Definitions

  • the straightening method according to the invention builds on the basic idea to direct the profiles at profile temperatures of> 70 ° C in such a way that the straightening force is introduced directly into the flange of the profile. As a result, residual stresses in the profile are avoided, which otherwise produce deformations of the profile during cooling.
  • profiles are directed with a web and at least one flange.
  • profiles are in particular T-beam, double T-beam, U-profiles and L-shaped profile legs, wherein the Flange in all profile types is preferably at an angle of 90 ° to the web, although other orientations are readily possible.
  • the profiles are directed at profile temperatures of over 70 ° C, more preferably at temperatures above 100 ° C.
  • the method according to the invention also makes it possible to straighten at higher temperatures, for example also at about 200 ° C. and more.
  • the term profile temperature may include, for example, the stem root surface temperature as well as the temperature in the stem root.
  • it can also comprise the surface temperature of the web as well as the carrier edges or the temperature in these profile elements.
  • the profile temperature can also be determined by including the temperature of several of these profile elements.
  • the profile temperature can be determined by measuring the temperature profile in the entire profile or by measuring the temperature in some of the profile elements.
