Corundum Mullite Castable Description
Corundum mullite refractory castable ndi mtundu wa zida zamphamvu zopanda mawonekedwe zogulitsa ku RS Company, zomwe zitha kugwiritsidwa ntchito mu uvuni wa simenti. Corundum mullite castables amatha kuchita zinthu zapamwamba monga kuphwanya kwakukulu, kukhazikika kwa kutentha kwambiri, kukana kugwedezeka kwamafuta, kuvala komanso kukana kukokoloka kwamankhwala pamakina a boiler yayikulu yamagetsi ndi zida zina zotentha kwambiri. refractory corundum mullite castable angagwiritsidwe ntchito mu ng'anjo zitsulo, simenti uvuni, galasi ng'anjo, chitsulo kupanga ng'anjo, ceramic tunnel uvuni ndi zina zotero.
Katundu wa Corundum Mullite Castable
- Mphamvu zazikulu,
- Kukana kwamphamvu kuvala,
- Kukana kukokoloka kwabwino,
- Kukhazikika kwabwino kwa kutentha kwa kutentha,
- Kukana kutentha kwakukulu.
Njira Yopangira Corundum Mullite Castable
Zida zazikulu za corundum mullite zotayidwa ndi zopepuka za aluminium oxide aggregate, ore apamwamba kwambiri achilengedwe a mullite ore, ndi simenti ya calcium aluminate monga cholumikizira. corundum mullite refractory castable imapangidwa kudzera pakuwotcha kwambiri ndi ng'anjo yapamwamba yamafakitale. corundum mullite flexural mphamvu ndi compressive mphamvu kuwonjezeka koyamba ndi kuchepa ndiye ndi kuwonjezeka kutentha kutentha kutentha. Ndipo mphamvu ya alumina yaying'ono ikafika 5%, mphamvu yosinthika imafika pamwamba.
Kupangidwa kwa Corundum Mullite Castable
Zomwe zili mu Al2O3 ndizoposa 90%, ndi corundum mullite kutchinjiriza kuponyedwa ndi corundum monga gawo lalikulu la kristalo limasakanizidwa ndi dispersants yoyenera, coagulants, ulusi wosapanga dzimbiri, zomwe zimaphatikizidwa motsatira ndondomeko yolimba. Refractory corundum mullite castable imakhala ndi mawonekedwe ambiri, monga kulimba kwa kutentha kwambiri, kukana kuvala ndi kutsutsa, kuwongolera kutentha kwambiri, kukana kutentha, kukana dzimbiri, kusindikiza bwino komanso kukhazikika koyambirira.

- Kugwiritsa ntchito Corundum Mullite Castable
- Corundum mullite refractory castable ali ndi mawonekedwe a kukula kwa yunifolomu, kukana kwambiri kwa kutentha kwa kutentha, kukhazikika kwa kutentha kwakukulu, mphamvu ya kutentha kwambiri, kukana kwambiri pansi pa katundu, kutsika kwapang'onopang'ono, kutsika kwapamwamba, kuphwanya mphamvu, kutsika kwa mzere wozungulira, kuuma kwakukulu, zabwino. kukana dzimbiri mankhwala, spalling ndi kuvala kukana. Chifukwa cha zilembo, corundum mullite kutchinjiriza castable ndi cholimba ntchito ndipo chimagwiritsidwa ntchito zosiyanasiyana mafakitale ng'anjo, kutentha ng'anjo ndi mbali zina zofunika kutentha mkulu, monga:
- Boiler, ng'anjo yoyaka moto, chitofu choyaka moto, ng'anjo yowotcha,
- Mng'anjo ya ceramic, uvuni wa simenti, woyatsira malasha,
- Khomo la ng'anjo, kutsegula kwa chakudya, ng'anjo zachitsulo, ng'anjo zopangira chitsulo,
