Large-scale BF is the tendency of domestic and foreign Iron-making technology.Due to the limit of resource,technology and equipment,we can not reach the planned goal after putting the big BF into production,it is of great significance to explore the key technologies again for the sound development of the large-scale BF.The paper highlights the unique advantages of large-scale BF and the practical performance of BFs in Baosteel,and explores the related parameter choice,comprehensively matched longevity technology optimization and tapping-stability improvement in terms of structure-design,longevity and equipments etc.The author stresses BF centered basic working regulation,hoping it can exert positive effect on the scientific development of large scale BF in China.
