抄録

Experiment was conducted with a 45°segment full-scale model to investigate the burden distribution in direct reduction shaft furnaces equipped with the charging pipe. The findings are as follows :<BR>1) The charged material moves from the charging pipe first in a pushing flow like a landslide and then in a rolling flow toward the wall.<BR>2) Size segregation occurs in the rolling flow through a percolation process, while less segregation in the pushing flow.<BR>3) The size distribution can be expressed as relative distance of charged material movement irrespective of throat diameter.<BR>4) High content of fine particle in lump ore layer remarkably increases the gas permeability resistance around the charging pipe.
