Definitions

  • the invention relates to a method for the continuous casting of steel pre-profiles, in particular double-T pre-profiles according to the preamble of claim 1 and an apparatus for carrying out the method.
  • Steel pre-profiles represent primary material for producing rolled steel profile beams in I, H, U and Z-cross-sectional shape and special sheet pile profiles.
  • a method for continuous casting of such pre-profiles is, for example, in EP-B-1 419 021 disclosed. Continuous casting of pre-profiles was introduced industrially in the 70's and has become increasingly important in recent years as part of the general trend towards so-called near-net-shape casting.
  • the pre-profiles are usually cast in a double-T cross-sectional shape, wherein the liquid steel is introduced substantially vertically into a so-called "dog-bone” continuous casting mold whose cavity cross section is composed of two flange parts and a web part. From the mold a Vorprofilstrang with liquid core of a strand guide with secondary cooling devices is supplied.
  • the continuous casting of double-T pre-profiles poses some problems, especially when it comes to pre-profiles with a relatively thin web part, if high-strength special steel grades (CaSi or Alberuhigt and micro-alloyed steels with V, Nb, etc.), or by rapid casting.
  • high-strength special steel grades CaSi or Alberuhigt and micro-alloyed steels with V, Nb, etc.
  • the liquid steel is introduced into the mold via only one gate, usually asymmetrically at the transition between the web part and one of the flange parts.
  • the present invention has for its object to provide a method of the type mentioned above and to provide a device for carrying out the method by which steel pre-profiles, which have two flange and a web portion, can be made with improved quality, even if it is is a relatively thin web part and / or special steel grades.
  • Fig. 1 shows schematically a mold 1 and its horizontal mold cavity cross-section, which is composed of two flange parts 2, 3 and a web part 4.
  • the mold 1 is intended for continuous casting of double-T pre-profiles.
  • the liquid steel is introduced substantially vertically into this continuous casting mold, in which the strand crust forms, and from which a Vorprofilstrang with liquid core of a strand guide with secondary cooling means is supplied.
  • the stirrer 10 shown in Fig. 1 has an annular, the mold 1 in a certain height range surrounding, closed yoke 11 with six pole pieces 12 to 17, wherein each pole piece is surrounded by an electromagnetic coil 19.
  • the pole shoes 12 to 17 are unevenly distributed on the circumference of the yoke 11, such that each pole piece 12, 13 on the flange 2, 3 and two pole pieces 14, 15; 16, 17 are aligned on both sides of the web part 4.
  • the stirrer or rotary stirrer 10 operates on the principle of a 6-pole asynchronous motor in which a traveling field can be generated with the aid of 3-phase current.
  • the correct wiring of the poles is important in order to obtain a linearly moving or rotating field.
  • the mold is again in a certain and preferably adjustable height range of an electromagnetic stirrer 20 surrounded by an annular closed yoke 21, on whose circumference in turn six pole pieces 22 to 27 are distributed unevenly, with the difference that all six pole shoes 22 to 27 are aligned with the web part 4.
  • the mold 1 is assigned in each case an electromagnetic stirrer 30 which has a closed yoke 31 surrounding the mold 1 and designed as a rectangular frame whose longitudinal sides each have three pole shoes 34, 35, 36 and 42 distributed over the mold width 37, 38, 39 are assigned, and the narrow sides are each provided with one on the flange parts 2, 3 frontally aligned center pole piece 32, 33.
  • the stirrer 30 can be operated both as a rotary stirrer and as a linear stirrer, depending on the pole circuit, ie, depending on which pole shoes and with which phase sequence (see phase designation U, V, W, U ', V', W ') Power to be set. It will be explained with reference to FIGS. 3 to 6, four different operating options in which six of the total of eight pole pieces 32 to 39 are under power.
  • the middle pole shoes 32, 33 are switched off in the flange area and the pole shoes 34, 35, 36 are phase-shifted on one longitudinal side of the yoke 31 opposite the pole shoes 37, 38, 39 on the other longitudinal side, whereby a linear, counter-rotating Flow is generated in the web part 4 (2x3-pole linear operation, in opposite directions).
  • middle pole shoes 32, 33 are energized in the flange region, but the middle of the three pole shoes 34, 35, 36; 37, 38, 39, which are assigned to the two longitudinal sides, switched off (pole shoes 35, 38 without power).
