Numerical simulation analysis of pressing and forming process of refractory brick

The displacement of the powder in the forming direction and the relative density distribution of the forming green were studied by MSC. MARC finite element simulation software. Refer to relevant industry literature, the influence of different template friction coefficient, pressing method and pressing height diameter ratio on the displacement and relative density distribution of powder was studied. In addition, the change of powder body in the pressing process of cylindrical shaped refractory brick with convex and groove is also under preliminarily study. The results show that the friction of the die wall leads to the retardation of the lateral displacement and the relative density distribution of the refractory brick. The uniformity and compactness of the brick can be improved by reducing the friction coefficient of the template surface and the height-diameter ratio of the brick. The numerical simulation process of pressing cylindrical refractories with convex and grooves still needs to be further studied.
