柳钢2号高炉(318m~3)为无框架、无支柱自立式高炉,已运行4年2个月,于1989年2月10日发现该炉西南方位(重力除尘器侧)炉喉钢砖下沿出现上部宽9m,深约3.5m达16m~2左右的塌砖面积,为确保高炉安全和继续生产,并借此积极准备检修条件,柳钢在进行试验研究的基础上,于1989年3月至11月对该高炉炉身上部塌砖区采用灌浆造衬护炉,使其继续生产了8个月。这一新工艺不仅为中修准备工作赢得了充分的时
Liuzhou No.2 blast furnace (318m ~ 3) is a frameless, non-pillar free-standing blast furnace which has been in operation for 4 years and 2 months. On February 10, 1989, it was found that the stove southwest azimuth In the lower edge of the emergence of the upper width of 9m, about 3.5m depth of about 16m ~ 2 of the collapse of brick area, in order to ensure the safety of the blast furnace and continue to produce, and to take active preparations for maintenance conditions, based on the experimental study of Liuzhou Steel in 1989 From March to November, the lining of the blast furnace in the upper part of the blast furnace was used to make a liner lining furnace to continue the production for 8 months. This new craft has not only won sufficient time for the preparatory work in repair
