昆钢6号高炉投产3年来,通过改进喷煤系统,提高喷煤量,加强原燃料、设备和炉前管理,采用双预热技术提高风温,加强冷却系统管理等措施强化高炉冶炼;通过加强炉内操作管理,优化送风制度和装料制度,稳定料速,冶炼低硅生铁等措施优化高炉操作,高炉技术经济指标不断改善,2001年利用系数达2.040,焦比401 kg/t,煤比121 kg/t。 Kunming Iron and Steel 6th blast furnace put into production three years ago, by improving the coal injection system, increase coal injection, and strengthen the management of raw fuel, equipment and furnace, dual preheating technology to improve air temperature and strengthen the cooling system management and other measures to strengthen blast furnace smelting; In order to optimize the operation of the blast furnace, blast furnace technical and economic indicators have been continuously improved. Utilization factor was 2.040, coke ratio 401 kg / t, coke Than 121 kg / t.
