Abstract：

Based on stress status of incomplete spherical joints during slab side pressing for sizing press mill, the contact finite element model was established by non-linear finite element contact theory. The maximal testing rolling force was taken as force boundary condition of the finite element model. It can obtain the stress peaks and its location through calculating the distribution of stress field. The results show that peak value of contact stress is 89.68 MPa and within the scope of safety. The research results can provide reference for understanding the working state of incomplete spherical joints and exploiting the equipment potential for site staff.
