Abstract: To clarify the influence of friction coefficient and molding pressure on the pulverized coal molding process, the MSC. Marc software was used to quantitatively analyze the characteristics of heterogeneous change of pulverized coal in the molding process, and the distribution parameters in the molding process were obtained, such as stress, density and displacement. The results show that with the increase of friction coefficient, the maximum displacement gradually decreases, the uniformity of relative density decreases, and the maximum stress increases sharply from 6.013 MPa to 71.22 MPa , which easily causes the cracking of the briquette. Moreover, with the increase of forming pressure, the maximum displacement continues to increase, and the relative density slightly increasea, while the maximum stress shows a sharp increasing trend. Therefore, the friction coefficient should be appropriately reduced and the molding pressure should not be blindly increased during the pulverized coal molding process.
