1 引言 攀钢3号高炉第二代炉役于1994年4月停炉大修,第三代炉役于同年6月投产。由于炉衬砌筑质量和冷却设备质量差,加上布料设备使煤气流分布偏析,导致高炉炉衬不均匀蚀损,只生产3.5年时间,炉衬局部严重破损,炉腹至炉腰的炉壳转折点处局部变形、开裂,严重危及高炉正常生产。于是,在1998
1 Introduction Panzhihua Iron and Steel No. 3 blast furnace second-generation furnace in April 1994 shutdown overhaul, the third generation of furnaces commissioned in June the same year. Due to the poor quality of the lining of the lining and the quality of the cooling equipment and the distribution of the gas flow caused by the distribution of the cloth equipment, uneven erosion of the lining of the blast furnace resulted in only 3.5 years of production, serious localized damage to the lining, Local deformation, cracking, seriously endangering the normal production of the blast furnace. So, in 1998
