- the energy content influences ⁇ for the considered rolling stock point 13 are determined immediately, ie immediately after the determination of the desired energy content profile E *.
- step S6 only the step S7 can be skipped in the NO branch.
- step S8 may be modified in such a way that in each case only the next energy content influencing ⁇ (or the next group of such influences ⁇ ) for the considered rolling stock point 13 is determined.
- at ⁇ play by applying the respective influences on the considered ⁇ Walzgut Vietnamese 13 subsequent energy gieinhaltbeeinlungen ⁇ for the considered Walzgutddling 13 nachkorrigiert.

If the considered rolling stock point 13 is located in front of the predetermined location P, the corresponding energy influencing ⁇ has been determined otherwise, for example when the considered rolling stock point 13 enters the finishing train 2 on the basis of the initial value T1 for the energy content.
- the energy influencing ⁇ he ⁇ determined in step S8 is consulted.
- the intermediate stand cooling devices 5, which are arranged downstream of the predetermined location P in the embodiment of FIG. 1, and the cooling devices 8 of the cooling section 2 are thus controlled by the control computer 10 in accordance with the energy content influences ⁇ determined in step S8.
- the predetermined location P seen in the direction x is immediately behind the finishing train 1 or between the last intercooler 5 and the last mill stand 3 of the finishing train 1, of course, only the cooling means 8 of the cooling section 2 corresponding to those in step S8 determined energy content influences ⁇ controlled.
- interstand cooling devices 5 situated in front of the predetermined location P - if present - are activated.
- the influence of the respective interstand cooling means 5 on the Energy content of Walzguta 13 are taken into account in the modeling.
- these interstand cooling devices 5 are inactive.
- the intermediate stand cooling devices 5 arranged in front of the predetermined location P do not cool the flat rolling stock 4 in this case.
- a step S10 the control computer 10 checks whether the considered rolling stock point 13 has run out of the cooling section 2. If this is the case, the procedure according to the invention for the considered rolling stock point 13 is ended.
- the flat rolling is rolled 4 d in the one Walzge ⁇ Jost 3, which is the predetermined location P as seen in the running direction x immediately upstream to a final rolled thickness.
- the final roll thickness d can be, for example, between 5 mm and 30 mm.
- the flat rolling stock 4 is no longer rolled. If the rolling mill 3 are arranged downstream of the predetermined location P, the flat rolling stock 4 is therefore no longer rolled there.
- the final rolling thickness d rather remains perpetually in its ⁇ changes.
- the downstream rolling stands 3 can be ascended so that their rollers 16 do not contact the flat rolling stock 4. This is shown in FIG 3 for the rolling mill 3 immediately following the predetermined location P so.
- the rollers 16 of the downstream rolling stands 3 are employed on the flat rolling stock 4, but not wal ⁇ zen, but drive it only without deformation. This is shown in FIG 3 for the last mill stand 3 of the finishing train 1 so Darge ⁇ . -
- a temperature measuring station 7 can be arranged between the finishing train 1 and the cooling section 2, by means of which the actual surface temperature TO of the rolling stock points 13 can be detected at the location of the temperature measuring station 7. If the temperature measuring station 7 is present, various approaches are possible.
- the corresponding surface temperatures TO are not recorded at all. This is indicated in FIG. 4 by the dashed line provided with the reference numeral 17. In this case, although the temperature measuring station 7 is present, it is not actively operated.
- step S8 is followed by a step S21.
- step S21 the control computer 10 checks whether the reserved agreed place P directly downstream Eisengerüstkühl- device 5 with respect to the considered Walzgut Vietnamese 13 with at least 80% of its maximum possible Energyinhaltbe ⁇ influencing and / or with a maximum of 90% or a maximum of 95% of their maximum possible influence of energy content is operated. If this is not the case, the control computer 10 in the embodiment of FIG. 5 proceeds to a step S22. In step S22, the control computer 10 varies the target energy content course E * accordingly.
- steps S26 and S27 may be present.
- step S26 bil ⁇ det the control computer 10, the difference between a desired Endwalzenergyinhalt T2 * and the energy content ge ⁇ Gurss the expected value T2, which is determined for the considered Walzgutddling 13 at the predetermined position P.
- step S27 the control computer 10 uses this difference to determine control variables for rolling stands 3 and / or interstand cooling devices 5, which are arranged upstream of the predetermined location P. For example, according to a control subject to deadtime, the energy content influences ⁇ for the predetermined location P upstream intermediate structure cooling devices 5 can be readjusted or a mass flow, which of course acts on the entire hot strip line, can be tracked.
- Insbeson ⁇ particular can be made by the inventive procedure in a hot strip mill for both rough sheet and for generating a band pipe grades.
