Kutheni ii-electrode ze-graphite ezinamandla aphezulu kakhulu zibiza kakhulu?

Ixabiso eliphezulu lee-electrodes ze-graphite ezinamandla aphezulu kakhulu livela kakhulu kwiindleko zazo eziphezulu zezinto ezikrwada, iinkqubo zemveliso ezintsonkothileyo, iingenelo ezibalulekileyo zokusebenza, kunye ne-supply-demand dynamics. Uhlalutyo oluneenkcukacha lulandelayo:

1. Iindleko eziphezulu zezinto eziluhlaza
   Izinto eziphambili ezisetyenziswa kwi-electrodes ze-graphite ezinamandla aphezulu yi-needle coke kunye ne-petroleum coke, apho i-needle coke iyeyona nto ibalulekileyo. I-Needle coke ine-fibrous texture, i-low thermal expansion coefficient, kunye nokulula kwe-graphitization, okwenza ukuba ibe yinto efanelekileyo yokwenza ii-electrodes ze-graphite ezinamandla aphezulu okanye aphezulu kakhulu. Nangona kunjalo, inkqubo yayo yemveliso iyinkimbinkimbi, inemiqobo ephezulu yobuchwephesha, kwaye ukunikezelwa kwehlabathi kuhlala kuncinci, okubangela amaxabiso aphezulu rhoqo. Ukongeza, i-petroleum coke, enye into ebalulekileyo esetyenziswa kwi-raw, ichaphazeleka yi-dynamics yemfuno yokunikezelwa kwemarike kunye nokuguquguquka kwamaxabiso eoli ekrwada, kunye namaxabiso anyuka kwiminyaka yakutshanje. Ezi ndleko zikhulayo zezinto ezisetyenziswa kwi-raw zinyusa ngokuthe ngqo iindleko zemveliso yee-electrodes ze-graphite ezinamandla aphezulu kakhulu.

2. Iinkqubo zeMveliso ezintsonkothileyo
   Ukuveliswa kwee-electrode ze-graphite ezinamandla aphezulu kakhulu kubandakanya amanqanaba amaninzi, kuquka i-calcination yezinto eziluhlaza, ukuxuba, ukubumba, ukubhaka, ukufunxa, i-graphitization, kunye nomatshini wokugaya. Inyathelo ngalinye lifuna ulawulo oluqinileyo lweeparamitha zenkqubo ukuqinisekisa umgangatho wemveliso. I-Graphitization, inqanaba elibalulekileyo, lifuna unyango kumaqondo obushushu angaphezulu kwama-2,000°C ukuguqula isakhiwo sezinto zekhabhoni zibe ziikristale ze-graphite, ukuphucula ukuhanjiswa kombane kunye nokumelana nobushushu obuphezulu. Le nkqubo ayisebenzisi nje amandla kuphela kodwa ikwafuna utyalo-mali olukhulu kwizixhobo, nto leyo enyusa iindleko zemveliso ngakumbi.

3. Iingenelo ezibalulekileyo zokusebenza
   Ii-electrode zegrafiti ezinamandla aphezulu kakhulu zibonisa iimpawu ezibalaseleyo, ezinje ngokuxhathisa okuphantsi, uxinano oluphezulu, ukumelana ne-oxidation, ukunyamezelana nobushushu obuphezulu, kunye nokusetyenziswa okuphantsi. Ukuxhathisa kwazo kudla ngokuba phakathi kwe-4-6 μΩ·m, okuvumela ukuba umbane usebenze kakuhle kwii-oven zombane ukuze kuveliswe ubushushu obaneleyo bokunyibilikisa nokucoca isinyithi. Xa kuthelekiswa nee-electrode zamandla aqhelekileyo kunye nee-graphite ezinamandla aphezulu, iintlobo zamandla aphezulu kakhulu zinokumelana noxinano oluphezulu lwamandla, zinciphise ixesha lokunyibilikisa isinyithi esilahliweyo, zinciphise ukusetyenziswa kombane, kwaye ziphucule ukusebenza kakuhle kwemveliso. Ezi nzuzo zokusebenza ziqhuba ukusetyenziswa kwazo ngokubanzi ekwenzeni intsimbi, ukuvelisa i-phosphorus etyheli, ukunyibilikisa i-silicon kwimizi-mveliso, nakwamanye amacandelo, okunyusa imfuno yemarike eqinileyo.

4. Iinguqu zeMfuno yoNikezelo
   Kwiminyaka yakutshanje, ukuphinda kuvele ishishini lentsimbi kwihlabathi liphela kunye nokukhula ngokukhawuleza kumacandelo amatsha amandla kunye nezinto eziphambili kuye kwakhuthaza ukwanda kwemfuno yee-electrode ze-graphite ezinamandla aphezulu kakhulu. Nangona kunjalo, ngenxa yokunqongophala kobonelelo lwezinto eziluhlaza kunye neenkqubo zemveliso ezinzima, ukukhula kwemveliso kuye kwaba nzima kakhulu, okwandisa uxinzelelo lwemfuno yobonelelo. Ngokuchasene nale meko, amaxabiso ee-electrode ze-graphite ezinamandla aphezulu kakhulu anyukile ngokwemvelo.
