Definitions

  • the invention relates to a method for producing a strip of AlMgSi alloy, in which a ingot of an AlMgSi alloy is cast, the ingot is subjected to homogenization, the hot rolled to rolled slab is rolled, then optionally cold rolled to final thickness and finished rolled strip is solution-tempered and quenched. Moreover, the invention relates to advantageous uses of a correspondingly produced AlMgSi aluminum strip.
  • AlMgSi alloys whose main alloying constituents are magnesium and silicon have relatively high strengths in the state T6 with at the same time good forming behavior in the state T4 and excellent corrosion resistance.
  • AlMgSi alloys are the alloy types AA6XXX, for example, the alloy types AA6016, AA6014, AA6181, AA6060 and AA6111.
  • Aluminum tapes of AlMgSi alloy are produced by casting a roll bar, homogenizing the roll bar, hot rolling the roll bar, and cold rolling the hot strip. The homogenisation of the rolling ingot takes place at a temperature of 380 to 580 ° C for more than one hour.
  • the tapes can be delivered in condition T4.
  • the state T6 is set after quenching by thermal aging at temperatures between 100 ° C and 220 ° C.
  • the AlMgSi alloy strip has a maximum temperature of 130 ° C immediately after discharge from the last hot rolling pass and is wound at this or a lower temperature.
  • the hot strip By quenching the hot strip with this method, it was possible to produce aluminum strips in state T4, which in state T4 has an elongation at break of A80 of more than 30% or an equi-elongation Ag of more than 25%.
  • very high elongation at break values were found in the T6 state.
  • this temperature range at the outlet of the last hot roll pass leads to problems in the flatness of the hot strip, so that the subsequent manufacturing steps were disturbed.
  • the present invention based on the object to provide an improved process for the production of an aluminum strip of an AlMgSi alloy available, with which AlMgSi aluminum strips can be produced with a very good forming behavior in the state T4 process reliable.
  • the stated object of a method is achieved in that the hot strip immediately after leaving the last Hot rolling pass a temperature of more than 130 ° C, preferably 135 ° C to a maximum of 250 ° C, preferably 135 ° C to a maximum of 230 ° C and the hot strip is wound at this temperature.
  • this cooling takes place within the last two hot rolling passes, ie the cooling to more than 130 ° C, preferably 135 ° C to 250 ° C, preferably 135 ° C to 230 ° C within seconds, maximum within of five minutes. It has been found that in this procedure, the increased Gleichurgidehnungshong at usual strength or Dehngrenzhong in the state T4 and the improved hardenability in the state T6 are achieved particularly reliable process.
  • a process-reliable cooling of the hot strip is achieved by quenching the hot strip itself to coiling temperature using at least one sinker cooler and the hot rolling passes applied with emulsion.
  • a board cooler consists of an array of coolant or lubricant nozzles which spray a rolling emulsion onto the aluminum strip.
  • the sinker may be present in a hot rolling mill to cool rolled hot strip to rolling temperature prior to hot rolling and to achieve higher production speeds.
  • the temperature of the hot strip prior to the start of the cooling process which takes place preferably within the last two rolling passes, at least 400 ° C, preferably 470 ° C to 490 ° C, is achieved according to a next embodiment of the method that particularly small Mg 2 Si precipitates are present in the quenched hot strip, since the largest proportion of the alloying constituents magnesium and silicon are present at these temperatures in the dissolved state in the aluminum matrix.
  • This advantageous state of the hot strip is quasi "frozen" by quenching.
  • the temperature of the hot strip after the penultimate rolling pass is 290 ° C to 310 ° C. It has been found that these temperatures both allow a sufficient freezing of the precipitates and on the other hand at the same time the last pass can be carried out without problems.
