摘　　要：首钢京唐公司基于自身配矿结构特点和降本增效的实际需求,烧结尝试大比例使用高性价比但SiO_(2)、Al_(2)O_(3)含量较高的3种新矿粉。通过开展研究铁矿粉同化性、液相流动性等基础性能以及烧结杯实验,分析了新矿粉配加后对烧结技术经济指标的影响,并根据研究结果进行了替代主流矿粉的生产应用。实践表明,3种矿粉在混匀矿中总质量占比提高至20%以上替代主流矿粉是可行的。同时,结合京唐烧结工艺控制,实现了烧结矿质量整体稳定,配矿成本降低,铁水原料费用可降低约4元/t。Based on the specific characteristics of its ore blending structure and the need to reduce costs and increase efficiency,Shougang Jingtang Company conducted sintering experiments using three new types of ore powders that offer high cost-effectiveness but have relatively higher SiO_(2) and Al_(2)O_(3) content.This paper presents a study on the assimilation behavior,liquid-phase fluidity,and sintering cup experiments of the new ore powders.It analyzes the impact of incorporating these new ore powders on the economic indicators of the sintering process and applies the research findings to replace mainstream ore powders in production.The results show that increasing the total proportion of the three new ore powders to over 20% in the blended ore mixture as a feasible alternative to mainstream ore powders.By combining this approach with the control of the Jingtang sintering process,the overall stability of sinter quality was achieved,resulting in reduced ore blending costs and a decrease of approximately 4 RMB/ton in iron raw material expenses.
