铁矿粉供应的复杂多变加剧了烧结配矿的难度,易导致烧结生产及烧结矿性能的不稳定。传统的烧结杯试验配矿方法费时费力,研究开发新的优化配矿方法替代传统烧结杯试验配矿方法是钢铁企业提高配矿效率、实现降本增效的重要途径。详细介绍了铁矿粉常温性能、铁矿粉高温性能、热力学计算等指导烧结配矿的方法,分析了主要烧结配矿方法的技术特点,对烧结配矿研究方向进行了展望。指出铁矿粉的高温性能是基于铁矿粉基础工艺性能的烧结优化配矿方法的核心。查明铁矿粉关键基础工艺性能与烧结产质量的关系,是解决烧结优化配矿可靠性的关键。 相似文献

In order to obtain good sintering performance, it is important to understand sintering properties of iron ores. Sintering properties including chemical composition, granulation and high-temperature behaviors of ores from China, Brazil and Australia. Furthermore, several indices were defined to evaluate sintering properties of iron ores. The results show that: for chemical composition, Brazilian ores present high TFe, low SiO2, and low Al2O3 content. For granulation, particle diameter ratio of Brazilian ores are high; particle intermediate fraction of Chinese concentrates are low; and average particle size and clay type index of Australian ores are high. For high-temperature properties, ores from China, Brazil and Australia present different characteristics. Ores from different origins should be mixed together to obtain good high-temperature properties. According to the analysis of each ore′s sintering properties, an ore blending scheme (Chinese concentrates 20%+Brazilian ores 40%+Australian ores 40%) was suggested. Moreover, sinter pot test using blending mix was performed, and the results indicated that the ore blending scheme led to good sintering performance and sinter quality. 相似文献
