In order to study processes occurring during manufacturing of thin steel sheet by cold rolling and change of energy-power parameters, simulation was performed using engineering software DEFORM 3D, which allows to reflect rolling technology accurately. Model of treatment process was created, output data, modes and temperature of treatment, motion parameters of rolls and sheets were set, material of workpiece was selected and its properties were determined. During simulation of sheets cold rolling process, Lagrange analysis was used, number of simulation steps was 100. Process of plastic deformation of metal along curved grid was investigated, vector displacement field was determined, and it was found that maximum movement of metal occurs under effect of top roll. Distribution of stress-strain state was investigated and maximum stress in strain zone was determined. Distribution of rolling forces and torque was investigated, which allowed to determine their maximum values. Maximum rolling forces and torque were observed at 7 – 9 th second of treatment, and in future they were reduced due to the fact that pushing force disappeared and steady process began.
