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