Definitions

  • the invention relates to a method for continuously casting a metallic product according to the preamble of claim 1, and to a continuous casting installation according to the preamble of claim 10.
  • the liquid metal is continuously cast in a mold, where a first strand shell is formed.
  • the strand emerges downwards from the mold, the strand then being transported along a supporting strand guide.
  • the strand is then moved along a further strand guide with a straightening area, through which the strand is deflected in the horizontal direction.
  • further processing stations for the strand or partial products formed therefrom can be provided along the strand guide, for example in the form of rolling mills through which the strand is passed.
  • the strand hardens or solidifies completely within the supporting strand guide in order to prevent the liquid metal core from breaking out and to enable the strand to be processed further.
  • the cooling capacity in the area of the supporting strand guide and the casting speed are set in such a way that, with an optimal operating sequence, the sump tip of the strand is always in front of or upstream of the last pair of supporting rollers at the end of the supporting strand guide.
  • the strand can bulge , because the hydrostatic pressure of the liquid melt now lacks a counterpressure due to a pair of supporting rollers. This can cause the Strand in a non-area of the strand guide, which does not contribute to the support of the strand and - seen in a conveying direction of the strand - is located downstream of the supporting strand guide, bulges develop due to an increase in the thickness of the strand.
  • the measuring principle according to DE 1 558 345 A with which dents or an increase in thickness on the surface of a moving strand after exiting a supporting strand guide is determined in a mechanical way with a contact measuring roller, is subject to various disadvantages, e.g. wear of the wheels of the mechanical sensors due to the high temperatures of the strand . Furthermore, measurement errors can result if these wheels do not roll cleanly on the broad sides of the strand.
  • JP H02 55652 A It is known to change the casting speed during the production of a strand as a function of the measured strand shell thickness in order to thereby achieve a desired position for the sump tip of the strand.
  • An ultrasonic measuring device is used to measure a strand shell thickness.
  • a precise indication of the point at which such an ultrasonic measuring device is arranged relative to a supporting strand guide is given in FIG JP H02 55652 A not known.
  • EP 2 422 900 A1 an arrangement for measuring physical parameters in continuous casting molds is known.
  • the invention is based on the object of optimizing the continuous casting of a metallic product with regard to quality improvement and at the same time increasing operational reliability, also with regard to preventing undesired bulging following the supporting strand guidance.
  • a method according to the present invention is for making a metallic product.
  • a strand of the metallic product emerges continuously from a mold, in particular vertically downwards, and is then transported along a supporting strand guide in a conveying direction, the strand being deflected in a straightening area in the horizontal direction.
  • a thickness of the strand is measured by a radar measuring device at a measuring position where the strand immediately leaves the supporting strand guide, and then in a step (ii) the measured strand thickness is compared with a first predetermined comparison value .
  • a step (iii) if the measured strand thickness is greater than the first predetermined comparison value, at least one casting parameter is changed in such a way that the sump tip of the strand migrates in the direction of the mold.
  • the invention provides a continuous caster for producing a metallic product.
  • a system comprises a mold and a supporting strand guide which adjoins the mold and along which a strand emerging from the mold, in particular vertically downwards, can be transported in a conveying direction.
  • another strand guide is provided with a straightening area through which the strand can be deflected in the horizontal direction.
  • a radar measuring device with which a thickness of the strand can be measured at a measuring position located directly at the end of the supporting strand guide, and a control device with a computing unit connected to the radar measuring device for signaling purposes, with which the measured strand thickness with a first predetermined comparison value can be compared.
  • the radar measuring device is arranged at a position where the strand emerges from the supporting strand guide.
  • the control device is programmed in such a way that, if the measured strand thickness is greater than the first predetermined comparison value, then a control signal can be generated with which at least one casting parameter is changed in such a way that the sump tip of the strand moves in the direction of the mold.
  • the invention is based on the essential knowledge that the measurement of a thickness of the strand at a measuring position where the strand leaves the supporting strand guide directly is carried out by means of radar technology.
  • a radar measuring device is arranged directly at the end of the supporting strand guide, namely where the strand emerges from the supporting strand guide.
