Purpose: New kind of reinforcement bars are bimetallic reinforcement bars which has a higher corrosion resistance and mechanical properties, than the standard bars. The bimetallic bars are more and more often applied to building of concrete construction. This kind of application decides about high requirements imposed upon their performance characteristics and mechanical properties. Design/methodology/approach: Using the numerical modelling to rolling process of the bimetallic reinforcement bars in a finished pass to define rolling parameters. The simulations of the ribbed bar rolling were carried out using the Forge2005(R) commercial program. 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. 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 bimetallic reinforcement bars is very difficult. One from many problems during production bimetallic bars is rolling in the finished passes. In this paper the computer simulation of the rolling bimetallic reinforcement bar is presented.
