ZISETYENZISWA NJANI II-ELECTRODE ze-GRAPHITE KWI-EAF STELMAMENTS?

Ukusetyenziswa kwee-electrode zegraphite kunxulumene ikakhulu nomgangatho wee-electrode ngokwazo, kodwa nakwindlela yokwenza intsimbi kunye nenkqubo (efana noxinaniso lwangoku ngee-electrode, intsimbi yokunyibilikisa, umgangatho weentsimbi ezilahliweyo kunye nexesha le-oksijini yebhloko. ingxabano, njl.).

(1) Inxalenye ephezulu ye-electrode idliwe. Ukusetyenziswa kubandakanya i-sublimation yezinto zegraphite ezibangelwa ubushushu obuphezulu be-arc kunye nokulahleka kokusabela kweekhemikhali phakathi kwenxalenye yombane egqithisileyo kunye nentsimbi etyhidiweyo kunye ne-slag, kunye nokusetyenziswa kwenxalenye yombane egqithiseleyo kunxulumene nokuba i-electrode ifakwe kwintsimbi etyhidiweyo ukuya. carburize.

(2) Ukulahleka kwe-oxidation kwindawo yangaphandle ye-electrode. Kwiminyaka yakutshanje, ukuze kuphuculwe izinga lokunyibilika kwesithando sombane, ukusebenza ngokufutha ioksijini kudla ngokusetyenziswa, nto leyo ekhokelela ekwandeni kokulahleka kwe-electrode oxidation. Kwiimeko eziqhelekileyo, ilahleko ye-oxidation yendawo yangaphandle ye-electrode yenza malunga ne-50% yokusetyenziswa ngokupheleleyo kwe-electrode.

(3) Ukulahleka okushiyekileyo kwee-electrodes okanye amajoyina. Icandelo elincinci le-electrode okanye i-joint (okt, i-residu) esetyenziswa ngokuqhubekayo ukudibanisa i-electrode ephezulu kunye nesezantsi ilungele ukuwa kunye nokwandisa ukusetyenziswa.

I-electrode yegraphite

(4) Ukulahleka kwe-electrode breakage, i-peeling surface kunye neebhloko eziwayo. Ezi ntlobo zintathu zelahleko ze-electrode ngokudibeneyo zibizwa ngokuba yilahleko yomatshini, apho unobangela wokuqhekeka kwe-electrode kunye nokuwa yindawo ephikisanayo yomgangatho wengozi echongiweyo yintsimbi yokusila kunye nesixhobo sokuvelisa i-electrode yegraphite, ngenxa yokuba inokuba umgangatho kunye neengxaki zokucubungula i-electrode yegraphite (ingakumbi i-electrode joint), okanye ingaba yingxaki ekusebenzeni kwensimbi.

Ukusetyenziswa kwe-electrode okungenakuthintelwa okufana ne-oxidation kunye ne-sublimation kwiqondo lobushushu eliphezulu ngokuqhelekileyo kuthiwa "ukusetyenziswa kwe-net", kwaye "ukusetyenziswa kwe-net" kunye nelahleko yoomatshini efana nokwaphuka kunye nelahleko eseleyo ibizwa ngokuba "usetyenziso olugqithisileyo". Okwangoku, ukusetyenziswa okukodwa kwe-electrode yegraphite ngetoni yentsimbi yesithando sombane e-China yi-1.5 ~ 6kg. Kwinkqubo yokunyibilika kwentsimbi, i-electrode i-oxidized ngokuthe ngcembe kwaye idliwe kwi-cone. Ngokuqhelekileyo ukujonga i-taper ye-electrode kunye nobomvu bomzimba we-electrode kwinkqubo yokwenza intsimbi yindlela enembile yokulinganisa ukuxhathisa kwe-oxidation ye-graphite electrode.
