Abstract

In order to improve the knowledge in iron ore properties to sintering, Ferrous Technology Center (CTF) at Vale S/A has been studying some parameters to characterize the sinter feed at high temperatures such as: (i) reactivity between iron ore and CaO, (ii) fluidity of liquid phase, and (iii) intensity of formation of SFCA phase. These properties are important to design the optimum iron ore blend to the sintering process. In the CTF there are two types of equipment used for these analyses: an Infrared furnace and a Fusibility furnace. The objective of this study was to characterize different commercial iron ores and to present, as example of application, a real case of a Vale´s customer.
