Definitions

  • the invention relates to a method for continuous according to the preamble of claim 1 Production of finished metal profiles with a Rolled structure, in particular geometrically complex profiles such z.
  • a continuously cast Continuous strand with a cast structure without subdivision and interim heating a rolling mill, in particular universal rolling mill is supplied.
  • the invention relates to a Oberbrgiff of claim 4 Arrangement for carrying out the method.
  • a casting wheel As a casting machine, a casting wheel is used.
  • the one in trapezoider Form the strand leaving the casting wheel is from a water cooled scraper lifted out of the wheel and the Bending zone and supplied to the straightening driver.
  • the casting area is followed by the cooling area which, as a open spray cooling is performed to the liquid residue sump solidified in the strand in a controlled manner.
  • the cooling joins a compensation zone, by a in the Speed adjustable roller table is realized, the the strand passes through without additional cooling and on the a heat balance takes place in the strand.
  • the subsequent rolling area consists of two rolling stands, in which the strand is rolled to dimension, which in a further processing rolling mill, for example one Promenade, let insert.
  • the task is based, a method and an arrangement of initially mentioned type for the production of insbeondere geometrically complex profiles such as beams, sheet piles, railway rails and railway construction material etc. with improved economy, especially through less Malfunction, higher material output, lower Energy costs and less design effort propose.
  • the cross section of the cast Stands By changing the mold, the cross section of the cast Stands to a variety of different finished profiles be approximated, with the above give beneficial effects.
  • Another advantage of the Continuous casting rolls result in almost during rolling no headboards and feet with dangerous sharp tongues occur at bridge and flanges. After rolling it will Prefabricated profile fed to a cooling section and then with Help a running subdivision device in sections divided, whose length is a multiple of the length of the sellable subdivided finished profiles amounts.
  • the Continuous casting rolls allows both upstream and downstream also in downstream areas of the arrangement for Performing the procedure slows down the deployment Machines, in particular band saws for dividing up Sales lengths.
  • the cooling is preferably carried out with a Water-air cooling section.
  • the liquid steel area shown on the left in the picture consists of a pan 1, a tundish 2 and a casting wheel 3.
  • the arranged under the pan 1 Tundish has the task, the Align pouring stream on the mold of the casting wheel 3 and serves as a buffer during the pan change.
  • That too known casting wheel 3 comprises an endless circumferential Steel chain, scraper and cleaning accessories and coolant.
  • the steel chain closes a groove approximately on one Quarter of the wheel circumference of the casting wheel 3 and forms with the Wheel the mold.
  • the steel runs from Tundish 2 into the mold and solidifies during the quarter turn of the casting wheel 3 so far, that a solid shell has formed.
  • This semi-solid strand is in a downstream Arrangement 4 descaled and immediately several, in the embodiment four roll mills 5 fed, the off the thin close to the final profile of the mold, the Finished profile is geometrically similar, for example a Form double-T beams.
  • Compared to conventional reversing mills usual 10 m / s, this is despite the high casting speed a very small rolling speed.
  • Under the example given process data results in 6000 operating hours per year one year production output of 1,440,000 tons.
  • a downstream water-air cooling section 6 is the Walzwarme profile cooled down to ambient temperature, where with the regulation of the cooling curve the residual stresses, the Structure education, the surface texture and the Straightness of the profile during further cooling targeted to be influenced.
  • the low rolling speed of the profile rolling stands 5 allowed the subdivision of the continuously produced finished profile with a revolving saw 7 in sections, the by means of a cross conveyor 8 with integrated therein Streckrichtstrom 9 a stacking system 10 for forming single or multi-layer layers (packets) supplied to the sections become. From the stacking system 10 get the packages via a roller table 11 to another sub-device 12. The packages have a total weight of about 30 t. Consequently The cycle times can be used to divide the sections in ready to sell finished profiles in the other sub-device 12 are chosen large, so that slowly running machines, such as band saws, for dividing come into question.
