhulokhi awayo. Lezi zinhlobo ezintathu zokulahlekelwa kwe-electrode zihlangene zibizwa ngokuthi ukulahlekelwa kwemishini, lapho imbangela yokuphuka nokuwa kwe-electrode iyindawo eyimpikiswano yengozi yekhwalithi ekhonjwe umshini wokugaya insimbi kanye nesikhungo sokukhiqiza i-graphite electrode, ngoba kungenzeka ukuthi kungenxa ikhwalithi nokucubungula izinkinga ze-graphite electrode (ikakhulukazi i-electrode joint), noma kungase kube inkinga ekusebenzeni kwensimbi.

Ukusetshenziswa okungagwemeki kwama-electrode okufana ne-oxidation kanye ne-sublimation ezingeni lokushisa eliphezulu ngokuvamile kubizwa ngokuthi “ukusetshenziswa kwenethi”, futhi “ukusetshenziswa kwenethi” kanye nokulahlekelwa komshini okufana nokuphuka nokulahlekelwa okuyinsalela kubizwa ngokuthi “ukusetshenziswa okuphelele”. Njengamanje, ukusetshenziswa okukodwa kwe-graphite electrode ngethani lensimbi yesithando somlilo kagesi e-China yi-1.5 ~ 6kg. Enqubweni yokuncibilika kwensimbi, i-electrode kancane kancane i-oxidized futhi idliwe ibe ikhoni. Ngokuvamile ukubheka i-taper ye-electrode kanye nokubabomvu komzimba we-electrode ngesikhathi sokwenza insimbi kuyindlela enembile yokukala ukumelana ne-oxidation ye-graphite electrode.
