Yakadzika inokwira yakakwirira alumina zvidhinha yeanopisa blast chitofu

Yakadzika inofamba uye yakakwirira alumina zvidhinha zvinhu zvepamusoro-giredhi zvinokanganisa zvakagadzirwa nealumumina, fused corundum, uye fused mullite seyakanyanya mbishi zvigadzirwa.

Features

1. Refractoriness

Iyo Refractoriness yezvakaderera-zvinokambaira uye zvakakwirira-alumina zvidhinha zvakakwirira kupfuura izvo zvevhu zvidhinha uye semi-silika zvidhinha, inosvika 1750 ~ 1790 ℃, inova yepamusoro-giredhi refractory zvinhu.

2. 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.

3. Slag kuramba

Yakadzika inokwira uye yakakwirira alumina zvidhinha zvine zvimwe Al2O3, iri padyo nekusarerekera zvinhu zvinopesana, uye inogona kudzivisa kukukurwa kweacidic slag uye alkaline slag. Nekuti ine SiO2, kugona kurwisa alkaline slag haina kusimba pane iyo yeacidic slag.

shandisa

Inonyanya kushandiswa kumadziro ekuputika kwevira, kupisa kwemoto unopisa, machira emoto emagetsi, mafirita emoto, mafoshoro ereverberatory, uye mota dzemoto.
