摘要:
The invention relates to a strip (4) comprising a strip head (10) and a strip leg (11). It is rolled, beginning at the strip head (10), in a roll stand (1) of a rolling device between an upper and a lower roller arrangement (2, 3) of the roll stand (1). It is monitored whether the strip foot (11) reaches a switching point (12) located, viewed in the rolling direction (x), in front of the roll stand (1). From the time the strip leg (11) reaches the switching point (12), the roller arrangements (2, 3) are subjected to a bending force (F) expanding the roller arrangements (2, 3) by means of an adjusting device (5), the force being at least as high as a minimal force. The minimal force is at least as high as a balancing force of the upper roller arrangement (2). The minimal force is determined as a function of the parameters of the strip (4) and/or the operating parameters of the rolling device.

摘要:
The invention relates to a method for the open-loop and/or closed-loop control of a temperature of a hot-rolled material (40) and to a device (1) for determining a temperature of a hot-rolled material, with a detector (2) for detecting electromagnetic radiation emitted from a measuring region of the hot-rolled material (40), with an evaluation unit (3) for determining a temperature from the radiation detected. At least partial shielding of the measuring region makes it possible to provide a device for determining a temperature that has a high level of measuring accuracy while performing contactless measurement of the temperature.
