Methods: theoretical - numerical methods of the pressure treatment, the method of slip-line fields, the upper bound method, finite element method, experimental - physical modeling. The purpose of research - extension mix, quality and economy of material resources in the production of metal figurine. Theoretical and practical results: the complex of mathematical models rolling and straightening angle profiles, transverse and cross-wedge rolling bodies of revolution. Experimentally confirmed the accuracy of the theoretical results. Developed a tool for practical implementations of mathematical models. Practical recommendations for improving technology and equipment rolling and straightening angle profiles, transverse and cross-wedge rolling axisymmetric metal to improve the quality of metal and cost of material resources. Novelty: further developed methods for calculating the stress-strain state and quality in the hot bar rolling and straightening angle steel, transverse and cross-wedge rolling bodies of revolution. Updated quantitative and qualitative nature of the effect of technological and design parameters on the power parameters of these processes and the quality of metal figurine. Efficiency of implementation: results allow for 8 ... 17% increase in the accuracy of modeling and forecasting performance of complex structure of metal rolling processes, increase accuracy of rolled products, reduce development costs of technologies and equipment for rolling and changes and their further exploitation. Scope: technology and equipment bar rolling processes and changes. The results of research relating to the rolling and straightening angle steel can be used to improve technologies in Kramatorsk, Makeevka, Enakievo Steel, Alchevsk and Dnepropetrovsk metallurgical plants, PJSC "ArcelorMittal Krivoy Rog" and others, in the development of equipment of PJSC "Novokramatorsk Engineering Works". The results relating to the rolling bodies of revolution, are recommended for use in machine-building enterprises, including small businesses.
