REINFORCEMENT STEEL PRODUCING METHOD Russian patent published in 2006 - IPC B21C1/00 

FIELD: metallurgy, namely production of reinforcement steel for reinforcing concrete structures.

SUBSTANCE: method comprises steps of making reinforcement steel by cold deformation in two roller draw plates with crosses axes of their rollers; at deforming blank in gap between rollers of first draw plate forming periodical dents; at deforming blank in gap between rollers of second draw plate imparting to blank appearance of ready product and simultaneously forming periodical dents on it. According to invention deforming is realized through gaps formed by rollers with cylindrical working surfaces at elongation factor of first draw plate no more than 1.2 and at elongation factor of second draw plate no more than 1.6. At working of blank deformation is uniformly distributed in surface layers of blank along its perimeter providing homogenous structure while structure of central layers of blank remains the same, that is hot rolled structure.

EFFECT: improved plastic properties of steel.
