550mm amandla aphezulu e-electrode yegraphite
I-electrode yegraphite ye-HP yenziwe ikakhulu ngepetroleum coke kunye nenaliti yecoke, Iyakwazi ukuthwala ukuxinana kwangoku 18-25A/cm2. Yenzelwe ukwenza intsimbi yesithando sombane esinamandla aphezulu.
Iindlela zale mihla zokwenza intsimbi ikakhulu zibandakanya i-converter steelmaking kunye ne-electric furnace steelmaking. Umahluko osisiseko kakhulu phakathi kwendlela yokwenza insimbi yombane kunye nendlela yokwenza insimbi yokuguqula kukuba indlela yokwenza intsimbi yombane isebenzisa amandla ombane njengomthombo wobushushu, kwaye indlela yokwenza intsimbi yombane ye-arc yeyona isetyenziswa ngokuqhelekileyo.
I-EAF steelmaking isekelwe kwi-arc yombane eveliswa ngokukhutshwa phakathi kwe-electrode kunye nentlawulo, eguqula amandla ombane kumandla ombane kukukhanya kwe-arc, kwaye isebenzisa isenzo esithe ngqo semitha kunye ne-arc ukutshisa kunye nokunyibilika kwesinyithi kunye ne-slag ukunyibilika. intsimbi kunye ne-alloys yeengoma ezahlukeneyo.

Ukuqulunqwa kwe-electrode yegraphite
I-1.I-petroleum coke imnyama kwaye i-porous, i-carbon iyona nto iphambili, kwaye umxholo womlotha uphantsi kakhulu, ngokuqhelekileyo ungaphantsi kwe-0.5%.
I-petroleum coke inokohlulwa ibe ziindidi ezimbini zecoke ekrwada kunye necoke ene-calcined ngokobushushu bonyango lobushushu. Eyangaphambili iqulethe isixa esikhulu sezinto eziguquguqukayo kwaye inamandla aphantsi oomatshini. I-coke e-calcined ifunyanwa ngokufaka i-calcining i-coke eluhlaza.
I-petroleum coke inokohlulwa ibe yicoke ephezulu yesulfure (enomthamo wesulfure ngaphezulu kwe-1.5%), icoke yesulfure ephakathi (enomthamo wesulfure ngu-0.5% -1.5%), kunye necoke ephantsi yesulfure (enomthamo wesulfure ongaphantsi kwe-0.5%) ngokwezinga lesulfure. Iielectrode zegraphite kunye nezinye iimveliso zegraphite ezenziweyo ziveliswa ngokubanzi kusetyenziswa icoke yesulphur ephantsi.
I-2.I-needle coke luhlobo lwe-coke ephezulu kunye ne-fiber texture ebonakalayo, ngokukodwa i-coefficient ephantsi yokwandisa i-thermal kunye ne-graphitization elula. Ke ngoko, inaliti ye-coke sisixhobo esiphambili sokwenza i-electrode yegraphite yamandla aphezulu okanye i-ultra-high-power eboniswe ngokumelana okuphantsi, i-coefficient encinci yokwandisa i-thermal, kunye nokuxhathisa ukothuka kwe-thermal.
I-3.I-Coal pitch yenye yeemveliso eziphambili zetela yamalahle emva kokucubungula okunzulu. Ingumxube weehydrocarbon ezininzi. I-pitch yamalahle isetyenziswa njengesibophelelo kunye nemathiriyeli yokumithisa. Ukusebenza kwayo kunempembelelo enkulu kumgangatho we-graphite electrode.
