This paper presents theoretical analysis of microstructure changes in the material during standard rolling and normalizing rolling of the 35×20 mm flat bars. The analysis was carried out by means of computer software Forge 2007～R that is based on finite element method. Two cases of accelerated cooling during rolling process were considered. Numerical results of 35×20 mm flat bars rolling process allowed to determine the average recrystallized austenite diameter as well as basis energy and force parameters. Proposed modification of the 35×20 mm flat bar rolling technology with accelerated cooling results in the reduction of average austenite diameter, which could improve the strength of the final product.
