摘要

烧结台车料层纵向的粒度分布是影响烧结矿质量的重要因素,而九辊布料对烧结台车上的料层分布起着至关重要的作用。为了研究不同条件下九辊布料的效果,根据某钢铁企业烧结机九辊的实际尺寸建立了三维模型,使用EDEM软件对不同工况的布料过程进行了仿真模拟。结果表明,九辊转速从4 增至40 r/min,料层厚度不变,颗粒的堆积角从55°左右减小至49°左右,料层纵向偏析度先增大后减小,当九辊转速为30 r/min时,料层偏析度最高;当九辊排列的倾斜角度从33°增至43°时,料层高度逐渐降低,料层纵向偏析度先增大后减小,当九辊倾斜角为38°时,料层偏析度最高。

Abstract

The longitudinal particle size segregation of the sinter bed is an important factor affecting the sinter quality, and the nine-roller plays a crucial role in the distribution of the material layer on the sintering pallet. Based on the actual size of the sintering nine-roller in a steel enterprise, a three-dimensional model was established, and the distributing process under different conditions was simulated by EDEM soft ware. The results showed that when the nine roller speed increased from 4 to 40 r/min, the thickness of the material layer had no obvious change, and the accumulation angle of particles decreased from about 55° to about 49°, and the longitudinal segregation degree of the material layer increased first and then decreased. When the rotational speed of the nine-roller was 30 r/min, the longitudinal size segregation degree was the highest. When the angle of the nine roller arrangement increased from 33° to 43°, the height of the material layer decreased gradually, and the longitudinal size segregation increased first and then decreased. When the tilt angle of the nine-roller was 38°, the segregation degree was the highest.
