FIELD: metallurgy; production of reinforcing bar steel.
SUBSTANCE: proposed plant is used for production of reinforcing bar steel by cold deformation method. Proposed plant includes two roller drawing dies; axes of their rollers intersect and working surface is provided with periodic profile ragging. Rollers have cylindrical surface and clearance between rollers is so selected that cogging in first drawing die is carried out at drawing coefficient not exceeding 1.12 and in second drawing die not exceeding 1.16. Provision is made for conducting cold deformation at which deformed zones are smoothly distributed in surface layers over entire perimeter of reinforcing bar steel keeping the structure of central layers non-deformed and hot rolled, thus making it possible to obtain steel with equilibrium structure possessing high ductility.
EFFECT: enhanced ductility of steel.