  • rotation fields are generated in the flange areas (2x3-pole rotation operation).
  • the direction of rotation of the rotation fields in the two flange 2, 3 is equal, whereby a flow in the web part 4 is formed, which, however, is less efficient than in the linear operation after Fig. 3.
  • FIGS. 7 and 8 show a variant in which the mold 1 has on its circumference two electromagnetic stirrers 40, 40 'or two yokes 41, 41' which are separated from one another in the widthwise direction of the mold 1, each with three pole shoes 42, 43, 44 ; 42 ', 43', 44 'are associated with each yoke 41, 41' with a on the respective flange part 2, 3 frontally aligned middle pole piece 42, 42 'and two on the flange part 2, 3 directed from both sides pole pieces 43, 44; 43 ', 44' is provided.
  • the electromagnetic stirring can be carried out with two independent stirrers or half stirrers, which can be relatively easily brought from outside to the mold 1 / mounted.
  • the free sector creates a designer's freedom.
  • this solution also allows the two stirrers 40, 40 'arranged mutually offset in height, as indicated in Fig. 9, wherein the mutual and / or on the mold height related height arrangement of the stirrer 40, 40' can be preferably adjusted as needed.
  • each yoke is in each case with three pole shoes 52, 53, 54; 52 ', 53', 54 'and 62, 63, 64, respectively; 62 ', 63', 64 'equipped.
  • the three pole pieces 52, 53, 54; 52 ', 53', 54 ' distributed over the entire width of the mold and two of them (pole pieces 52, 54, 52', 54 ') laterally directed to the flange 2, 3, and the middle pole piece 53, 53' projects up to the web part 4.
  • the stirrers 50, 50 'and 60, 60' are operated as linear stirrers, whereby opposing flow (FIGS. 10 and 11) or a corotating flow (FIG. 12) can be produced in the web part 4.
  • FIG. 14 shows an electromagnetic stirrer 70 with an 8-pole structure, constructed in a manner similar to the stirrer 30 according to FIGS. 3 to 6 (with a yoke 71 formed as a rectangular frame whose longitudinal sides each have three pole shoes 74 distributed over the mold width) , 75, 76; 77, 78, 79 and whose narrow sides are each provided with a center-pole shoe 72, 73 aligned in a frontal manner on the flange parts 2, 3).
  • this embodiment does not select between rotational and linear operation by turning off two of the eight poles, but at the same time linear arrays in the ridge portion 4 using a 1x6 pole linear stirrer (pole shoes 74, 75, 76, 77, 78, 79 ) and rotating fields in the flange parts 2, 3 using 2x3-pole rotary stirrers (pole shoes 74, 72, 77 and 76, 73, 79).
  • FIG. 15 shows an electrical diagram of the stirrer 70 with this 8-pole structure or this 8-pole system, in which the linear fields are simultaneously generated by means of a 1 ⁇ 6 pole linear stirrer and the rotation fields using these 2 ⁇ 3 pole rotary stirrers become.
  • This electromagnetic stirrer 70 is fed by the network, for example, with three-phase current 50 Hz, by means of lines 81, 82, wherein the lines 81, 82 each lead to a frequency converter 83, 84.
  • These frequency converters 83, 84 are connected to a converter control 85 and the individual phases are set by this to a predetermined frequency.
  • the control 85 has the task of matching the frequencies of the two converters to one another in order to synchronize the stirring movements generated in the web and in the transition region to the two flange parts. In addition, it should be the appearance of beat phenomena at slightly different Prevent frequencies of the two stirrers. A beating would mean that over time one and the other poles would be under full load at the same time, which would result in a very uneven network load.
  • the individual phases U, V, W of one converter 84 and the phases U 1 , V 1 , W 1 of the other converter 83 are connected to the pole pieces 74, 75, 76; 77, 78, 79 wound coils guided.
  • the phases U, V, W lead to the coils 77 ', 78', 79 'at the pole shoes 77, 78, 79 in the web portion and further to the symmetrically arranged to these coils 76', 75 ', 74' of the pole pieces 76, 75, 74, wherein the connecting lines of the coils 77 ', 79' over the cross to the coils 76 ', 74' (connected in series) are guided.
  • phase W 1 is conducted to the coil 72 'and further to the opposing coil 73' and further to a star circuit 88.
