Ipayipi lerabha le-alumina ceramic elingagugi liwumkhiqizo wepayipi lezimboni owenziwe ngokuhlanganisa amathayili e-alumina ceramic anobunzima obuphezulu ne-raber matrix eguquguqukayo ngenqubo ye-vulcanization. I-alumina ceramic ehlanganisiwe (ngokuvamile enokuqukethwe kwe-Al₂O₃ okungu-≥92%) inobunzima obuphezulu kakhulu (ubunzima be-Rockwell HRA ≥88), ekhombisa ukumelana nokuguguleka okuphindwe kayishumi kunokwensimbi ephezulu ye-chromium. Ingqimba yerabha yangaphandle inika ipayipi ukuguquguquka okuhle kakhulu kanye nezakhiwo zokuvala, okuvumela ukuthi igobe futhi imunce ukudlidliza komthelela ngaphansi kwezimo zokusebenza eziyinkimbinkimbi. Lo mklamo wesakhiwo uhlanganisa ngempumelelo ukumelana nokuguguleka kwe-ceramics nezakhiwo zokusika zerabha, okwenza ifaneleke kakhulu ekuthuthweni kwemidiya eguguleka kakhulu ezimbonini ezifana nezezimayini, ukukhiqizwa kwamandla, kanye nosimende.
Ngokuphathelene nemingcele yokusebenza, imininingwane yobuchwepheshe yalo mkhiqizo iyahlukahluka ngokuya ngezidingo zohlelo lokusebenza. Ingqimba ye-ceramic ngokuvamile inobukhulu obungu-≥3.6 g/cm³ kanye namandla okugoba adlula ama-290MPa. Ngenkathi ingamelana namazinga okushisa aphezulu afinyelela ku-1400°C, izinga lokushisa lokusebenza lesikhathi eside ngokuvamile lilawulwa phakathi kuka--30°C no-150°C ekusebenzeni okuqhubekayo ngenxa yemikhawulo yokushisa yengqimba yerabha. Imininingwane yepayipi iyaguquguquka, ngobubanzi obujwayelekile obusukela ku-25mm kuya ku-1200mm, ubude obubodwa bufika kumamitha angama-20, kanye namazinga okucindezela okusebenza aphakathi kuka-1MPa no-4MPa. Ngaphezu kwalokho, amathayili e-ceramic avame ukuklanywa ngesimo esinonxande noma esiyindilinga futhi ahlelwe kahle futhi avunguliwe ukuqinisekisa udonga lwangaphakathi olubushelelezi olunokumelana okuphansi koketshezi.
Amapayipi enjoloba e-alumina ceramic amelana nokugugulekaZisetshenziswa kabanzi ezinhlelweni zokudlulisa izinto zokugeleza kwegesi eqinile-uketshezi-isigaba esiningi. Ezitshalweni zamandla ezisebenzisa amalahle, zisetshenziselwa ukuthutha umlotha wempukane namalahle acoliwe ngomoya. Embonini yensimbi, zisetshenziselwa ukufaka amalahle acoliwe kanye nokuthutha i-iron ore concentrate. Emkhakheni wamakhemikhali, zisebenzisa ukumelana nokugqwala kwe-ceramics, lawa mapayipi angadlulisa ama-slurry aqothulayo aqukethe ama-acid, ama-alkali, kanye nosawoti. Ngaphezu kwalokho, ekusebenzeni kokumba imigodi kanye nokupompa ukhonkolo, leli payipi, ngezinzuzo zalo ezimbili zokumelana nokushayisana kanye nokumelana nokuguguleka, landisa kakhulu umjikelezo wokugcinwa kanye nokuphila kwenkonzo yesistimu yamapayipi, ngaleyo ndlela kunciphisa izindleko zokusebenza nezokugcinwa.
