Abstract

Based on the movement analysis of burden in charging, a mathematical model of bell-less burden distribution is established to study the burden distribution in the furnace. The mathematical model consists of three sub-models: the material trajectory model, burden profile model, and burden descent model. The novel fitting formula that chute inclination angle and ratio of mixed ore affect the inner angle and outer angle of repose is proposed. The influence of pellet and sinter shapes on the inner angle and outer angle of repose of the ore is considered by introducing a correction coefficient. The modified fitting relation is applied to the mathematical model for bell-less blast furnace to analyze the influence of the proportion of pellet on the surface shape and radial distribution of ore–coke ratio under the same burden matrix. The influence rule of mixed ore ratio on burden distribution is obtained, which provides basis for adjusting the upper part of blast furnace.
