Definitions

  • the invention relates to a method for processing a slab in a device having at least one furnace, at least one downstream of the furnace in the conveying direction of the slab processing device and one of the at least one processing device in the conveying direction of the slab downstream rolling mill, wherein means are present a force may be exerted on the sides of the slab to move the axis of the slab in accordance with a predetermined position transverse to the conveying direction of the slab, in particular in conformity with the axis of the rolling train. Furthermore, the invention relates to a device for processing a slab.
  • a strip from a slab for example a thin slab

  • a tunnel furnace roller hearth furnace
  • the slab can run laterally.
  • Subsequent threading into the finishing train becomes more difficult due to this offset.
  • a stuffer is often provided before the finishing train.
  • side guides are typically arranged to direct the slab to the axis of the rolling train.
  • the stuffer or the mechanical guides must therefore be wide open at the head and are usually adjusted to a narrower guide position only after the safe threading in the first horizontal stand of the finishing train. Because of the unfavorable conditions or because of the risk that slabs get stuck on the stuffer, the stuffer at the top of the slab is not used.
  • DE 601 01 340 T2 discloses a generic method and a corresponding device. After this, a slab centering is provided in the last oven part. Here, guide rollers are briefly driven into the furnace, which contact the side of the slab and exert a force on it, thus centering the slab. However, this is a very maintenance-intensive procedure, since the guides are often exposed to the high furnace temperatures. The disadvantage here is also that the furnace atmosphere is adversely affected by the constant lateral opening of the furnace to the entry of the rollers. Increased scale caking on the oven rolls and additional slab scaling are the result. Despite being centered in the oven, there is still a risk that the slab will be laterally behind the oven, ie behind the oven in the conveying direction. In S-shaped or saber-shaped slab shape achievable with the known solution centering is also limited.
