摘要：

Stages are considered for the development of thermal strengthening technology in different classes of reinforcing bar at the West Siberian Metallurgical Combine. The structural evolution of devices for thermal strengthening of reinforcement 10-50 mm in diameter in a bar rolling mill line, and also production developments for optimizing interrupted hardening regimes are analyzed. Results of metallographic and electron-microscope studies of the structural composition formed in a bar cross section are used to demonstrate thermal strengthening of A500S class reinforcement No. 32 from steel 18G2S. The effect of induced cooling regimes on the strength of reinforcing bar and individual layers of a structural composite is analyzed. It is established that the main contribution to strength improvement is made by hardened structures of the surface layer. Continuous improvement of thermal strengthening technology and devices makes it possible to increase production efficiency for reinforcing bar due to a reduction in alloying used for the steels.
