Research Abstract |
The quality of iron ore sinter has effects on blast furnace performance. It is well known that the iron ore with higher amount of alumina decreases the strength of sinter. The main phases of the sinter are hematite, magnetite, silica-ferrite of calcium and aluminum (SFCA) and silicates. The strength of sinter is closely related to the boundary structure between SFCA and other minerals. This study adopted EBSD analysis to clarify the crystallographic orientation relationship between constituent minerals (hematite and magnetite) and SFCA.
