Abstract：In the past 40 years, Chinese iron and steel industry has made great progress, the crude steel production output has ranked first in the world for many years. Chinese blast furnace ironmaking technological equipments have achieved outstanding achievements in large-scale, modernization, high-efficiency, long service life and so on. Since 2000, a batch of super large blast furnaces above 5000m3, large sintering machines above 500m2, large volume coke ovens with battery height 7.0 m and large pelletizing production lines with an annual output of 4 million t/a have been built and put into commissioning in succession, and a series of the key technologies of integrated innovation and independent research have been achieved great achievements in production practice. At the same time of the technical equipments large sizing, a lots of advanced technologies and equipments research and application have been achieved remarkable results, such as blast oxygen enrichment and pulverized coal injection, bell-less top equipment, BF gas dry dust removal, dome combustion hot blast stove and high blast temperature technology, high efficiency and low consumption sintering technology, large scale clean coking technology, and so on. These achievements promote the progress of ironmaking technologies and equipments. Up to the middle of this century, great changes will take place in the situation and steel manufacturing process structure of China’s iron and steel industry. Reduction, greennization, intelligentization and high efficiency will be the main development tendency of ironmaking technology and equipment in the coming period.
