Definitions

  • the invention relates to a non-grain-oriented metallic flat product, a method for producing a flat product and also a use.
  • metallic flat product includes in particular rolled products, such as steel strips or steel sheets, cut pieces or plates produced by casting.
  • the invention relates to flat products that are designed as electrical strip made of a steel and flat products that are designed as electrical sheet made of a steel.
  • Non-grain-oriented flat products especially non-grain-oriented electrical steel strip or sheet, are required in many electrical engineering applications.
  • NGO Non Grain Oriented
  • the non-grain oriented metallic flat product is used to control and amplify the course of electromagnetic fields.
  • Typical fields of application for such strips and sheets are rotors and stators in electric motors and electric generators.
  • non-grain-oriented metallic flat products are required, in particular non-grain-oriented electrical steel and non-grain-oriented electrical sheet, which combine comparatively low remagnetization losses at comparatively high frequencies with comparatively high magnetic polarization and induction as well as comparatively high permeability.
  • the invention is based on the object of providing alternatives to known flat steel products which meet the requirements to a constant or greater extent in terms of their magnetic properties.
  • the flat products to be provided should also be usable with very low final thicknesses of, for example, less than 0.35 mm.
  • the invention is solved with a flat product having the features of claim 1.
  • the invention is also solved with a method having the features of claim 5.
  • the invention also includes a flat product having the features of claim 6 and a use having the features of claim 8.
  • Ni, Cu, Sn, Co, Zr, Nb, V and Mo may be present as optional components, as long as the sum of the weight proportions of these elements does not exceed the limit specified above.
  • Mg and Ca may be present in amounts between 0.0005 and 0.005 wt.% due to the process and are included in the unavoidable impurities mentioned above within the scope of this description.
  • a decisive measure for providing a flat product with a combination of properties of advantageous magnetic properties and advantageous mechanical properties could be achieved by using the alloying specification according to the invention to considerably increase the Mn content and the Cr content of the flat product compared to known compositions of electrical strips or sheets.
  • the increased Mn content and the increased Cr content not only achieve a property profile of the magnetic properties within the desired values compared to materials with a high Si and/or Al content but low Mn and/or Cr content, but also yielded surprising results that indicate advantageous behavior under mechanical stress, for example during cold rolling. Both are explained and demonstrated in detail below in the description of manufactured examples.
  • the non-grain-oriented flat product is preferably non-grain-oriented electrical steel strip or non-grain-oriented electrical sheet, each made of a steel with an alloy composition according to the invention.
  • J 200;1000 > 1.0 which means that the magnetic polarization at a magnetic field strength of 200 A/m in an alternating electromagnetic field of 1000 Hz is greater than 1.0 T.
  • a particularly preferred flat product can be characterized alternatively or additionally by the surprisingly discovered property of the flat product that an increased content of Mn and Cr is established in the surface layers by annealing during the production process.
  • the flat product has in an edge layer, i.e. a boundary region to the surface, a content of Mn and Cr which, integrated over the volume of this boundary region, is a value of 0.2 or higher in relation to a content of Al and Si.
  • the flat product has, in the uppermost 0.95 micrometers below its surface, integrated over the volume of this boundary region, a content of Mn and Cr which, in relation to a content of Al and Si, is 0.2 or higher.
  • the flat product has a maximum thickness of less than 0.35 mm, with a thickness between 0.19 mm and 0.31 mm being particularly preferred.
  • the flat product is a sheet or a strip whose thickness meets the aforementioned criterion at every point.
  • the flat product is preferably available in the aforementioned low thicknesses, since the magnetic reversal losses are lower at these low thicknesses than at higher thicknesses. The improved processability of the flat product according to the invention therefore develops its particular advantages as a result of the expected excellent cold-rollability.
  • the preliminary product is heated to a preheating temperature of not more than 1200°C at the beginning of hot rolling.
  • the final annealing is preferably carried out in a continuously operated furnace through which the flat product passes, for example in a horizontal continuous furnace.
  • the final annealing described is carried out in one stage, but not in two stages.
  • steps A) to G) are carried out in their alphabetically specified order.
  • a further aspect of the present application is a flat product which is obtainable by one of the aforementioned processes or its further developments.
  • the final annealing takes place at a maximum temperature between 930-1070°C.
