Definitions

  • the invention is based on the object to provide a method and an apparatus with which a minimization to complete avoidance of the strip tension of a rolling stock between two successive rolling units is possible in a simple manner.
  • the roller table forms a support for the rolled material loop in at least one off-center section of the track section, the support line of the roller table corresponding to the free deflection in this section of the chain line.
  • the roller table segment 30 is lowered down, so that in the sink 26 a rolling stock loop 6 is formed.
  • the loop depth 18 of this rolled material loop 6 is controlled so that it corresponds to the free deflection in the section 27. Under free deflection is to be understood as the deflection of a both sides freely cut portion of the rolling stock 1, which rests each end without friction.
  • FIG. 8 a further embodiment of the device according to the invention is outlined.
  • the recess in the transport plane is formed here by sections 31 of the roller table, which are each pivotable about the axes 32 by means of the adjusting device 29 downwards.
  • the speed of the rollers of the drivers 3, 8 is precisely controlled by the control device 10 so that the stationary mass flow is kept constant, but temporary fluctuations are absorbed by the loop-shaped formation of the hot strip 1.
  • the hot strip 1 is either on all rollers 9 of the roller table 5 touching, or is slightly lifted in a central region 11 of the sink 26 of the supporting roles by there is formed by speed control of the rolling mill main drives or the driver roller drives a gravitational loop.
