| 摘 要： | 某微细粒嵌布高磷鲕状赤铁矿TFe品位44.56%,利用自制的实验室间歇式悬浮焙烧炉,考察了给矿细度、气流速度、H2浓度、焙烧温度、焙烧时间等对悬浮焙烧的影响,在适宜的条件下,获得了TFe品位56.73%,回收率83.96%的最优指标。相比于马弗炉焙烧,悬浮焙烧可以缩短焙烧时间,提高焙烧产品质量,降低焙烧能耗,具有较强的推广意义。

| Abstract: | The fine-disseminated high phosphorus oolitic hematite with a TFe grade of 44.56% was researched by the homemade laboratory batch-type suspension roaster. The feeding fineness, gas velocity, hydrogen concentration, roasting temperature,roasting time were investigated and at an appropriate condition, the optimal index with a TFe grade of 56.73% and a recovery of 83.96% was achieved. Compared with a muffle furnace, the suspension roaster can shorten roasting time, improve product quality and reduce roasting energy consumption with a high popularizing significance. |
