    • SUBJECT OF THE INVENTION
  • The subject of Claims 1, 8 and 12 represents a device for production of flat metal. By the rolling device, the metal is rolled flat to an adjusted thickness, then the flat metal is subjected to current and voltage in the device for heat treatment. This makes possible the attainment of an exactly defined strength class for the flat metal. Then the heat-treated flat metal strip is wound on a reel, by corresponding displacement and rotation of the reel.
  • The term “flat metal” here refers in particular to strips of metal sheet and metal film, in particular to rolls of wound material. Especially a thickness range from 20 to 400 μ is relevant.
  • Claims 14, 18 and 21 define the process of production according to the invention, and Claims 1, 8 and 12 the corresponding means of production. Other advantageous embodiments are to be found in the subsidiary claims.
    • FIGURES
  • The following description deals with possibilities for conformation of the invention. These possibilities are to be understood by way of example only, and are presented with reference to:
  • FIG. 1. A view of the production device, with its three units, rolling, heat treating and winding.
    • DESCRIPTION OF THE INVENTION
  • FIG. 1 shows the device for production of flat metal, with its three units: rolling (1), heat treatment (13) and winding (16).
  • Flat metal (10) here refers in particular to strips of sheet metal and metal film, in particular material wound in rolls. Here a thickness range from 20 to 400 μ is particularly relevant.
  • The flat metal (10) is rolled in the rolling device (1) by at least two parallel rolls (2, 3) arranged parallel to each other, to the adjusted thickness. The axes of rotation (4) of the rolls lie in a plane; the rolls themselves are arranged horizontally.
  • The setting and adjustment of the desired thickness is accomplished by precision thread drives (8) with exact guidance (8).
  • These precision thread drives (8) ensure a setting in the 100th mm range.
  • The cooling liquid in the trough (20) under the rolls, optionally in combination with emulsion, ensures that the rolls (2, 3) can be kept continually at constant temperature, so that no heat expansion occurs that would adversely affect the precision of the rolling operation.
  • One of the rolls (2) is adjustable by means of the above precision feed (8), the other roll (3) has a fixed bearing seat.
  • The rolls (2, 3) of the pair must always both be driven.
  • The flat metal (10) is fed in (11) and taken out (12) free from tensile stress.
  • After rolling, the flat metal passes by way of two rolls (12, 14) configured with electrically conductive surface.
  • The flat metal (10) is subjected to current and voltage by means of these.
  • By this application of current and voltage, the flat metal (10) is heated and its strength altered.
  • The quantity of current is regulated as a function of the system's speed so that the flat metal (10) receives a constant strength corresponding to the desired strength class.
  • After the heat treatment, the flat metal is wound on a reel (17).
  • The axis of rotation (18) of the reel is more or less perpendicular to the direction of entry of the flat metal.
  • By a roller ring drive (19), the reel is run to and fro along its axis of rotation to ensure placement of the flat metal on the reel.
