Mu rwego rw’ibikorwa byo mu rwego rwo hejuru by’inganda, gukenera ibikoresho biramba, birwanya ubushyuhe ntibishobora kuganirwaho. Kuva mu itanura ryo gukora ibyuma kugeza ku ziko rya sima, ibikoresho byugarijwe n'ubushyuhe bukabije, isuri y’imiti, hamwe n’imyenda ya mashini bisaba uburinzi bwizewe kugira ngo bikore neza kandi birambe. Aha nihocorundum castableigaragara nkibikoresho bihindura umukino, bitanga imikorere ntagereranywa yujuje ubuziranenge bwinganda.
Corundum castable ni ibintu byangiritse bigizwe ahanini na corundum (oxyde ya aluminium, Al₂O₃) nka agregate na matrix, ihujwe na binders nziza kandi nziza. Imiterere yihariye ikomoka kubiranga corundum, ifite aho ishonga irenga 2000 ° C, ihindagurika ryiza ryumuriro, nimbaraga zikomeye za mashini. Bitandukanye nibikoresho gakondo byangiritse, corundum castable itanga uruvange rwihariye rwo guhinduka no kuramba - imiterere yacyo isukwa ituma hashobora gushyirwaho byoroshye muburyo bugoye kandi byubatswe, mugihe imiterere yacyo yuzuye irwanya gusenyuka, gukuramo, hamwe nigitero cyimiti ituruka kumasaka, acide, na alkalis.
Imwe mu nyungu zingenzi za corundum castable nuburyo bwinshi butandukanye mu nganda. Mu nganda zibyuma, ikoreshwa cyane mubitereko, tundishing, hamwe no gutanura itanura, aho bihanganira ubushyuhe bwicyuma gishongeshejwe hamwe nigitero gikaze. Abakora ibyuma bishingikiriza kuri corundum castable kugirango bagabanye igihe cyatewe no kunanirwa kwibintu, kuko ubuzima bwigihe kirekire bwo gukora busobanura uburyo buke bwo kubungabunga no kugiciro cyibikorwa. Ku nganda za sima, corundum castable ikoreshwa mukarere ka sima ya sima hamwe nuyoboro wo mu kirere cya gatatu, bihanganira ubushyuhe bwinshi hamwe na climer ya sima. Kurwanya ihungabana ry’ubushyuhe byemeza ko ibikoresho bikomeza kuba byiza ndetse no mu gihe cy’imihindagurikire y’ubushyuhe bwihuse, ikibazo gikunze kugaragara mu musaruro wa sima.
Kurenga ibyuma na sima, corundum ishobora kuba nziza muri metallurgie idafite ferrous, gukora ibirahure, hamwe n’inganda zitwika imyanda. Mu gushonga bidafite ferrous (urugero, umuringa, aluminium), irwanya kwangirika kwicyuma gishongeshejwe, ikarinda ibikoresho bikomeye nko gushonga itanura hamwe n umusaraba. Uruganda rw'ibirahuri rukoresha corundum rushobora gukoreshwa mu byuma bisubiramo ibyuma ndetse no ku byambu, aho bigumana ubusugire bw'imiterere mu gihe cy'ubushyuhe bukabije ndetse n'imiti ikomoka ku kirahure. Ibihingwa bitwika imyanda byungukirwa no kurwanya imyuka y’ubumara no gukuramo ivu, byongerera igihe cyo gutwika no kugabanya ingaruka z’ibidukikije.
Ikindi kintu gikomeye kiranga corundum castable nigikorwa cyacyo cyihariye. Ababikora barashobora guhindura ibice bya corundum (urugero: corundum yera, corundum yumukara, tabular corundum) hamwe ninyongera kugirango bahuze ibikoresho nibisabwa bikenewe. Kurugero, high-alumina corundum castable (Ibirimo Al₂O₃ ≥ 90%) itanga ubushyuhe bwiyongera kubushyuhe bukabije bwibidukikije, mugihe sima nkeya cyangwa ultra-hasi-sima byongera ubwinshi kandi bikagabanya ubukana, bikagabanya kwinjira. Byongeye kandi, korundum yoroheje yamashanyarazi itanga ubushyuhe bwumuriro utabangamiye imbaraga za mashini, nibyiza mubikorwa byinganda bizigama ingufu.
Mugihe uhisemo corundum castable, nibyingenzi gufatanya nuwitanga isoko wubahiriza amahame yubuziranenge mpuzamahanga (urugero, ISO, ASTM). Ubwiza bwa corundum castable bugenzurwa neza, bugakora imikorere ihamye, imiti ihamye, hamwe nuburyo bwizewe bwo kwishyiriraho. Abatanga ubumenyi bwa tekinike barashobora kandi gutanga infashanyo kurubuga, harimo kuyobora ibikoresho byo guhitamo ibikoresho, kuvanga amabwiriza, hamwe ninama zokubungabunga nyuma yo kwishyiriraho, kugabanya agaciro kishoramari ryawe.
Muri iki gihe imiterere y’inganda irushanwa, kugabanya igihe, kugabanya ibiciro byo kubungabunga, no kunoza imikorere ni byo biza imbere. Corundum castable itanga kumpande zose, itanga ikiguzi-cyiza, kirambye kirambye kubushyuhe bwo hejuru. Kurwanya ubushyuhe budasanzwe, kurwanya ruswa, no guhuza byinshi bituma iba ibikoresho byo guhitamo inganda zishaka kuzamura umusaruro no kwizerwa.
Waba ukora uruganda rukora ibyuma, uruganda rwa sima, uruganda rw ibirahure, cyangwa ikigo cyo gutwika imyanda, corundum castable irashobora guhindura ibikorwa byubushyuhe bwo hejuru. Shora muri corundum yujuje ubuziranenge uyumunsi kandi wibonere itandukaniro ryimikorere yibikoresho, kuramba, nibisubizo byo hasi. Menyesha itsinda ryacu ryinzobere mu kwanga kugirango umenye byinshi kubyerekeye ibisubizo byihariye bya corundum castable ibisubizo hanyuma ufate intambwe yambere yo kunoza imikorere yinganda.
