Ipayipi yerabha ye-alumina ceramic engagugiyo yimveliso yepayipi yemizi-mveliso eyenziwe ngokudibanisa iithayile ze-alumina ceramic ezinobunzima obuphezulu kunye ne-matrix yerabha eguquguqukayo ngenkqubo ye-vulcanization. I-alumina ceramic efakwe ngaphakathi (ehlala inomxholo we-Al₂O₃ ongu-≥92%) inobunzima obuphezulu kakhulu (ubunzima beRockwell HRA ≥88), ebonisa ukumelana nokugugika okuphindwe kalishumi kunokwesinyithi esinobukromi obuphezulu. Umaleko werabha wangaphandle unika ipayipi ukuguquguquka okugqwesileyo kunye neempawu zokutywina, okuvumela ukuba igobe kwaye ifunxe ukungcangcazela phantsi kweemeko zokusebenza ezinzima. Olu yilo lolwakhiwo ludibanisa ngempumelelo ukumelana nokugugika kwe-ceramics kunye neempawu zokunciphisa irabha, okwenza ukuba ifaneleke kakhulu ekuthuthweni kwemidiya enokugugika okuphezulu kumashishini afana nemigodi, ukuveliswa kwamandla, kunye nesamente.
Ngokuphathelele iiparameter zokusebenza, iinkcukacha zobugcisa zale mveliso ziyahluka ngokweemfuno zesicelo. Umaleko weseramikhi uhlala unobunzima obuyi-≥3.6 g/cm³ kwaye amandla okugoba adlula i-290MPa. Nangona unokumelana namaqondo obushushu aphezulu ukuya kuthi ga kwi-1400°C, ubushushu bokusebenza bexesha elide bulawulwa phakathi kwe--30°C kunye ne-150°C ngokuqhubekayo ngenxa yemida yobushushu yomaleko werabha. Iinkcukacha zepayipi ziyaguquguquka, kunye nobubanzi obuqhelekileyo obuqala kwi-25mm ukuya kwi-1200mm, ubude obubodwa ukuya kuthi ga kwiimitha ezingama-20, kunye namanqanaba oxinzelelo lokusebenza phakathi kwe-1MPa kunye ne-4MPa. Ngaphezu koko, iithayile zeseramikhi zihlala ziyilwe ngemilo yehexagonal okanye yesangqa kwaye zicwangciswe ngokuchanekileyo kwaye zivulwe ukuze kuqinisekiswe udonga lwangaphakathi olugudileyo olunokumelana okuncinci kolwelo.
Iipayipi zerabha ze-alumina zerabha ezingagugiyoZisetyenziswa kakhulu kwiinkqubo zokuhambisa izinto zokuhamba ngegesi eqinileyo-elulwelo-ezinezigaba ezininzi. Kwizikhululo zamandla ezisebenzisa amalahle, zisetyenziselwa ukuhambisa uthuthu oluphuma emoyeni kunye namalahle acoliweyo. Kwishishini lesinyithi, zisetyenziselwa ukufaka amalahle acoliweyo kunye nokuthutha i-iron ore concentrate. Kwicandelo leekhemikhali, zisebenzisa ukumelana nokugqwala kweeseramikhi, ezi hoses zinokuhambisa i-slurry ebolayo equlethe ii-asidi, ii-alkalis, kunye neetyuwa. Ukongeza, kwimisebenzi yokufunxa izibuko kunye nokupompa ikhonkrithi, le pipeline, enezibonelelo zayo ezimbini zokuxhathisa impembelelo kunye nokuguguleka, yandisa kakhulu umjikelo wolondolozo kunye nobomi benkonzo yenkqubo yepayipi, ngaloo ndlela inciphisa iindleko zokusebenza kunye nokugcinwa.
