Low and Special Cement Castables
We are involved in producing Low and special Cement Castables. It contents low cement, low calcium oxide content. Compared with the common castable, High Strength Castable Refractory consumes less water. Thus the density is much higher while the porosity is lower than common castable. It is different from traditional castables, these castables grade aggregated superfine with the same or similar chemical composition as the main material (with a particle size of less than 10 microns) replace most or all of the cement, and refined and scientifically optimized particles. Grading, fine powder, particle morphology and other factors.
Advantage
- High fire temperature and high operating temperature.
- These products are designed to sinter at a relatively low temperature and provide a high degree of alkali resistance at elevated temperatures.
- Low porosity and high bulk density.
- Flexural strength increases as the heat-treatment temperature increase.
- Improved fire-resistance and compressive strength, resistance to slag erosion
