Physicomechanical properties of medium-cement refractory castables containing chamotte-silicon carbide fillers tested for practical applications

Abstract

The physicomechanical properties of chamotte and silicon carbide fillers are compared and the compositions for medium-cement refractory castables using mixtures of these fillers are formulated. Rheological features and heat release kinetics of castables are studied and the effect of sintering temperatures on the properties of castables is discussed. The newly designed castables were used to fabricate paving blocks for brick-burning tunnel kilns.
