摘要/Abstract

摘要： 以无料钟布料过程中物料运动机理为基础，改进了料流轨迹的修正方法，提出了料面形状计算的新方法.高炉布料模型在计算过程中考虑了炉料特性、焦炭塌落等对料面形状的影响，使计算结果更符合实际布料.结合生产实践需求，计算出了各种不同布料制度下炉料的料面形状、炉料径向分布、径向矿焦比等参数，提出了高炉区域焦炭负荷指数，更加直观、形象地对比各种布料制度.利用该模型可解答大型高炉生产上存在的问题，对高炉的实际生产提出了实用性建议，为高炉操作人员调整布料制度提供了理论指导.

关键词: 大型高炉, 布料模型, 料流轨迹, 料面形状, 布料制度

Abstract: A new method of calculating charging profile was proposed which based on the mechanism of material movement in the charging process and improved the correction method of material flow path. As the model takes into account the effects of charge characteristics， coke collapsing and other factors on the charging profile， it makes the simulation results more accurate in practice. When its setup combines with industrial conditions， the model can calculate the parameters of charging profile， radial distribution of material， radial O/C rate and etc. under different charging systems. The area coke load index of blast furnace (BF) has been defined which makes it more evident when comparing the difference of various charging system. Using the model， some existing problems in large BF could be solved and also the practical suggestion can be proposed for the actual production. The model could further provide theoretical guidance of adjusting charging system for BF operators.

Key words: large blast furnace, burden charging model, material flow path, charging profile, charging system
