Definitions

  • the invention relates to a method for rolling finished profiles from pre-profiles by means of working in reverse operation Roll stand arrangements, one of which, a compact rolling group, consisting of a first universal scaffold and an output-side second universal scaffold and one, between represents these intermediate scaffolds arranged intermediate compression scaffold, the one, from vertical and horizontal rolling stands and / or Universal mill stands prior to the pre-rolling group.
  • Rolling sheet piling and angle profiles and similar profiles has been used consistently in fully continuous roller mills performed, the variety of for roughing such profiles necessary shape calibers when reversing large Roll stands with large variety of shape calibers Bale lengths of the rollers required.
  • These big scaffolds and that Rolls themselves, as well as the necessary manipulation devices for the introduction of the rolling stock into the different calibers is very complex, require a large amount of space and are proportionate low throughput.
  • the large quantities of the rolling stock even lead to relatively long rolling times reversing rollers and therefore practically do not allow such plants in a work cycle sequence with a continuous caster to operate. It is therefore in a network between Continuous casting plant and rolling plant relatively large intermediate storage necessary.
  • the invention has for its object the rolling of sheet piling and Angle profiles, as well as other comparable profiles with the help the generic basic training of mill stand arrangements carry out and as starting products either continuously cast Rectangular blocks or already in one of the end product as possible approximate preform to use cast pre-profiles.
