    摘要: A hot-rolling stand including blocks arranged in the stand windows and having hydraulic piston cylinder units provided as bending devices which are able to transfer bending forces via guide elements onto the chocks of the working rolls. For each block a double-acting hydraulic piston cylinder unit is provided whose two ends are connected with the guide elements. The guide elements have guide that engage both sides of the free ends of noses of the working roll chocks so as to permit axial movement of the working rolls.

    摘要: 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.

    摘要: The invention relates to a method for rolling up a metallic strip (1), in particular a steel strip, to a coil (2), the strip (1) being kept under longitudinal tension between a driver (3), consisting of at least one driver top roll (4) and at least one driver bottom roll (5), and a winding pin (6). The strip (1) is rolled up on the winding pin (6) to form the coil (2). In order to prevent the undesired opening of the wound coil in a simple manner, a bending moment (MB) is initiated in the strip, said bending moment acting perpendicular to the longitudinal direction of the strip (1) and causing a plastic deformation when a defined remaining length of the strip (1) is reached. The invention also relates to a device for rolling up a metallic strip.
