Definitions

  • the invention relates to a method and a device for cooling the copper plates of a continuous casting mold for liquid metals, in particular for liquid steel, with chill coolant guided in cooling channels and wherein during the speed ramp to target casting speed or exceeding the target casting speed or one of Kupferplatten- Target skin temperature deviating temperature, the amount or the flow rate of the coolant can be controlled.
  • EP-A-1 103 322 The initially described method and device are known from EP-A-1 103 322 for the control of the internal temperature within the die plate thickness.
  • the method referred to at the outset as known from EP 1 103 323 A2 determines an alternating copper plate temperature and corrects the mold coolant quantity and the actual casting speed by means of a computer.
  • the object of the invention is to propose specifications for a more exact control of the regulation of the controlled variables with regard to the copper plate skin temperature.
  • the stated object is achieved according to the invention in that, with changing casting speed between 1 m / min to a maximum of 12 m / min, the copper plate skin temperature by a quantitative correction of the mold coolant quantity and the mold coolant inlet temperature depending on the actual casting speed and depending on the copper plate thickness is set to a desired, constant size and that for controlling the Kokillen- coolant quantity and the Kokillenkühlstoff inlet temperature process data and system data, which are processed in controlled variables to an online simulation model, are used.
  • the copper plate skin temperature can be selected favorably even at different copper plate thicknesses and kept constant.
  • the described effects can also be achieved either completely or partially when the mold coolant is passed from top to bottom or from bottom to top through the cooling channels.
  • the continuous casting mold is oscillated.
  • the accuracy of the method can be further increased by using an immediate determination of the copper plate skin temperature in the Gblinapt Scheme addition or alternative to the online simulation model.
  • the copper plate skin temperature on the hot side already at the start of casting much lower than previously observed and the copper plate is spared in a way that the recrystallization temperature of the copper is far from reached. This advantage affects large casting speeds.
  • the mold coolant inlet can be arranged at a distance above the casting mirror.
  • the continuous casting mold is oscillated by means of an oscillating device.
  • this regulation can also be carried out in such a way that, in addition to or instead of the process computer, a device is used for determining the copper plate skin temperature in the molten metal region for controlling the mold coolant inlet temperature and / or the mold coolant quantity.
  • a continuous casting mold 1 in which liquid steel is poured, is cooled in such a way that the mold coolant 2 at the mold coolant inlet 3 is introduced into the continuous casting mold 1 in its mold coolant quantity 4 and its mold coolant temperature. Inlet temperature 5 is kept constant regardless of the casting speed 6.
  • the faults occur both from a watercourse 13.1 of the mold water 13 in the continuous casting mold 1 from bottom to top and in a watercourse 13.2 from top to bottom (see FIG. However, it can be noted that the watercourse 13.2 from top to bottom, the copper plate skin temperature 8 is lower than the watercourse 13.1 from bottom to top.
  • the continuous casting mold 1 is cooled by an inner coolant circuit 19 and an outer coolant circuit 20.
  • the outer coolant circuit 20 which runs over a heat exchanger 21, serves to cool the mold coolant 2 in the inner coolant circuit 19.
  • the inner coolant circuit 19 is guided over the heat exchanger 21 in such a way that the mold coolant quantity 4, which is set constant by means of a pump 22, is likewise kept constant in its inlet temperature 23 (T in ) independently of the casting speed 6.
  • the Kokillenkühlstoff 2 is performed as a watercourse 13.1 from bottom to top, in Dünnstranget also as watercourse 13.2 from top to bottom.
  • the coolant circuit in Fig. 1A is shown in block diagram, but with increasing casting speed 6 of 1 m / min to a maximum of 12 m / min, the copper plate skin temperature 8 by a quantitative correction of the mold coolant quantity 4 and 1 or the Kokillenkühlsch inlet temperature 5 regardless of the casting speed 6 and regardless of the copper plate thickness 9 is set at a constant controlled Kokillenkühlstoff inlet temperature 5 to a desired, constant copper plate skin temperature 8.
  • the regulation of the mold coolant quantity 4 and the mold coolant inlet temperature 5 can be achieved via a process computer 27 for an online simulation model 27.4 and process data 27.1 of the continuous casting mold 1 at a constant copper plate skin temperature 8 via an inlet speed window 6.2 (see FIG.
  • the process computer 27 requires process data 27.1 and system data 27.2 in order to control the mold coolant quantity 4 via a pump station 22.1 and / or control valves 29 and the mold coolant inlet temperature 5 through the three-way valve 24 via controlled variables 27.3.
  • a surge tank 30th Before the pump station 22.1 is a surge tank 30th
  • FIGS. 2A to 2D the procedural relationships are explained.
  • Fig. 2A shows a heat flow 17 and a profile 16 of the casting speed 6 over the casting time 18.
  • the graph describes a casting run from the start via a constant run-in speed window 6.2 with subsequent acceleration to a high speed level.
  • Fig. 2B shows the state of the art.
  • the real copper plate skin temperature 8, denoted T Cu-real increases with the casting speed 6 and deviates from the desired copper plate skin temperature 8, referred to as the target copper plate temperature 8.1, (T Cu target ) since the mold coolant quantity is 4 and the mold coolant inlet temperature 5 for cooling the continuous casting mold 1 is kept constant.
  • the real copper plate skin temperature 8 (T Cu-real ) is determined by a corresponding quantitative correction of the mold coolant quantity 4 irrespective of the casting speed 6 at a constant mold coolant inlet temperature 5 having the desired copper plate skin temperature 8, the copper plate target temperature 8.1 (T Cu target ) brought to cover.
  • the copper plate skin temperature 8 (T Cu-real ) with the target copper plate temperature 8.1 (T Cu target ) is determined by the corresponding quantitative adjustment of the mold coolant quantity 4 and the mold coolant inlet temperature 5 as a function of the profile 16 the casting speed 6 over the casting time 18 brought to coincide.
  • the inlet velocity windows 6.2 with respect to the casting speed 6 are for a desired, real copper plate skin temperature 8 at a given copper plate thickness 9 greater than in the case of variation of only one of the two influencing variables.
  • Fig. 3 the difference of the known method for the invention can be clearly read. It is the copper plate skin temperature 8 in response to the increasing casting speed 6, the max. 12 m / min., Based on.
  • a horizontal straight line of the recrystallization temperature 12 represents the end of the heat load of the copper plate made of cold-rolled copper, at which the copper loses its strength and / or cold rolling structure and thus its properties important for the casting of molten steel.
  • the temperature curve 14 in the prior art is described with the curve 14.1 (water flow from bottom to top) and the curve 14.2 (water flow from top to bottom).
  • the strongly increasing behavior of the copper plate skin temperature 8 in the casting mirror with increasing casting speed 6 and increasing copper plate thickness 9 is due to the constant in the prior art casting molds Kokillen- 4 and the constant Kokillenkühtmittet inlet temperature 5 at mold coolant inlet 3.
  • the principle of the invention can also be applied to strip casters operating at up to 100 m / min casting speed. In this case, all measures applied to the height of the continuous casting mold 1 are applied to the circumference of the twin rolls.
