Emisebenzini yezimboni eshisa kakhulu, ukusebenza kwezinto eziphikisayo kunquma ngqo ukusebenza kahle kokukhiqiza, ukuphepha, kanye nokulawula izindleko.I-Castable Ephansi Yesimende (LCC)isivele njengesixazululo esishintsha umdlalo, esihlukaniswa ngokuqukethwe kwayo okuphansi kwe-calcium oxide (≤3%) kanye nokwengezwa okuncane kwesimende (3%-8%), okunikeza izakhiwo eziqinile zokungaguquki uma kuqhathaniswa nezinto ezisetshenziswayo zendabuko. Ukumelana kwayo nokushaqeka kokushisa okumangalisayo, ukumelana nokuguguleka kwe-slag, kanye namandla okushisa aphezulu kuyenza ibe yinto ebaluleke kakhulu ezimbonini eziningi emhlabeni jikelele.
Imboni yensimbi iyona ezuza kakhulu nge-castable kasimende ephansi, lapho iphumelela khona ezindaweni ezishisayo nezinzima. Isetshenziswa kabanzi ezindongeni zezitofu zokwelapha ukushisa, izitofu zokushisa, nama-rotary kilns, kanye nezimbozo ze-furnace kagesi kanye nama-tapholes e-blast furnace. Ekukhiqizweni kwensimbi, i-LCC inikeza isivikelo esithembekile sezitsha, ama-tundishes, kanye nezindawo zokushisa izitsha, imelana nokugqwala okuvela ku-slag yensimbi encibilikisiwe kanye nensimbi ngenkathi igcina ubuqotho besakhiwo emazingeni okushisa afinyelela ku-1800℃. Ezindaweni zokushisa ezingezona ezensimbi, ilungele izitofu zokubamba i-aluminium, izindawo zokugeza ezidluliswayo, kanye nezindawo zokushisa ze-electrolytic cell, ngenxa yezithasiselo ezinciphisa ukungena kwensimbi encibilikisiwe.
Imboni yesamente ithembele kakhulu ekuphonsweni kwesimende okuphansi ukuze kuthuthukiswe ukuqina kwemishini ebalulekile yokushisa. Ivame ukusetshenziswa ku-kilneye yangemuva, isembozo se-wicket, kanye nengemuva elipholile lama-kilneye ajikelezayo esimende, lapho imelana khona namazinga okushisa aphezulu nezinto ezihudulayo, yandisa impilo yesevisi yemishini kakhulu. Ukushuba kwayo okuphansi kanye nokuxinana okuphezulu kuvimbela ukulahleka kokushisa, kuthuthukisa ukusebenza kahle kwamandla kanye nokunciphisa isikhathi sokungasebenzi kokulungisa—izici ezibalulekile kubakhiqizi besimende abafuna ukunciphisa izindleko.
Ngaphandle kwe-metallurgy kanye ne-samente, i-low cement castable isebenza izindima ezahlukahlukene embonini ye-petrochemical, ugesi, kanye nokwelashwa kwemfucuza. Ezitshalweni ze-petrochemical, ifaka ama-catalytic cracking reactors kanye namapayipi okushisa okuphezulu, imelana nokuguguleka kwamakhemikhali kanye nokujikeleza kokushisa. Ukuze kukhiqizwe ugesi, isetshenziswa emakamelweni okushisa amabhoyila, ama-flue, kanye nama-cyclone separator, ivikela emazingeni okushisa aphezulu kanye nokugqwala kwegesi ye-flue. Isebenza kahle futhi kuma-incinerator emfucuza, lapho imelana khona nokugqwala okuvela kumagesi e-flue ayinkimbinkimbi, anobuthi kanye nezinhlayiya zomlotha ezirhabaxa.
Ukuguquguquka kwe-castable esimende esincane kuthuthukiswa kakhulu yizinketho zayo zokwakha eziguquguqukayo. Itholakala njengezinhlobo ezidlidlizayo noma ezizigelezela zona, ingaphonswa, igcotshwe, noma ipompelwe endaweni, ivumelane nezimo eziyinkimbinkimbi nezindawo okunzima ukufinyelela kuzo ngaphandle kokuphazamisa ukusebenza kwayo. Amandla ayo okushisa aphezulu ayanda ngokwelashwa kokushisa, okunqoba ubuthakathaka be-castable zendabuko ezilahlekelwa amandla ku-800-1200℃.
Kungakhathaliseki ukuthi kungama-oven abalulekile ezimbonini, ukuphathwa kwensimbi encibilikisiwe, noma amapayipi okushisa okuphezulu, i-castable yesamente ephansi inikeza ukusebenza okuhlala njalo nokuhlala isikhathi eside. Inhlanganisela yayo yokuqina, ukuguquguquka, kanye nokusebenza kahle kwamandla kwenza kube yisisombululo esithandwayo sokungaguquki kwezimboni zanamuhla ezishisa kakhulu. Khetha i-LCC ukuze unciphise izindleko zokulungisa, uthuthukise ukuphepha kokusebenza, futhi ufeze imigomo yokukhiqiza esimeme.
