Purpose. To justify the need to improve the production technology of steel reinforcement hardened by cold deformation and propose new schemes for these technologies. Methodology. On the basis of a comparative analysis of existing methods for the production of steel reinforcement hardened by cold deformation, new schemes of the technologies under consideration are being developed and justified. Findings. New schemes for the production of steel reinforcement hardened by cold deformation, which allow to obtain the required level of hardening and the optimal structural state. Originality. For the first time, it was proposed to use cold deformation in the production technology of steel reinforcing bars and parameters that allow not only to carry out the necessary hardening, but also to form optimal dislocation structures, which in many respects eliminate the manifestation of the negative properties of cold-formed steel products. Practical value. The proposed technologies for the production of steel reinforcement hardened by cold deformation can improve the environmental friendliness of these processes and get reinforcing bars with properties corresponding to the operating conditions.
