Definitions

  • the invention relates to a rolling mill for hot rolling of metal, in particular of aluminum, with a hot strip mill with a roughing mill and a finishing train and a corresponding hot rolling process.
  • An apparatus and a method according to the preambles of claims 1 and 4 are made US-A-5,931,040 known.
  • An aluminum ingot 117 is brought to rolling temperature in furnaces 120, 121-for example hearth or pusher furnaces-and pre-rolled in the single-stand roughing stand 108 of the roughing train 104 after passing through an upsetting stand 107.
  • the rough-rolling product is interspersed with a first scissors 122.
  • the board 119 is pimped at the end and end of the board, between these two cropping shears 122, 125 a certain distance is present.
  • the finish-rolled strip 113 in the finish rolling mill runs along edgers 126 and is reeled up by means of drive rollers 127 from a reeling device 114.
  • Such a plant with furnace area 102 and rolling mills 103 can have enormous lengths.
  • the length x of a furnace area 102 may be 130 m
  • the distance between the roughing stand 108 and the first stand 111 of the finishing train may be 240 m, for example, the distances influencing the achievable coil sizes.
  • the run takes place of the rolling stock through the rolling mill plant with the help of extensive transport and leadership facilities, such as roller tables.
  • Such rolling mills tend to work more economically with larger coil dimensions.
  • the basic idea of the invention is that the compact construction of the rolling mill or of the hot strip mill is created jointly by the consistent use of tandem rolling in the rough rolling mill, in the finishing train or in the rough rolling mill and finishing train.
  • the roughing train alone and / or the finishing train alone or the roughing and finishing train together are tandem mills, ie plant sections in which the mills stand in tandem (tandem arrangement). Due to the resulting compact construction significant parts of the otherwise necessary roller tables can be omitted, thereby reducing the investment costs.
  • the proposed layout is not only suitable for new buildings, but also for modernization of existing plants.
  • it is achieved by tandem rolling in the roughing and / or finishing mill that smaller plants on which previously only smaller tonnages and smaller coils were produced, their further processing is partially uneconomical, can be converted so that the length of the roller tables remains the same Bund weights (tape lengths) can be increased, which increases productivity.
  • Fig. 1 shows the new compact hot rolling mill layout 1 for aluminum.
  • the comparison with the layout 100 according to the prior art according to Fig. 3 illustrates the compactness of the system according to the invention.
  • the plant also consists of a furnace area 2 and the rolling mill 3 with a roughing and a finishing train (4, 5).
