Low Thermal Conductivity Magnesia Alumina Spinel Bricks
Summary:
Magnesium Aluminum Spinel Bricks are made from high-purity magnesium sand and fused magnesium aluminum spinel as raw materials, which are formed under high pressure and sintered at high temperature. It has strong resistance to high temperature chemical erosion, excellent alkali resistance, high load softening temperature, good thermal shock stability, strong erosion resistance, and high strength.
Product features:
- 1.Strong resistance to high temperature and chemical erosion
- 2.High load softening temperature, good thermal shock stability
- 3.Strong erosion resistance and high strength
Range of application:
Transitional Zone of Cement Rotary Kiln
