Abstract

The enhanced properties of refractory castables are usually designed by the addition of multifunctional mineralizers and fine powders to satisfy the requirements of steelmaking industry. In this work, the effects of fine composite powders addition on properties of corundum-spinel refractory castables were investigated. Phase composition, microstructure, physical and mechanical properties of corundum-spinel refractory castables with different contents of fine composite powders were characterized. The results showed that the smaller spinel in the fine composite powders improved the sintering activity of the spinel particles, which had an influence on the morphology and the distribution of CA₆ for the limited space. As the consequence of this, the cracks caused by in situ CA₆ generation decreased and the firm link between particles was gained, finally the strength of castables containing fine composite powders improved.
