Definitions

  • the invention relates to a method for producing hot-rolled steel strip continuously cast supporting strip in at least two deformation stages, each with one or more rolling stands, in which in the first deformation stage with the Exit speed of the pre-strip rolled out of the continuous caster and that intermediate belt produced before the second deformation stage Exit speed from the first deformation stage wound into a bundle is processed after reaching the bundle weight and with Piercing speed of the second deformation stage for finish rolling and is then wound into the desired finished bundle sizes.
  • a generic method is for example in the German patent 38 40 812 C2 and has become known in the literature as the ISP process.
  • the main characteristic of this process is the two-stage rolling process first deformation stage directly after the casting machine Casting speed occurs and its second stage of deformation at one clearly higher rolling speed is carried out.
  • These two are coupled Rolling stages through an intermediate winding system in the form of a reel furnace, in after which the continuously cast slab is rolled into a bundle whose weight corresponds to the desired finished coil weight.
  • the Subdivision of the strand which is initially endless is therefore carried out subsequently the first stage of deformation when that coil weight in the reel furnace is reached, the weight of the finished bundle after being rolled out in the second Deformation level is the same.
  • the method steps according to the invention increase the buffer capacity of the Intermediate winding system clearly. With a winding capacity of around 100 tons for example, the buffer capacity would be 60 minutes per inter-bundle increase. As a result of the higher final rolling speeds with such Procedure is possible, hot strip with thicknesses ⁇ 1.2 mm be made endless. The output of the plant is improved, since only for the beginning of the first and the end of the last bundle behind the finishing train developed typical rolling tongue, which must be removed before further processing. In addition, the quality of the rolling stock can be improved since the unsteady The piercing condition only occurred once on the first fret.
  • the winding of the intermediate band into an intermediate band can be both thornless as well as on a mandrel. Beyond one another Feature of the invention by changing the temperature control before winding of the intermediate collar and / or before the second deformation stage and by flexible Speed control the metallurgical properties within a Inter-bundle length changeable.
  • the advantages of the present method are Possibility of endless rolling without pre-weld, endless rolling with homogeneous opening properties with regard to temperature and geometry, the Production increase of the plant through higher possible rolling speeds are no longer restricted by the threading process in the reel and by the Creation of large buffer capacity between the casting line and the finishing train.
  • the process can be used within single or double-leg systems be, the winding principle of the supporting strip both mandrel-bound in winding furnaces as can be done without spines in so-called coil boxes.
