Yintoni iGraphite Electrode?

I-electrode yegraphiteluhlobo lwe-electrode esetyenziswa kwizicelo zombane zobushushu obuphezulu, ngakumbi ekuveliseni intsimbi ngenkqubo yombane ye-arc furnace (EAF).I-electrode yegraphite zizinto ezibalulekileyo kule ndlela yokwenza intsimbi, apho ziqhuba khona umbane wokunyibilikisa isinyithi esilahliweyo kunye nezinye izinto eziluhlaza.

Iielectrode zegraphite zihlala zenziwe ngomxube wepetroleum coke, i-pitch, kunye nezinye izinto zekhabhoni.Ezi zixhobo zixinzelelwe kwaye zibhaka ukwenza i-electrode.I-electrode yegraphite ephumayo ine-conductivity ephezulu yombane, ukumelana nobushushu obuphezulu, kunye namandla afanelekileyo omatshini, okwenza kube yinto efanelekileyo yokusetyenziswa kwiimeko ezigqithisileyo zesithando sombane se-arc.

Inkqubo yesithando somlilo we-arc yindlela eyaziwayo yokuvelisa intsimbi ngenxa yokuguquguquka kwayo kunye nokukwazi ukusebenzisa izinto ezahlukeneyo.Kule nkqubo, isinyithi esilahliweyo kunye nezinye izinto eziluhlaza ziyanyibilika kusetyenziswa ubushushu obuveliswe kwi-arc yombane phakathii-electrode yegraphitenentsimbi iyanyibilika.Umbane wombane udlula kwi-electrodes yegraphite, udala ukushisa okukhulu okunyibilikisa izinto, ukuvumela ukungcola ukuba kususwe kunye nezinto ezixutywayo zongezwa ukuvelisa ibakala lentsimbi elifunwayo.

Ii-electrode zegraphite ziza ngobukhulu obahlukeneyo kunye namabanga ukuhlangabezana neemfuno ezithile zezicelo ezahlukeneyo zokwenza intsimbi.Ububanzi kunye nobude be-electrodes bunokwahluka ngokuxhomekeke kumthamo kunye noyilo lwesithando sombane se-arc.Ukongezelela, umgangatho kunye nokubunjwa kwe-electrode yegraphite, kubandakanywa ubuninzi bayo kunye ne-thermal conductivity, idlala indima ebalulekileyo ekusebenzeni kakuhle kunye nokusebenza kwenkqubo yokwenza isinyithi.

Enye yezinto eziphambili ekusebenzeni kwee-electrode zegraphite kukumelana kwazo ne-oxidation kunye nokutshatyalaliswa kwe-thermal.Ngethuba lenkqubo yokwenza i-steelmaking, i-electrode yegraphite ibonakaliswe kubushushu obugqithisileyo kunye neekhemikhali.Ikhono le-electrodes ukumelana nezi meko ezinzima ngaphandle kokuwohloka kubalulekile ekugcineni ukusebenza okuzinzile nokuthembekileyo kwesithando sombane se-arc.

I-electrode yegraphite nayo idlala indima ebalulekileyo kwindleko iyonke kunye nokusebenza kakuhle kwamandla kwimveliso yentsimbi.Ngokubonelela ngokusebenza kakuhle kombane kunye nokuhanjiswa kobushushu, i-electrodes ephezulu yegraphite inegalelo ekunciphiseni ukusetyenziswa kwamandla kunye nokuphucula ukusebenza kokunyibilika kwesithando sombane se-arc.Oku, kunokukhokelela ekugcinweni kweendleko kunye neenzuzo zokusingqongileyo kwimisebenzi yokwenza intsimbi.

Ukongeza kusetyenziso lwazo oluphambili kwishishini lentsimbi, i-electrode yegraphite inezicelo kwezinye iinkqubo zobushushu obuphezulu, njengokuveliswa kwee-ferroalloys, isinyithi se-silicon, kunye nezinye izinto ezikhethekileyo.Ezi nkqubo nazo zixhomekeke kwiipropati zombane kunye ne-thermal ye-graphite electrode ukufezekisa iziphumo ezifunwayo.

Ngokubanzi, i-electrode yegraphite zizinto eziyimfuneko kwizicelo zombane ezinobushushu obuphezulu, ngakumbi kwi-steelmaking ngenkqubo yesithando sombane se-arc.Indibaniselwano yabo ekhethekileyo yokuhanjiswa kombane, ukumelana nobushushu, kunye namandla oomatshini kubenza babaluleke kakhulu ekunyibilikeni nasekusulungekiseni intsimbi kunye nezinye izinto.Njengoko imveliso yentsimbi iqhubeka nokuguquka, imfuno ye-electrode ye-graphite ephezulu kulindeleke ukuba ihlale iqinile, iqhube phambili ekubunjweni kwayo, ukusebenza kunye nokuzinza kwishishini le-steelmaking.
