临汾钢铁公司炼铁分厂自己设计改造100m~3高炉扩建成220m~3高炉,设计施工共用17个月时间,于1984年10月23日建成投产。设计主要内容:原拟在100m~3高炉的基础上利用已有670m~3/min、风压0.1MPa(1.0kg/cm~2)的风机和库存两套255m~3高炉的设备,扩建成220m~3高炉。实际上,原高炉基础因地耐力降低,而负荷加大,采取在原地基中心相偏移14米处新建高炉基础。热风炉基础则因开挖时,发现基础有横向断裂及基础混凝土变为紫红色,采用打桩加强。利用原有烟囱以增大助燃风机压力来 Linfen Iron and Steel Company ironmaking branch own design transformation of 100m ~ 3 blast furnace expanded into 220m ~ 3 blast furnace, design and construction share 17 months, on October 23, 1984 completed and put into production. The main contents of the design: It is proposed to utilize the existing wind turbines of 670m ~ 3 / min, wind pressure 0.1MPa (1.0kg / cm ~ 2) and two sets of 255m ~ 3 blast furnace equipment on the basis of 100m ~ 220m ~ 3 blast furnace. In fact, the original blast furnace base due to lower endurance, while the load increases, to take the original center of the base phase shift of 14 meters at the new blast furnace foundation. The foundation of the hot blast stove was found digging and found that the foundation had horizontal rupture and the foundation concrete turned mauve and the piling was strengthened. Use of existing chimney to increase combustion air pressure
