Definitions

  • the invention relates to a method for producing sheets from a magnesium melt.
  • An advantageous way of producing strips with a certain thickness is the so-called "casting rolling", in which a molten metal is cast into a strip with a near final thickness and immediately hot rolled inline to form a hot strip. The resulting cast and hot rolled strips are then further processed. In this case, further rolling steps or other forming operations as well as annealing treatments can be included ( DE 100 52 423 C1 ).
  • the width of the strips produced in this way is limited by the width of the nip of the rolling stand used for their forming.
  • By slitting only so-called “slit strips” can be divided from these bands, the width of which is smaller than the width of the starting product.
  • users of such flat products are not only required to have a wide spectrum Different thicknesses, but also adapted to the particular purpose widths are required that go beyond the producible on conventional rolling mills widths.
  • sheets produced according to the invention have good mechanical properties and a favorable microstructure for their further processing.
  • the deviations between the properties determined in the longitudinal, transverse and diagonal directions of the sheets produced according to the invention are slight.
  • the positive effects which are already described in the technical literature for a rolling of magnesium sheets with multiple changes of direction thus already arise in the method according to the invention Beck, Adolf "Magnesium and its alloys", Springer Bln, 2nd edition 2001, chapter: Technology of rolling ). It is surprising in that the property improvements achieved in the inventive manner of rolling occur, although the separated from the strip sheets are only once moved so that their orientation during rolling from the orientation, with which the strip has been rolled.
  • the production line 1 comprises a melt vessel 2 from which magnesium melt S is continuously conveyed via a nozzle 3 into the pouring gap (not shown) of a two-roll strip casting machine 4.
  • the finished, final annealed sheets Bf have good mechanical properties.
  • the yield strengths R p0.2 were in the range of 165-170 N / mm 2
  • elongations A 50 in the range of 15-20%.
  • Diag. Figure 1 compares the R m , R p 0.2 and A 50 values for longitudinal and transverse rolled sheets, with the values shown as lines representing the longitudinally rolled material and the rectangles, points and stars representing the measured values for cross rolled material.
