本钢2850m~3高炉降低焦比的生产实践

对本钢7号高炉降低焦比的实践经验进行了总结。认为原燃料条件的改善、合理的炉型、优化布料矩阵及大批重、合理的送风制度、高风温、高富氧,以及各项制度的合理匹配是本钢7号高炉降低焦比的主要经验。由于7号高炉率先使用大批重煤气利用率好,炉况稳定顺行,焦比降低,煤比提高,各项技术经济指标达到国内3000m3级高炉先进水平。

Benxi Iron and Steel 2850m~3 Blast Furnace Coke Production PracticeReduces

Benxi Iron and VII of the practical experience of blast furnace coke rate reduction are summarized.That the original fuel conditions improve,a reasonable furnace,optimizing weight distribution matrix and a large quantity,reasonable air supply system,high air temperature,high oxygen,and a reasonable match of the system is reduced coke rate Benxi VII BF Main experience.As the first to use a large number of heavy blast VII gas utilization is good,FURNACE CONDITION lines,reducing coke,coal ratio increases,the t...
