Grade l High Alumina Bricks (T-38)

Yakakwirira alumina zvidhinha tsananguro

Kana zvinyorwa zveAl2O3 zvakakwirira kudarika 90%, inonzi corundum brick. Nekuda kwezviwanikwa zvakasiyana, zviyero zvenyika dzakasiyana-siyana hazvina kunyatsoenderana. Semuenzaniso, nyika dzeEurope dzinoti muganho wakaderera weAl2O3 wepamusoro-alumina refractories ndeye 42%. MuChina, zvidhinha zvakakwirira zvealuminium zvinowanzoreva zvidhinha zvinoramba zvine zvinyorwa zveAl2O3 zvinopfuura 48%. Izvo zvinonyanya kugadzirwa nemhando yepamusoro-giredhi bauxite, iyo ine zvicherwa zvakaita sediaspore, bomerite, kaolinite, etc. Ivhu rakapfava kana semi-nyoro rinowedzerwa kune yakakwirira-aluminium clinker sebinder kutanga batching uye kusanganisa, uye ipapo inoumbwa, yakaomeswa, uye pakupedzisira inodzingwa. Iyo refractoriness yealumina yakakwira zvidhinha ingangoita 1770 ℃, uye tembiricha yekunyorovesa i1420 ℃-1550 ℃. Kazhinji high alumina zvidhinha LZ-80, LZ-75, LZ-65, LZ-55, LZ-48, etc. Inonyanya kushandiswa lining blast furnace, hot blast furnace, ore-heat furnace, electric furnace roof, blast. choto, choto chinodzoreredza uye choto chinotenderera. Pamusoro pezvo, zvidhinha zvakakwirira zvealumina zvinoshandiswawo zvakanyanya seyakavhurika-yevhu yekuchengetera kupisa zvidhinha, mapulagi ekudira masisitimu, zvidhinha zvenozzle, nezvimwe.
