In blast furnaces, the chute is the key device determining burden distribution. The effects of the chute's geometric and operational parameters on burden distribution have seldom been studied. Herein, the top of a bell‐less blast furnace is modeled based on the discrete element method to investigate the effects of chute length, stock‐line level and chute angle on particle movement, and radial burden distribution. The results indicate that burden particles are more likely to slide toward the opposite to the rotating direction as the chute length or angle increases. The burden distribution segregation is mainly caused by the segregation of particle velocity on the chute and the percolation of pellet on the chute. The burden tends to aggregate with increases in chute length and disperse with increases in stock‐line level or chute angle.

基于离散元法的无贝尔高炉操作参数对颗粒运动和分布的影响

在高炉中，溜槽是确定负荷分布的关键设备。很少研究溜槽的几何参数和运行参数对负荷分布的影响。在此，基于离散元方法对无罩高炉的顶部进行建模，以研究斜槽长度，料线高度和斜槽角度对颗粒运动和径向负荷分布的影响。结果表明，随着溜槽长度或角度的增加，装料颗粒更有可能朝与旋转方向相反的方向滑动。负荷分布偏析主要是由颗粒速度在溜槽上的偏析和颗粒在溜槽上的渗滤所引起的。负担倾向于随着滑道长度的增加而聚集，而随着库存线水平或滑道角度的增加而分散。
