INFLUENCE OF ANDALUSITE ADDITION AND PARTICLE SIZE ON PROPERTIES OF BAUXITE-SILICON CARBIDE BRICK

摘要

Bauxite-silicon carbide brick is widely used in the transition zone of cement rotary kiln in China. In this work, the influences of andalusite addition and particle size on thermal shock resistance and refractoriness under load of the bauxite-silicon carbide bricks are investigated. The results show that appropriate addition of andalusite is beneficial for increasing thermal shock resistance and refractoriness under load.
