Imboni yensimbi imi njengomgogodla wengqalasizinda yomhlaba wonke, kodwa isebenza kwenye yezindawo ezinokushisa okuphezulu kakhulu eMhlabeni. Kusukela ekushiseni okunamandla kokuncibilika kwensimbi kuya ekunembeni kokusakazwa kwensimbi, izinto ezisetshenziswayo ezibalulekile njengeziguquli, izithando zomlilo zikagesi, neziqhumane zomlilo zibhekana nengcindezi engapheli: kumele zibekezelele ukuchayeka njalo emazingeni okushisa avame ukudlula ku-1,600°C, kubhangqwe nokuguguleka okunamandla okuvela kunsimbi encibilikisiwe ne-scalding. Lezi zimo ezimbi kakhulu zibeka izimfuno ezingenakuqhathaniswa ezintweni eziphikisayo - izendlalelo ezivikelayo ezivikela imishini emonakalweni - naphakathi kwazo zonke izinketho,izitini ze-magnesium-chromiumkuvela njengesixazululo esiphezulu, esithembekile
Izitini ze-Magnesium-chromium zikweleta isikhundla sazo esingenakuqhathaniswa embonini yensimbi ezintweni ezintathu ezibalulekile, ezingenakunqotshwa ezibhekana nazo zonke izindawo ezibuhlungu zokukhiqiza insimbi enezinga eliphezulu lokushisa. Okokuqala, ukumelana kwazo nomlilo okukhethekile kuyisiguquli sokuphepha nokusebenza kahle: ngesilinganiso se-refractoriness esingaphezu kuka-1,700°C, lezi zitini zigcina ubuqotho bazo besakhiwo ngisho nasezinkambeni ezishisa kakhulu zeziko lokwenza insimbi. Ngokungafani nezinto ezincibilika ezisezingeni eliphansi ezingase zithambe noma zincibilike ngaphansi kokushisa okukhulu, izitini ze-magnesium-chromium zisusa ubungozi bokungasebenzi kungazelelwe kwemishini, okungase kumise imigqa yokukhiqiza futhi kuholele ekubambezelekeni okubizayo. Okwesibili, ukumelana kwabo okuphezulu kwe-slag kubhekana ngqo nenselelo enkulu yokulungisa imboni yensimbi. Zakhiwe nge-high-purity magnesium oxide ne-chromium oxide, lezi zitini zakha umgoqo ominyene, ongangeneki oxosha kokubili ama-slags ane-alkaline ne-asidi—imikhiqizo evamile yokukhiqizwa kwensimbi edla ulwelwesi oluvamile. Lokhu kumelana kwandisa kakhulu ukuphila kolayini beziko ngo-30% noma ngaphezulu uma kuqhathaniswa nezinqamuleli ezijwayelekile, kunciphisa izindleko zokushintshwa njalo futhi kunciphisa isikhathi sokuphumula esingahlelelwe. Okwesithathu, ukuzinza kwabo okuhle kakhulu kokushaqeka kwe-thermal kuqinisekisa ukungaguquguquki phakathi nezigaba zokusebenza ezibalulekile. Lapho izithando zomlilo ziqala ukuphakama noma zivaliwe, izinga lokushisa lingashintshashintsha ngamakhulu ama-degrees ngesikhathi esifushane—ingcindezi ebangela ukuba izitini eziningi ziqhekeke noma zichitheke. Izitini ze-Magnesium-chromium, nokho, zimunca lokhu kuguquguquka kalula, zigcine ungqimba luqinile nokukhiqizwa kusebenza kahle ngaphandle kokuphazamiseka.
Lezi zakhiwo ezivelele zenza izitini ze-magnesium-chromium zibe semqoka kuzo zonke izigaba ezibalulekile zokwenza insimbi, kusukela ekucutshungulweni kwempahla eluhlaza kuya ekubunjweni kokugcina. Eziguqulini nasezifuleni zikagesi ze-arc, lapho insimbi incibilika futhi icwengisiswa khona, izitini zigxumeka izindonga zangaphakathi, zibekezelela ukukhuhlwa okuqondile kusuka ekushiseni insimbi encibilikisiwe kanye ne-slag egqwalayo. Lokhu kuvikela kuvumela amaziko ukuthi asebenze kahle kakhulu isikhathi eside, okuthuthukisa ukuphuma kwensimbi kwansuku zonke. Emalethini—izitsha ezinkulu ezithutha insimbi encibilikisiwe zisuka ezithandweni ziye emishinini yokuphonsa—izitini ze-magnesium-chromium zisebenza njengolayini oqinile. Zivimbela ukulahlekelwa ukushisa okungafaka engcupheni ikhwalithi yensimbi futhi kuvimbele ukuvuza okungaba khona, iqinisekise ukuthi insimbi encibilikisiwe ifinyelela esigabeni sayo esilandelayo esimweni esifanele sokucutshungulwa phansi komfula njengokugingqika noma ukufoja. Ngisho nasezithandweni eziqhumayo, inhliziyo yokukhiqizwa kwensimbi, lezi zitini zivikela izindawo ezibucayi ezingenhla neziphansi ekuhlaselweni okuhlangene kwegesi eshisa kakhulu (efika ku-2,000°C) kanye ne-slag encibilikisiwe, egcina ukusebenza kwesikhathi eside, okuzinzile okubalulekile ukuze kutholakale insimbi engashintshi.
Kubakhiqizi bensimbi abalwela ukukhulisa ukukhiqiza, ukunciphisa izindleko zokusebenza, nokugcina umkhawulo wokuncintisana, ukukhetha izitini zekhwalithi ephezulu ze-magnesium-chromium akuyona nje inketho—kuyisidingo. Izitini zethu ze-magnesium-chromium zakhiwe ngezilawuli zekhwalithi eziqinile, zisebenzisa izinto zokusetshenziswa ze-premium ezivivinywa kanzima ukuze zihlangabezane namazinga omkhakha womhlaba. Ithenjwa izimboni zensimbi ezihamba phambili kulo lonke elase-Asia, i-Europe, neNyakatho Melika, imikhiqizo yethu inomlando oqinisekisiwe wokuletha ukusebenza okungaguquki, ngisho nasezimweni zokukhiqiza ezidingeka kakhulu. Uzakwethu namuhla, futhi uvumele isisombululo sethu sokumelana nomlilo esihamba phambili embonini siqinise inqubo yakho yokwenza insimbi, sinciphise isikhathi sokuphumula, futhi sikusize uzuze ukukhula okuzinzile, kwesikhathi eside.
