Abstract：The high powder content of blast furnace raw fuel has a great influence on blast furnace smelting， resulting in the fluctuation of blast furnace condition and chaotic airflow distribution， which is not conducive to the formation of central air flow. Therefore， reducing the powder content into the furnace， making the blast furnace condition normal and easy to operate， is an important measure to ensure the stable operation of the blast furnace and high yield， so as to achieve cost reduction and efficiency， and achieve greater economic benefits.
