Definitions

  • the invention relates to a method for rolling steel profiles, in particular in a universal carrier rolling mill with alternating X and H rolling as well as targeted cooling of the steel profile during rolling.
  • Processes and rolling mills suitable for rolling steel profiles or beams or streets are well known, for example from EP-A-0 256 409 and EP-B-0 498 733.
  • These temperature differences call during normal or forced cooling the rolled beam to room temperature stresses in the profile, causing a Distortion and / or curvatures can occur that affect the wearer's resilience reduce.
  • These temperature differences, the or their effects on Completely rolled supports are difficult to remove, impair or place Cooling measures for tempering from the rolling heat or for thermomechanical Rolls in question.
  • Cooling devices used to date are based on immersion cooling or spray cooling, as for a procedure mentioned at the beginning by the magazine "Stahl und Eisen 109 (1989), No. 9, 10 ", pages 497 to 502
  • the process consists of a thermomechanical rolling process for heavy beam profiles from a combination of thermomechanical treatment and selective cooling the flange-web connection zone during rolling. It should be one uniform temperature distribution in the flange and thus homogeneity the material properties in the product cross section can be improved. It will be there tries the transition or connection zone flange / web either from the outside Spray on the flange side centers or from the inside and outside. Both Measures require complex cooling sections with adjustable nozzles.
  • the Cooling devices are either between the roughing stands or after arranged on the finishing stand. With tandem reversing lines on one side of the Roll stands, so that the profile or the carrier during the roughing or after the finish stitch cools.
  • the invention is therefore based on the object of a method of the beginning to create the type mentioned, with simple means and little effort a more uniform temperature across the cross section of a rolled steel profile can be reached after cooling.
  • This object is achieved in that in the roughing in an X-caliber on each side of the steel profile at the junction of the web and flange a cooling water channel is formed. It can therefore be a uniform temperature across the cross section of the beam profile at low Reach level by using no additional cooling devices - such as especially nozzle arrangements - the already existing cooling water in the Cooling water channels and thus in the area of the web / flange connection zone is concentrated, and this through the early use of cooling, namely during roughing.
  • the web is required to form the cooling water channels to be rolled only slightly buckling upwards, for which the horizontal rolls have a corresponding complementary shape in the roughing stand. It results a roof-like web configuration, i.e. with to both flange sides inclined web sections, which in interaction with the flanges form the gutter provide.
  • An embodiment of the invention provides that in the cooling water channels H-rolling effluent rolling cooling water is concentrated.
  • the available with it standing water volume ensures the desired locally stronger cooling of the rolled material in the area with a material accumulation, i.e. the connection zone between web and flange.
  • the concentrated Roller cooling water an additional amount of water either unpressurized or as Spray water is added.
  • the existing roller cooling water can thus if necessary in the form of laminar cooling or with a necessary or desired movement can be added.
  • At least one Rolling the finishing stand is disengaged from the steel profile.
  • the finishing stand for one or multiple stitches just to be opened, which is synonymous with an extended cooling effect.
  • the possible results Cooling times from the respective rolling length, the rolling speeds and the Reversing and non-productive times.
  • the Cooling times essentially determined by the number and length of the cooling sections.
  • a universal roughing stand I and a universal finishing stand II comprehensive rolling mill is an H-beam 1 (dimensions 600 x 300 mm) produced by X-H rolling in several passes.
  • the upsetting roller arrangement of the universal roughing stand I, with which the X-rolling is carried out, consists of two vertical rollers 3 and two acting on the carrier flanges 2 the carrier web 4 acting horizontal rollers 5.
  • the roller arrangement of the Universal finishing stand II for H-rolling the beam 1 also has two Vertical rollers 6 and two horizontal rollers 7; in a last stitch there is the final H-beam 1 completed.
  • the lower horizontal roller 5 is slightly double-conical, that your bale tapers from the central plane to the roll neck, while the upper horizontal roller 5 has a complementary, incised roller contour having.
  • the carrier web 4 therefore takes a roof-like in the X-rolling Configuration with web sections 4a or inclined towards both carrier flanges 2 4b. It is achieved in this way that in the transition zone low-lying ends of the web sections 4a and 4b to the support flanges 2 both on the left and on the right side a cooling water channel 8a or 8b trains.
  • This can preferably be that of the H-roller arrangement of the Concentrate the universal finishing stand II draining roller cooling water and the Cool the H-beam 1 more strongly in this area with a larger material accumulation.
  • the formation of the cooling water channels 8a and 8b and - if necessary by Supplementary additional water supply - amount of cooling water can be in Dependency of the rolling cycles should be such that a uniform Temperature over the cross section of the rolled carrier is reached. This helps also in that - as in FIGS. 2 and 3 for the left cooling water channel 8a shown - during the flange plunge stitch without touching the web (see FIG. 2) or with upset rollers placed on the web 4 (cf. FIG. 3), which is characterized by Can influence the contact surfaces of the compression stand, is rolled. In case of a X-H tandem reversing line inevitably follows that always on the The inlet and outlet side of the universal roughing stand is cooled with X calibration.
