Abstract: A method to check and control a roller bending machine for continuously bending an elongated workpiece at variable curvature radii in a bending machine using a series of rollers for bending, comprises the steps of measuring the distance of the elongated work piece in a point that is situated downstream the series of rollers for bending in successive instants, calculating a curvature radius of each bend section of the elongated workpiece, comparing the calculated curvature radius with the desired curvature radius and determining a difference between them, calculating the change of position to which an upstream roller has to be subjected in order to annul such a difference and operating the upstream roller on the base of the calculated change of position. A machine embodying the method is also described.

Abstract: A method for operating an apparatus for decelerating and temporarily accumulating a hot rolled long product. The product is deposited on a rotating drum in the form of a helix, and is simultaneously unwound from the drum to a receiving guide movable incrementally along a path parallel to the rotational axis of the drum. Immediately upon entry of the product front end into the receiving guide, the incremental movement of the receiving guide is preceded by an initial rapid shifting through a distance adequate to prevent subsequent product convolutions of the helix from buckling and overlapping.

Abstract: A rolling monoblock comprises: a first block (B1) of rolling stands (G1-Gm) and a second block (B2) of rolling stands (Gm+1-Gn). According to the invention, an annular path (A) of cooling of the rolled section (11) is foreseen between the two blocks (B1, B2).

Abstract: Between an intermediate roll unit and a dimensioning finishing roll unit of a continuous light-section or wire rod rolling train, a multifunctional section is provided with three parallel lines and at least the first and second rolling lines having rolling blocks and substantially all of the lines including cooling sections and/or temperature equalization sections. Via distributing guides and 180° loop forming path segments, the workpieces are selectively directable from the first line to the dimensioning finishing rolling unit without traveling over the second and third lines and to the dimensioning finishing rolling unit after travelling over all or part of the second and third lines.

Abstract: In a rolling-mill installation for the continuous production of fine steel includes a roughing block, a finishing block arranged on the rolling line of and after the roughing block, a water cooling section arranged after the finishing block and on the rolling line and a laying unit arranged downstream. In order optionally to be able to carry out rolling processes in accordance with conventional rolling or thermomechanical rolling, the finishing block arranged on the rolling line of the roughing block can be moved into a rolling position at a distance from the rolling line of the roughing block and back again. A rolled-material diverter is arranged downstream of the water cooling section by which the rolled material can optionally be routed on the one hand to a laying unit and on the other hand, via a soaking section, to the finishing block which has been moved at a distance from the rolling line of the roughing block.

Abstract: A rolling mill for wire or bar steel with a continuous light section steel or wire train, comprising a single or multi-line breakdown train with pilot stands, at least one single intermediate train comprising a cooling distance with subsequent soaking distance and a group of intermediate stands located downstream of said breakdown train as well as a finishing train downstream of said intermediate train with a single line group of finishing stands is disclosed, for overcoming unequal temperature distributions across the bar length and cross-section to compensate for varying finishing velocities because of cross-sectional differences caused by unavoidable longitudinal pull between the stands of the breakdown train. Specifically, a first soaking or compensation distance 10 with 180.degree. loop of the rolled stock guided through the horizontal loop former is located between the pilot stand and the group of intermediate stands and a second compensation or soaking distance with 180.degree.

Abstract: An apparatus for receiving the intermediate product of a rolling finishing mill. The apparatus incorporates an oven (40) to receive the intermediate product from the roughing stand (11) of a rolling mill. A first concave surface (16) of a deflector (13) directs the travel of the intermediate product from the roughing stand (11) to the oven means (40). Driven pinch rolls (36) selectively advances the intermediate product from the deflector (13) to the oven (40). Oscillating guides (44,45) within the oven (40) permit the intermediate product to be foldedly layered therein. When the intermediate product is substantially contained within the oven means (40) it is selectively secured at one end by clamp members (22,23) in a fixed position relative to the deflector (13).

Abstract: A continuous rolling line and method for rolling wires or bars is provided using at least one repeater rolling unit of at least two roll stands having a rolled stock loop between them and a multi-stand continuous rolling unit spaced from and receiving rolled stock from the repeater rolling unit.
