Definitions

  • the invention relates to a working method for XH rolling of parallel-flanged steel profiles (trusses) with H-profile in tandem operation in one Compact rolling group consisting of a first universal scaffolding, this one downstream upsetting frame and a following, second universal frame consists, with the rollers of the frameworks inclined, respectively vertical to the axes of the Rolls extending rolling surfaces.
  • the invention is based on the object, the wear of the horizontal rollers reduce, for both scaffolds to coordinate and as equal as possible hold.
  • This object is achieved in that when using vertical rollers with, between 0 degrees and 10 degrees away from each other inclined rolling surfaces in the first Universal scaffolding and vertical rolls with cylindrical rolling surfaces in the second Universal scaffolding, the side surfaces of the horizontal rolls, with the roll surfaces the vertical rolls form the H caliber, slopes of 0.0 degrees to 0.5 degrees in each case in the second universal stand a reduction of To produce rolling stock, the 0 - 100% of the achieved in the first universal scaffolding Decrease is.
  • the outer bale length of the horizontal rollers of the second universal stand can thereby advantageously correspond to the chamber internal dimension of the H-beam to be rolled.
  • the use of the work procedure could be reduced of 100% of the decrease in the first universal scaffold in the following passes cascade to the last stitch with a minimum of 5%. But it can too be beneficial, for reasons of temperature conditions a passage with very to drive a small decrease in the two universal scaffolding, then the Decrease in scaffolding then increase again.
  • the application of the working method according to the invention makes it possible for the necessary rewinding of the rolls of both Universaigerüste a simultaneous and thus cost-effective time to determine and by this vote also to reduce the material losses and thus the total production costs.
