I-graphitized petroleum coke ithuthukisa ikhwalithi "yofuzo" yensimbi ngokuphelele ngokwenza ngcono isakhiwo sekhabhoni, ukulawula ngokunembile ukwakheka, ukuthuthukisa ukusebenza kahle kwensimbi, kanye nokuhlangabezana nezidingo zokukhiqiza okuphezulu. Izindlela nemiphumela ethile yilena elandelayo:
I. Ukuthuthukisa Isakhiwo Sekhabhoni: Ukugxuma Okusezingeni Elifanele Kusukela “Kusanhlamvu Okukhulu” Kuya “Kulayisi Elicwengekile”
Izithasiselo zekhabhoni ezijwayelekile (njenge-calcined coke) zinezinhlelo ze-athomu yekhabhoni eziphazamisekile, ngesilinganiso sokumuncwa esingu-60%. Ngokuphambene nalokho, i-graphitized petroleum coke, ephathwa ngokushisa okuphezulu ku-2800℃, yakha isakhiwo esijwayelekile esinezingqimba ze-graphite esifana "namakhadi okudlala ahlanganisiwe." Lesi sakhiwo siyenza ikwazi ukuncibilika ngokushesha ensimbini encibilikisiwe, kanti izinga lokumuncwa likhuphuka lize lifike ngaphezu kuka-90%. Isibonelo, lapho kuncibilikiswa insimbi ethwala insimbi (GCr15), okuqukethwe kwekhabhoni kumele kulawulwe ngokunembile ngaphakathi kobubanzi obungu-1.05%-1.15%. Ukusebenzisa isithasiselo sekhabhoni esine-graphitized kuqinisekisa izinga lokumuncwa elizinzile elingu-92%, kanye nokuguquguquka kokuqukethwe kwekhabhoni okungadluli ku-±0.02%, ngaleyo ndlela kuvimbele ukuphuka okubuthakathaka noma ukuqina okunganele kwama-bearings okubangelwa ukuphambuka kokuqukethwe kwekhabhoni.
II. Umthetho Wokwakheka Okunembile: Ukwenza Ngokwezifiso “Uhlelo Lokudla” Lwensimbi Esezingeni Eliphezulu
- Okuqukethwe Okungcolile Okuphansi: Inqubo ye-graphitization iguqula i-sulfur, i-nitrogen, kanye nokunye ukungcola kube amagesi ashintshashintshayo, okunciphisa okuqukethwe kwe-sulfur kube ngaphansi kuka-0.05% kanye nokuqukethwe kwe-nitrogen kube ngaphansi kuka-0.01%. Isibonelo, insimbi ye-silicon engaqondiswanga esetshenziswa ezindlini zezimoto ezintsha zamandla idinga okuqukethwe kwe-carbon okungaphansi kuka-0.005%, okudinga ukusetshenziswa kwezithasiselo ze-carbon ezihlanjululwe kakhulu. Ngokufanayo, ama-alloy asekelwe ku-nickel kuma-evaporators amandla enuzi kumele abe nokuqukethwe kwe-nitrogen okungadluli ku-0.01%, isidingo izithasiselo ze-carbon ezivamile ezingenakukwazi ukusifinyelela.
- Ukulawulwa Kokwakheka Okuzinzile: Ngokulungisa inani lokuphakelwa kanye nemingcele yenqubo, okuqukethwe kwezinto ezifana nekhabhoni, isibabule, kanye ne-nitrogen ensimbini encibilikisiwe kungalawulwa ngokunembile. Isibonelo, ekuncibilikeni kwesithando sikagesi, i-graphitized petroleum coke ingezwa kanye nensimbi eqoshiwe kanye nezinye izinto zokushaja ukuze kugwenywe ukungcoliswa ngokweqile okubangelwa ukondla okukhulu, okuqinisekisa ukuthi okuqukethwe kwekhabhoni kokuphonswa kuhlangabezana nezindinganiso.
