Ultra Low Cement Castables

ORAMON ULCC is a series of ultra-low cement castables, which contain even lower level of cement than low cement castables. They have high strength at all temperature levels. These Castables are used in locations needing high abrasion resistance. Low CaO content ensures high refractoriness and Excellent hot strength and MOR at all temperatures. Lower apparent porosity after firing offers better corrosion resistance, High abrasion, spalling resistance and volume stability.
