  Features   1. Low CementRefractory Castable has high density and low porosity. 
2. High normal temperature cure property, intensity will be increased after medium temperature and high temperature. Three or five times more than common Refractory Castable.
3. Good volume stability under high temperature.   Usage:  Material for metallurgy, petroleum, chemical and other industries kilns
Part of refining installation, like ladle cover
