We describe the results for full-scale experimental test production of high-basicity sinter (basicity 2.0–5.0) at the Enakievo Metallurgical Plant Sinter Shop. As sinter basicity increased from 2.0 to 5.0, the iron content of the sinter decreased from 53.05% to 32.24%, and the ferrous oxide concentration decreased from 17.55% to 9.29%. However, the strength specifications of the sinter were improved: The concentration of 0–5-mm fines decreased from 19.32% to 15.89%, and the yield of +5 mm size class in a drum test increased from 65.9% to 72.3% through optimization of the sintering process parameters. The use of high basicity sinter in blast-furnace smelting reduced the specific consumption of lime in the blast-furnace charge from 233.9 kg/metric ton of cast iron (at sinter basicity 2.0) to 103.5 kg/metric ton (at basicity 4.5) and, correspondingly, the specific feed rate for coke during castiron production decreased from 538.1 kg/metric ton to 476.6 kg/metric ton.

Enakievo冶金厂烧结车间高碱度烧结矿全尺寸试验生产

我们描述了在 Enakievo 冶金厂烧结车间对高碱度烧结矿（碱度 2.0-5.0）进行全面实验测试生产的结果。随着烧结矿碱度从2.0提高到5.0，烧结矿铁含量从53.05%下降到32.24%，氧化亚铁浓度从17.55%下降到9.29%。然而，烧结矿的强度指标有所提高：通过优化，0-5mm细粉的浓度从19.32%下降到15.89%，转鼓试验中+5mm级的产量从65.9%提高到72.3%烧结工艺参数。在高炉冶炼中使用高碱度烧结矿将高炉炉料中的石灰比消耗量从 233.9 公斤/公吨铸铁（烧结矿碱度 2.0）降低到 103.5 公斤/公吨（碱度 4.5）和，相应地，
