ABOUT CONDITIONS OF RECEIVING HIGH-STRENGTH COLD-DEFORMED REINFORCEMENT WITH USING OF NON-DRIVING ROLLING STAND

Abstract

The energy-power parameters of applying a periodic profile to a remaking bars are determined. For the considered sizes of calibers, the maximum value of the forces acting on the rollers, as well as the values of the required pulling force, are established. The influence of the depth of dents of the profile on the bearing capacity of high-strength reinforcing steel is studied. It was experimentally established that after applying the profile and stabilization, the loss of the bearing cross section of reinforcing steel by 5.0 % is compensated by an increase in Rm and R0.2. The proposed methodological approach based on the modeling of the technological process and the assessment of the complex of its parameters allows you to design equipment for profiling the remaking bars, integrated into the common line of the stabilization section together with the pulling device.
