Abstract

Purpose. Development based on the analysis of technological schemes for receiving the hardened reinforcing hire with use of hot and cold deformation and extension the list of requirements to consumer properties of this product technological line, providing  production  of  cold  deformed reinforcement with  a  periodic  profile  in  hanks, classes  of  durability  500...600  MPa.Methodology.  Comparable  system  analysis  of  technological  solutions  production  lines  for  production  of  cold-rolled reinforcement, that consists in comparison with the requirements of new normative documents on properties of armature, and also the analysis of complex influence of the deformation-thermal affecting properties of of cold-rolled reinforcement. Findings. The new complex of equipment, that is logistic organized as a production line by allowing stably getting cold deformed reinforcement in the wide range of different properties is offered. Originality. For the first time offered the composition of technological equipment in the logistics flow line for hardenable cold deformation rebar, structural state which formed the optimal combination of active and cyclic deformations with subsequent high-speed bulk and surface heat, ensuring the flow of the entire volume of the product static-dynamic strain aging, and the small softening the surface layer state.  Practical value. A line allows getting an armature conforming to the requirements  of  normative  documents  in  combination  with  enhanceable: relaxation  firmness,  plasticity,  corrosion  resistance,  fire resistance, resistance to cyclic loading and immunity to strain aging.
