Definitions

  • the invention relates to a mold for the continuous casting of metals, preferably steel, according to the preamble of claim 1 or claim 2.
  • DE-A-3 907 351 describes a mold with a pouring funnel for a thin slab.
  • the two broad sides are provided with bulges on the pouring side of the mold, which are continuously formed back along a partial height of the mold.
  • the cross section of the mold cavity is rectangular and aligned with the desired thin slab cross section.
  • the sole purpose of the two opposite bulges is to create the space required for a dip tube. No bulges and no deformation of the strand shell through the mold walls are provided on the two narrow sides.
  • a mold with a mold cavity open on both sides for continuous casting of a thin strand is known.
  • the circumferential line of the mold cavity cross section on the pouring side can be divided into four circumferential sections.
  • Cross-sectional enlargements in the form of bulges compared to the same cross-section on the strand exit side are provided on two sides of the circumference, which simultaneously form the broad sides of the thin strand cross section.
  • the size of the bulge which corresponds to the arch height in this example, decreases continuously in the direction of the strand and is zero at the mold exit.
  • the narrow side walls diverging in the direction of the strand run on the two other circumferential sections, the narrow sides of this thin slab mold.
  • These narrow sides, which diverge in the direction of the strand, are necessary to solve the task set there, in order to prevent bruises and wrinkles on the broad sides.
  • An improvement or equalization of the cooling over the entire mold circumference and associated improvement of the strand quality with regard to surface and structure cannot be achieved with this mold because the narrow and broad sides have different conicity and therefore cool to different degrees. If the casting speed varies greatly, this different cooling is intensified.
  • An increase in the casting speed is limited by the indefinite cooling conditions on the narrow sides.
  • the strong cooling of the broad sides and the weak cooling of the narrow sides further increase the risk of breakthroughs in the case of widely varying, but especially at high, casting speeds.
  • the invention has for its object to overcome the disadvantages mentioned.
  • deformation of the strand cross section within the mold is intended to achieve cooling of the strand crust that can be measured over the entire circumference, in order to improve the strand quality on the one hand and to increase the casting speed on the other hand.
  • differences in casting speed during a running casting should also be made possible without the disadvantages mentioned, such as strand break and breakthrough.
  • the mold according to the invention it is possible, in the case of billets and small pre-block cross sections, to force cooling that is uniform in all circumferential sections and that can be measured in terms of its intensity within predetermined limits. This can influence the crystallization of the strand crust and improve the strand quality. Skewed edges, surface and structural defects are avoidable.
  • the cross section can further improve the uniformity of cooling along the strand circumference, even at different casting speeds, in the mold according to the invention. The risk of strand breaks or breakthroughs can be significantly reduced at high casting speeds.
  • the bulges of the mold cavity in each section of the circumference on the pouring side each represent curved lines in the mold according to the invention, which have a higher dimensional stability of the mold tube, in particular in the highly heat-exposed bath level area, compared to classic tubular molds. With tube and other molds, this higher dimensional stability improves the dimensional stability of the mold cavity during the service life of the mold on the one hand and the strand quality on the other.
  • the bulge is usually reduced from the pouring side along the mold cavity over a part length or over the entire length of the mold.
  • a curved line can remain in each circumferential section.
  • the mold can also be round or a pre-profile, e.g. in the form of a double-T beam.
  • the difference between the arc length at the bath level and at the mold exit or the chord length at the mold exit is determined and compared with the shrinkage of the strand crust transverse to the direction of the strand.
  • the difference mentioned can be selected by the size of the bulge or the bend height so that it is essentially in agreement with the shrinkage mentioned.
  • the light dimension between opposite circumferential sections of the mold cavity on the pouring side measured in the region of the largest bulge, can be selected to be about 5-15%, preferably at least 5% or 8%, larger than the light dimension between opposite circumferential sections on the strand exit side.
  • the dimension of the arc height can decrease degressively or possibly progressively in the casting direction and can approach zero. According to a further embodiment, the dimension of the arc height can advantageously decrease steadily in the cross-sections following the strand running direction. According to a further exemplary embodiment, the change in the bow height in the strand running direction can also be defined as a degree of taper.
  • the shape and size of the bulge are the same in all sections. The conicity of the bulge changes in size along the circumferential section. According to one embodiment, a taper between 0 and 1% / m and at the center of the peripheral section between 10 and 35% / m can be provided at the two ends of each peripheral section.
  • Another possible variation is the choice of the length or partial length of the mold cavity with bulges.
  • the arc height of the bulge is reduced over the entire length of the mold cavity.
  • An advantageous embodiment provides for a partial length of at least 50% of the mold length. In today's molds of 800 mm length, the partial length is at least 400 mm.
  • the taper in the corners or in the corner areas is greater by a factor of 2 than on the side walls.
  • this fact can lead to jams and strand breaks.
  • the strand cross-sectional shape is deformed according to the invention as it passes through the partial length of the mold cavity and the cooling capacity is controlled in the process.
  • the design of the taper can be freely selected, regardless of the size and degree of taper of the bulge.
  • the corners of the mold cavity are rounded in polygonal strand cross sections. It has proven to be particularly advantageous if the corners of the mold cavity have fillets with a radius of 3 to 8% of the side length of the cross section.
  • the circumferential sections with bulges can be composed of circular lines, curves or of th straight lines.
  • FIG. 1 and 2 show a mold 3 for the continuous casting of polygonal strand cross sections, in the present example of square strand cross sections.