  • radar measurement technology has the advantages that temperature radiation in the near IR range, which emanates from the hot strand, does not affect the radar measurement, and that in the measurement environment water vapor emanating from the Strand cooling by means of water is created without falsifying the measurement from the radar beams penetrating to the strand.
  • a radar measurement is (more) insensitive to contamination compared to an optical measurement using a laser and a mechanical measurement using a touching measuring roller.
  • the radar measuring device With regard to the positioning of the radar measuring device in the continuous caster, it is recommended that a relatively large distance from the hot strand is maintained. This is possible thanks to the non-contact radar measurement. Such a sufficiently large distance between the radar measuring device and the hot line ensures good protection of the radar electronics against the radiant heat emanating from the line.
  • the radar measuring device is arranged relative to the supporting strand guide and the strand emerging therefrom such that the radar beams or waves are directed essentially perpendicularly onto a surface of the strand, namely on its broad side (s). In this way, the radar beams are directed or transmitted perpendicularly by the radar measuring device onto the surface of at least one broad side of the strand.
  • the radar beams are directed, starting from the radar measuring device, from both sides of the strand perpendicular to its broad sides. This ensures a uniform and complete measurement of the thickness of the strand immediately after it has emerged from the supporting strand guide, in connection with the detection of possible "bumps" on the surfaces of the broad sides.
  • Such monitoring of the string from both sides can be achieved in that the radar measuring device has separate transmitting / receiving modules which are arranged on both sides of the broad sides of the string and emit their radar beams or waves essentially perpendicular to the broad sides of the string .
  • the radar measuring device can also have separate parabolic elements which are arranged on both sides of the broad sides of the string and align the radar beams essentially perpendicularly to the broad sides of the string. By deflecting the radar beams in this way by means of the parabolic elements, the actual radar measuring device, with its sensitive transmitter / receiver unit, can be positioned at a sufficient distance from the hot strand and related components of the continuous caster.
  • a further improved protection of the radar measuring device against the high temperatures of the strand can be achieved by thermal insulation layers in which the radar measuring device is encapsulated. This is possible because radar rays penetrate such dielectric materials in the form of thermal insulation layers.
  • An important feature of the method according to the invention, and in the same way of a control device of the continuous casting plant according to the invention set up accordingly in terms of programming, is that, in the event that the strand thickness measured by the radar measuring device should be greater than the first predetermined comparison value, then at least one casting parameter in is changed in such a way that the sump tip of the strand migrates in the direction of the mold.
  • the sump tip - viewed in the direction of conveyance of the strand - is then displaced upstream and thus "migrates" back into the supporting strand guide.
  • Said change of at least one casting parameter is expediently that the casting speed is reduced, but not set lower than a minimum casting speed at which the sump tip of the strand is below LiquidCoreReduction (LCR) segments of the supported strand guide.
  • LCR LiquidCoreReduction
  • the cooling capacity in the area of the supporting strand guide can also be increased.
  • the first predetermined comparison value with which the strand thickness measured by the radar measuring device is compared in step (ii) is a distance between the last two support rollers at the end of the supporting strand guide, ie at its exit area, where the moving strand leaves the supporting strand guide.
  • the deflection is also taken into account, which can occur when the strand is passed through between these opposite support rollers.
  • a reduction in the casting speed has a direct effect on the entire length of the strand, and thus also on the position of the sump tip of the strand, which is hereby shifted upstream, ie against the conveying direction of the strand in the direction of the mold.
  • the present invention it is achieved that by means of a radar measurement the thickness of the strand after it has emerged from the supporting strand guide is measured exactly. In this way, possible bulges of the strand as it emerges from the supporting strand guide can be recognized precisely and reliably, in connection with the initiation of an immediate "countermeasure", preferably in the form of reducing the casting speed.
  • the continuous casting installation 10 comprises a mold 12, which is followed by a supporting strand guide 13 with a total of four segments 13.1-13.4.
  • a mold 12 which is followed by a supporting strand guide 13 with a total of four segments 13.1-13.4.
  • liquid metal is poured into the mold 12 in the region of a melt inlet 6, with a strand S with an initially still liquid core 7 then entering downward from the mold 12 into the supporting strand guide 13.
