Investigation into Using Low-to Medium-Grade Bauxite-based Homogenized Grogs to Prepare the New-generation of Castables Used in Large-scale Dry-process Cement Rotary Kilns

摘要

The new-generation of castables used in the linings of large-scale Dry-process Cement Rotary Kilns have been investigated in this paper by using low-to medium-grade bauxite-based homogenized grogs as aggregates. Comparing with traditional castables using high-grade crude bauxite clinker as aggregates, it is found that new castables demonstrated stable performance and all indexes can satisfy the demand of service performance completely. Using the new-generation of castables, the operation rate of Cement Rotary Kilns can be improved. It will be the trend of the castables.
