Definitions

  • the present invention relates to continuous casting, preferably semi-continuous, continuous casting of a metallic strand in a continuous casting machine.
  • the generic method and a suitable system are from WO 2015/079071 known.
  • the cooling rate of the strand can be fine-tuned from bottom to top.
  • the formation of cavities in the strand is prevented, so that liquid molten steel can compensate for the solidification-induced volume jumps between the solid and liquid phase.
  • the internal quality of the strand is thereby significantly improved. How the inner quality of the strand can be further improved, is not apparent from the Scriptures.
  • the object of the invention is to modify known continuous casting processes so that cavities or cracks in the strand are prevented even more consistently. This should further improve the internal quality of the cast strand.
  • the solution is carried out by a generic method, wherein the strand is thermally insulated in the Tertiärksselzone by a thermal insulation and a heat transfer coefficient U of the heat insulation in the casting direction is increasingly adjusted.
  • the heat insulation can either be preset statically or set dynamically during casting or solidification.
  • a strand typically a steel strand or a strand of a so-called superalloy (see https://de.wikipedia.org/wiki/Superleg réelle, for example, a nickel-based alloy), produced with a pronounced V-shaped configuration of the strand shells.
  • forms in the Tertiärksselzone a strand whose strand shell is much thicker at the beginning of the strand than at the strand end.
  • liquid molten steel can directly fill up any voids caused by the solidification, which improves the internal quality of the strand.
  • a simple way to achieve a heat transfer coefficient U of the heat insulation, which increases in the casting direction, is to make a thickness of the U of the heat insulation in the casting direction decreasing.
  • a heat transfer coefficient U of the heat insulation which increases in the casting direction can also be achieved by decreasing the degree of coverage of the heat insulation of the surface of the strand in the casting direction. This can e.g. be done by insulation panels whose degree of coverage is preset statically or dynamically adjusted during casting.
  • the tertiary cooling zone comprises a plurality of dynamically adjustable during operation Isolierpanele, wherein an opening angle an insulating panel relative to the vertical in the casting direction is increasingly adjusted.
  • the increase is piecewise continuous, preferably continuously differentiable at least once. As a result, shocks are prevented in the continuous casting machine.
  • the calculation of the actual temperature field is eg from the DE 4417808 C3 or the WO 2009/141205 A1 known. Details are included in this application by reference.
  • the heat insulation can be adjusted, for example, so that the actual position of a time-dependent desired position of the sump tip corresponds as possible.
  • an intensity of the secondary cooling is advantageous to set as a function of the actual temperature field and / or the actual phase boundaries, in particular the actual position of the sump tip.
  • a further improvement in the internal quality of the strand can be achieved if the continuous casting machine comprises a strand-movable in the casting direction, the strand agitator during the extraction and after completing the extraction of the cold strand from the mold, the region of the sump tip of the strand is electromagnetically stirred.
  • the solution is carried out by a generic continuous casting machine, which has a control or regulating device for controlling or regulating a heat transfer coefficient U of the heat insulation in the Tertiärkühlzone.
  • control or regulating device realizes a time or length-dependent control or regulation of the heat transfer coefficient U.
  • an extraction speed of the strand from the mold and / or an intensity of the secondary cooling can be set as a function of the actual temperature field and / or the actual phase boundaries, in particular the actual position of the sump tip.
  • FIGS. 1a ... 1h is the continuous casting, specifically the so-called semi-continuous continuous casting, a strand 1 shown in steel.
  • the continuous casting machine is designed as a vertical installation and has as main components a water-cooled mold 2, a strand guide 3 comprising a plurality of strand guide rollers 3a engageable with the strand 1 and a secondary cooling 4 with a plurality of cooling nozzles 4a and a tertiary cooling zone 5 with a thermal insulation 9 and several insulation panels 9a on.
  • the machine head of the continuous casting machine comprising the mold 2 and the strand guide 3, are movable relative to the tertiary cooling zone 5, so that a single machine head can supply strands to several tertiary cooling zones.
  • the strand guide rollers 3a need not necessarily be adjustable via an actuator to the strand 1. It is sufficient if these can be adjusted to the strand mechanically, for example via washers or so-called shims.
  • Fig. 1a the situation is shown before casting the continuous casting machine.
  • a cold strand 6 was introduced into the mold 2, so that the stationary cold strand 6, the mold in the casting direction G fluid-tight seals.
  • In 1b is the casting of the continuous casting machine shown.
