Magnesia chrome bricks are refractory products with magnesium oxide and chromium trioxide as the main components, and periclase and spinel as the main mineral components. This type of brick has high refractory resistance, high high-temperature strength, strong resistance to alkaline slag erosion, excellent thermal stability, and appropriate adaptability to acidic slag. The main raw materials for manufacturing magnesia chrome bricks are sintered magnesia and chromite. The purity of magnesia raw materials should be as high as possible, and the chemical composition of chromite should be: Cr2O3: 30~45%, CaO: ≤1.0~1.5%.
Magnesia chrome brick products have the characteristics of high high-temperature structural strength, high load softening temperature, and strong resistance to chemical attack. It has high refractory temperature, strong resistance to alkaline slag, and excellent high-temperature volume stability. The standard dimensions are accurate and easy to construct. Dimensions can be processed according to drawings. The excellent product characteristics of magnesia chrome bricks determine the wide range of uses of the products, and they play an irreplaceable role in the construction of high-temperature kilns.
