Chii refractory tembiricha yepamusoro alumina zvidhinha?

Iyo tembiricha yekuramba yezvidhinha zvevhu ndeye 1380-1570 ° C, uye tembiricha yekuramba yealumina yakakwira zvidhinha ndeye 1770-1790 ° C. Pane zvinhu zvakawanda zvinoda kutariswa kana uchitenga zvidhinha zvinoramba. Kubva pamakore edu mazhinji echiitiko, tinoyeuchidza munhu wese kuti asarudze zvakakodzera zvidhinha zvinoramba. Chekutanga pane zvese, zvinoenderana nechikamu chekushandiswa kwechidhinha chinoramba, tembiricha yekushanda sintering, tembiricha yekunyorovesa mutoro, kudzikama kwehukuru hwetembiricha, kupenengura kuramba, tembiricha yepamusoro inokambaira, uye simba rekumanikidza. Aya ndiwo akanyanya kukosha zvivakwa…
