Yakaumbwa yakakwirira alumina zvidhinha

Special-shaped high alumina brick grade three high alumina brick is a kind of refractory material, the main component of this refractory brick is Al2O3.

Kana Al2O3 zvemukati zvakakwirira kupfuura 90%, inonzi corundum zvidhinha. Nekuda kwe zviwanikwa zvakasiyana, zviyero zvemunyika hazvina kuenderana zvakakwana. Semuenzaniso, nyika dzeEuropean dzinoisa muganho wezasi weAl2O3 zvemukati zveakakwira-alumina Refractories pa42%. MuChina, zvinoenderana nezviri mukati meAl2O3 mune yakakwirira alumina zvidhinha, inowanzo kuve yakakamurwa kuita matatu mamaki: Giredhi I──Al2O3 zvemukati> 75%; Giredhi II──Al2O3 zvemukati zviri 60 ～ 75%; Giredhi III──Al2O3 zvemukati zviri 48 ～ 60%.

Yakaumbwa yakakwirira alumina zvidhinha

Product Features

a. Refractoriness

Iko kudzvanyirira kweakakwira alumina zvidhinha kwakakwirira kupfuura izvo zvevhu zvidhinha uye semi-silika zvidhinha, inosvika 1750 ~ 1790 ℃, inova yepamusoro-mhando inoratidzira zvinhu.

b. Takura tembiricha inopfavisa

Nekuti zvigadzirwa zve-alumina zvine Al2O3 yakakwira, marara mashoma, uye mashoma egirazi fusible miviri, tembiricha inodzikamisa mutoro iri pamusoro kupfuura yezvidhinha zvevhu. Nekudaro, nekuti mullite makristasi haagadzi chimiro chenetiweki, tembiricha inodzikamisa tembiricha haisati yakakwira seiya yezvidhinha zvesilica.

c. Kurwisa kweSlag

Yakakwira alumina zvidhinha zvine Al2O3 yakawanda, iri padhuze nekusarerekera zvinhu zvinopesana, uye inogona kudzivisa kukukurwa kweacidic slag uye alkaline slag. Nekuda kwekuisirwa kweSiO2, kugona kurwisa alkaline slag haina kusimba pane iyo yeacidic slag.

Kushandiswa Kwechigadzirwa

Inonyanya kushandiswa kumadziro ekuputika kwevira, kupisa kwemoto unopisa, machira emoto emagetsi, mafirita emoto, mafoshoro ereverberatory, uye mota dzemoto. Pamusoro pezvo, zvidhinha zvealumumina zvakare zvinoshandiswa zvakanyanya seyakavhurika imba yekuvharisa zvidhinha, mapuragi ekudurura masisitimu, zvidhinha zvemhino, nezvimwe zvakadaro, zvakadaro, mutengo weakakwira alumina zvidhinha wakakwirira kupfuura izvo zvevhu zvidhinha, saka hazvidikanwe kushandisa yakakwirira alumina zvidhinha apo zvidhinha zvevhu zvinogona kusangana nezvinodiwa.
