本文应用经典力学原理,结合散体力学知识,全面分析了炉料在无钟炉顶设备中的运动。当炉料在圆形滑槽、旋转溜槽内运动时,在其当量摩擦系数μ_α及质心位置均发生变化的条件下,建立了炉料运动的数学模型,实验测定结果证明了它的适用性,从而在理论上对料流变宽问题进行了初步的考察,并讨论了各操作参数对炉料运动轨迹的影响。 In this paper, the principle of classical mechanics is combined with the knowledge of bulk mechanics to comprehensively analyze the movement of charge in the bellless top equipment. When the charge moves in the circular chute and the rotating chute, the mathematical model of the charge movement is established under the condition that the equivalent friction coefficient μ_α and the position of the center of mass change. The experimental results prove its applicability, In theory, the issue of broadening the flow rate was investigated. The influence of each operating parameter on the movement trajectory of the charge was also discussed.
