Abstract

A mathematical model is proposed for assessing the gas permeability of the cohesive zone in the blast furnace. The gas permeability is improved by increasing the intensity of the axial gas flux and introducing coke nuts in the ore layer. This is important in introducing intense pulverized-coal injection.
