摘　　要：针对1#350m3高炉已进入炉役后期、设备老化和各种不确定因素增加的现状,通过采用富氧鼓风与风机并联、高风温和"提碱控硅加酸洗"操作法、炉缸表面埋设电偶等炉内操作技术,采取加强设备管理、炉前和上料的操作与管理等措施,确保了高炉的稳定顺行,优化了各项技术经济指标,利用系数达到3.565m3/(t.d),焦比、煤比分别达到399kg/t、136kg/t。Pointing to present status of No.1 350m\+3 BF, passing into later stage of campaign and equipments ageing and increasing of various uncertainty, some active operation and management measures included adopting rich oxygen blasting and parallel connection fan, adopting high wind temperature and operating way of 'increasing basicity and controlling Si', setting up thermoelectric couple on the surface of furnace crucible, strengthening equipment management and charging operation, etc, have been applied. These methods ensured the stabilizing and smoothing of BF operation, the utilization coefficient of BF is up to 3.565m\+3/(t.d), the coke rate and coal rate are up to 399kg/t and 136kg/t respectively.