  • a molten steel or a melt of a so-called superalloy is fed into the mold 2 either directly or via a distributor vessel, so that a casting level M is formed in the mold 2 and a strand 1 due to the primary cooling of the mold 2.
  • a somewhat constant pouring M is started with the extraction of the cold strand 6 from the mold 2.
  • the drawing off takes place relatively slowly with a first drawing speed v 1 of 0.12 m / min (see Fig. 3a ).
  • the extraction speed v is increased (see Fig.
  • a thin strand shell 11 at the upper end of the strand 1c facilitates this crucial.
  • the mold 2 is oscillated by an oscillator, not shown, in the vertical direction.
  • a stirring coil, also not shown below the mold 2 stirs the partially solid strand. Both details are customary and eg from the WO 2015/079071 known.
  • Fig. 1c the continuous casting is more advanced, wherein the strand 1 is supported and guided in the strand guide 3 by the strand guide rollers 3a and further cooled by the cooling nozzles 4a of the secondary cooling 4.
  • the solid line of Fig. 3a is the extraction speed at the time of Fig. 1c in about 0.2 m / min.
  • Fig. 1d is the time in continuous casting shown, in which the supply of molten steel was just stopped in the mold.
  • the drawing speed v corresponds to the second drawing speed v 2 of 0.36 m / min. This pull-out speed of the strand 1 is maintained until the end of the pull-out operation (see Fig. 3a ).
  • the pouring mirror G in the mold 2 drops (see Fig. 1e ).
  • the strand 1 has its final strand length L of typically 6 to 12m.
  • the diameter of the strand 1 is 600 mm.
  • the Fig. 1f shows the situation after the strand end 1c has passed the strand guide 3 and the secondary cooling 4 has been switched off.
  • the partially solided strand 1b is then in the Tertiärksselzone 5 and is slowly controlled or controlled cooled.
  • the non-inventive cooling of the partially solidified strand 1b is shown in the Tertiärkssel 5, wherein the time of Fig. 1g before the time of Fig. 1h is.
  • the machine head can serve several tertiary cooling zones 5 and, for example, can be moved in a horizontal direction to a further tertiary cooling zone 5.
  • the strand end 1 c can be heated by a head heater 13.
  • the head heater 13 can be made, for example, inductively or by an exothermic powder (the process is referred to as "hot topping"), wherein the powder generates heat energy with the liquid molten steel. Since the partially solidified strand 1b in the region of the sump tip is particularly susceptible to cracks or cavities, it is advantageous if a strand agitator 14 in particular electromagnetically stirs this region.
  • the Fig. 2a shows a continuous cast semi-solid strand 1b according to the prior art.
  • the strand end is almost completely solidified, so that any voids or cracks in the strand can not be filled by liquid melt 12.
  • FIG. 2b shows a strand of the invention.
  • the strand end 1 c is still largely liquid, so that any voids or cracks in the strand can be filled by liquid melt 12. As a result, the strand has a better internal quality.
  • the Fig. 3b shows another diagram for the extraction speed v, where v depends not on the time t but on the strand length s. This ensures that the strand beginning 1a is cooled more strongly than the strand end 1c, regardless of any interruptions in the casting process.
  • the inner quality of the strand can also be adjusted by adjusting the intensity of the secondary cooling 4 as a function of time or the strand length s (see Fig. 1c ) respectively. In both cases, this means that the strand beginning 1a is cooled more strongly in the secondary cooling 4 is called the strand end 1c. This measure can be done in addition to increasing the Auszieh Anthony v of the dummy bar 6 from the mold 2 or instead of it.
  • the intensity of the secondary cooling is varied as a function of the time t or the strand length s.
  • the time-dependent change in the intensity of the secondary cooling by a change in the flow rate Q through the cooling nozzles 4a of the secondary cooling 4 is in Fig. 4a shown.
  • the decrease of the flow rate Q or the intensity of the secondary cooling 4 can be linear (continuous line) but also sub-linear or superlinear (see dashed lines).
  • the intensity of the secondary cooling can also be varied as a function of the strand length s (see 4b ). In this case, the strand length s during casting is calculated and the intensity of the secondary cooling 4 is determined according to the characteristic of 4b set.
  • Fig. 5 schematically shows the accumulated on the different areas of a teilerstarrten strand 1b amounts of coolant in the time or strand length-dependent adjustment of the intensity of the secondary cooling (see Fig. 4a or 4b ).
  • a possibility according to the invention for improving the internal quality of the strand is shown.
