Abstract

Abstract

Gas volume through the sinter bed is one of the very important factors that determine the productivity of sintering. When the capacity of the exhaust fan is fixed, the increase of gas volume through the sinter bed can be only realized by the reduction of sinter bed resistance to airflow. On laboratorial conditions, the effect of bed permeability improvement under the condition of standsupport sintering was studied, and the productivity, drum index, product yield and size composition were investigated quantitatively. The results showed that applying stand-support during sintering, the productivity increased by maximum 23.15% and the drum index decreased slightly, while it still met the demand of ironmaking. The metallurgical properties of sinter were improved at the meantime.
