Coke ya petroleum yokhala ndi grafiti imawonjezera ubwino wa "majini" a chitsulo mwa kukonza kapangidwe ka kaboni, kuwongolera bwino kapangidwe kake, kukonza magwiridwe antchito a zitsulo, ndikukwaniritsa zofunikira za kupanga zinthu zapamwamba. Njira ndi zotsatira zake ndi izi:
I. Kukonza Kapangidwe ka Kaboni: Kudumpha Koyenera Kuchokera ku "Nthangala Yaikulu" Kupita ku "Mpunga Woyengedwa"
Zowonjezera za kaboni wamba (monga calcined coke) zimakhala ndi makonzedwe a atomu ya kaboni osakhazikika, omwe ali ndi kuchuluka kwa kuyamwa kwa 60%. Mosiyana ndi zimenezi, graphitized petroleum coke, yomwe imayikidwa kutentha kwambiri pa 2800℃, imapanga kapangidwe ka graphite kofanana ndi "makadi osewerera okhazikika." Kapangidwe kameneka kamathandiza kuti isungunuke mwachangu mu chitsulo chosungunuka, ndipo kuchuluka kwa kuyamwa kumakwera kufika pa 90%. Mwachitsanzo, posungunula chitsulo chonyamula (GCr15), kuchuluka kwa kaboni kuyenera kulamulidwa bwino mkati mwa 1.05%-1.15%. Kugwiritsa ntchito graphitized carbon additive kumatsimikizira kuti kuyamwa kwa kaboni kumakhala kokhazikika kwa 92%, ndipo kusinthasintha kwa kaboni sikupitirira ±0.02%, motero kumaletsa kusweka kwa brittle kapena kuuma kosakwanira kwa ma bearing chifukwa cha kusiyana kwa kaboni.
II. Malamulo Oyenera Opangira Zinthu: Kusintha "Ndondomeko ya Zakudya" ya Zitsulo Zapamwamba
- Kuchuluka Kochepa kwa Chidetso: Njira yopangira graphitization imasintha sulfure, nayitrogeni, ndi zinyalala zina kukhala mpweya womwe umasinthasintha, zomwe zimachepetsa kuchuluka kwa sulfure kufika pansi pa 0.05% ndi kuchuluka kwa nayitrogeni kufika pansi pa 0.01%. Mwachitsanzo, chitsulo cha silicon chomwe sichimayang'aniridwa chomwe chimagwiritsidwa ntchito m'nyumba zatsopano zamagalimoto chimafuna kuchuluka kwa kaboni pansi pa 0.005%, zomwe zimapangitsa kuti pakhale kugwiritsa ntchito zowonjezera za kaboni zokhala ndi graphitized high-purity. Mofananamo, ma alloy okhala ndi nickel a ma evaporators a nyukiliya ayenera kukhala ndi kuchuluka kwa nayitrogeni kosapitirira 0.01%, chofunikira chomwe zowonjezera za kaboni wamba sizingakwaniritse.
- Kuwongolera Kokhazikika kwa Kapangidwe: Mwa kusintha kuchuluka kwa chakudya ndi magawo a njira, kuchuluka kwa zinthu monga kaboni, sulfure, ndi nayitrogeni mu chitsulo chosungunuka kumatha kulamulidwa bwino. Mwachitsanzo, pakusungunuka kwa ng'anjo yamagetsi, coke ya petroleum yokhala ndi grafiti imawonjezedwa pamodzi ndi zitsulo zotsalira ndi zinthu zina zolipirira kuti apewe kukhuthala kwambiri komwe kumachitika chifukwa cha kudyetsa kwakukulu, kuonetsetsa kuti kuchuluka kwa kaboni mu zinthu zotayidwa kumakwaniritsa miyezo.
III. Kukonza Kugwiritsa Ntchito Bwino kwa Metallurgical: Kuchokera ku "Kusagaya bwino chakudya" mpaka "Kuyamwa Bwino"
- Kuchuluka kwa Kuchuluka kwa Mpweya wa Kaboni: Kuchuluka kwa mpweya woipa wa coke wopangidwa ndi graphitized petroleum kumakwera ndi 30% kuposa kwa zowonjezera wamba za kaboni, zomwe zikutanthauza kuti pa 10 jin iliyonse ya kaboni yowonjezeredwa, kuyamwa kwenikweni kumawonjezeka ndi 3 jin. Izi zimachepetsa kwambiri kutayika kwa kaboni panthawi ya ntchito ya zitsulo ndikuchepetsa ndalama zopangira.
