Advantage of High-strength wear-resistant refractory castable
1. The High-strength wear-resistant refractory castable composition of the castable is stable and the service life is long.
2. The castable forms a liquid phase during the sintering process, which helps to promote the compactness of the structure and has strong integrity
3. High-strength wear-resistant refractory castables have good thermal stability, wear resistance and erosion resistance
