摘要
燃料比是高炉炼铁生产的主要经济技术指标,降低高炉燃料比对企业节能减排意义重大。文章分析了包钢6号高炉燃料比高的原因,在6号高炉大修开炉后,通过原燃料提产攻关稳定高炉供料、改善原燃料质量、高炉操作严格控制压差、调整装料制度、稳定高风温、合理使用富氧和喷煤、加强基础管理等措施的实施,高炉燃料比降低,2021年累计燃料比为545.84 kg/t,较2020年降低10.58 kg/t。
The fuel ratio is the main economic and technical index for blast furnace ironmaking,so it is of great significance for energy conservation and emission reduction of enterprise to reduce it.In this paper,the reasons for high fuel ratio of 6#blast furnace of Baotou Steel are analyzed.After the overhaul and blow-in of 6#blast furnace,the fuel ratio of blast furnace is reduced through taking such measures as tackling key problems in improving production to stabilize the feed of blast furnace,improving quality of raw fuel,strictly controlling differential pressure in blast furnace operation,adjusting charging system,stabilizing high blast temperature,reasonable use of enriched oxygen and coal injection as well as strengthening basic management.The cumulative fuel ratio in 2021 was 545.84 kg/t,which was 10.58 kg/t lower than that in 2020.