- Kuchepetsa Kutulutsa Utsi Woipa: Makhalidwe otsika a sulfure ndi nayitrogeni a graphitized petroleum coke amachepetsa kutulutsa kwa sulfure dioxide ndi nitrogen oxides panthawi yosungunulira, zomwe zikugwirizana ndi zofunikira zosungira mphamvu ndi kuchepetsa kutulutsa. Mwachitsanzo, kugwiritsa ntchito graphitized petroleum coke kungachepetse kutulutsa kwa sulfure oxide m'mabizinesi achitsulo ndi zoposa 50%.
IV. Kukwaniritsa Zofunikira Zapamwamba Zopangira Zinthu: Kudumpha kuchoka pa "Nyumba Yamphamvu Yachitsulo" kupita ku "Mphamvu Yamphamvu Yachitsulo"
- Kuthandizira Kupanga Zinthu Zapamwamba: Graphitized petroleum coke ndi chinthu chofunikira kwambiri popanga chitsulo champhamvu cha imvi, chitsulo cha silicon chosalunjika, zitsulo zopangidwa ndi nickel, ndi zinthu zina zachitsulo zapamwamba. Mwachitsanzo, kupanga zinthu "zolimba" monga ma flange a wind turbine ndi mapaipi amagetsi a nyukiliya kumadalira kuyera kwake kwakukulu komanso kuchuluka kwa kuyamwa.
- Kupititsa patsogolo Kukweza Mafakitale: Pamene makampani opanga zitsulo ku China akusintha kupita ku chitukuko chapamwamba komanso chobiriwira, "kusintha kwa dziko" kwa coke ya petroleum yokhala ndi graphitized kukuchulukirachulukira. Kugwiritsa ntchito kwake sikungowonjezera ubwino wa zinthu zachitsulo komanso kumalimbikitsa kupita patsogolo kwaukadaulo mu unyolo wonse wa mafakitale. Mwachitsanzo, kampani yachitsulo inachepetsa kusinthasintha kwa kaboni kwa zitsulo zonyamula mpweya kuchokera ku ± 0.05% mpaka ± 0.02% pogwiritsa ntchito coke ya petroleum yokhala ndi graphitized, zomwe zinapangitsa kuti chiwerengero cha zinthu chiwonjezeke ndi 15%.
V. Maphunziro a Nkhani: Zotsatira za "Hardcore" za Graphitized Petroleum Coke
- Kupanga Zitsulo Zokhala ndi Zitsulo: Pambuyo pogwiritsa ntchito graphitized petroleum coke, kampani ina inachepetsa kusinthasintha kwa carbon kwa chitsulo chokhala ndi zitsulo kuchokera pa ± 0.05% kufika pa ± 0.02%, inawonjezera kuchuluka kwa zinthu zomwe zimayenera kugulitsidwa ndi 15%, ndipo inapulumutsa ma yuan opitilira 10 miliyoni omwe amatayika pachaka.
- Nyumba Zatsopano Zopangira Magalimoto Ogwiritsa Ntchito Mphamvu: Pogwiritsa ntchito petroleum coke yoyera kwambiri, kuchuluka kwa kaboni mu chitsulo cha silicon chomwe sichinayende bwino kunakhazikika pansi pa 0.005%, zomwe zinapangitsa kuti magalimoto azigwira bwino ntchito ndi 3% ndikuwonjezera kuchuluka kwa magalimoto ndi 5%.
- Zotulutsa Mphamvu za Nyukiliya: Kuchuluka kwa nayitrogeni mu zitsulo zopangidwa ndi nickel kunachepetsedwa ndi 0.01%, zomwe zinaletsa kuwonongeka kwa zinthu chifukwa cha kuchuluka kwa nayitrogeni ndikuwonjezera moyo wa zida ndi zaka 20.
