“…Modern technologies including the thermomechanical controlled rolling process (ТМСР) and the latest equipment [1,2], which have been developed recently, have given impetus to the production of rolled products with a new level of quality characteristics, including requirements for microstructure, shear fracture area, increased impact requirements, correlation of yield strength or tensile strength and others. When developing a new technology and mastering a new product mix, with increased requirements, manufacturers and scientists are faced with problems [3,4] that require further study. The way of solving one of these problems, namely providing increased requirements for these quality parameters, is to study the influence of the deformation degree on the stress distribution that occurs in the metal during rolling, and its penetration through the thickness of rolled products along the deformation zone at different temperatures.…”

In the paper the research has been performed to obtain the stress distribution through the thickness of the rolled products along the deformation zone in the conditions of roughing rolling and in the conditions of quasi-stationary temperature distribution during finishing rolling at the Steckel mill. The research has been performed by the simulation based on the Abaqus CAE 6.14-2 software and analytical modeling of the hot rolling process of coils at the Steckel mill with dimensions of 15 mm × 1500 mm, made of steel grade S355JR+AR, according to the requirements of EN 10025-2. The obtained deviations of the rolling force between simulation, analytical modeling and actual data have comparable results and a similar trend of changes through the passes, the average value of which does not exceed 1.54 % and - 1.77 %. The beginning of the continuous layer formation of equivalent stress during roughing rolling has been determined, and, accordingly, the beginning of the deformation penetration through the entire thickness of the semi-rolled product has been also determined that occurs in the pass 6 when reduction equals 14 %.
