由于焦炭、烧结矿和球团矿三种炉料颗粒流出溜槽时速度不同，其在空区内下落轨迹也因此有所差异。在炉料下落过程中，其距高炉中心距离不断增大，且在相同高度处烧结矿距中心距离最近、焦炭次之、球团矿位置最远。

Since the velocity of coke, sinter and pellet particles flowing out of chute is different, their falling trajectories in the empty area are also different. In the process of burden falling, the distance from the center of the blast furnace is increasing, and at the same height, the distance between the sinter and the center is the nearest, followed by the coke and the farthest position of the pellet.