III. Ukuthuthukisa Ukusebenza Kahle Kwensimbi: Kusukela “Ekugayweni Okungagaywa” Kuya “Ekumuncweni Okusebenzayo”
- Izinga Lokumuncwa Kwekhabhoni Elikhuphukile: Izinga lokumuncwa kwekhabhoni le-graphitized petroleum coke liphakeme ngamaphesenti angaphezu kwama-30 kunelezithasiselo zekhabhoni ezivamile, okusho ukuthi kuzo zonke izi-10 zekhabhoni ezingeziwe, ukumuncwa kwangempela okuphumelelayo kuyanda ngama-3 jin. Lokhu kunciphisa kakhulu ukulahlekelwa yikhabhoni ngesikhathi senqubo yensimbi futhi kunciphisa izindleko zokukhiqiza.
- Ukukhishwa Okungcolile Okuncishisiwe: Izici eziphansi zesulfure ne-nitrogen ze-graphitized petroleum coke zinciphisa ukukhishwa kwe-sulfur dioxide kanye ne-nitrogen oxides ngesikhathi sokuncibilikisa, okuhambisana nezidingo zokulondolozwa kwamandla kanye nokunciphisa ukukhishwa. Isibonelo, ukusetshenziswa kwe-graphitized petroleum coke kunganciphisa ukukhishwa kwe-sulfur oxide emabhizinisini ensimbi ngaphezu kuka-50%.
IV. Ukuhlangabezana Nezidingo Zokukhiqiza Ezisezingeni Eliphezulu: Ukugxuma Kusuka “Esigungwini Esinamandla Sensimbi” Kuya “Esinamandla Kakhulu Sensimbi”
- Ukusekela Ukukhiqizwa Komkhiqizo Osezingeni Eliphezulu: I-graphitized petroleum coke iyinto ebalulekile yokukhiqiza insimbi empunga enamandla amakhulu, insimbi ye-silicon engagxilile, ama-alloy asekelwe ku-nickel, kanye neminye imikhiqizo yensimbi ephezulu. Isibonelo, ukukhiqizwa kwemikhiqizo "eqinile" njenge-wind turbine flanges kanye namapayipi amandla enuzi kuncike ekuhlanzekeni kwayo okuphezulu kanye nezici zezinga lokumuncwa eliphezulu.
- Ukuthuthukisa Izimboni: Njengoba imboni yensimbi yaseShayina ishintsha iye ekuthuthukisweni okuphezulu nokuluhlaza, "ukufakwa esikhundleni kwe-coke kaphethiloli e-graphitized kuyanda. Ukusetshenziswa kwayo akugcini nje ngokuthuthukisa ikhwalithi yemikhiqizo yensimbi kodwa futhi kukhuthaza intuthuko kwezobuchwepheshe kulo lonke uchungechunge lwezimboni. Isibonelo, ibhizinisi lensimbi linciphise uhla lokuguquguquka kokuqukethwe kwekhabhoni kwensimbi ethwala kusuka ku-±0.05% kuya ku-±0.02% ngokusebenzisa i-coke kaphethiloli e-graphitized, okuholele ekukhuleni okungu-15% kwesilinganiso sokufaneleka komkhiqizo.
V. Izifundo Zezimo: Imiphumela “Eqinile” Ye-Graphitized Petroleum Coke
- Ukukhiqizwa Kwensimbi Ethwala Izinsimbi: Ngemva kokusebenzisa i-graphitized petroleum coke, ibhizinisi elithile lehlisa uhla lokuguquguquka kokuqukethwe kwekhabhoni kwensimbi ethwala izinsimbi kusukela ku-±0.05% kuya ku-±0.02%, landisa izinga lokufaneleka komkhiqizo ngo-15%, futhi lasindisa ama-yuan angaphezu kwezigidi eziyishumi ekulahlekelweni kwezinsalela zonyaka.
- Izindlu Zezimoto Ezintsha Ezinamandla: Ngokusebenzisa i-coke kaphethiloli ehlanjululwe nge-graphitized, okuqukethwe kwekhabhoni kwensimbi ye-silicon engaqondiswanga kwaqiniswa ngaphansi kuka-0.005%, kwathuthukisa ukusebenza kahle kwezimoto ngo-3% futhi kwandisa ububanzi bokushayela ngo-5%.
- Ama-Evaporator Amandla Enuzi: Okuqukethwe kwe-nitrogen kuma-alloy asekelwe ku-nickel kwalawulwa ngaphansi kuka-0.01%, okuvimbela ukuqhekeka kwezinto okubangelwa okuqukethwe kwe-nitrogen ngokweqile nokwandisa impilo yenkonzo yemishini ngeminyaka engama-20.
