Magnesite Composite Spinel Brick (ANKRAL Z1) /Excellent fire resistance/Good corrosion resistance/Excellent structural flexibility/Low porosity, and the strong ability to form the kiln skin
Magnesite Composite Spinel Brick (ANKRAL Z1)
Summary:
This brick grade represents a new generation of "heavy duty" cement rotary kiln bricks based on purest high-grade sintered magnesia and fused hercynite spinel.This innovative raw material concept gives ANKRAL Z1 superb refractoriness and corrosion resistance as well as outstanding structural flexibility due to the addition of the patented fused hercynite. ANKRAL Z1 is characterized by a very low apparent porosity which ensures a very low tendency of infiltration by alkaline salts or liquid clinker melt. An essential feature of this premium grade hercynite spinel brick is its ability to form coating which is not typical for premium grade spinel bricks. The positive effects of this protective mechanism on service life and kiln shell temperature are not achieved by conventional MA spinel bricks.
Product features:
1. Excellent fire resistance
2. Good corrosion resistance
3. Excellent structural flexibility
4. Low porosity, and the strong ability to form the kiln skin
