Kuumbwa kwe yakakwirira alumina zvidhinha

Iyo mineral inoumbwa yealumina yakakwira zvidhinha ndeye corundum, mullite uye girazi chikamu. Izvo zvirimo zvinoenderana nechiyero cheAl2O3 / SiO2 uye rudzi uye huwandu hwekusachena. Giredhi rezvidhinha refractory rinogona kuiswa maererano nezviri muAl2O3. Izvo zvigadzirwa zvechisikigo ore yeakakwira bauxite uye sillimanite, pamwe ne clinker calcined nealumina, sintered alumina uye synthetic mullite muzvikamu zvakasiyana. Kazhinji inogadzirwa ne sintering process. Asi zvigadzirwa zvikuru zvakasanganiswa zvidhinha zvakakandwa, zvidhinha zvegranular, zvidhinha zvisina kupiswa, uye zvidhinha zvisingagadzirwe. High-alumina refractory zvidhinha inoshandiswa zvakanyanya musimbi, isina-ferrous simbi uye mamwe maindasitiri.
