出铁沟高温自流修补料的研制与应用

Development and application of hot self-flow castable for trough

对高炉出铁沟易出现开裂现象作了分析，研究了临界颗粒粒度、结合剂和悬浮剂的种类对高温自流修补料性能的影响。

Crack of troughs for blast furnace was analyzed in this paper. Influences of critical grain size,bonding agent and suspending agent on performance of the hot self-flow castable was studyed.Al2O3-SiC-C hot self-flow castable was developed.
