Definitions

  • the invention relates to a method for the continuous production of a rolled metal strip from a molten metal, in particular a steel strip, wherein introduced in a first manufacturing step melt in a strip casting and a cast metal strip with vorgebarer bandwidth is discharged from this and in a subsequent second manufacturing step, the cast undivided metal strip in at least one rolling mill to Endbanddicke is roll formed, wherein the positioning of the metal strip in the roll gap by a rolling mill upstream of the band steering is effected by means of a Bandlenkennraum.
  • the invention further relates to a system for carrying out this method.
  • roller pair and the roll stand a dancer rolls in a belt loop to avoid a meandering tape run when entering the mill stand positioned ( Fig. 3 ).
  • a plurality of steering or driving rollers are spaced from each other in a temperature-controlled area in front of the rolling mill and necessary to avoid disturbing tape running (Fig. 7).
  • the object of the invention is therefore to avoid these disadvantages of the prior art and to propose a method and a device, whereby for the metal strip on the input side of the roll stand or the location of the rolling deformation in dependence on the strip dimensions with low investment costs a stable strip entry into the Roll stand is guaranteed.
  • Optimum tape running occurs when the metal strip is maintained in an area upstream of the mill stand, between a strip director and the nip, under a strip tension between 2.0 MPa and 15 MPa, preferably between 4.0 MPa and 8.0 MPa , If the strip tension is too low, the strip will run, eg due to unilateral compressive stresses. This is noticeable by instabilities, such as fluttering of the tape. On the other hand, with increasing strip tension, the risk of ligament tear increases. Since the belt temperature is kept high in this area, the strength of the metal strip is correspondingly lower and thus also the permissible pressure force that can be applied to the metal strip, without causing impressions of the drive rollers in it.
  • An additional stabilization of the tape run can be achieved if the metal strip is held in a region upstream of the tape steering under a belt preference.
  • the strip tension can be kept lower than in the subsequent inlet region of the roll stand and is used primarily to calm and support the emerging from the casting machine metal strip.
  • the strip preference is generated or adjusted by the weight of the metal strip sagging in a loop pit.
