Semi Bonded MgO Cr2O3 Magnesite Bricks Corrosion Resistance Fire Resistant Bricks
Semi-bonded MgO-Cr2O3 Brick
Semi-bonded MgO-Cr2O3 Brick/Dense and low porosity/Superior thermal shock resistance/Strong resistance to slag erosion
Summary:
Semi-bonded MgO-Cr2O3 Brick is a product with excellent corrosion resistance and peel resistance, which is synthesized by electric fusion method using magnesia chrome spinel, high-purity magnesia sand, high-purity chromium concentrate, and composite high-temperature toughening agent. It is made by high-pressure forming and high-temperature sintering.
Product features:
- 1.Dense and low porosity
- 2.High temperature strength and superior thermal shock resistance compared to Fusd-bonded MgO-Cr2O3 Brick
- 3.Strong resistance to slag erosion
Range of application:
Used for the working lining of the key locations of RH, VOD, AOD furnaces and copper flash furnace
