Slag Structure of High Alumina Blast Furnace Slag

The physicochemical properties of slag at high temperature are closely related to its structure, which are mainly reflected in the following aspects: (1) Melting property refers to the chemical reaction of each other to form liquid phase under the appropriate temperature and atmosphere conditions, and it is the process of the transition of ordered oxide crystal into a disordered liquid phase. (2) The fluidity and conductivity reflect the migration of ions and ion clusters and the adjustment of slag structure. (3) The surface properties are also related to the distribution of ions and clusters in slag structure of the surface layer. (4) The desulfurization performance is related to the distribution of free oxygen ions in slag.
