Title
Pyrometallurgy : Cold Model Study on Burden Falling Flows in Blast Furnace
정진수Jin Su Jung,이상호Sang Ho Yi,정석광Suk Kwang Chung
Abstract
The burden flows by modification of rotating chute were studied using 1/16 scaled model of blast furnace. Adoption of repulsion plate on the marginal end of chute turned out to be very effective to control the falling width of ore and coke. Because falling trajectory of burden moved to central part, tilting angle of chute needed to be decreased to maintain same profile with that of conventional chute. Furthermore the mixed zone of ore to coke and piling of large particle size at the furnace center were increased, which was anticipated to show some positive effects for ensuring central gas flow.
