  • Publication number: 20070261456
    Abstract: In a rolling mill for rolling metal strip (1), especially steel strip, which has at least one rolling stand (2), an upstream coiler (3), and a downstream coiler (4), wherein an “S” roll unit (5, 6), which has two rolls (7, 8; 9, 10) that guide the strip (1) in the form of an “S”, is arranged between the upstream coiler (3) and the rolling stand (2) and/or between the rolling stand (2) and the downstream coiler (4), the invention provides that a first roll (7, 9) of the “S” roll unit (5, 6) is arranged in a fixed manner, and a second roll (8, 10) of the “S” roll unit (5, 6) is arranged in such a way that it can move relative to the first roll (7, 9).

  • Publication number: 20050172893
    Abstract: The invention relates to a device for hot dip coating metal strands (1), particularly strip steel, in which the metal strand (1) can be vertically guided through a reservoir (3), which accommodates the molten coating metal (2), and though a guide channel (4) connected upstream therefrom. An electromagnetic inductor (5) is mounted in the area of the guide channel (4) and in order to retain the coating metal (2) inside the reservoir (3), can induce induction currents in the coating metal (2) by means of an electromagnetic blocking field. While interacting with the electromagnetic blocking field, said induction currents exert an electromagnetic force. In order to prevent an intense heating of the metal strand caused by the electromagnetic inductor, the invention provides that the inductor (5, 5a, 5b) is connected to electric power supply means (6) that supply the inductor with an alternating current whose frequency (f) is less than 500 Hz. In particular, a mains frequency of 50 Hz is intended.

    Abstract: The invention relates to a device for hot dip coating metal strands (1), particularly strip steel, in which the metal strand (1) can be vertically guided through a reservoir (3), which accommodates the molten coating metal (2), and though a guide channel (4) connected upstream therefrom. An electromagnetic inductor (5) is mounted in the area of the guide channel (4) and in order to retain the coating metal (2) inside the reservoir (3), can induce induction currents in the coating metal (2) by means of an electromagnetic traveling field. While interacting with the electromagnetic traveling field, said induction currents exert an electromagnetic force. The inductor (5) has at least two main coils (6) that are arranged in succession in movement direction (X) of the metal strand (1), and has at least two correction coils (7) for controlling the position of the metal strand (1) inside the guide channel (4) in direction (N), which is normal to the surface of the metal strand (1).
