焦粉在烧结过程中作为燃料添加。焦粉的粒度分布是重要因素之一，对于实现适当的烧结过程起着重要作用。因此，研究了焦粉粒度分布对烧结性能的影响。实验结果表明，在实际生产中，应根据不同的生产策略（以最佳强度或最高生产率为目标，或其他）调整焦粉的粒度分布。例如，以最大滚转强度为目标的烧结矿，焦粉的粒度分布应为-1mm的57.20%、1~3mm的25.63%、3~5mm的11.17%和+5mm的6.00%。则烧结矿的滚转强度提高约1.48%，产量提高约1.7%。同样，为了获得最大生产率的烧结矿，焦粉的粒度分布应为-1mm的47.22%、1-3mm的23.10%、3-5mm的28.68%和+5mm的1.00%。在这种情况下，生产率提高了0.1 t m−2 h−1，烧结速度提高了0.7 mm min−1，成品率提高了0.4%。烧结矿B（通过最大滚滚强度优化）具有更好的烧结性能有两个原因，它们如下：（i）焦粉尺寸对烧结温度曲线的影响和（ii）孔隙分布。本工作的研究成果可为实际烧结过程中合理利用燃料资源提供科学指导。
Coke breeze is added as fuel in sintering process. The size distribution of coke breeze is one of the important factors, which plays an important role in achieving proper sintering process. Therefore, the effects of size distribution of coke breeze on sintering performance are investigated. Experimental results show that, in practical production, we should adjust the size distribution of coke breeze according to the different production strategy (aimed for best strength or highest productivity, or others). For example, aimed for sinter with maximum tumble strength, the size distribution of coke breeze should be 57.20% of −1 mm, 25.63% of 1–3 mm, 11.17% of 3–5 mm, and 6.00% of +5 mm. Then the tumble strength of sinter increases about 1.48%, production yield increases about 1.7%. Similarly, aimed for sinter with maximum productivity, the size distribution of coke breeze should be 47.22% of −1 mm, 23.10% of 1–3 mm, 28.68% of 3–5 mm, and 1.00% of +5 mm. For this case, the productivity increases 0.1 t m−2 h−1, the sintering speed increases 0.7 mm min−1, and the production yield increases 0.4%. There are two reasons for that sinter B (optimized by maximum tumble strength) has better sintering performances, they are as follows: (i) the effect of coke breeze size on the sintering temperature profile and (ii) pores distribution. The research results of present work could give a scientific guide to reasonably utilize fuel resources in practical sintering process.
