Abstract： The solid flow in 5000m3 blast furnace was simulated by 3Ddiscrete element method under the condition of different Young’s modulus. It is found that when Young’s modulus is 0.06GPa, the magnitude of particle deformation is greater than the half of the radius of particle. Moreover, the burdens in shaft are mixed and cokes in hearth are stacked along the wall, which result in the decrease of free space. After 100 time steps, the calculation would terminate naturally. When Young’s modulus is in the range of 10GPa and 0.6GPa, the angle of layer in shaft would increase with the decrease in the Young’s modulus. In the lower part of blast furnace, the transition zone of velocity between melting zone and deadman would decrease, and the height of deadman increase, however, the normal and shear stress between particles would increase with the decrease of the Young’s modulus. In addition, the decrease of Young’s modulus results in the decrease of the relative slip behavior between particles. But, the variation of Young’s modulus would not change the characteristics of motion of burden in blast furnace that is composed of the steady motion and the transient motion of burden.
