Abstract: The quality of pellet has a great extent effect on the BF smooth operation. In this paper, Self-characteristics of iron ore powers used in pellet process were investigated. Then, the principles of ore-proportioning optimization basing on self-characteristics of iron ore during pelletizing were proposed. Schemes of ore-proportioning optimization were designed and a series of experiments on the schemes have been made for seeking the rational ore-proportioning scheme. The results show that there are great differences in the pelletizing properties of single iron ore podwer, and the object of improving pellet quality is reached through optimizing ore-proportioning, that lays a theoretical foundation and provides technical basis for improving pellet quality.

Abstract: In this paper, self-characteristics (the room-temperature characteristics and the high-temperature characteristic) of iron ores used in sintering, such as chemical composition, size distribution, assimilation, liquid phase fluidity, self-strength of bonding phase, etc, were studied. Then, the principles of ore-proportioning optimization basing on self-characteristics of iron ore during sintering were proposed. Schemes of ore-proportioning optimization were designed and sinter pot test were carried out.Results of sinter pot confirmed the method of optimizing ore proportioning based on iron ore self-characteristics. This work provides good countermeasure for improving sinter quality and reducing sinter cost as soon as possible, under the condition of making full use of the existing iron ore resources.
