Ukusetyenziswa kwee-Electrodes zeGraphite kunye nezinto eziluncedo

I-electrode ye-graphite ifumana ukusetyenziswa ngokubanzi kwishishini lentsimbi, apho isetyenziswe kwii-arc furnaces zombane (EAF) kwimveliso yentsimbi.Kwi-EAF,i-electrode yegraphitebaqeshelwe ukuthwala imisinga yombane ephezulu, evelisa ubushushu obuyimfuneko ekunyibilikiseni isinyithi esilahliweyo nokuyiguqula ibe yintsimbi engamanzi.Ubume begraphite obusebenza kakhulu buvumela ukuba imelane nobushushu obugqithisileyo obuveliswa ngexesha lale nkqubo.

Iielectrode zegraphite zineenzuzo ezintle ngolu hlobo lulandelayo:

I-thermal ephezulu kunye ne-conductivity yombane:

Le propati ibenza bakwazi ukujamelana namaqondo okushisa aphezulu kwaye baphathe umthamo omkhulu wombane ngaphandle kokuthotywa okukhulu.Ii-electrode zidlala indima ebalulekileyo ekugqithiseni amandla ngokufanelekileyo, okukhokelela kwimveliso ephezulu kunye nokusetyenziswa kwamandla okuphantsi.

Amandla omatshini agqwesileyo kunye nokuxhathisa ukothuka kwe-thermal:

Ezi zakhiwo zenza ukuba zibe namandla kakhulu kwaye zikwazi ukunyamezela iimeko ezifunekayo ngaphakathi kwesithando sombane se-arc.Ikhono lokumelana nokutshitshiswa kwe-thermal kuqinisekisa ukuba i-electrode ayiqhekezi okanye iphule ngexesha lenkqubo yokwenza insimbi, ekhokelela kubomi obude kunye nokunciphisa ixesha lokuvelisa.

I-coefficient ephantsi yokwandiswa kwe-thermal:

Olu phawu lubavumela ukuba bandise kwaye banciphe ngokufanayo xa bevezwe kwiinguqu zeqondo lokushisa, ukunciphisa amathuba okuqhekeka okanye ukuphuka.Uzinzo olunikezwa ngama-electrode egraphite luqinisekisa ukusebenza okuhambelanayo kwaye kwenza ukuba abavelisi bentsimbi bafezekise ulawulo oluchanekileyo kuyo yonke inkqubo yokunyibilika.

Ukunganyangeki ngamachiza:

Oku kubenza basebenze kwiinkqubo ezahlukeneyo zeekhemikhali kunye ne-electrochemical.Ukuchasana kwabo kwiindawo ezinobungozi kunye neekhemikhali zivimbela i-electrode ukuba iyancipha, iqinisekisa ukusebenza okuqhubekayo kwiimeko ezinzima.Oku kuguquguquka kwandisa intsimi yezicelo zee-electrode zegraphite ngaphaya koshishino lwentsimbi.

Indawo intle:

Ngexesha le-steelmaking process, i-electrodes ayivelisi nayiphi na igesi okanye imveliso eyingozi.Lo mba uhambelana nokukhula kwehlabathi jikelele kugxininiso lokuzinza kunye nokunciphisa i-carbon footprint yoshishino lwentsimbi.

I-electrode yegraphite yinxalenye ebalulekileyo kwishishini lentsimbi, ibonelela ngeenzuzo ezininzi ngokwemigaqo yobushushu kunye nokuhanjiswa kombane, amandla oomatshini, kunye nokuxhathisa imichiza.Ukukwazi kwabo ukumelana namaqondo obushushu agqithisileyo, ukuxhathisa ukothuka kwe-thermal, kunye nokugcina uzinzo kubenza babaluleke kakhulu kwimveliso yentsimbi esebenzayo.Ukongeza, ubuhlobo babo bokusingqongileyo buhambelana nezenzo ezizinzileyo ezamkelwa ngamashishini kwihlabathi liphela.Ngenkqubela phambili eqhubekayo kubuchule bokuvelisa, i-electrode yegraphite iyaqhubeka nokuguquka njengesixhobo esibalulekileyo kwiinkqubo zanamhlanje zokwenza intsimbi.
