    Abstract: The invention relates to a method and device for producing metal sections having two profile flanges arranged opposite one another and having flange inner faces that are to be kept apart from each other by a closely toleranced final chamber dimension. In order to adapt the chamber dimension from a starting chamber dimension K0 to a desired final chamber dimension K1, the metal section is passed through the device, which forms working gaps between an inner working roll pair and outer support rolls. The working rolls that form the inner working roll pair roll over each other in order to brace the forming forces exerted on the working roll pair from the flange inner faces against each other.

    Abstract: In a rolling train, prior to being rolled, the rolled stock, or slab, produced in an ingot casting process, has the shape of a truncated pyramid with a base area, a top area and four side areas. During a first rolling pass sequence, two opposite side areas of the rolled stock are rolled in a first direction so that all of the cross-sectional areas of the rolled stock oriented transversely with respect to the rolling direction have the same surface area when the sequence ends. The rolled stock is rotated, e.g., through 90°, and during a second rolling pass sequence, the same two opposite side areas of the rolled stock are rolled in a second direction transversely with respect to the first direction. Thus, material of the rolled stock is automatically redistributed to a desired geometry with a high degree of precision and without the use of vertical rolling stands.

    Abstract: A roller guiding system for thin strips (20) at a rolling system outlet which allows a safe guiding without take-off and consequent tipping/folding of the head of the strip and without cobbles even at high feeding speeds. The system of the invention prevents the strip from impacting or sliding on the upper containment devices (8) or on the rollers (4?) by its upwards or downwards movement, thus avoiding possible damages to the surface, such as scratches or lines. Furthermore, such a guiding system acts on the mechanical-aerodynamic phenomenon which causes instability in the head moving by making a self-centering guiding system which is thus suitable for improving the winding quality of the coil itself.

  • Patent number: 8429943
    Abstract: When rolling hot-rolled strips, different draughts per pass might occur during the rolling operation over the length of the roll gap, due to changes in the hardness of the rolling stock, to the roll gap itself or to the geometry of the incoming rolling stock. These different draughts per pass lead to lateral deviations and shifts of the rolling stock in the roll stand and to a lateral bending of the outgoing hot-rolled strip. In order to avoid these defects by intentionally influencing the geometry of the rough-rolled strip, it is proposed to interconnect in at least one roughing-down stand a dynamic positioning in the roughing-down stock (1) with fast and powerful lateral guides (8,9) arranged before and after the roughing-down stand (1), by corresponding regulation operations, in such a way that a grainy or tapering bloom (4) is shaped into a straight and taper-free roughed-down strip (5) in one or more passes, in continuous or reciprocating operation.

  • Publication number: 20120151983
    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 budding and overlapping.

  • Patent number: 7861567
    Abstract: An apparatus to control lateral motion of a bar moving along a guidance path includes a pair of rotatable hubs each having at least first and second rollers at locations around the perimeter of the hub. The first roller has a first retaining groove of a first radius and the second roller has a second groove of a second radius smaller than the first radius. Each hub further includes at least one guiding element located between the rollers with a guide channel extending in the outer surface. A mounting system allows the hubs to be rotated between first and second positions. In the first position the first rollers oppose each other forming a guideway having a first, enlarged diameter for capturing a free end of an approaching bar. In the second position the second rollers form a second, smaller diameter to match the actual size of the bar.

  • Publication number: 20100326154
    Abstract: A cold-rolling train has a plurality of rolling stands and a strip feeding device to which an initial setpoint speed is sent to feed the cold strip to the first stand at an initial actual speed corresponding to the initial setpoint speed. A first setpoint speed is sent to the first stand so that associated rolls rotate. Between the first and next passed-through rolling stand is a thickness detection device detecting a first actual thickness. A base output signal is determined using the first actual and setpoint thicknesses and is used to adjust the first setpoint speed, but not the initial setpoint speed, conforming the first actual to the first setpoint thickness. Between the feeding device and the first rolling stand is an initial thickness detection device detecting an initial actual thickness. The initial setpoint speed is adjusted by a initial feed-forward controller to adjusted a setpoint product mass flow.
