Ama-oven ajikelezayo esimendeyimishini eyinhloko ekukhiqizweni kwesimende, esebenza ngaphansi kwezimo ezimbi kakhulu—amazinga okushisa afinyelela ku-1450°C, ukuguguleka okukhulu kwamakhemikhali okuvela ku-alkaline media kanye ne-clinker, kanye nokuguguleka okuqhubekayo kwemishini. Ukukhetha izitini ezimelana nokushisa okulungile kubalulekile ekuqinisekiseni ukusebenza okuzinzile, ukwandisa impilo yesevisi yesitofu, kanye nokunciphisa izindleko zokulungisa. Ngezansi kunezinhlobo ezibalulekile zezitini ezimelana nokushisa ezenzelwe izitofu ezijikelezayo zesimende, ngasinye senzelwe izindawo ezithile zokusebenza.
Izitini ze-Alumina Eziphezuluyizitini ezisetshenziswa kakhulu ezishintsha umbala ezitsheni ezijikelezayo zesimende. Njengoba zinokuqukethwe kwe-alumina okungu-48% kuya ku-75%, zinokumelana okuhle kakhulu nokushisa okuphezulu, ukuqina okuhle kokushaqeka kokushisa, kanye nokumelana okuqinile kokuguguleka. Zisetshenziswa kakhulu ezindaweni ezingashisi kakhulu njenge-inlet ye-oven, i-preheater, kanye ne-bolposition furnace, lapho amazinga okushisa asukela ku-800°C kuya ku-1200°C. Ukuqina kwazo okuphansi kuvimbela ukungena kwegesi egqwalisayo, okwenza kube kuhle ezindaweni ezinokuguguleka kwamakhemikhali okuphakathi.
Izitini ze-Magnesia-Alumina Spinelzibalulekile endaweni evuthayo yesitofu, lapho amazinga okushisa afinyelela khona ku-1350°C kuya ku-1450°C. Njengoba zakhiwe nge-magnesium oxide ne-alumina, zinokumelana okukhulu nokushaqeka kokushisa futhi zingakha ungqimba oluvikelayo lapho zisabela ku-clinker, zimelana ngempumelelo nokuguguleka kwe-clinker okuncibilikisiwe. Uma kuqhathaniswa nezitini ze-magnesia-chrome, zinokumelana okungcono kokuqhekeka, okwenza zibe ukukhetha okuhlala isikhathi eside ezindaweni ezishisa kakhulu.
Izitini ze-Magnesia-Chrome Ezihlanganisiwe NgokuqondileZiphumelela kakhulu ekumelaneni nokugqwala kwamakhemikhali. Zenziwe nge-magnesite ne-chromite esezingeni eliphezulu, ezifakwe i-calcium ku-1750-1850°C, zilungele indawo evuthayo kanye nendawo yokuguquka, lapho ukuguguleka kwe-alkaline ne-sulfate kukhulu khona. Zinikeza izinga lokushisa eliphakeme lokuthambisa umthwalo kanye namandla amahle omshini, okuqinisekisa ukuzinza kwesikhathi eside ezindaweni ezinzima.
Izitini Ezimelana Ne-Alkalizenzelwe i-tertiary air duct kanye ne-cyclone separator, lapho ukuguguleka komoya we-alkali kugqama khona. Nge-25%-30% ye-alumina kanye ne-silica engaphezu kuka-65%, zakha ungqimba lwe-glaze olune-viscosity ephezulu ukuvimba ukungena kwe-alkali, ukuvimbela ukuqhekeka kwezitini kanye nokuqhekeka.
Ukukhetha izitini ezifanele ezimelana nokushisa ngokusekelwe ezindaweni zehhavini kuthinta ngqo ukusebenza kahle kokukhiqiza kanye nezindleko. Izitini zethu ezimelana nokushisa ezisebenza kahle kakhulu zihlangabezana nezindinganiso zomkhakha, ngezixazululo ezenziwe ngokwezifiso zezinhlobo ezahlukene zehhavini. Xhumana nathi namuhla ukuze uthole imikhiqizo ethembekile yokumelana nokushisa enciphisa isikhathi sokungasebenzi futhi ithuthukise ukusebenza kahle kokukhiqiza kwakho usimende.
