The aggregation behavior of particles affects the melting process and performance of metallic materials. The capillary interaction between particles on the surface of melts is studied based on Kralchevsky–Paunov model and simulation of contact line profile around particle. The calculated capillary force based on Kralchevsky–Paunov model indicates that the tendency for affecting the aggregation behavior is particle–melt contact angle > particle radius > distance between particle pairs > particle density > surface energy of melts. The chemical compositions of liquid steel superposition effect on the capillary force is great, and it is found that the capillary force between Al2O3 particle pair decreases with increasing O content, but increases with increasing S content. The capillary force between MgAl2O4 particle pair increases with increasing O and S contents. The calculated results are compared with the experimental results. It is found that the change trends of calculated capillary force and attraction force are same, but a majority of calculated capillary force is smaller than the observed one. The discrepancy between them is analyzed systematically in terms of selective attraction based on a simulation of the contact line profile for unwettable particles.

高温熔体表面颗粒间毛细管相互作用的研究
颗粒的聚集行为影响金属材料的熔化过程和性能。基于Kralchevsky-Paunov模型和颗粒周围接触线轮廓的模拟，研究了熔体表面颗粒之间的毛细作用。基于 Kralchevsky-Paunov 模型计算的毛细管力表明，影响聚集行为的趋势是粒子 - 熔体接触角 > 粒子半径 > 粒子对之间的距离 > 粒子密度 > 熔体的表面能。钢液化学成分叠加对毛细管力的影响很大，发现Al 2 O 3之间的毛细管力颗粒对随着 O 含量的增加而减少，但随着 S 含量的增加而增加。MgAl 2 O 4颗粒对之间的毛细管力随着O和S含量的增加而增加。将计算结果与实验结果进行比较。发现计算毛细力和吸引力的变化趋势相同，但大部分计算毛细力小于观察到的毛细力。基于对不可润湿颗粒的接触线轮廓的模拟，在选择性吸引方面系统地分析了它们之间的差异。
