Inkinga Yokuqala: “I-Cinderella” Yemboni Yokucwenga Uwoyela
Ingemuva: Ekuqaleni kwekhulu lama-20, ngokusetshenziswa kabanzi kobuchwepheshe bokuqhekeka uwoyela ongahluziwe, izindawo zokuhlanza uwoyela zakhiqiza inani elikhulu lemikhiqizo ebangela izinkinga—i-petroleum coke. Yayibhekwa “njengezinsalela ezisezingeni eliphansi kakhulu” ezinenani eliphansi kakhulu lokusetshenziswa.
Ukusetshenziswa Kokuqala: Izindawo zayo eziyinhloko zokukhipha uphethiloli zazisebenza njengophethiloli oshibhile (wokukhiqiza ugesi kanye nezitshalo zesimende) noma njengezinto zokusetshenziswa eziyinhloko zokukhiqiza ama-electrode e-carbon (njenge-anode esetshenziswa ekuncibilikiseni i-aluminium). Ngalesi sikhathi, ikhwalithi yayo yayihlukahluka kakhulu, futhi yayibhekwa njengento "engacwengekile futhi engahlelekile".
I-Catalyst of War: Ukuvela Kokwenza Insimbi Yesithando Somlilo Sikagesi
Iphuzu Elibalulekile Lokuguquka: Ngesikhathi seMpi Yezwe II, ubuchwepheshe bokwenza insimbi ye-arc furnace (EAF) bathuthukiswa ngokushesha. Isidingo sezinsimbi ezikhethekile ezisebenza kahle sanda ngesikhathi sempi. Ingxenye eyinhloko ye-EAF yi-electrode, edinga ukumelana namazinga okushisa e-arc kagesi afinyelela ku-3000°C futhi ibe nokuqhuba kahle kukagesi.
Inkinga Yezinto Ezibalulekile: Ama-electrode e-carbon ajwayelekile ahluleka ukuhlangabezana nezidingo. Ayethambekele ekushisweni yi-oxidation, ayenesilinganiso sokusetshenziswa okusheshayo, kanye nokusebenza kahle okuphansi. Abantu baqaphela ukuthi kwakudingeka ukuthuthukisa ubumsulwa kanye nesakhiwo sekristalu sezinto zokusetshenziswa ze-electrode.
Isingeniso se-"Graphitization": Kulesi sigaba, ubuchwepheshe be-"graphitization", obuvela ekusungulweni kuka-Edward G. Acheson kwe-graphite yokwenziwa ngasekupheleni kwekhulu le-19, basetshenziswa ku-petroleum coke. Kwatholakala ukuthi i-petroleum coke yaphathwa ngokushisa okuphezulu ngaphezu kuka-2500°C yathuthuka kakhulu ekusebenzeni, ihambisana kahle nezidingo zama-electrode e-EAF. Lokhu kwaba uphawu lokuqala lokuguquka okuyisisekelo esiphethweni se-petroleum coke—ukuthuthukiswa kwayo kusuka kuphethiloli kuya ku-consumable ebalulekile yezimboni.
Isisekelo Semboni: Ukusebenzisana Nemboni Ye-Aluminium
Ubudlelwano be-Symbiotic: Ngemva kwempi, ngesikhathi sokuvuselelwa komnotho womhlaba wonke, imboni ye-aluminium yabhekana nokukhula okusheshayo. Iseli le-electrolytic le-Hall-Héroult lokukhiqiza i-aluminium yensimbi lalidinga inani elikhulu lama-anode abhakiwe kusengaphambili, kanti i-petroleum coke esezingeni eliphezulu (ikakhulukazi i-"green coke" ene-sulfur ephansi) yayiyiyona kanye into eluhlaza eyinhloko.
Ukukhula Okuqhutshwa Yisidingo: Isidingo esikhulu esivela embonini ye-aluminium sazinzisa imakethe ye-petroleum coke futhi sakhuthaza ucwaningo olujulile ngekhwalithi ye-petroleum coke (njengokuqukethwe kwe-sulfur, ukungcola kwensimbi, kanye ne-thermal expansion coefficient), sabeka isisekelo esiqinile sezimboni sezinhlelo zokusebenza ze-graphitization ezalandela.
