Product description
Castable fire cement have high mechanical strength and good resistance to thermal shock and abrasion. After drying and calcining at high temperatures, the body density will not shrink. castable fire cement not only have high strength at normal temperature, but also use white cement to combine at medium temperatures, so the strength will not change
Application of castable fire cement
It has excellent properties such as good thermal expansion resistance and strong peeling resistance. Mainly used in thermal equipment such as high furnaces, soaking furnaces, and heating furnaces.
The type and dosage of clay binder have an important impact on its performance. The choice of soft clay binder requires good plasticity, strong dispersion, good adhesion, wide sintering temperature range, and high refractoriness.
