  • HTS motor both a machine whose rotor winding is superconducting and whose stator winding is normally conducting, and a machine, so-called fully superconducting machines, in which both the rotor and the stator winding is made using superconducting material to understand.
  • the rolling stands in a rolling mill due to the spatial extent of rolling stand, gear and electric motors must comply with a minimum distance, the minimum distance of the rolling stands is due to the Size of the frame stand, of possibly necessary Eisengerüsttransport adopteden limited by electric motors or transmission.
  • rolling stands which are driven by a HTS motor, the minimum distance between immediately adjacent rolling stands and thus, for example, the unwanted cooling of the rolling stock can be reduced by reduced thermal radiation.
  • HTS motors which have a much smaller size with the same power compared to conventional electric motors.
  • HTS motors which have a much smaller size with the same power compared to conventional electric motors.
  • the use of a HTS motor in a rolling mill considerable energy savings (lower power dissipation) and because of possible reduced aggregate distances also brings cost advantages. This is particularly advantageous in cast-rolled composite systems.

  • the rolling stand can be designed, for example, as a duo or as a quarto-rolling mill or as a hexagonal rolling mill.
  • the rolling mill is driven by a more compact HTS motor with the same power, the distances between the rolling stands can be selected smaller and the entire rolling train can be made shorter or more compact.
  • the inventors have recognized that use of an HTS motor in the rolling mill thus brings with it significant cost reductions as well as technological advantages as a result of reduced cooling of the continuous rolling stock.
  • An HTS engine has a more stable, stiff performance (e.g., small rotor angle) and also reacts faster to changes in command values than a conventional electric motor. This case occurs frequently during rolling. In comparison to a conventional electric motor, an HTS motor is thus able to be regulated more quickly, which allows an improved and / or faster puncture behavior and / or an improved ski control particularly when it is used in a rolling train. This is particularly advantageous in heavy hot rolling reversing lines. As a "ski” is an unintentional deformation of the band up or down, i. referred to perpendicular to the transport direction.

  • the rolling stand is configured such that it comprises a plurality of HTS motors, wherein each of the work rolls - preferably as described above directly or with a reduced gearbox - is mechanically connected to the shaft of one of the HTS motors. Since compared to conventional electric motors, the HTS motors with the same torque have a smaller size, eg due to a smaller stator diameter, the distance between the drive shafts of the motors can be reduced to each other.
  • the electric motors are arranged directly next to one another or locally above one another (offset from each other). According to a further embodiment, these therefore advantageously have a common cooling system.
  • an HTS motor is not only advantageous in directly driven rolling stands, such as the aforementioned twin drives, but also in a rolling mill, which according to a further embodiment comprises two work rolls, which are mechanically coupled via a branching gear, said this drive side with the shaft of one of the electric motors is coupled.

  • the stand spacing of today's hot rolling mills in conventional construction is typically more than 5.0 m to 5.5 m.
  • the rolling stock may, for example, cool down too much between the individual rolling passes or form scales on the surface.
  • additional equipment such as an induction furnace or a descaling unit be compensated.
  • the use of such additional units and their integration in the rolling mill is expensive on the one hand and resource-intensive on the other hand.
