Definitions

  • the invention relates to the finished section of a single-core wire rolling mill with two finishing blocks, one of which is in the rolling line of the intermediate rolling section the first rolling line and the other in one, are arranged parallel to this running second rolling line, for the optional Rolling small and large wire diameters, that of the intermediate rolling section led wire strand over a downstream of this section Switch can optionally be fed in and after rolling, if necessary via a switch can be introduced into a wire collecting device arranged behind it.
  • a wire rolling mill with a finished section of this type (EP 0 606 966 B1) has in addition to the switch upstream of the two parallel rolling lines behind this one in of the parallel first rolling line, the first finishing block and a transfer switch with wire guide to an introductory switch in the second rolling line on, behind which the second finishing block is arranged in this rolling line.
  • Such a trained finished section allows it, depending on the small to be rolled or larger diameters of the wire rod either the first finished block in to use one rolling line or the second finishing block in the other rolling line or also, by deflecting the wire rod strand from the one rolling line in to use the other two finished blocks in a row requires the mentioned additional switch arrangements and guides for the wire rod.
  • the object of the invention is to avoid this increased construction effort, to simplify the maintenance work and to make the system less prone to failure do.
  • This object is achieved in that in one rolling line, only for rolling of small wire diameters and in the other rolling line, arranged only for the rolling of large wire diameters intended block are. It can be used for rolling small wire diameters Prefabricated block made of one behind the other, each independently driven Pre and post blocks exist and further that for rolling larger ones Wire diameters certain block consist only of a roughing block.
  • the invention is based on the embodiment shown in the drawing explained in more detail.
  • the drawing shows the finished section of the wire rod mill in the Top view in a schematic representation.
  • the rolling line WL2 there is only one stand group corresponding to the post block NB1 NB2, here at the level of the NB1 post block. Behind this scaffolding group NB2 are also several cooling lines KS in front of the switch in the rolling line WL2 W2 arranged.
  • the finishing block FB1, the post block NB1 and the scaffolding group NB2 each have common drives, not shown here.
  • the finished section shown is operated in such a way that on the rolling line WL1 only the smaller wire diameters and on the rolling line WL2 only the larger ones Wire diameter are rolled, the cooling sections KS have guide tubes on the smaller in the rolling line WL1 to be rolled in this Wire diameters correspond to the larger wire diameters in the WL2 rolling line.
  • Both rolling lines WL1 and WL2 are advantageously operated alternately. For example. can after the wear of the rolling rings when rolling smaller diameters in the rolling line WL1 this is shut down and the rolling line WL2 now for rolling larger diameter to be put into operation and during this time the Roll stands of the rolling line 1 are serviced and equipped with new rolling rings. It is not necessary to replace the guide tubes in the cooling sections.

Claims (3)

  1. Section finie d'un train à fil-machine à une voie comportant deux blocs finis, dont l'un est disposé dans la première ligne de laminage s'étendant dans la ligne de laminage de la section intermédiaire du train et l'autre dans une deuxième ligne de laminage s'étendant parallèlement à celle-ci, pour le laminage au choix de diamètres de fils plus ou moins grands, dans lesquelles le cordon de fil amené en provenance de la section intermédiaire peut être acheminé au choix par un aiguillage installé en aval de ce cordon et peut, après le laminage, être introduit le cas échéant par un aiguillage dans un dispositif collecteur de fil disposé derrière cet aiguillage, caractérisé en ce que, dans une ligne de laminage (WL1) sont disposés un bloc fini destiné uniquement au laminage de petits diamètres de fil et, dans l'autre ligne de laminage (WL2), un bloc fini (FB1, NB1 ou NB2) destiné uniquement au laminage de grands diamètres de fil.
  2. Section finie selon la revendication 1, caractérisée en ce que le bloc fini destiné au laminage de petits diamètres de fil est composé de blocs avancés et postérieurs (FB1, NB1) disposés les uns derrière les autres et entraínés respectivement de manière autonome.
  3. Section finie selon la revendication 2, caractérisée en ce que le bloc fini (NB2) destiné au laminage de grands diamètres de fil est composé d'un seul bloc de laminage postérieur (NB2).
