REFRAMON
Low Cement Castables
Reframon LC is a low cement Castable having high strength at all temperature levels. These Castables are used in locations needing high abrasion resistance.
Ultra Low Cement Castables
Reframon ULCC are ultra-low cement castables which contain even lower level of cement than low cement castables.
Above LC/ULCC Castables offers following advantages:
- Low CaO content ensures high refractoriness.
- Excellent hot strength and MOR at all temperatures.
- Lower apparent porosity after firing offers better corrosion resistance.
- High abrasion and spalling resistance.
- High volume stability.
