Ezinqubweni zezimboni ezishisa kakhulu njengokukhiqiza usimende, ukwenza insimbi, kanye nokukhiqizwa kwengilazi, izinto eziphikisayo zibalulekile ekuzinzeni kokusebenza kanye nokulawula izindleko.Izitini ze-spinel ze-Magnesia alumina, ukukhetha okuphezulu kwabasebenzisi bezimboni emhlabeni jikelele, kuvelele ngokuqina kokushisa okumangalisayo, ukumelana nokugqwala, kanye nobungane nemvelo.Lo mhlahlandlela uchaza izinto ezibalulekile eziyisisekelo zezitini ze-magnesia alumina spinel ezidingweni zakho zezimboni.
1. Incazelo Yezitini Ze-Magnesia Alumina Spinel
Izitini ze-Magnesia alumina spinel ziyizinto zokwenziwa eziphikisana ne-alkaline ezakhiwe ngokuyinhloko nge-magnesium oxide emsulwa kakhulu (MgO, 80%-92%) kanye ne-aluminium oxide (Al₂O₃, 3%-14%). Izigaba zazo eziyinhloko zekristalu—i-periclase kanye ne-magnesia-alumina spinel (MgO·Al₂O₃)—zakha isakhiwo esizinzile ngokushiswa kokushisa okuphezulu. Njengendlela ehlukile engena-chromium kunezingqimba zendabuko, izitini ze-magnesia alumina spinel zigwema ukukhishwa kwe-chromium enobuthi, zihambisana ngokugcwele nezindinganiso zemvelo zomhlaba wonke.
2. Izakhiwo Eziyinhloko Zezitini Ze-Magnesia Alumina Spinel
Izici ezivelele zezitini ze-magnesia alumina spinel zifaka:
- ① Ukuqina okuhle kakhulu kokushaqeka kokushisa, ukumelana nemijikelezo yokupholisa amanzi engu-12-20 ku-1100°C;
- ② Ukumelana okuphezulu kakhulu nokushisa okuphezulu, okunezinga lokuncibilika elingu-2135°C kanye nokungaguquguquki ngaphansi komthwalo >1700°C;
- ③ Ukugqwala okunamandla kanye nokumelana ne-slag ngokumelene ne-alkaline slags, amagesi ane-asidi, kanye nezinsimbi ze-alkali;
- ④ Amandla esakhiwo athembekile, anobuningi obukhulu obungu-≥2.90 g/cm³ kanye namandla okuchoboza abandayo angu-≥45 MPa.
3. Ukusetshenziswa Okuyinhloko Kwezitini Ze-Magnesia Alumina Spinel
Izitini ze-Magnesia alumina spinel zilungele izindawo ezishisa kakhulu: izindawo zokushintshana ze-simende rotary kiln, i-steel ladle linings, i-glass furnace regenerators, kanye ne-petrochemical furnace linings. Ukuguquguquka kwazo kwenza izitini ze-magnesia alumina spinel zifaneleke kokubili emisebenzini ye-alkaline kanye ne-mixed atmosphere.
4. Amathiphu Okukhetha Izitini Ze-Magnesia Alumina Spinel
Uma ukhetha izitini ze-magnesia alumina spinel, gxila emaphuzwini amathathu abalulekile: fanisa isilinganiso se-MgO/Al₂O₃ nesimo senqubo yakho, qinisekisa amapharamitha obuchwepheshe ayinhloko (ubuningi bobuningi, ukumelana nokushaqeka kokushisa), bese uhlola izitifiketi zekhwalithi yomhlinzeki.Beka phambili izitini ze-magnesia alumina spinel ezihlolwe ngesimo sakho sezimboni ukuqinisekisa ukusebenza kahle kanye nokuphila isikhathi eside kwenkonzo.
Izitini ze-Magnesia alumina spinel zihlanganisa ukusebenza kahle kanye nokusimama, okwenza zibe utshalomali oluhlakaniphile lwezimboni zesimanje ezishisa kakhulu. Khetha izitini ze-magnesia alumina spinel ezifanele ukuze uthuthukise ukuthembeka kwemishini futhi unciphise izindleko zokulungisa.
