400 UHP graphite electrode
Iielectrode zegraphite zisetyenziswa ikakhulu kwinkqubo yokwenza intsimbi. Intsimbi yentsimbi iyanyibilika kwiziko le-arc yombane kwaye iyarisayikilishwa. Njengohlobo lomqhubi, bayinxalenye ebalulekileyo kolu hlobo
I-electrode ye-graphite ye-UHP yenziwe ikakhulu nge-coke yenaliti ekumgangatho ophezulu, kwaye isetyenziswa kakhulu kwii-arc furnaces zombane zamandla aphezulu.

Inkqubo yokuvelisa
I-electrode yegraphite yenziwa ikakhulu ngepetroleum coke kunye nenaliti yecoke, exutywe nepitch yamalahle, ukungena kwiinkqubo zokubala, ukuxova, ukwenza, ukubhaka, igraphitizing kunye nomatshini, ekugqibeleni ibe zimveliso. Nazi ezinye iinkcazo zenkqubo yemveliso:
Ukuxova: Ukuxuba kunye nokuxuba umlinganiselo othile we-carbon particles kunye nomgubo kunye nomlinganiselo othile we-binder kubushushu obuthile, le nkqubo ibizwa ngokuba kukuxova.
Umsebenzi wokuxova
① Xuba zonke iintlobo zemathiriyeli ekrwada ngokulinganayo, kwaye kwangaxeshanye wenze izinto eziqinileyo zekhabhoni zobungakanani bamasuntswana ahlukeneyo ngokulinganayo udibanise kwaye ugcwalise, kwaye uphucule ukuxinana komxube;
②Emva kokongeza i-asphalt yamalahle, fumana yonke imathiriyeli ngokuqinileyo kunye.
③Eminye imingxuma yamalahle ingena kwi-voids yangaphakathi, ephucula ngakumbi ukuxinana kunye nokuncamathela kwencama.
Ukubumba: Intlama yekhabhoni ephothiweyo ikhutshelwa emzimbeni oluhlaza (okanye imveliso eluhlaza) enemilo ethile, ubungakanani, ubuninzi kunye namandla kwisixhobo sokubumba. I-paste ine-deformation yeplastiki phantsi kwamandla angaphandle.
Ukuqhotsa kukwabizwa ngokuba kukubhaka, Lunyango lobushushu obuphezulu, okwenza i-coke pitch ifakwe kwi-coke, edibanisa i-carbonaceous aggregates kunye namasuntswana omgubo kunye namandla omatshini aphezulu, ukuxhathisa okuphantsi, ukuzinza okungcono kwe-thermal kunye nokuzinza kweekhemikhali.
I-roasting yesibini kukubhaka elinye ixesha, ukwenza i-pitch yokungena ifakwe i-carbonized. I-Electrodes (zonke iintlobo ngaphandle kwe-RP) kunye neengono ezifuna ubuninzi bobuninzi obuphezulu kufuneka zibhakwe okwesibini, kunye neengono ezintathu-dip ezine-bake okanye ezimbini-dip ezintathu-bake.
