Resumo
Shougang Jingtang iron and steel plant engineering is an important project of China iron and steel industry structure adjustment and improvement of general technology and equipment level. Its annual output is 9.7 Mt/a, including two sets of 5,500 m3 blast furnace with annual hot metal output of 8.98 Mt/a. A number of innovative advanced technologies including bell-less top, dome combustion hot blast stove, blast furnace gas dry bag filter cleaning process and environmental protection screw slag granulation facility etc. are developed. In this paper description is given to the technical features and advanced technologies of the extra large sized blast furnace in Shougang Jingtang. Also introduction is made to blast furnace sinter charging by different fraction sizes, bell-less top equipment and control technology of burden distribution, high efficiency and long campaign life technology of blast furnace, high blast temperature with long campaign life technology of dome combustion hot blast stove, environment-friendly slag treatment technology, oxygen-enrichment pulverized coal injection technology and blast furnace gas dry type bag filter cleaning technology that are applied to the 5,500 m3 blast furnace at Shougang Jingtang.
