摘　　要：高炉溜槽作为无钟炉顶装料设备的重要组成部分,其参数变化对布料操作有很大影响。比较常见的2种溜槽截面形状是半圆形溜槽和矩形溜槽。由于截面形状不同,颗粒在溜槽内的运动过程会发生变化。目前关于矩形溜槽布料过程的数学模型研究较少。通过分析颗粒在2种不同截面溜槽内的运动过程,研究截面形状变化对料流轨迹的影响,并将计算结果与模型试验测试结果进行对比。研究结果可为实际高炉溜槽截面形状的选择及不同溜槽布料操作提供理论指导。As one of the important parts of the bell-less top, the parameters of the chute have great influence of the burden distribution. There are two kinds of chute used commonly, one is a semicircle and the other is a rectangle. Because of the different cross section shape, the movement of the particles in the chute was changed. At present there is less mathematical model about the burden distribution for rectangle chute. Trough analyzing the particles moved in the two kinds of chute, the influence of the chute cross section shape on the particle movement was discussed. The calculated result was compared with the experimental result. The results can guidance the chute cross section choose and the blast operation.
