摘要
利用微型烧结实验装置及烧结杯试验,对鞍钢铁矿粉的同化特性、液相固结强度、液相流动性及连晶能力等烧结特性进行综合评价.在此基础上,提出了烧结合理配矿原则,并应用到生产实践.研究结果表明,鞍钢烧结生产应以精矿B,D搭配精矿C为主,球团生产应以精矿A为主.配矿优化调整后,炼铁技术经济指标明显改善,高炉利用系数提高了0.043 t/(m3.d),入炉焦比降低了5.28 kg/t,烧结矿成本降低2.2元/t.
The basic sintering properties of iron ores were investigated experimentally by miniature sintering setup and pot, and evaluated comprehensively, such as assimilability of iron concentrates, strength of liquid consolidation, fluidity of liquid phase, capability of crystal stock. Then, a rule of reasonable batehing by weight for sintering was found and applied to practical production. The results showed that in the sintering process the hatching mainly depends on the concentrates B and D mixed with C, while in the pelletizing process the concentrate A is principal in ANSTEEL. The ironmaking technical-economic indices are thus improved obviously after optimizing and readjusting the hatching, e.g. , the BF utilization coefficient increases by 0.043 （t/m^3·d）, and the coke ratio decreases by 5.28 kg/t with sinter cost being reduced by 2.2￥/t.
