Emkhakheni wezimboni onezinga eliphezulu lokushisa eliphezulu, ukusebenza kwezisetshenziswa ze-kiln lining kuthinta ngokuqondile ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo. Njengommeleli wezinto ezisebenza kahle eziphikisayo, izitini ze-magnesia-alumina spinel, nezakhiwo zazo ezinhle kakhulu eziphelele, ziye zaba yisinqumo esihle ezimbonini ezifana nensimbi, ingilazi, nosimende ukumelana nokuguguleka kwezinga lokushisa eliphezulu nokwandisa isikhathi sokuphila kwemishini, ukuhlinzeka ngokusekela okuthembekile ukukhiqizwa kwezimboni ezisezingeni eliphezulu.
Ukuhola Imboni Ngokusebenza Okuvelele
Izitini ze-Magnesia-alumina spinel zihlanganiswa kusuka ku-magnesia ne-aluminium oxide ngezinqubo ezikhethekile. Isakhiwo sabo sekristalu esiyingqayizivele sibanikeza izinzuzo ezinamandla zokusebenza. Lezi zitini zibonisa ukumelana nezinga lokushisa eliphezulu okuvelele, ezikwazi ukumelana namazinga okushisa afinyelela ku-1800°C. Ngisho nasezindaweni ezihlala isikhathi eside ezinokushisa okuphezulu, zigcina izakhiwo ezinzile ngokomzimba namakhemikhali, zivimbela ngokuphumelelayo ukulimala kwezindwangu zokushisa ezibangelwa ukushisa okuphezulu.
Ukumelana nokushisa okushisayo kuyisici esiphawulekayo sezitini ze-magnesia-alumina spinel. Ngesikhathi semijikelezo yokushisisa nokupholisa kaningi kweziko, izinto ezijwayelekile eziphikisayo zijwayele ukuqhekeka nokuqhekeka ngenxa yengcindezi yokushisa. Kodwa-ke, nge-coefficient yabo ephansi yokwanda okushisayo kanye nokuqina okuhle, izitini ze-magnesia-alumina spinel zinganciphisa ngempumelelo imithelela yokucindezeleka okushisayo, zinciphise kakhulu ingozi yokulimala kokushaqeka okushisayo, ukwandisa impilo yesevisi, nokunciphisa isikhathi somlilo somlilo ukuze sigcinwe.
Izitini ze-Magnesia-alumina spinel nazo zenza kahle kakhulu ekuvikelweni kokuguguleka kwamakhemikhali. Banokumelana okuhle kakhulu ne-alkaline kanye ne-acidic slag, kanye namagesi aphezulu okushisa, ukuvimbela ngokuphumelelayo ukungena kwezinto eziyingozi nokuvikela ukuphepha kwesakhiwo seziko. Kungakhathaliseki ukuthi kusendaweni ene-alkaline yokuncibilika kwensimbi noma endaweni ene-acidic ephezulu yezinga lokushisa yokukhiqiza ingilazi, bangakwazi ukufeza imisebenzi yabo yokuvikela ngokuzinza.
Izinhlelo zokusebenza ezijulile kuzo zonke izimboni eziningi
Embonini yensimbi, izitini ze-magnesia-alumina spinel zisetshenziswa kabanzi ezindaweni ezibalulekile zabaguquli, ama-ladles, nama-tundishes. Ngesikhathi sokwenza insimbi yokuguqula, bangakwazi ukumelana nokukhuhla nokuguguleka kwensimbi encibilikisiwe enezinga lokushisa eliphezulu kanye ne-slag, okuqinisekisa ubuqotho bomugqa wokuguqula. Uma isetshenziswa kumaladi nama-tundishes, inganciphisa ngempumelelo ukusabela phakathi kwensimbi encibilikisiwe nezinto zolwelwesi, ithuthukise ukuhlanzeka kwensimbi encibilikisiwe, futhi ithuthukise ikhwalithi yensimbi. Ngemuva kokuthi inkampani enkulu yensimbi yamukele izitini ze-magnesia-alumina spinel, impilo yesevisi ye-ladles yayo yanda isuka esilinganisweni sama-heaters angu-60 kuya ku-120 heats, ukunciphisa kakhulu izindleko zokukhiqiza.
