Izitena zomlilo ze-alumina silica luhlobo lwezinto zokuchasa i-alumina silica, izitena zokuchasa i-alumina silicate zineempawu zokuchasa okuphezulu, ukumelana nokukhukuliseka okuhle kunye namandla aphezulu. Izitena zokuchasa i-alumina silicate ziquka iintlobo ezininzi zezitena zomlilo ezifana nezitena ze-silica, izitena zomlilo, izitena ze-alumina eziphezulu, izitena ze-mullite kunye nezitena ze-corundum. Izitena zomlilo ze-alumina silica zingasetyenziselwa zonke iintlobo zezixhobo zobushushu.
Uhlu lwezitena zomlilo ze-Alumina Silica
Ngokwendlela yokwandisa umxholo ukusuka kwi-SiO2 ukuya kwi-Al2O3, izitena zomlilo ze-aluminium silicon zahlulwe zibe ziindidi ezilandelayo
Isitena seSilica: umxholo weSiO2 ungaphezulu kwe-93%,
Izitena zodongwe: umxholo we-Al2O3 yi-30%-48%,
Isitena se-alumina esiphezulu: umxholo we-Al2O3 ungaphezulu kwe-48%,
Izitena ezininzi: umxholo we-Al2O3 mkhulu kune-72% okanye ulingana ne-19%, kwaye umxholo we-SiO2 mkhulu kune-28% okanye ulingana ne-19%.
Isitena seCorundum: umxholo we-Al2O3 ungaphezulu kwe-90%.
Ukusetyenziswa kwe-Alumina Silica Fire Brick
Izitena zeSilica zisetyenziswa kakhulu ekwakheni i-oven ye-coke, i-oven yeglasi, i-oven ye-ceramic, i-oven ye-carbon calcinations kwaye azifanelekanga ukusetyenziswa kwizixhobo zokufudumeza ezinokuguquguquka kobushushu obungaphantsi kwama-600 ℃.
Izitena zodongwe zihlala zisetyenziswa kwi-blast furnace, i-hot blast heater, i-heating furnace, i-power boiler, i-lime kiln, i-rotary kiln, i-ceramic kiln kunye ne-calcining kiln.
Izitena ze-alumina eziphezulu zisetyenziswa kakhulu kwimveliso yentsimbi, kushishino lweentsimbi ezingenayo i-ferrous kunye neminye imboni.
Izitena zeMullite zisetyenziswa kuzo zonke iintlobo ze-furnace ezifakwe ubuso obushushu kunye ne-backing lining kushishino lwe-metallurgical, kushishino lwe-petrochemical, kushishino lwezixhobo zokwakha, kushishino lwe-ceramic, nakushishino lwe-mechanical.
Izitena zeCorundum zingasetyenziswa kwi-blast furnace, kwi-hot blast stove, kwi-glass furnace njl.
