Relationship between Slag Phase and Softening & Melting Properties of Cohesive Zone

抄録

In this paper, Softening & Melting experiments with different charge ratios are carried out and compared with typical slag phase properties. The relationship between the charge ratio and the softening & melting properties is non-linear correlation. The liquid phase generation process of the slag corresponds to the softening zone and the viscosity change process of the slag phase after the liquid phase is fully generated corresponds to the melting zone. In the softening interval the properties of FeO–CaO–SiO₂ system play a dominant role, while in the melting interval the properties of FeO–CaO–Al₂O₃–SiO₂ system play a dominant role. This provides ideas for the study of the limiting links in the soft fusion zone of complex systems.
