Ezimbonini lapho ukushisa okukhulu kuyinselele eqhubekayo, ukukhetha izinto ezivimbelayo kungenza noma kuphazamise ukusebenza kahle, ukuphepha, kanye nokusebenza kahle kwezindleko. Udaka oluqinile lwe-alumina oluphezulu Ivelele njengento eyisisekelo, eyenzelwe ukumelana namazinga okushisa aphezulu angapheli, ukuguguleka kwamakhemikhali, kanye nokuguguleka kwemishini. Kungakhathaliseki ukuthi usebenza ezinsimbini, ezintweni zobumba, ekukhiqizeni ingilazi, noma kunoma yimuphi umkhakha odinga ukubopha okumelana nokushisa, lolu daka olukhethekile lunikeza ukusebenza okungenakuqhathaniswa okungafani nezinye izindlela ezijwayelekile. Ake sihlole ukuthi kungani udaka olune-alumina refractory oluphezulu luyisinqumo esiphezulu sezinhlelo zokusebenza ezibaluleke kakhulu ezishisa kakhulu emhlabeni jikelele.
Okokuqala nokubaluleke kakhulu, udaka olune-alumina refractory oluphezulu luhamba phambili ekusetshenzisweni kwensimbi, umkhakha lapho amazinga okushisa evame ukuphakama ngaphezu kuka-1500°C. Ezindaweni zokugaya insimbi, lusetshenziswa kabanzi ekuhlanganiseni izitini ezinamathelayo ezitsheni zomlilo, ama-ladle, ama-tundishes, kanye nezitofu zikagesi ze-arc. Okuqukethwe okuphezulu kwe-alumina (ngokuvamile okungu-70% kuya ku-90%) kuyinika i-refractoribility eyingqayizivele, okuvimbela ukuncibilika noma ukuguquka ngisho nangaphansi kokushisa okukhulu kwensimbi encibilikisiwe. Ngaphezu kwalokho, imelana nokugqwala okuvela ku-slag encibilikisiwe, ama-metal oxides, nezinye izinto ezinolaka ezivame ukukhiqizwa kwensimbi. Lokhu kuqina kunciphisa isikhathi sokungasebenzi esibangelwa ukwehluleka kwe-refractori, ukuqinisekisa ukusebenza okuqhubekayo nokunciphisa izindleko zokulungisa abakhiqizi bensimbi.
Izimboni ze-ceramics kanye nengilazi nazo zithembele kakhulu ku-alumina refractory mortar ephezulu. Ama-ceramics, asetshenziselwa ukubasa izitsha zobumba, amathayili, kanye ne-ceramics ethuthukisiwe, asebenza emazingeni okushisa aphakathi kuka-1200°C no-1800°C. I-alumina mortar ephezulu inikeza isibopho esiqinile nesizinzile sokushisa kwama-linings a-refractory kula ma-kiln, igcina ubuqotho besakhiwo ngisho nangesikhathi sokushisa nokupholisa okuphindaphindiwe. Kuma-glass melting furnaces, lapho amazinga okushisa edlula khona u-1600°C, ukumelana kwe-mortar ekushaqekeni kokushisa kubalulekile. Ivimbela imifantu kanye nokuqhekeka okubangelwa ukushintshashintsha kwezinga lokushisa okusheshayo, yandisa isikhathi sokuphila kwama-linings esithando futhi iqinisekise ikhwalithi yengilazi ehambisanayo. Ngokungafani nama-alumina mortars aphansi, ayisabelani nokuncibilika kwengilazi, igwema ukungcola okungonakalisa amaqoqo emikhiqizo yengilazi.
Esinye isici esibalulekile sisezitshalweni zamandla kagesi ezisebenzisa uphethiloli kanye nokushisa. Kuma-boiler, kuma-incinerator, kanye nama-reformer, i-alumina ephezulu e-refractory mortar ibopha izingxenye ezivimbela ukushisa ezibhekene namazinga okushisa aphezulu, amagesi omoya, kanye nokuhlaselwa ngamakhemikhali okuvela kumafutha kanye nemikhiqizo ephumayo. Ezitshalweni zamandla ezisebenzisa amalahle, imelana nesimo sokukhuhla somlotha wempukane kanye nemiphumela ebhubhisayo yama-sulfur oxides. Kuma-crackers e-petrochemical kanye nama-reformer, imelana nokuwohloka okuvela kuma-hydrocarbon kanye nomusi oshisa kakhulu, iqinisekisa ukukhiqizwa kwamandla okuphephile nokusebenza kahle. Izakhiwo zayo ezinhle zokunamathela nazo ziyenza ibe yindawo ekahle yokulungisa ama-linings avimbela ukushisa, inciphise isikhathi sokungasebenzi futhi yandise impilo yenkonzo yemishini ebalulekile.
Ngaphandle kwalezi zimboni eziyinhloko, udaka olune-alumina refractory oluphezulu lusetshenziswa ezitshalweni zokushisa imfucuza, lapho luphatha khona amazinga okushisa aphezulu kanye namagesi agqwalisayo akhiqizwa ukushisa imfucuza kamasipala neyezimboni. Lubalulekile futhi ezindaweni zokwenziwa kwezinsimbi zokubopha kanye nezinto ezisetshenziswa ekubunjweni kwezinsimbi. Ukuguquguquka kwalo, kuhlanganiswe nokumelana kwalo nokushisa okuphezulu kanye nokuqina kwalo, kwenza kube yisisombululo esijwayelekile sanoma yiluphi uhlelo lokusebenza oludinga ukubopha okuthembekile ezindaweni ezishisayo kakhulu.
Uma ukhetha udaka olune-alumina refractory olune-alumina ephezulu, kubalulekile ukukhetha umkhiqizo osezingeni eliphezulu ohlangabezana nezindinganiso zomkhakha. Funa udaka olune-particle size distribution efanayo, ukunamathela okuqinile, kanye nokumelana okuhle kakhulu nokushisa. Udaka lwethu olune-alumina refractory olune-alumina ephezulu lukhiqizwa kusetshenziswa izinto zokusetshenziswa zekhwalithi ephezulu kanye namasu okucubungula athuthukile, okuqinisekisa ukuthi lunikeza ukusebenza okuhle kakhulu ezinhlelweni ezidinga kakhulu. Kungakhathaliseki ukuthi udinga ukufaka uthango olukhulu lwensimbi, ukulungisa i-ceramic kiln, noma ukugcina i-power plant boiler, udaka lwethu lunikeza ukuthembeka kanye nobude besikhathi obudingayo ukuze ugcine imisebenzi yakho isebenza kahle.
Ungayekethisi ekusebenzeni kahle uma kukhulunywa ngezicelo ezishisa kakhulu. Khetha i-alumina refractory mortar ephezulu ukuze uvikele ukushisa okuphezulu, ukumelana nokugqwala, kanye nokuqina. Xhumana nathi namuhla ukuze ufunde kabanzi ngemikhiqizo yethu nokuthi ingathuthukisa kanjani ukusebenza kwakho kahle futhi inciphise izindleko zokulungisa.
