Gutera kwa Mullite bikozwe muburyo bwiza bwo hejuru bwa mullite agregate, ukongeramo ifu nziza ninyongeramusaruro zo gukurura ibintu.Ingano yingirakamaro ya mullite igiteranyo ni 12mm;Ikoreshwa ryigihe kirekire ni 1350 ℃.Kubaka mullite imbaraga-nyinshi zo kwambara-zidashobora kwangirika zirakomeye.Amashanyarazi ashobora kuvangwa n'amazi meza.Impapuro zasutswe namazi zigomba kugira imbaraga nimbaraga zihagije.Ingano yububiko igomba kuba yuzuye.Guhindura ibintu bigomba gukumirwa mugihe cyo kubaka.Ihuriro ryimikorere igomba kuba ikomeye.
Mubisabwa byubwubatsi bwa mullite retractory castable, hafatwa ingamba zo kurwanya gufatira ibyemezo, kandi ubuso bwububiko bwubushyuhe bwumuriro buhuza abaterankunga buzaba butarimo amazi.Abaterankunga bagomba kuvangwa nuruvange rukomeye.Igihe cyo kuvanga nubunini bwamazi bigomba gukurikiza amabwiriza yubwubatsi.Imvange, hopper hamwe nuburemere bipima bigomba guhanagurwa mugihe uhinduye umubare wa tray.Kuvanga ibyuma byahujwe bizarangira bitarenze 30min cyangwa ukurikije amabwiriza yo kubaka.Ibikoresho bishya byakozwe ntibishobora gukoreshwa.Kwiyongera kwinshi kwingingo zogusubiramo bigomba gushyirwaho ukurikije ibisabwa.
Nta mbaraga zo hanze cyangwa kunyeganyega bizakoreshwa mugihe cyo gukira.Fungura ifumbire.Nta fomu igomba gupakirwa, kandi imbaraga zibikoresho byo guteramo bigomba kuba kuburyo hejuru nu mfuruka zububiko bwangiritse bitangiritse cyangwa ngo bihindurwe kandi bishobora kuvaho.Nyuma yo guta ibikoresho bigeze kuri 70% byimbaraga zo gushushanya, impapuro zo gutwara zizakurwaho.Amashanyarazi ashyushye kandi akomeye agomba gutekwa kubushyuhe bwagenwe mbere yo kuzinga.Ubuso busukuye bugomba kuba butarimo gukuramo, gucamo, imyenge, nibindi.Ibikoresho byabugenewe byateguwe ntibishobora gushyirwa kumugaragaro.Hagomba gufatwa ingamba zo kwirinda imvura hamwe nubushuhe bwamazi.
Mullite castable ifite ubushyuhe bwinshi kandi irashobora guhita ihura nimirimo ikora, ikamenya ko izigama ingufu zubushyuhe bwo hejuru, uburemere bwumucyo hamwe no kugabanuka kwa 40 ~ 60% muburemere bwimiterere Ubushyuhe buke bwumuriro, igiteranyo cya mullite igiteranyo, ubushyuhe buke bwumuriro, imikorere myiza yubushyuhe bwumuriro , gukama vuba, kugabanya igihe cyo kumisha, inyungu zubukungu.
Ubwoko bwa binder bukozwe muri mullite ishobora kugumana imikorere myiza ya mullite.Guhambira ni byiza guhuza, bishobora gukora mullite ku bushyuhe runaka.Urebye ikoreshwa rya castable mubihe bitandukanye, mullite igomba gukorwa mubushyuhe buke bushoboka.Ikigaragara ni uko silika gel ifata neza.Urebye igiciro gito, silika gel ikoreshwa muguhuza kwihuza na colloidal ihagarikwa, aho Al2O3: SiO2 igomba kuba hafi cyangwa ingana na mullite.
Aluminium ifite hydratiya nziza nuburyo bukomeye bwo gukomera.Igikorwa cyo hejuru ni kinini cyane, uruhare rwacyo rero muri retable retable ni ugukorana na SiO2ifu yo gukora mullite ku bushyuhe buke, bityo umubare wongeyeho Al2O3+ SiO2ni byiza guhuza.Ibisubizo byerekana ko binders zombi zishobora gukora mullite kandi zikagira imbaraga zikonje.
