摘　　要：高炉布料制度需要依据炉况状态适时调整。布料器旋转角度与环数的组合调整方式使布料矩阵的选择具有多种方式,角度与环数的具体调整幅度也存在选择空间,这将增加高炉上部调剂的主观性和随机性,不利于高炉的稳定顺行。为解决上述问题,提出一种结合高炉历史数据追溯与数值模拟的布料制度优化方法,通过对高炉近三年的数据进行分析,以炉况稳定性为依据优选出部分布料矩阵,而后利用数值模拟手段,对基于上述矩阵条件的料层分布进行图形可视化和特征参量定量化,进一步对比分析优选结果。优选矩阵以及所对应的特征信息可构成布料矩阵备选库,这将增强矩阵调整的可靠性和选用依据,并固化矩阵使用选项,有助于促进高炉稳定顺行。The blast furnace charging system needs to be adjusted in time according to the state of the furnace. However, the combined adjustment method of angle and ring number makes the selection of burden distribution matrix in many ways. There is also room for the selection of the specific adjustment range of angle and ring number, which will increase the subjectivity and randomness of the BF upper adjustment, and is not conducive to the stability and smooth operation of blast furnace. In order to solve the above problems, a charging system optimization method combining BF historical data traceability and numerical simulation is put forward. By analyzing the data of BF in the past three years, a part of the burden distribution matrix is selected based on the stability of the furnace condition. Then based on the above matrix conditions, the numerical simulation is used to graphically visualize and quantify the layer distribution so as to further verify the preferred results. The preferred matrix and corresponding feature information can constitute a matrix candidate library, which will enhance the reliability of matrix adjustment and selection basis, solidify the matrix use option, and help to promote the stability and smooth operation of BF.