  • the heat insulation 9 is set in the tertiary cooling zone 5 as a function of the strand length L, wherein a heat transfer coefficient U of the heat insulation 9 in the casting direction G increases.
  • the strand beginning 1a is cooled more strongly in the teritary cooling 5 than the strand end 1c.
  • This measure can be done in addition to increasing the Auszieh educa v of the dummy bar 6 from the mold 2.
  • the change in the thermal insulation 9 in the tertiary cooling zone 5 to be carried out in addition to the adjustment of the intensity of the secondary cooling 4.
  • the change in the heat transfer coefficient U of the heat insulation 9 is in Fig. 6 represented by a variable thickness of the insulation.
  • Fig. 7a is a further possibility according to the invention for strand length-dependent change of the thermal insulation 9 in the Tertiärkssel 5 shown by insulation panels 9a.
  • the pivotable flaps of the insulation panels are set differently, the upper flaps are largely closed and the lower flaps are largely open.
  • a heat transfer coefficient U of the heat insulation 9 in the casting direction G increases.
  • the change in the opening angle of the flaps can be preset either statically or dynamically, for example via pivoting drives for pivoting the flaps, during the cooling in the tertiary cooling zone 5.
  • the Fig. 7b shows an alternative to Fig. 7a , wherein the degree of coverage of the insulating flaps 9a of the strand at the strand end 1c is higher than at the strand beginning. This also increases the heat transfer coefficient U of the heat insulation 9 in the casting direction G.
  • Fig. 8a is a non-inventive continuous casting machine with a control or regulating device 10 for controlling or regulating the pullout speed v shown.
  • the control unit 10 taking into account the chemical composition 15 of the molten metal, the primary cooling 2a in the mold 2, the secondary cooling 4 and the strand length s calculates the temperature field and the sump tip in the cast strand 1 and sets the withdrawal speed of the dummy strand via the motor 16 depending on the sump tip.
  • the sump tip is calculated in real time in a thermal calculation model.
  • the Fig. 8b also shows a non-inventive continuous casting machine with a control or regulating device 10 for controlling or regulating the intensity of the secondary cooling 4 as a function of the strand length s.
  • the controller 10 calculates, considering the chemical composition 15 of the molten metal and the primary cooling 2a in the mold and the strand length s, the temperature field and the sump tip in the cast strand 1 and adjusts the intensity of the secondary cooling 4 as a function of the sump tip.
  • the sump tip is calculated in real time in a thermal calculation model.
  • the Fig. 8c Finally shows a continuous casting machine according to the invention with a control or regulating device 10 for controlling or regulating a heat transfer coefficient U of the heat insulation 9 in the Tertiärkühlzone 5.
  • the control or regulating device 10th In consideration of the chemical composition 15 of the molten metal and the primary cooling 2a in the mold, the temperature field and the sump peak in the cast strand 1 are calculated and adjusts the opening angles of the insulating panels 9a depending on the sump tip. The sump tip is calculated in real time in a thermal calculation model.
  • FIG. 9a we poured a strand 1 in the mold 2 and pulled out with variable withdrawal speed v from the mold.
  • the strand 1 is supported and guided in the strand guide 3 and cooled by the secondary cooling.
  • Fig. 9b the casting in the mold was stopped and the strand 1 is located in a radiation area 17, where it can radiate heat to the environment over a certain time.
  • the strand passes through a stirring coil 14 and is electromagnetically stirred by this, see Fig. 9c ,
  • the strand is then introduced into the tertiary cooling zone 5, where it is cooled or controlled by the thermal insulation 9. Since, in particular, the strand end 1 c is particularly sensitive, it is again thermally insulated by a lid, see 9d and 9e ,
  • FIG. 10 schematically a head insulation 18 of a strand 1 is shown.
  • the head insulation has a heat insulation 9 for the strand end 1c of the strand 1, so that the strand end 1c remains liquid longer.
  • an exothermic powder 19 can be applied to the liquid strand end 1c, which additionally heats the strand 1.
  • Fig. 11 is schematically the result of the time- or distance-dependent adjustment of the extraction speed v and / or the time- or path-dependent adjustment of the intensity of the secondary cooling and / or the setting of a heat transfer coefficient U of the heat insulation. 9 shown. All of these measures have the effect of slowing the solidification of the partially solidified strand (see the dashed line indicating the increase in temperature over time). In contrast, the solid line indicates the comparison with the prior art. As stated above, these measures result in the strand having a pronounced V-shape of the strand shell (see Fig. 11 right) in contrast to strands without pronounced V-shape of the strand shell (see Fig. 11 Left).
