摘要 为研究昆钢目前使用的3种粉矿的成矿性能,针对其原料特点设计正交试验方案,进行大量系统的烧结杯试验。通过试验数据分析,得到每种矿混合料平均粒度以及烧结矿转鼓强度表达式。利用单因素分析法和极差法研究了配碳量和碱度对烧结矿FeO、转鼓强度、成品率以及利用系数的影响。试验结果得到每种矿的最佳配碳量和碱度配比。分析发现,配碳量对3种矿烧结指标的影响大于碱度的影响。 According to its raw materials,orthogonal test scheme was designed and a large number of systemic experiments were carried out in order to study the sintering characteristics of three types of fine ores in Kunming Iron and Steel Co.,Ltd.(KISC).Expressions of mineral mixture average particle size and sintering tumble strength were obtained by analyzing the experimental data.The effects of carbon mixture ratio and basicity on FeO of sintering ore,agglomeration ratio,tumble strength and utilize coefficient were researched via single factor analysis and range analysis.The best mixture ratio of each fine ore were obtained from the experimental results.Analysis found that the influence of the carbon mixture ratio is more significant than which of the basicity on the sintering process except agglomeration ratio of foreign ore.
