Abstract
Effects of microsilica and reactive alumina type on flowability, flow decay and working time of Al2O3-SiC-C castables for blast furnace trough were investigated. The results show that at a targeted self flow values of (80 ± 10)%, water demand markedly decreases with increased microsilica addition. The nature of reactive alumina has a strong influence on flowability of the castables. Higher microsilica content contributes to a longer working time. The flow decays gradually until the working time and then drops abruptly. In addition, microsilica have positive effect on both cold strength and hot strength.
