  • Wire mills of this type are the technical prerequisite for e.g. temperature controlled rolling with which the mechanical properties of the rolling stock improved, heat treatment processes downstream of the rolling process saved and controlled temperature profiles within the rolling line can be adjusted.
  • thermomechanical rolling poses because of the high finish rolling speeds during finish rolling in the, designed as intermediate blocks and as a finished block Rolling units with short stand distances and the associated Heating the rolling stock during rolling places particularly high demands on the Temperature control which usually reduces the temperature to a certain level Values required before finish rolling.
  • EP 606 966 B1 goes there, from the intermediate section the rolling mill coming from the wire mill via an intermediate switch optionally in one, with cooling sections and a finishing block as well as further intermediate switches equipped guide line or in a second, also with a prefabricated block and cooling lines equipped, parallel guiding line feed directly to the rolling stock collection device or with the help of a Guide switch arrangement between the two guide lines the rolling stock first in the first-mentioned guide line through the one arranged in it Finished block and then by the one in the parallel one The finished block and the rolling stock collecting device supply.
  • an intermediate switch optionally in one, with cooling sections and a finishing block as well as further intermediate switches equipped guide line or in a second, also with a prefabricated block and cooling lines equipped, parallel guiding line feed directly to the rolling stock collection device or with the help of a Guide switch arrangement between the two guide lines the rolling stock first in the first-mentioned guide line through the one arranged in it Finished block and then by the one in the parallel one The finished block and the rolling stock collecting device supply.
  • the invention has for its object this form of training of the rolling mill to improve so that the rolling stock processing in connection with adapted Influence of the material properties through the cooling units and the temperature compensation sections to a much larger extent and with a larger one Number of variations is made possible.
  • the rolling mill is behind the previous one Intermediate section has three guide lines, the first of which is in front the rolling stock collecting device via an intermediate switch in the second guide line opening, a first intermediate block and, this cooling and / or downstream Temperature compensation sections and one behind the intermediate block Intermediate switch which leads to a 180 ° bypass, which leads to an intermediate switch in the third guideline that leads through a 180 ° bypass with the beginning of the second one leading directly to the rolling stock collecting device Guide line leads, with another intermediate switch in front of or behind the intermediate switch is arranged with a downstream 180 ° bypass, which an intermediate switch in this guide line, behind the exit one, in this Guide line arranged intermediate block opens.
  • the intermediate switch at the exit of the second guide line as a three-arm switch trained, with her third arm reversing into the Lead the exit of the third guideline.
  • This wire mill can, as the invention further provides, in a working process be operated such that the from the intermediate section of the rolling mill coming strand of rolled material over the first guide line with the intermediate block and the cooling sections and temperature compensation sections via a bypass in the third guideline and from this via a transfer to the second guideline with the intermediate block and the cooling sections as well as temperature compensation sections fed to the custom-made block and the rolling stock collector become.
  • the strand of rolled material can also pass over the first guide line with the intermediate block and the cooling sections and the temperature compensation sections via the three-arm switch in the third guideline and via a detour and intermediate switch into the second guide line and from there the finished block and the rolling stock collection device be fed.
  • Another possibility according to the invention is that the rolled material strand over the first guide line with the intermediate block and the intermediate switch as well a detour and another intermediate switch of the third guideline and about this and a bypass of the second guideline with the intermediate block, is fed to the custom-made block and the rolling stock collection device.
  • the wire mill can also be operated in such a way that the rolled strand over the first guide line with the intermediate block and the cooling lines as well as temperature compensation sections directly via the three-arm switch the custom-made block and the subsequent rolling stock collection facility becomes.
  • the two working methods described in the first and second place enable For wire thicknesses of 5.0 and 11.0 and 11.0 to 22.0 mm, roll with intensive cooling with good temperature compensation and low inlet, outlet and finish rolling temperatures in the intermediate blocks and the made-to-measure block, while in the two working methods described below for the wire thicknesses mentioned with lower cooling and higher inlet and finished temperatures can be worked.
  • the rolling train has three essentially parallel ones Guide lines FL I, FL II and FL III between the exit AG of the Rolling line leading first intermediate section of the not shown Wire rolling mill and a customized finishing block MFB with upstream loop table ST and this subordinate, also not shown rolling stock collecting device on the cooling sections KS are arranged.
