Dab tsi yog kev ua haujlwm ntawm kev siv magnesia chrome cib?

Magnesia chrome cib yog cov khoom siv refractory uas muaj Cr2O3≥8% ua los ntawm kev ntxiv chromite rau sintered magnesia ua raw khoom. Lub ntsiab ntxhia theem yog periclase thiab chromium-muaj spinel (MgO.Cr2O3).

Magnesium chrome bricks muaj qee yam kev tiv thaiv alkaline slag yaig, zoo ntim ruaj khov ntawm qhov kub thiab txias, thiab me me shrinkage thaum reburned ntawm 1500 ° C. Lub ntsiab tsis zoo yog tias tom qab chromium spinel absorbs hlau oxide, cov qauv ntawm lub cib hloov, ua rau “inflation” thiab ua kom lub cib puas.

Magnesium chrome bricks feem ntau yog siv los tsim tooj liab smelting furnaces, hluav taws xob rauv, rotary kilns thiab qee qhov chaw ntawm qhov cub qhib.
