Esimeni sokusebenza kwezimboni ezisezingeni eliphezulu, isidingo sezinto ezihlala isikhathi eside, ezimelana nokushisa asinakuxoxiswana. Kusukela ezithandweni zokwenza insimbi kuye kokasimende, okokusebenza okuchayeke emazingeni okushisa aphakeme, ukuguguleka kwamakhemikhali, nokugqokwa kwemishini kudinga ukuvikelwa okuthembekile ukuze kuqinisekiswe ukusebenza kahle nokuphila isikhathi eside. Lapha kulaphocorundum castableigqama njengento eshintsha umdlalo, enikeza ukusebenza okungenakuqhathaniswa okuhlangabezana nezindinganiso eziqinile zezimboni.
I-Corundum castable into ephikisayo ehlanganiswe ngokuyinhloko i-corundum (i-aluminium oxide, i-Al₂O₃) njenge-aggregate ne-matrix, ehlanganiswe nezibophezelo nezithasiselo zekhwalithi ephezulu. Izakhiwo zayo ezingavamile zisuka ezicini ezingokwemvelo ze-corundum, enendawo yokuncibilika engaphezu kuka-2000°C, ukuzinza okuhle kakhulu kokushisa, namandla aphakeme emishini. Ngokungafani nezinto zendabuko eziphikisayo, i-corundum castable inikeza inhlanganisela eyingqayizivele yokuguquguquka nokuqina-imvelo yayo ethelekayo ivumela ukufakwa kalula kumajamo nezakhiwo eziyinkimbinkimbi, kuyilapho isakhiwo sayo esiminyene simelana nokuhlaselwa, ukuhuzuka, nokuhlaselwa kwamakhemikhali kusuka ku-slags, ama-acids, nama-alkali.
Enye yezinzuzo ezibalulekile ze-corundum castable ukusebenzisana kwayo ngezindlela eziningi kuzo zonke izimboni. Embonini yensimbi, isetshenziswa kakhulu kumaladi, ama-tundishes, kanye nama-blast furnace linings, lapho imelana nezinga lokushisa lensimbi encibilikisiwe kanye nokusabela okunolaka kwe-slag. Abakhiqizi bensimbi bathembele ku-corundum castable ukunciphisa isikhathi sokuphumula esibangelwa ukwehluleka kwezinto ezibonakalayo, njengoba impilo yayo ende yesevisi ihumusha emijikelezweni yokunakekela embalwa kanye nezindleko zokusebenza eziphansi. Embonini kasimende, i-corundum castable isetshenziswa ezindaweni ezishintshayo zikasimende kanye nemigudu yomoya ephakeme, ebekezelela amazinga okushisa aphezulu kanye ne-clinker kasimende abrasive. Ukumelana kwayo nokushaqeka okushisayo kuqinisekisa ukuthi impahla ihlala ingashintshile ngisho nalapho izinga lokushisa lishintshashintsha, inselele evamile ekukhiqizweni kukasimende.
Ngale kwensimbi nosimende, i-corundum castable idlula zonke ku-metallurgy engeyona i-ferrous, ukukhiqizwa kwezingilazi, nezitshalo zokushiswa kwemfucuza. Ekuncibilikisweni okungeyona insimbi (isb., ithusi, i-aluminium), imelana nokugqwala okuvela ezinsimbi ezincibilikisiwe nokuguquguquka, ivikela izinto ezisetshenziswayo ezibalulekile njengeziko lokuncibilikisa nezinsimbi. Izimboni zengilazi zisebenzisa i-corundum ekwazi ukuphonswa kuma-regenerator nezimbobo zesithando somlilo, lapho igcina khona ubuqotho besakhiwo ngaphansi kokushisa okuphezulu okuqhubekayo kanye nokuchayeka kwamakhemikhali kusukela ekuncibilikeni kwengilazi. Izitshalo zokushiswa kwemfucuza ziyazuza ekumelaneni kwayo namagesi anobuthi nokuhuzuka komlotha, okunweba ubude besikhathi sokuphila kwezindwangu zokushisisa nokunciphisa izingozi zemvelo.
Esinye isici esiphoqayo se-corundum castable ukusebenza kwayo ngokwezifiso. Abakhiqizi bangakwazi ukulungisa ukwakheka kwe-corundum (isb, i-corundum emhlophe, i-brown corundum, i-tabular corundum) kanye nezithasiselo ukuze kuhambisane nezidingo ezithile zohlelo lokusebenza. Isibonelo, i-alumina corundum castable (okuqukethwe kwe-Al₂O₃ ≥ 90%) kunikeza ukumelana nokushisa okuthuthukisiwe ezindaweni ezishisa kakhulu, kuyilapho ukwakheka kukasimende ophansi noma okunosimende ophansi kakhulu kuthuthukisa ukuminyana futhi kunciphise i-porosity, kunciphise ukungena kwe-slag. Ukwengeza, izinketho ze-corundum castable lightweight zihlinzeka ngokufakwa kwe-thermal ngaphandle kokuyekethisa amandla emishini, ilungele imiklamo yezimboni ezonga amandla.
Lapho ukhetha i-corundum castable, kubalulekile ukusebenzisana nomphakeli ohlonishwayo othobela izindinganiso zekhwalithi zamazwe ngamazwe (isb., ISO, ASTM). Ikhwalithi ephezulu ye-corundum castable ibhekana nokulawulwa kwekhwalithi okuqinile, iqinisekisa ukusebenza okungaguquki, ukwakheka kwamakhemikhali okuzinzile, nezakhiwo ezithembekile zokufaka. Abahlinzeki abanolwazi lobuchwepheshe bangaphinde banikeze ukwesekwa esizeni, okuhlanganisa isiqondiso sokukhetha impahla, imiyalelo yokuxuba, namathiphu okulungisa ngemva kokufaka, okukhulisa inani lemali oyitshalile.
Esimeni sanamuhla sezimboni esincintisanayo, ukunciphisa isikhathi sokuphumula, ukwehlisa izindleko zokulungisa, kanye nokwenza ngcono ukusebenza kahle yizinto eziza kuqala. I-Corundum castable iletha kuzo zonke izinhlangothi, inikezela ngesixazululo esingabizi, esihlala isikhathi eside sezicelo ezisezingeni eliphezulu. Ukumelana nokushisa kwayo okukhethekile, ukumelana nokugqwala, kanye nokwenza izinto ezihlukahlukene kuyenza ibe into ekhethwayo ezimbonini ezifuna ukuthuthukisa ukukhiqiza nokuthembeka.
Kungakhathaliseki ukuthi usebenzisa isigayo sensimbi, isitshalo sikasimende, imboni yengilazi, noma indawo yokushiswa kwemfucuza, i-corundum castable ingaguqula ukusebenza kwakho okunezinga lokushisa eliphezulu. Tshala imali kukhwalithi ye-corundum ekwazi ukuphonswa namuhla futhi uzwe umehluko ekusebenzeni kwemishini, ukuphila isikhathi eside, kanye nemiphumela esemqoka. Xhumana nethimba lethu lochwepheshe be-refractory ukuze ufunde kabanzi mayelana nezisombululo zethu ezenziwe ngezifiso ze-corundum futhi uthathe isinyathelo sokuqala sokuthuthukisa izinqubo zakho zezimboni.