  • the segments 13.1-13.4 of the supporting strand guide 13 there are each oppositely arranged pairs of supporting rollers 14, 14 ', between which the strand is moved in the conveying direction F.
  • the continuous caster 10 comprises, as evidenced by the side view of FIG Fig. 1 , a further strand guide 19 with a straightening area I, in which the strand S is deflected by bending rollers 22 in the horizontal direction. Following the straightening area I, a pair of scissors 23 is arranged in the strand guide 19, followed by at least one rolling mill 24 and a furnace 26 arranged in front of it.
  • the continuous casting plant 10 comprises a radar measuring device 16 with which a thickness of the strand S is measured at a measuring position 18, namely immediately where the strand leaves the supporting strand guide 13 after passing through the last pair of supporting rollers 14L, 14L ' exit.
  • This measurement position 18 is indicated by an arrow in Fig. 1 illustrated.
  • the radar measuring device 16 has separate transmitting / receiving modules 16.1, 16.2, which are each arranged on both sides of the broad sides of the strand S, and with which radar beams are then each directed perpendicularly onto the surface of a broad side of the strand.
  • transmitting / receiving modules 16.1, 16.2 which are each arranged on both sides of the broad sides of the strand S, and with which radar beams are then each directed perpendicularly onto the surface of a broad side of the strand.
  • a distance between these transmit / receive modules 16.1, 16.2 from the supporting strand guide 13 and the hot strand S guided therein is sufficiently large so that these modules are not damaged by the thermal radiation emanating from the strand S.
  • the continuous casting plant 10 comprises a control device 20 with a computing unit 21, which is connected for signaling purposes to the radar measuring device 16, the bending rollers 22 in the region of the strand guide 19 and the at least one rolling mill 24, in Fig. 1 each symbolized by dotted lines.
  • a control device 20 with a computing unit 21, which is connected for signaling purposes to the radar measuring device 16, the bending rollers 22 in the region of the strand guide 19 and the at least one rolling mill 24, in Fig. 1 each symbolized by dotted lines.
  • the arithmetic unit 21 also provides information regarding both a distance between the bending rollers 22 and the distance from (not shown) Work rolls of the rolling mill 24 receives.
  • a minimum casting speed V min is determined on the basis of the current process values (chemical analysis of the material, strand thickness, set cooling capacity for the segments 13.1-13.4 of the supporting strand guide 13), at which the sump tip SP below the two LCR segments 13.1, 13.2 (see illustration in Fig. 4 ).
  • the radar measuring device 16 continuously measures a thickness of the strand S, as explained above at the measuring position 18, ie immediately where the strand S emerges from the end 15 of the supporting strand guide 13. This corresponds to a step (i) of a method according to the present invention, the measured strand thickness being transmitted to the computing unit 21 of the control device 20.
  • the measured strand thickness is compared with a first compared with a predetermined comparison value, which corresponds to a distance between the two last support rollers 14L, 14L '.
  • the control device 20 immediately generates a control signal with which, for example, the casting speed is set to a reduced value V red .
  • a query is carried out in the arithmetic unit 21 for the further course of the continuous casting process as to whether the strand thickness measured by the radar measuring device 16 in step (i) is less than a predetermined second comparison value , which corresponds to a distance from oppositely arranged bending rollers 22. If a "No" is determined in this query, meaning that the strand thickening of the strand S can no longer be transported through the bending rollers 22, the control device 20 emits a control signal for an immediate interruption of casting in order to avoid further damage to the strand guide 19 the continuous caster 12 to avoid.
  • a further query takes place in the computing unit 21 as to whether the strand thickness measured by the radar measuring device 16 in step (i) is less than a predetermined third comparison value, which corresponds to a distance between oppositely arranged work rolls in the rolling mill 24. If a "No" is determined in this query, this is synonymous with the fact that the existing strand thickening in the rolling mill 24 cannot be brought to a desired final dimension. Therefore, the control device 20 then generates a control signal for the scissors 23, by means of which the thickened section of the strand S is separated from the strand guide 19 and shredded accordingly.
