Magnesia-iron spinel bricks use high-purity magnesia sand and Al-Fe spinel sand as the main raw materials through reasonable proportioning, high-pressure molding, strictly control over the firing temperature and firing atmosphere to make the products have good flexibility and thermal shock stability, and no hexavalent chromium pollution for cement kiln burning zone.
Features
High Compressive Strength; Good Thermal Shock Resistance; Environment Friendly; Strong Resistance to Permeability.
