rotating chute(无钟炉顶部件: While the rotating chute is distributing the contents of one lock-hopper bin, the other can be filled. 当一个闭锁料仓用旋转溜槽布料时，另一个闭锁料仓则可以进行装料。)
distribution chute(无钟炉顶部件: ①When the blast furnace stockline has descended to the desired level, the lower seal valve opens and allows the charge to flow at a controlled rate onto the distribution chute. 当高炉料线下降到预定位置时，下密封阀打开，炉料按可控流速进人布料溜槽。② The distribution chute rotates around the vertical axis of the furnace and changes to predetermined angles with respect to the horizontal plane. 布料溜槽围绕炉子竖轴线旋转，并调整到预定的水平倾角。)
