A three-dimensional, thermo-elasto-plastic finite element stress model with temperature-dependent thermal-physical mechanical properties, to compute the thermo-mechanical state of the solidifying shell and the distortion of mould during continuous casting of steel for a round billet has been developed to investigate the influence of mould friction on the strand stress. A method is applied to prevent penetration of the shell into the mold wall due to the ferrostatic pressure and excessive mould taper. Slag film thickness, air gap size and the contact state between the shell and mould have been predicted based on shell shrinkage and mould distortion including the mould taper, associated with their temperature fields. Ultimately, the influence of mould friction on the strand stress was also investigated. And the calculation results show that the magnitudes of the influence of mould friction on strand stress vary with various contact states, such as liquid slag film, direct contact, and air gap, between the shell and mould from one location to another.
