在考虑溜槽旋转和倾动对炉料运动影响的基础上,分析了炉料在溜槽上和空区中的运动,推导出炉料在料面上的落点半径规律,并结合螺旋布料定义,得出了螺旋布料时溜槽倾角变化规律必须满足的方程。通过数值方法求解并绘制了炉料在料面上的落点轨迹。与环形布料相比,结果表明采用螺旋布料可以获得更加均匀的料面。 Based on the influence of the rotation and tilting of the chute on the charge movement, the movement of the charge in the chute and the empty area was analyzed, and the law of falling radius of the charge on the material surface was deduced. Based on the definition of the spiral fabric, the spiral When the fabric chute inclination changes must meet the equation. Through the numerical method to solve and draw the charge on the material surface of the landing trajectory. Compared with the ring-shaped fabric, the results show that the use of spiral fabric can be more uniform material surface.
