  • the invention relates to a method for applying a coolant to a rolling stock and / or to at least one work roll of a roll stand having a roll gap, wherein the rolled stock is rolled with the aid of the roll stand. Furthermore, the invention also relates to a rolling stand.
  • coolant usually oil or oil emulsion
  • oil or oil emulsion is used to cool the rolling stock and / or the rolls of a roll stand.
  • the rolling gap of the roll stand is lubricated by oil or oil emulsion.
  • the coolant can thus even or in extreme cases even serve exclusively as a lubricant.
  • D3 discloses spray nozzles with which a cooling liquid is applied to the upper work roll of a rolling stand.
  • the object of the invention is to apply a coolant to a rolling stock and / or to at least one work roll of a roll stand such that the most constant and stable cooling or lubricating conditions are ensured.
  • This object is achieved by a method for applying a coolant to a rolling stock and / or at least one work roll of a roll stand having a roll gap, wherein the rolling stock is rolled with the aid of the roll stand, and wherein the amount of coolant to be applied as a function of effective in the roll gap Performance is determined, wherein the effective power in the nip of the performance of the at least one drive of the rolling mill, plus the output in the outlet run of the roll stand, less the power in the inlet run of the roll stand composed. In this way disturbing thickness influences are minimized and excessive belt or roller temperatures are avoided.
  • the amount of coolant to be applied can be determined in proportion to the effective power in the nip.
  • the flatness of the rolling stock can be determined over a plurality of zones in the width direction, wherein the coolant is applied as a function of the determined flatness distribution distributed over the plurality of zones on the rolling stock and / or on the at least one work roll.

  • the rolling stock 1 passes through the roll stand 2 in the longitudinal direction x.
  • the rolling stand 2 has a plurality of work rolls 3, which extend in the width direction y and are arranged substantially one above the other. Between the work rolls 3 is the nip 9, which passes through the rolling stock 1 during the rolling process.
  • cooling nozzles 5 are arranged, which are directed to one or more of the work rolls 3 and / or on the rolling stock 1.
  • the cooling nozzles 5 are used to apply coolant 8 to the rolling stock 1 and / or to the work rolls 3. Especially during cold rolling, the rolls 3, 4 and the rolling stock 1 can be cooled with so-called rolling oil as the coolant 8.
  • the rolling oil serves at the same time to lubricate the nip 9.
  • the coolant 8 may have an oil emulsion.
  • the coolant 8 may at least partially consist of water.
  • the rolling stand 2 and the rolling stock 1 therein are supplied by at least one drive not shown in the drawing energy. Much of this Energy is dissipated with the moving, heated rolling stock 1 and via the coolant 8, in particular the rolling oil.
  • the distribution of the discharged energy to the rolling stock 1 and the coolant 8 depends on various circumstances, such as the type of material to be rolled, material hardness, deformation resistance and speed of the rolling stock 1 from.
  • the cooling nozzles 5 are preferably on one or more beams 10 (see FIG. 2 , in FIG. 1 not shown in detail) arranged.
  • a roll stand 2 On a roll stand 2 are preferably per work roll 3, one to three bars 10 for cooling and optionally additionally provided a further beam 10 for lubrication.

  • arrangement can be easily transferred in reverse to a arranged below the rolling stock 1 cooling system with cooling nozzles 5 and at least one beam 10.
  • FIG. 3 shows the distribution of the zones 11 relative to the rolling stock 1.
  • the rolling stock 1 is shown in plan view.
  • the necessary total amount of cooling for cooling in the rolling stand 2 is determined as a function of the effective power in the nip 9.
  • the necessary total amount of cooling can be determined proportional to the effective power in the nip 9.
  • the effective power in the nip 9 is composed of the power of the at least one drive of the roll stand 2, plus the output in the run-out of the roll stand 2, minus the power in the intake run of the roll stand 2.
  • the resulting performance in the nip 9 is in work of deformation and thus in Heat converted.
  • the effective power in the nip 9 is determined in the speed control of the rolling stock to be rolled 1 effective drives.

  • cooling nozzles 5 are each associated with zones 11, wherein each zone 11 at least one, preferably exactly one cooling nozzle 5 is provided.
  • a total quantity regulator of the multi-zone cooling control is superimposed, which ensures that the required total cooling quantity is set by increasing or decreasing the amount of cooling in the individual zones 11 of the cooling. This ensures that the required total amount of cooling is kept as constant as possible under constant conditions. In this way, it is avoided that the rolling stock 1 and the rolls 3, 4, in particular the working rolls 3, heat excessively.
  • the adjustment of the cooling amount for each individual zone 11 of the cooling takes place by determining the on-off-time ratio of the cooling valve of the corresponding cooling nozzle 5 or by a proportional valve.
  • the total cooling quantity CS resulting from the flatness measurement or from the flatness control is compared with the predetermined total cooling quantity VS.
  • the predetermined total amount of cooling VS is preferably determined as described above as an example depending on the effective power in the nip. From the resulting total cooling amount difference SD becomes calculated additional cooling component Ca for the individual cooling nozzles 5 and zones 11. This takes into account that a minimum or maximum cooling amount per zone 11 can not be fallen below or exceeded, and that different zone widths b 1 , b 2 (see FIG. 2 ) condition different coolant flow rates. A distinction is made between missing quantities of cooling components mk with respect to zones 11 of large width b 1 and excess quantities of cooling components mg relative to zones of large width b 1 .
  • the excess cooling proportions mg based on zones 11 of large width b 1 are subtracted from the total cooling amount fractions mz relative to zones 11 of large width b 1 in order to determine the additional cooling amount fraction Ca for the individual cooling nozzles 5.
  • This additional amount of cooling Ca is now not directly on the cooling volume distribution C Z added, but converted into a control deviation r and added to the controller output of each zone 11.
  • the comparison of the total amount of cooling CS with the predetermined total amount of cooling VS and the resulting correction of the controller output is repeated until the difference between the total amount of cooling CS and the predetermined total amount of cooling VS falls below a predefinable value.
  • the invention relates to a method for applying a coolant 8 to a rolling stock 1 and / or at least one roller 3, 4 of a roll stand 2 with a nip 9.
  • a total amount of cooling to be applied is first determined as a function of the effective power in the nip 9.
  • cooling quantities for a plurality of zones 11 are determined as a function of the deviation of the flatness distribution determined by means of a flatness measuring system 6, wherein a cooling quantity difference is determined by comparing the sum of the thus determined cooling quantities with the previously determined total cooling quantity, on the basis of which additional cooling quantity components for the zones 11 taking into account upper - And lower limits of the cooling quantities for the zones 11 are determined.
