摘要
通过优化基质中煅烧氧化铝或活性氧化铝、铝酸钙水泥、外加剂、板状刚玉细粉(或其他细粉 )的组成 ,可明显改善浇注料的性能 ;采用优化的基质体系 (MAS) ,可获得施工时间可控、加水量低 (振动浇注料为 3 .6 %~ 4.6 % ,自流浇注料为 4.0 %~ 5 .0 % )的高强度自流或振动浇注料 ,实现浇注料配方设计的菜单化 ;高稳定性美铝组合基质 (AIM)的出现 ,进一步简化了浇注料的配方设计 ,使同一种基质可满足振动或自流施工的作业要求 。
Fine and superfine matrix components such as calcined and reactive aluminas,calcium aluminate cements,dispersing additives and superfine tabular alumina can contribute significantly to the improvement of the performance of refractory castable in the aspect of low water demand,setting control and strength development.An optimized matrix system,i.e.,a Matrix Advantage System(MAS),makes it possible to get low-moisture(the vibration castable is 3.6%~4.6% while the self-flow castable is 4.0%~5.0%),high strength vibration and self-flow castables,with controllable setting behavior.Matrix with high stability can,when customized through new developed Alcoa Integrated Matrix(AIM),enable the design of castable formulation even simpler and refractory castable more robust.Same AIM can satisfy the workability as required in the vibration and self-flow installations.Substituted by different Al 2O 3 based aggregates,the overall performance of castable can be easily steered to meet the specific application requirements.
