Purpose: The paper presents the results of theoretical investigations of the process of rolling reinforcement bars designed for concrete reinforcement. In the investigation. particular consideration was given to the analysis of the effect of pre-finished band shape on the formation of ribs on the finished bar in the finished pass. Design/methodology/approach: Using the numerical modelling to rolling process of the reinforcement bars in a finished pass to define rolling parameters. The simulations of the ribbed bar rolling were carried out using the Forge2005® software. Findings: It has been performed in order to define the specific features of the mode of metal flow in the roll gap and to determine the effect of the shape and dimensions of the feedstock oval on the height of the ribs and on the thickness of surface layer of the finished bar. Research limitations/implications: The use of commercial software applications in the design of process technologies will allow for the development of reinforcement bars rolling technology with a minimum number of laboratory and industrial trials. Practical implications: Reinforcement bars are chiefly used in the building industry at production of reinforced concrete constructions. and as working elements in bridge building. Originality/value: Production of the reinforcement bars is very difficult. One from many problems during production the bars is rolling in the finished pass. In this paper the computer simulation of the rolling reinforcement bar is presented.
