Abstract

In Japan, blast furnace operating is currently aiming at low reducing agent to decrease carbon dioxide emission from steel works. Moreover, the inner volume of the blast furnace has been frequently enlarged over 5000m3 at the relining. In such a condition, discontinuous and instable phenomena in furnace have been actualized. The precise control of blast furnace operation is required to attain the smooth operation. Numerical simulation is the effective method which helps to understand the in-furnace phenomena directly. In this paper, analysis of solid motion in the total blast furnace model carried out by discrete element method (DEM). The mechanism of various discontinuous phenomena can be simulated by this model on the basis of the physical parameters optimized for blast furnace.
