针对并罐式无钟炉顶的布料操作易产生蛇形偏料,形成不均匀的料面形状,导致料面透气性调节失控的问题,引入颗粒物质能量耗散系数计算方法,探讨颗粒蛇形下落的速度方向对颗粒在溜槽内的有效运动长度和溜槽出口处颗粒速度的影响.分析了并罐式炉顶布料产生炉喉料流轨迹落点差异,料面厚度不均匀的蛇形偏料原因.结果表明,料流密集点在溜槽上形成的碰撞轨迹并非是标准椭圆形状,而是两个不同长轴的半椭圆相接形成的碰撞轨迹,大椭圆的短轴等于小椭圆的长轴.
Aiming at the problem that the material handling of the bell-shaped bell-less top is easy to produce serpentine partial material, forming uneven material surface shape, resulting in uncontrollable air permeability adjustment of the material surface, the energy dissipation coefficient calculation method of particulate matter is introduced, The effect of falling velocity on the effective movement length of particles in the chute and the particle velocity at the exit of the chute was analyzed.Analyzed the differences between the trajectories of the furnace ladle flow path and the snake- The results show that the collision trajectory formed on the chute by the dense point of the flow is not the standard elliptical shape but the collision trajectory formed by the semiellipses of two different major axes with the minor axis of the major ellipse equal to the major axis of the minor ellipse .
