摘　　要：为适应绿色低碳钢铁冶炼目标,球团大型化生产成为必然需求。由于带式焙烧机料层较厚,且焙烧过程球团处于静态,为保证成品球质量,生球的均匀布料就显得尤为重要。本文通过研究带式焙烧机布料原理和布料工艺设备参数,确定其合理的布料方式。研究结果表明:梭车和摆头皮带机布料均存在生球落下次数多、布料不均匀等问题;往复式布料器布料能够减少生球落下次数,且能够实现单向布料,快速换向,从而保证均匀布料。通过参数计算,得出504 m^(2)带式焙烧机合理的布料方式为往复式布料器+宽皮带机布料,卸料小车移动速度和皮带运行速度均应控制在0.65 m/s,宽皮带机运行速度应控制在0.12 m/s。生产实践表明在该布料方式下,布料轨迹整齐,台车料面平整,成品球强度均匀,达到了预期的研究目标。In order to meet the goal of green and low-carbon steel smelting,large-scale pellets production has become an inevitable demand.Due to the thick material layer of the straight grate and the static pellets during the roasting process,in order to ensure the quality of the finished pellets,the uniform distribution of fresh pellets is particularly important.After the distribution principle and distribution process equipment parameters of the straight grate are studied,the reasonable distribution method is determined.The results show that the distribution of the shuttle and the swing head belt conveyor has such problems as numbers of fresh pellets falling and the uneven distribution.The distribution of reciprocating distributor can reduce the number of fresh pellets falling,and can realize one-way distribution and fast reversing,so as to ensure uniform distribution.Through the parameter calculation,it is concluded that the reasonable distribution method of the 504 m^(2) belt roaster is reciprocating distributor+wide belt conveyor distribution,the moving speed of the unloading trolley and the running speed of the belt should be controlled at 0.65 m/s,and the running speed of the wide belt conveyor should be controlled at 0.12 m/s.The production practice shows that under this distribution method,the distribution trajectory is neat,the material surface of the trolley is smooth,and the strength of the finished pellets is uniform,which achieves the expected research goal.
