Description
Magnesia-chrome bricks are alkaline refractory products mainly composed of magnesium oxide (MgO) and chromium oxide (Cr2O3), with periclase and spinel as the primary mineral components. These bricks have high refractoriness, high-temperature strength, strong resistance to alkaline slag erosion, excellent thermal stability, and a certain degree of adaptability to acidic slags.