Embonini yokukhiqiza ingilazi, izitini ze-magnesia-alumina spinel ziyizinto ezikhethwayo zezingxenye ezibalulekile zama-glass kilns. Ezindaweni ezishisayo kanye nama-regenerators eziko ezincibilikisa ingilazi, angakwazi ukumelana nokuguguleka kokuncibilika kwengilazi okunezinga lokushisa eliphezulu kanye nokugwazwa kwamagesi ashisa kakhulu, kugcinwe ukuqina kwesakhiwo seziko, kuncishiswe imvamisa yokulungisa iziko, nokwenza ngcono ukuqhubeka nokuzinza kokukhiqizwa kwengilazi. Ngemuva kokusebenzisa izitini ze-magnesia-alumina spinel, umjikelezo wokulungisa izikebhe zengilazi unganwetshwa ngeminyaka engu-2 - 3, uthuthukise ngempumelelo izinzuzo zezomnotho zamabhizinisi.
Ngesikhathi sokukhiqizwa kukasimende, izinga lokushisa eliphezulu leziko lokujikeleza libeka izidingo eziqinile ezintweni eziphikisayo. Ngokumelana kwazo nokushisa okuphezulu, ukumelana nokuhuzuka, nokuzinza okuhle kwamakhemikhali, izitini ze-magnesia-alumina spinel zidlala indima ebalulekile endaweni yoguquko kanye nendawo evuthayo yezikloni ezijikelezayo, ziqinisekisa ukusebenza okuzinzile komzimba wokushisa ngaphansi kwezimo ezishisa kakhulu nezinomthwalo omkhulu futhi zibe negalelo ekwandeni kokukhiqizwa kukasimende kanye nekhwalithi ethuthukisiwe.
Umhlahlandlela Wokuthenga Ochwepheshe
Uma ukhetha izitini ze-magnesia-alumina spinel, amaphuzu abalulekile alandelayo kufanele agcizelelwe: Okokuqala, qaphela ukwakheka kwamakhemikhali kanye nokwakheka kwamaminerali kwezinto. I-high-purity magnesia kanye ne-aluminium oxide izinto zokusetshenziswa zingaqinisekisa ukusebenza okuzinzile kwezitini. Okwesibili, gxila ezibonisini zokusebenza ngokomzimba zemikhiqizo, njengokuminyana kwenqwaba, i-porosity ebonakalayo, namandla okucindezela okubandayo ekamelweni lokushisa. Lezi zinkomba zibonisa ngokuqondile ikhwalithi nokuqina kwezitini. Okwesithathu, hlola inqubo yokukhiqiza kanye nohlelo lokulawula ikhwalithi lwabahlinzeki. Khetha abahlinzeki abanamathuluzi okukhiqiza athuthukile, izinqubo zokuhlola eziphelele, nolwazi olucebile lwemboni ukuze uqinisekise ikhwalithi yomkhiqizo ethembekile. Ukwengeza, ngokuvumelana nezimo ezithile zokusebenza, ukunemba kwe-dimensional kanye nokuguquguquka kwesimo sezitini nakho kudingeka kucatshangelwe ukuze kuqinisekiswe ukwakhiwa nokufakwa okubushelelezi.
Ngokusebenza kwazo okuvelele kanye nezicelo ezibanzi, izitini ze-magnesia-alumina spinel seziphenduke izinto eziphikisayo ezisebenza kahle kakhulu ezimbonini ezisezingeni eliphezulu. Noma ngabe ukuthuthukisa ukusebenza kahle kokukhiqiza, ukunciphisa izindleko, noma ukuqinisekisa ikhwalithi yomkhiqizo, banganikeza izixazululo ezithembekile zamabhizinisi. Xhumana nathi manje ukuze uthole ulwazi lomkhiqizo ochwepheshe kanye nezinsizakalo ezenziwe ngezifiso, futhi usivumele sivikele ukukhiqizwa kwakho kwezimboni ezisezingeni eliphezulu!
