唐钢高炉喷吹煤粉配加碳粉的生产实践

摘要

对唐钢高炉喷吹煤粉中配加碳粉进行生产实践研究，研究表明喷吹煤粉中配加5%碳粉能够满足高炉喷吹条件，并且使混煤成本降低6．2元/t。根据高炉日常生产数据的比较分析，喷吹碳粉以后高炉能够稳定顺行，未对高炉日常生产造成不良的影响。%The production practice of the coal injection with addition of carbon powder on Tangsteel blast furnace was researched, the research indicated that coal injection with addition of 5% of the car-bon powder can meet the injection in the blast furnace conditions, and lower the mixed coal cost 6. 2 yuan/t. According to the daily production data of comparative analysis of blast furnace, carbon powder injection after the blast furnace can stabilize anterograde, without adverse effects on the daily produc-tion of blast furnace.
