摘　　要：基于微型烧结试验,测定、比较和分析了国内某钢厂烧结生产常用6种铁矿粉的同化性和液相流动性等高温特性及其影响因素,进而根据其高温特性提出相应互补优化配合原则,设计了4组烧结优化配矿方案并进行了烧结杯试验。结果显示,优化配矿方案的烧结矿产量、质量指标均比基准方案优良,烧结成本比基准方案低,这表明基于铁矿粉同化性和液相流动性对所研究的6种铁矿粉能够进行有效的优化配矿,也为该钢厂烧结优化配矿提供了理论依据和技术支持。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.
