摘要
The present invention provides a rolling method and apparatus for manufacturing concrete-reinforcing steel bars, wherein the invention provides for obtaining various concrete-reinforcing steel bars satisfying the required specifications for knot height while using the same finishing rolls even if the diameters of the final product steel bars are different. According to the present invention, two pairs of rolls (total of four rolls) each having a roll caliber and one or more knotting round calibers are used for the final finishing pass, and the two pairs of rolls are arranged to exert rolling pressures in two orthogonal directions on a raw material S.
