主　　题：fluidity gunned refractory rheological behavior 

摘      要：Study on rheological properties of gunned refractory is an effective way to optimize the quality of repaired layer and gunning operation. The fluidity of refractory was quantitatively evaluated as well as the rheological behavior of refractory particle-water suspensions. The relationship between the fluidity of refractory particle-water suspension and that of gunned refractory, and the relationship between the fluidity and adhesion ability of gunned refractory were studied. The experiments were carried out with a special rheometer and gunning machine. The results show that there is strong influence of some parameters on the rheological behavior of gunned refractory and gunning process. Interactions between particles and water that lead to the formation of gelatinous structures in this suspension are discussed.
