摘　　要：为了研究并罐无钟布料器炉料落点,以4150 m^3实际高炉参数为基础,基于炉料运动过程建立模型。通过模型分析得到料流宽度增加1m,则溜槽最大倾角减小2.5°。料线高差增加1m,落点半径增加0.83m。溜槽长度增加1m,落点半径增加0.83m。通过与1∶1布料实验数据作对比,得到平均误差百分比为2.93%,验证了模型的准确性,为优化布料设计提供理论依据。In order to study the burden falling point of the two parallel hoppers with bell - less top,based on the bell - free top of 4150m3 blast furnace,a mathematical model was built to analyse theburden movement process. The distribution of the falling point is researched,with increasing the bur-den width by 1m, the chute maximum angle is reduced by 2. 50. With indistance by 1m,the drop radius is increased by 0. 83m. With increasing the length of chute by 1m,the drop radius is increased by 0. 83m. By comparing the experimental data with 1： 1 burden distribu-tion process, the average error percentage is 2. 93% , which verifies the accuracy of the model and pro-vides the theoretical basis for optimizing the fabric design.
