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. The product is made of high quality synthetic spinel raw materials and special process , the product has high strength , good thermal shock resistance , thermal creep resistance, high softening temperature load characteristics , but also has a direct bonded magnesia chrome brick easy sticky skin hanging kiln characteristics to solve the magnesia-chrome brick cement kiln generated during the use of hexavalent chromium in environmental pollution problems

Feature

1.High thermal shock resistance stability, 2.Good corrosion resistance, 3.High mechanical strength at high temperature, 4. Good resistance to abrasion, 5.Good kiln coating adherence, 6. Chromium-free and pro-environment.
