Abstract Accurate evaluations of the burden distribution are of critical importance to stabilize the operation of blast furnace. The mathematical model and discrete element method (DEM) are two attractive methods for predicting burden distribution. Based on DEM, the initial velocities of the pellet, sinter, and coke were calculated, and the velocity attenuations of the above three particles between the burden and the chute were analyzed. The initial velocity and velocity attenuation were applied to a mathematical model for improving the accuracy. Additionally, based on the improved model, a scheme for rectifying the chute angles was proposed to address the fluctuation of the stock line and maintain a stable burden distribution. The validity of the scheme was confirmed via a stable burden distribution under different stock lines. The mathematical model has been successfully applied to evaluate the online burden distribution and cope with the fluctuation of the stock line.
