Influence of Semicharcoal Substituted for Coke Breeze on Sintering Performance

摘要: 通过不同燃料结构条件下的烧结杯试验,探究了应用兰炭作为烧结燃料对烧结过程的影响。试验结果表明:不同燃料结构条件下,兰炭替代焦粉的适宜比例有所差异。在燃料比为4.6%条件下,兰炭替代焦粉比例能够达到20%,此时烧结产量较高,且烧结矿具有较好的冶金性能;当燃料比为5.2%时,兰炭替代比例可进一步提高到40%。在保证烧结矿产量和质量的前提下,烧结过程中配加兰炭对降低烧结矿成本具有积极的作用。Abstract: The pot grate sintering tests were carried out with the variation of sintering fuel structure and the effect of semicharcoal substituting for coke breeze on sintering performance was investigated. The experimental result showed that the proper substitution ratio of semicharcoal for coke breeze varied with the sintering fuel structure. As the sintering fuel ratio was 4.6%,semicharcoal substitution ratio reached 20% and sinter had better performance. When fuel ratio was 5.2%,the proper substitution ratio of semicharcoal could be increased to 40%. On the circumstance that sinter performance was guaranteed,the utilization of semicharcoal as sintering fuel was an effective method to decrease sinter cost.
