A major term of highly productive functioning of rolling mill is a good realized roll pas design which allows to get a finished profile according to required dimensions, surface roughness and uniform mechanical properties on length and width of billet; to implement rolling with the least disbursement of rollers and energy as well as minimal rolling time; to eliminate manual labor and make the rolling process automated and mechanized as much as possible. When selected the approach of forming process simulation it’s necessary to take into account the specific character of concerned problem. This allows minimizing the account time and computer resource by using some specific mathematic simplifications. So-called 2.5D method allows using several hypotheses to achieve the frequentative reduction of account time and at the same time to avoid critical sacrifice of accuracy. The paper dials with comparison of 3D and 2.5D finite element simulation principles by the example of modeling of round shape billet rolling. The results of simulation using both methods are presented. The fields of deformations and temperature as well as calculated geometric parameters of the billet and assessment of error are considered.
