Definitions

  • the invention relates to a continuous fine steel wire or wire, comprising, arranged behind the first intermediate rolling section of the road intermediate blocks andarrangedfertigblöcke before and between, and arranged behind these cooling sections and temperature compensation lines, and these downstream rolling stock collection facilities, wherein a plurality of, in substantially parallel guide lines for the rolling stock via intermediate points and deflections connected to one another, enable guiding of the rolling stock strand coming from the intermediate section of the road via predetermined sections of the guide lines and the rolling and cooling units arranged therein, as well as cooling and temperature compensation sections ( see eg EP-A-1 038 600 ).
  • Wire mills of this design represent the technical requirements for, for example, temperature-controlled rolling, with which the mechanical properties of the rolling stock can be improved, the heat treatment processes downstream of the rolling process can be saved and controlled temperature profiles within the rolling line can be set.
  • thermo-mechanical rolling because of the high final rolling speeds in finish rolling, places it in the rolling units with short framework spacings formed as intermediate blocks and as a custom prefabricated block and the associated rolling units Heating the rolling stock during rolling particularly high demands on the temperature control which usually requires a reduction in temperature to certain levels before the finish rolling.
  • a guide path which is supplied to the rolling stock from the intermediate portion of the wire path, in addition to cooling units and temperature compensation lines arranged in tandem, an intermediate block and a chronologicalfertigblock, one of which can be brought out of the rolling line as needed.
  • a guide switch is arranged, which leads to a second guide track, in which a third finished block is arranged, and the return over two bypasses and one, before the first-mentioned finished block in the first guide track guide back into this guide path.
  • EP 606 966 B1 Another proposal goes to supply the coming out of the intermediate section of the wire rod rolling stock via an intermediate switch either in a, equipped with cooling lines and a finished block and other intermediate points guide line or in a second, also equipped with a finished block and cooling lines, parallel guide line directly to the rolling stock collection device or with the help of a guide switch arrangement between the two guide lines, the rolling stock initially in the first-mentioned guide line through the finished block arranged in this finished and then by the, located in the parallel guide line finish block to roll and fed to the rolling stock collection device.
  • an intermediate switch either in a, equipped with cooling lines and a finished block and other intermediate points guide line or in a second, also equipped with a finished block and cooling lines, parallel guide line directly to the rolling stock collection device or with the help of a guide switch arrangement between the two guide lines, the rolling stock initially in the first-mentioned guide line through the finished block arranged in this finished and then by the, located in the parallel guide line finish block to roll and fed to the rolling stock collection device.
  • the material properties of the rolling stock can be controlled by the choice and use of the intermediate blocks and the finishing roll units and the length of influence of the cooling units and the temperature compensation lines influenced and also the different requirements when rolling small and large dimensions are taken into account. This, however, to a more or less limited extent.
  • the invention has for its object to improve this embodiment of the rolling train so that the Walzgut für in conjunction with adapted influencing of the material properties by the cooling units and the temperature compensation lines is made possible to a much greater extent and with a greater number of variations.
  • the rolling mill has three guide lines behind the preceding intermediate section, of which the first opens in front of the rolling stock collecting device via an intermediate switch in the second guide line, a first intermediate block and this downstream cooling and / or temperature compensation sections and behind the intermediate block an intermediate switch has, which leads to a 180 ° -Um Entry, which leads into an intermediate switch in the third guide line, which leads over a 180 ° -Um Entry with the beginning of the second guided directly to the rolling stock collection guide line, wherein before or behind the intermediate switch another intermediate between a downstream 180 ° -Um Entry is arranged, which opens via an intermediate switch in this guide line, behind the output of an arranged in this guide line intermediate block.
  • the intermediate switch at the output of the second guide line designed as a three-arm switch, with its third arm reversing over a 180 ° lead in the output of the third guide line.
  • This wire rod can, as the invention further provides, be operated in a working method such that the rolling stock coming from the intermediate section of the rolling train via the first guide line with the intermediate block and the cooling sections and temperature compensation lines via a bypass in the third guide line and from this via a detour in the second guide line with the intermediate block and the cooling sections and temperature compensation lines the structuredfertigblock and the rolling stock collecting device are fed.
  • the rolling stock can also be fed via the first guide line with the intermediate block and the cooling sections and the temperature compensation lines via the three-arm switch in the third guide line and a bypass and intermediate switch in the second guide line and from this the crudefertigblock and the rolling stock collection device.
  • the rolling stock is fed via the first guide line with the intermediate block and the intermediate switch and a bypass and a further intermediate switch of the third guide line and on this and a deflection of the second guide line with the intermediate block, the medicinalfertigblock and the rolling stock collection device ,
  • the wire rod can also be operated so that the rolling stock is fed via the first guide line with the intermediate block and thedestrekken and temperature compensation lines on the three-arm switch directly to the crudefertigblock and the subsequent rolling stock collection device.
  • the two working methods described in the first and second place at wire thicknesses of 5.0 and 11.0 and 11.0 to 22.0 mm allow intensive cooling with good temperature compensation and low inlet, outlet and finish rolling temperatures in the intermediate blocks and the diaryfertigblock, while in the subsequently described two working methods for the mentioned wire thicknesses with lower cooling and higher inlet and finishing temperatures can be worked.
  • the rolling mill has three substantially parallel guide lines FL I, FL II and FL III between the output AG of the roll leading zoom leading first intermediate portion of the wire rolling line, not shown, and a 1-fertigblock MFB with upstream loop table ST and, this downstream, also not shown rolling stock collection device on, the cooling lines KS are upstream.
  • the first of the rolling stock guide lines FL I begins with an intermediate block ZB1 with upstream sling table ST, which is followed by a scissors arrangement SA with downstream sling table ST and this intermediate between ZW 1 with a straight line GA and a deflection arm AA.
