Production equipment of cold deformed reinforcing hire with the wide range of consumer properties

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.
