Abstract：Based on micro sintering experiments, the high temperature properties of six kinds of iron ores in a certain steel plant, such as the assimilation and liquid phase fluidity, were measured and compared, and their influencing factors were also analyzed. Then according to their high temperature properties, the ore matching principles were put forward and four groups of optimizing ore matching schemes were designed, based on which, sinter pot tests were carried out to verify the application of these schemes. Results show that, compared with the original ore blending scheme in the steel plant, better sinter production and quality as well as lower sintering cost were obtained by ore matching optimization and the feasibility of sintering proportioning optimization methods based on high temperature characteristics of the six types of iron ore fines were verified, which provides a theoretical basis and technical support for optimizing the sintering proportioning in this steel plant.
