Magnesite Refractory Material Direct Bonded Magnesia-chrome Brick for Cement Kiln
Introduction:
Magnesia chrome brick is refractory products containing magnesium oxide (MgO) and chromium oxide (Cr2O3) as the main components, and periclase and spinel are the main mineral components.
This type of brick has high refractoriness, high temperature strength, strong resistance to alkaline slag, excellent thermal stability, and certain adaptability to acidic slag.
