马钢2号高炉低燃料比生产实践

Productive Practice of No. 2 Blast Furance at Low Fuel Ratio in Ma Steel

马钢2号高炉自2003年投产以后,通过加强原燃料管理,确保精料入炉,加强炉体冷却设备管理,控制破损冷却设备不往炉内漏水,不断摸索调整高炉操作制度,维持高炉合理煤气分布,促进高炉降低燃料比,2011年2号高炉在稳定顺行的基础上燃料比进一步下降至485 kg/t.Fe,实现了低燃料比生产。

Since No. 2 blast furnace （hereafter called as ＂BF＂ for short） was put into produc- tion in 2003, we have intensified management of raw material and fuels and ensured concentrated feeds fed to BF. Also, Strengthen the furnace body cooling equipment management, control the damage to the furnace Water Leakage cooling equipment, trial and error adjustment of the operation system of the furnace, to maintain a reasonable distribution of blast furnace blast furnace gas, promote the decrea- sing fuel ratio, No. 2 blast furnace in 2011 based on the stable operation of the fuel is further reduced to 485kg/t. Fe, to realize the low fuel production.
