Definitions

  • the invention relates to a method for producing a hot strip of a conversion-free ferritic steel, in which a melt is cast into a precursor and this is then rolled into a hot strip.
  • Conversion-free ferritic steels are via the usual continuous casting route, i. H. Continuous casting of the melt into a slab or thin slab, which is rolled either in-line or separately to a hot strip, or not produced with the required properties.
  • the slab or thin slab produced by continuous casting has macrosegregations and forms voids.
  • the precursor has a very coarse grain and the casting powder is problematic due to the high aluminum content of the ferritic steel.
  • the specified upper limit for the thickness of 6 mm can not be achieved with the existing systems, the actual maximum thickness to be set is usually 4 mm, in special cases at max. 5 mm.
  • this thickness range is interesting, for example, for the use of the hot strip as a lightweight component in the exhaust system of vehicles.
  • hot strip as a lightweight component in the exhaust system of vehicles.
  • a low degree of hot forming means coarse grain, which has a negative effect on the ductility and thus on the formability of the hot strip.
  • the object of the invention is therefore to provide a method for producing hot strip from a conversion-free ferritic steel, with the fine while maintaining the advantages of the two-roll casting machine in the hot strip of 2-3 mm thickness can be set.
  • This object is achieved by a method in which the melt is flow-calmed in a horizontal strip casting plant and free from casting into a preliminary strip in the range between 6 and 20 mm and then rolled to hot strip with a degree of deformation of at least 50%.
  • the advantage of the proposed method is the fact that when using a horizontal continuous casting machine as a casting machine, the advantages of the known two-roller casting machine, such as reduction of Macroseiger Weggarten suppression of voids and avoiding G confusepulverproblematik, even at high Al contents in ferritic steel also come into play and beyond the thickness of the hot strip is considerably greater than the thickness of a hot strip produced by means of a two-roller casting machine.
  • the length of the conveyor belt is selected so that at the end of the conveyor belt before its deflection, the Vorband is largely solidified.
  • a homogenization zone which is used for temperature compensation and possible stress relief.
  • Rolling from pre-strip to hot strip can be done either in-line or separately off-line. Before off-line rolling, the pre-strip can be either directly hot-rolled or sliced into sheets prior to cooling after production. The strip or sheet material is then reheated after eventual cooling and unwound for off-line rolling or reheated and rolled as a sheet.
  • a preferred grade for the ferritic steel is one with high Mn levels up to
  • Another preferred grade is characterized by containing no Mn and no Si at comparable C, Cr and Al contents.
  • Both mentioned grades may optionally contain one or more precipitation-forming elements of the type B, Ta, Zr, Nb, V, Ti, Mo and W, totaling at most 2% by weight.

Abstract

La présente invention concerne un procédé pour produire un feuillard à chaud à partir d'acier ferritique non transformé, selon lequel on coule du métal fondu afin d'obtenir un préfeuillard qu'on va ensuite laminer pour obtenir un feuillard à chaud. A cet effet, le métal fondu s'écoule dans une installation de coulée en bande horizontale, de manière régulée et rectiligne, de façon à obtenir un préfeuillard d'une épaisseur de 6 à 20 mm qui sera ensuite laminé pour donner un feuillard à chaud présentant un taux de déformation d'au moins 50 %.
