Definitions

  • the invention relates to a compact rolling mill for rolling shaped steel on rolling stands arranged in a plurality of rolling lines, such as universal rolling stands and duo rolling stands with longitudinal and transverse conveying devices and guide devices for the rolling stock along a rolling line or from one rolling line to another, and working methods for Rolling with this rolling mill.
  • Compact rolling mills of this type should, unlike large, extraordinary investment costs and a lot of space, in particular profile roller mills requiring length, on which only one profile program can be rolled economically with correspondingly high production, should enable the possibility of a very wide profile program on a single rolling mill , which also includes beams, rails and sheet piles, can be economically rolled even in smaller production quantities.
  • duo mill stands also proposed to expand a production program in such rolling mills also entails a considerable additional space requirement in addition to the investment costs that are required for this and requires corresponding increases in the production of at least certain profiles if the overall profile program is to be produced economically.
  • the invention has for its object to provide a compact rolling mill for rolling shaped steel, in which the above-mentioned disadvantages and difficulties are avoided or eliminated and the rolling of a very wide profile program is possible with less space requirement for the rolling mill and smaller investment costs.

  • the drive shafts of the roll stands can have hit sleeves and / or rod ends axially displaceable on the roll side.
  • continuous casting cross-sections can be adapted without the use of a duo roughing stand or continuous casting cross-sections can be adapted first by means of an assigned duo vertical upsetting stand and then fed directly to the universal rolling.
  • stands are advantageously suitable that allow the roller sets to be lifted upwards.
  • the design of the compact rolling mill according to the invention also allows existing rolling mills to be converted and expanded step by step to the arrangement according to the invention, thus enabling the rolling of a considerably wider profile program.

  • carriers can are rolled in such a way that all pass passes including the guide pass when the drive is disconnected from all other roll stands are carried out on the universal tandem compact stand group in the main rolling line.
  • the compact rolling mill can be used for this purpose Profile rolling, especially of sheet piles, the individual rolling steps consist in the fact that the first heavy form passes reversing on the universal rolling stand and the duo compression stand remaining in the main rolling line, the following form passes on the universal stand placed in the third rolling line, the duo located there Compression mill, and the finishing stitches are carried out continuously in succession on the permanently calibrated three duo mill stands in the second rolling line.
