摘要
采用单因素试验法,研究除尘灰配比对烧结生产过程中原料造粒、料层透气性、烧结矿质量、燃料消耗以及设备利用系数的影响。试验结果表明,除尘灰添加量为2%时,烧结原料中大于3mm的粒级分布达到57.8%,烧结矿落下强度为67.68%,转鼓指数为70.83%,FeO含量为7.13%,成品率为86.88%,燃料消耗为80.8kg/t,设备利用系数为1.93t/(m2.h)。按此配比,能获得原料的造粒、料层透气性、烧结矿质量、燃料消耗以及设备利用系数的较佳效果。
Single factor experiment was carried out to study the effect of proportioning rate of pr tot dust on the granulation, sinter-bed permeability, the sinter quality, fuel consumption and e ey of equipment in course of sintering. The result shows that, when the precipitator dust co 2%, the sintering material with a particle size larger than 3 mm accounts for 57.8%, and the boasts comparatively higher quality with falling strength at 67. 68%, drum index at 70.83% content at 7.13%, and yield at 86.88%. With this mixture ratio, fuel consumption is 80.8 kg/t and equipment utilization factor is 1.93 t/（m2·h）
