Abstract
A method and an arrangement for severing and controlled cooling of individual rods from a rolled section, particularly from a section of preferably high-grade steel which emerges hot from rolling at final speed from the rolling line of a finishing train, wherein the section is divided during its passage through parting shears into cut lengths and wherein a cut length each is conveyed after severing to an annealing strip or an annealing furnace. The rolled section is supplied to parting shears whose knives rotate on both sides of the section in a horizontal plane and which, when severing the section, displace the resulting section ends in the horizontal plane laterally relative to each other by a certain distance.

A method for severing and controlled cooling of individual rods from a rolled section which emerges hot from rolling at final speed from a rolling line of a finishing train, the method comprising dividing the section into cut lengths as the section travels through rotation shears comprising knives which rotate on both sides of the section in a horizontal plane, wherein each cut length has an end and the section has a front end adjacent the end of the cut length, laterally displacing the end of the cut length relative to the front end of the section by means of cams as deflectors mounted at the knives of the rotation shears by a distance in the horizontal plane, wherein the distance is such that the front end of the section can travel past the end of the cut length, and conveying each cut length to a cooling unit.
An arrangement for severing and controlled cooling of individual rods from a rolled section which emerges hot from rolling at final speed from a rolling line of a finishing train, the arrangement comprising a cooling bed arranged next to the rolling line and parting shears mounted following the cooling bed in a direction of the rolling line, the parting shears comprising rotation shears with a first knife carrier carrying a first knife mounted on a first side of the section and a second knife carrier carrying a second knife mounted on a second side of the section, the knife carriers rotating synchronously in opposite directions in a horizontal plane, wherein each knife carrier is provided with a cam as a deflector for deflecting the individual rods, the cam of the first knife carrier being arranged behind the first knife in the direction of rotation of the first knife carrier and the cam of the second knife carrier being arranged in front of the second knife in the direction of rotation of the second knife carrier.
