In order to ensure sustainable development of rolling production, technological processes were investigated using computer simulation, which allows us to examine a large amount of information regarding modes of reduction and energy consumption of metal treatment under pressure in order to determine rational values. Simulation of hot rolling process using DEFORM-3D software was performed to investigate energy parameters of treatment and to determine rational reduction modes. During investigation, objects were located in space, exact positioning of casting rollers respectively to workpiece was performed, and rheological model of deformable material was specified, where rigid-plastic environment was adopted. Mechanical properties of workpiece material were determined, low carbon steel was selected as material, reduction between casting rollers was specified, and friction coefficient between workpiece and rollers, which is equal to 0.3; contact interaction between casting rollers and workpiece was specified, hot rolling temperature was set to 1000°C. Finite element model of treated material was developed, displacement in deformation zone during hot rolling and vector field of metal movement were determined. Changes in force during treatment, deformation stress during rolling were determined. Changes of rolling force in deformation zone in course of time were determined. Distribution of active stress in deformation zone was investigated. Investigations allowed us to determine energy consumption of rolling process depending on reduction modes, which provided rational treatment modes.
