本文讨论了熔渣发泡现象的实质 ,建立了泡沫渣发泡幅度的理论模型 ,结合实验数据讨论了模型参数。结果表明 :发泡幅度随熔渣粘度增大及表面张力的减小而增大 ,渣中悬浮的固相粒子对泡沫稳定有着特殊贡献 In this paper, the essence of the phenomenon of slag foaming is discussed. The theoretical model of foam foaming amplitude is established. The model parameters are discussed with the experimental data. The results show that the foaming amplitude increases with the increase of the slag viscosity and the decrease of the surface tension, and the solid particles suspended in the slag have a special contribution to the foam stability
