Tabular corundum, amadziwikanso kutisintered tabular alumina, ndi mawonekedwe apamwamba a alumina (Al2O3) omwe amakonzedwa kuti akhale ndi amawonekedwe apadera a tabular, kapena athyathyathya.Zimapangidwa ndi sintering (kutentha popanda kusungunuka) ufa wapamwamba wa alumina pa kutentha pamwamba pa 1900 ° C, zomwe zimapangitsa kuti particles za alumina zikule ndikupanga makristasi akuluakulu, ophwanyika, ngati mbale.

Kugwiritsa ntchito: Tabular corundum imagwiritsidwa ntchito kwambiri pazinthu zotsutsa kwambiri m'magawo azitsulo, kuponyera, petrochemicals, njerwa mpweya, ladle linings, castables, prefabricated mbali, zoumba ndi zina..Ndibwino kwambiri kupanga refractory yaiwisi.Tabular corundum imagwiritsidwa ntchito ngatiRefractory aggregateangagwiritsidwe ntchito osakaniza spinel, calcined adamulowetsa aluminiyamu ndi zomangira monga simenti, dongo kapena utomoni.Njerwa zokonzedwa bwino za corundum zimakhala ndi zonyansa zochepa (monga SiO2), kuchulukitsidwa kwakukulu ndi katundu wabwino wa thermodynamic, kupanga njerwa za corundum Njerwa zimagonjetsedwa ndi kutentha, mankhwala ndi kuwonongeka kwapangidwe chifukwa cha ntchito ya gasifiers ndi ng'anjo zina za mafakitale. | ||
Ubwino wake:mkulu refractoriness;kukana dzimbiri;kukana kukokoloka kwakukulu;mkulu matenthedwe kukana mantha;kulimba kwakukulu, kulimba kwabwino;khola mankhwala katundu;kukana kukokoloka kwa slag zamchere, kukana kukokoloka kwa slag, komanso kukana kukokoloka kwachitsulo chosungunuka;Kugonjetsedwa ndi kukokoloka ndi chitsulo chosungunuka komanso mpweya wabwino wodutsa. |
