Abstract
Procedure for the manufacture of a concrete reinforcement rod made by cold deformation, in which a steel rod produced by hot rolling is first placed in a roughly triangular cross-sectional shape and then obliquely positioned cross ribs are made in the deformed rod, by means of cold profiling rollers that impinge on the corners throughout the length of the triangular rod, which transverse ribs open plainly at the beginning and at the end at the periphery of the triangular rod, so that the projection of the envelope in the axial direction of the rod, is almost circular, characterized in that the cross section of the rod, in the first cold deformation operation (previous pass), deforms becoming a triangle with bulged sides, in which the ratio of the radius of curvature of the bulged sides of the triangle to the radius rV1 of the circle inscribed of this triangle is of (see formula) and preferably 1.7, in cross section decrease of approximately 18% in the rib pass and 2.0 in cross section decrease of approximately 24% in the rib pass and in that the radius rV1 of the inscribed circle of this triangle is at most equal to the distance kR of the center point of the cross section from the edge of the rib pass between the openings of the rollers of the rib mill.
