Emsebenzini wezimboni oshisa kakhulu, isidingo sezinto eziqinile, ezingamelani nokushisa asinakuxoxiswana ngaso. Kusukela ezithandweni zokwenza insimbi kuya ezitsheni zikasimende, imishini evezwe emazingeni okushisa aphezulu, ukuguguleka kwamakhemikhali, kanye nokuguguleka kwemishini kudinga ukuvikelwa okuthembekile ukuqinisekisa ukusebenza kahle kanye nokuphila isikhathi eside. Yilapho-ke laphoi-corundum castableIvelele njengento eshintsha umdlalo, inikeza ukusebenza okungenakuqhathaniswa okuhlangabezana nezindinganiso zezimboni eziqinile kakhulu.
I-Corundum castable iyinto ephikisayo eyakhiwe ngokuyinhloko yi-corundum (i-aluminium oxide, i-Al₂O₃) njenge-aggregate kanye ne-matrix, ehlanganiswe nezihlanganisi zekhwalithi ephezulu kanye nezithasiselo. Izakhiwo zayo eziyingqayizivele zivela ezicini ezingokwemvelo ze-corundum, enezinga lokuncibilika elingaphezu kuka-2000°C, ukuqina kokushisa okuhle kakhulu, kanye namandla aphezulu omshini. Ngokungafani nezinto zendabuko eziphikisayo, i-corundum castable inikeza inhlanganisela eyingqayizivele yokuguquguquka nokuqina—imvelo yayo yokuthulula ivumela ukufakwa okulula ezimweni nasezitakhiweni eziyinkimbinkimbi, kuyilapho isakhiwo sayo esiqinile simelana nokuqhekeka, ukuguguleka, kanye nokuhlaselwa ngamakhemikhali okuvela kuma-slags, ama-acid, nama-alkali.
Enye yezinzuzo ezibalulekile ze-corundum castable ukuguquguquka kwayo kuzo zonke izimboni. Embonini yensimbi, isetshenziswa kabanzi ezindishini, kuma-tundishes, nasezindaweni zomlilo, lapho imelana khona namazinga okushisa ensimbi encibilikisiwe kanye nokusabela okunamandla kwe-slag. Abakhiqizi bensimbi bathembele ku-corundum castable ukuze banciphise isikhathi sokungasebenzi esibangelwa ukwehluleka kwezinto, njengoba impilo yayo ende yenkonzo isho ukuthi imijikelezo yokulungisa imbalwa kanye nezindleko zokusebenza eziphansi. Embonini yensimbi, i-corundum castable isetshenziswa ezindaweni zokushintsha ze-cement kiln kanye ne-tertiary air ducts, ebekezelela amazinga okushisa aphezulu kanye ne-abrasive cement clinker. Ukumelana kwayo nokushaqeka kokushisa kuqinisekisa ukuthi izinto zihlala ziqinile ngisho nangesikhathi sokushintshashintsha kwezinga lokushisa okusheshayo, inselele evamile ekukhiqizweni kwensimbi.
Ngaphandle kwensimbi kanye nesamente, i-corundum castable ihamba phambili ekusetshenzisweni kwensimbi okungeyona i-ferrous, ekukhiqizweni kwengilazi, kanye nasezitshalweni zokushisa imfucuza. Ekuncibilikiseni okungeyona i-ferrous (isb., ithusi, i-aluminium), imelana nokugqwala okuvela ezinsimbini ezincibilikisiwe kanye nokugeleza, ivikela imishini ebalulekile njengezitofu zokuncibilikisa kanye nezinto zokusha. Izimboni zengilazi zisebenzisa i-corundum castable kuma-regenerator kanye nasezimbobeni ze-furnace, lapho igcina khona ubuqotho besakhiwo ngaphansi kokushisa okuphezulu okuqhubekayo kanye nokuvezwa kwamakhemikhali okuvela ekuncibilikeni kwengilazi. Izitshalo zokushisa imfucuza ziyazuza ekumelaneni kwayo namagesi anobuthi kanye nokuguguleka komlotha, zandisa isikhathi sokuphila kwezingxenye zokushisa kanye nokunciphisa izingozi zemvelo.
Esinye isici esithakazelisayo se-corundum castable ukusebenza kwayo ngokwezifiso. Abakhiqizi bangalungisa ukwakheka kwe-corundum (isb., i-corundum emhlophe, i-corundum ensundu, i-corundum yethebula) kanye nezithasiselo ukuze zivumelane nezidingo ezithile zohlelo lokusebenza. Isibonelo, i-corundum castable ene-alumina ephezulu (okuqukethwe kwe-Al₂O₃ ≥ 90%) inikeza ukumelana nokushisa okuthuthukisiwe ezindaweni ezishisa kakhulu, kuyilapho ukwakheka kwe-cement ephansi noma i-cement ephansi kakhulu kuthuthukisa ubuningi futhi kunciphisa ukugoba, kunciphisa ukungena kwe-slag. Ngaphezu kwalokho, izinketho ze-corundum castable ezilula zinikeza ukuvikelwa kokushisa ngaphandle kokubeka engcupheni amandla emishini, okulungele imiklamo yezimboni eyonga amandla.
Uma ukhetha i-corundum castable, kubalulekile ukusebenzisana nomhlinzeki othembekile onamathela ezindinganisweni zekhwalithi zomhlaba wonke (isb., i-ISO, i-ASTM). I-corundum castable esezingeni eliphezulu ilawulwa ngokuqinile kwekhwalithi, iqinisekisa ukusebenza okulinganayo, ukwakheka kwamakhemikhali okuzinzile, kanye nezakhiwo zokufaka ezithembekile. Abahlinzeki abanolwazi lobuchwepheshe banganikeza nokusekelwa endaweni, okuhlanganisa isiqondiso sokukhetha izinto, imiyalelo yokuxuba, kanye namathiphu okulungisa ngemva kokufakwa, okwandisa inani lokutshalwa kwezimali kwakho.
Esimweni sezimboni esincintisanayo sanamuhla, ukunciphisa isikhathi sokungasebenzi, ukunciphisa izindleko zokulungisa, kanye nokuthuthukisa ukusebenza kahle kuyizinto eziza kuqala. I-Corundum castable ihlinzeka ngazo zonke izinhlangothi, inikeza ikhambi elingabizi kakhulu nelihlala isikhathi eside lezinhlelo zokusebenza ezishisa kakhulu. Ukumelana kwayo nokushisa okumangalisayo, ukumelana nokugqwala, kanye nokuguquguquka kwenza kube yinto ekhethwayo yezimboni ezifuna ukuthuthukisa umkhiqizo kanye nokuthembeka.
Kungakhathaliseki ukuthi usebenzisa umshini wokugaya insimbi, isitshalo sikasimende, ifektri yengilazi, noma isikhungo sokushisa imfucuza, i-corundum castable ingashintsha imisebenzi yakho yokushisa okuphezulu. Tshala imali ku-corundum castable esezingeni eliphezulu namuhla futhi uzwe umehluko ekusebenzeni kwemishini, isikhathi eside, kanye nemiphumela ephansi. Xhumana nethimba lethu lochwepheshe abaphikisayo ukuze ufunde kabanzi mayelana nezixazululo zethu ze-corundum castable ezenziwe ngokwezifiso bese uthatha isinyathelo sokuqala sokwenza ngcono izinqubo zakho zezimboni.