  • An arrow 4 points to a pouring side and an arrow 5 to a strand exit side of the mold 3.
  • the cross sections of a mold cavity 6 have different geometrical shapes on the pouring and strand exit side. 2, the cross-section of the mold cavity 6 on the pouring side 4 between the corners 8-8 "'is provided with cross-sectional enlargements in the form of bulges 9 compared to the strand exit side.
  • An arc height 10 which represents the extent of the bulge , decreases steadily in the strand running direction 11 over a partial length 12 of the mold cavity 6.
  • the mold cavity cross sections in the planes 14 and 15 delimit a Kokiiienteii 13 with a square cross section with fillets 16, as is known in the prior art.
  • a circumferential line 17 shows the mold cavity cross section in the plane 14 and a circumferential line 18 shows the mold cavity cross section in the plane 15.
  • the cross section of the mold cavity 6 is straight on all sides between the corners 8 on the mold exit side.
  • An arrow 2 denotes a peripheral section of the peripheral line of the mold cavity 6.
  • 4 peripheral sections with similar cross-sectional enlargements 7 are provided.
  • a hexagonal, rectangular etc. cross section could also serve as the basic shape.
  • a light dimension 20 between opposite sides of the mold cavity 6 on the pouring side 4 in the area of the largest bulge is 5 to 15% larger than a light dimension 21 between the opposite sides on the strand exit side 5.
  • the light dimension 20 can also be at least 5% or at least 8% larger than the light dimension 22 in the plane 14 at the end of the partial length 12.
  • the arch height 10 of the bulge 9 decreases continuously in the direction of the strand 11 with the following cross sections.
  • the taper of the maximum arc height 10 along a line 24 can be according to the formula are calculated, where Bo denotes the mold width at the top or light dimension 20 in mm, Bu the mold width at the bottom or light dimension 22 in mm, L the decisive length in m and T the conicity (or taper) in% / m. Conicities of 10 - 35% / m can be selected using this formula.
  • the part length 12 in this example is 400 mm or about 50% of the mold length, which measures about 800 mm.
  • FIG. 3 shows height curves 30-33 a corner of a bulged mold cavity 35.
  • the height curve 30 represents the top edge of the mold cavity 35 of the mold 34.
  • the wall thickness of a mold tube is indicated by 36.
  • 33 shows the height curve at the mold exit. Between the curves 30 and 33, the taper can be read out at two intermediate heights. Curves 31 and 32 show the decreasing arc heights of the bulges, which cause the strand crust to deform during casting.
  • the taper of the mold cavity 35 along a diagonal cut along the line 39 is 0-1% / m, preferably 0.1-0.5% / m. A deformation of the strand crust along line 39 is generally not provided.
  • FIG. 4 shows similar height curves 40-43 as in FIG. 3.
  • the main difference lies in the design of the fillet 48 along the diagonal line 49.
  • the fillet 48 has a negative cone in the direction of the strand. In the corner area in the strand running direction, an expansion of the mold cavity is thus provided.
  • the selected arc height of the bulge that has to be deformed back it may be of interest to provide a negative cone at the corners 48 along the diagonal line 49 in order to prevent any jamming of the strand in the mold.
  • the cooling in the edge area of the strand can also be controlled.
  • a negative taper along the diagonal line 49 may also be desirable to accommodate tendon extensions when reshaping bulges that are not compensated for by the shrinkage the.
  • Fig. 5 the bulges are delimited by compound straight lines. Elevation curves 50 - 53 represent a steady decrease in the bulges. In order to ensure that there are no abutting edges in the middle of the bulged sides, a rounding 54 is appropriate.
  • the straight lines run tangentially to a fillet 58. In this example, no taper is provided along the groove 58 in the direction of the strand. In a section along the diagonal 59, the fillet 58 runs essentially parallel to the longitudinal central axis of the mold.
  • the taper of the fillets 38, 48, 58 in FIGS. 3-5 calculations and / or casting tests are necessary.
  • the shrinkage of the strand crust transversely to the direction of the strand running can be calculated at a specific casting speed and compared with the tendon extension.
  • the taper in the corner area can be determined from the difference between the two values. It should be noted that at high casting speeds, i.e. with short dwell time of the strand crust in the mold, the value for the shrinkage is smaller than at low casting speeds.
  • FIGS. 6 and 7 show molds whose mold cavities 60 and 70 are delimited by curved and circular surfaces.
  • Circumferential lines 61, 71 of the mold cavity cross section are each divided into three peripheral sections 62, 72.

  • Each peripheral section 62, 72 on the pouring side has a cross-sectional enlargement in the form of a bulge 63, 73 in relation to the strand exit side.
  • the cross-sectional enlargements are represented by bulges delimited by an arc.
  • the dimension of the bulge 63, 73 is represented by arrows 65, 65 ', 65 "and 75, 75' and by their length. This dimension decreases on the partial length of the mold cavity in such a way that the strand cross-sectional shape deforms as it passes through the partial length.
  • the shape and the size of the bulge 63, 73 are the same in all the circumferential sections 62, 72.
  • the conicity of the bulges 63, 73 measured in the direction of the strand run are different in size along the circumferential sections 62, 72.
  • each circumferential section 62, 72 is the taper zero to 1% / m and in the middle 67, 77 of the circumferential sections a taper between 10 - 35% / m is generally provided.
