Product Details
Performance & Advantages:
Low creep rate;
High refractoriness under load ;
Excellent thermal shock resistance;
Strong alkali resistance;
Abrasion & erosion resistance.
Applications:
Serves as high-efficiency heat exchange media in the regenerator of hot blast stoves, preheating blast furnace air to ultra-high temperatures (typically 1100-1350°C) for large-scale hot stoves in steel plants.
