Definitions
- the invention relates essentially to a mold for continuous casting polygonal strands, according to the preamble of claim 1.
- Continuous casting is continuous a molten metal through a pouring opening into a mold cavity poured into a mold, by cooling the melt on the walls of the Form cavity formed a strand shell of continuously increasing thickness and continuously pulled a strand from an outlet opening of the mold cavity, which usually has a still liquid core and is complete Solidification must be subjected to post-cooling.
- the continuous caster is the shape of the mold cavity walls. The Interaction of the strand shell that forms with the mold cavity walls determines the heat transfer between the strand shell and the mold cavity walls and consequently the growth of the strand shell.
- the interaction the strand shell with the mold cavity walls also has an influence on the magnitude of the frictional forces that arise when pulling a strand from the Mold cavity must be overcome and because of the limited mechanical Stability of the strand shell, depending on the chemical composition the melt, do not exceed a certain critical value may, if undesirable, reduce the productivity of the continuous caster Strand breaks or strand breaks should be avoided.
- the Mold cavity walls In order to achieve the highest possible casting speed during continuous casting and at the same time to avoid strand breaks or strand breaks, the Mold cavity walls should be shaped so that they are as uniform as possible Strand shell growth is realized.
- Various constructive measures are known to optimize strand shell growth.
- the mold cavity To education due to gaps between the mold cavity walls and the strand shell the increasing thermal contraction in the direction of the outlet opening avoid, the mold cavity is designed in the form of a casting cone that the thermal contraction of the strand should take into account.
- the optimal shaping of the pouring cone is a general problem because of the Variety of parameters known to increase strand shell growth have an influence. For example, the chemical composition play of the molten metal, the shape and size of the cross section of the mold cavity and the casting speed matter.
- US Pat. No. 4,207,941 describes a mold used for continuous casting is provided by essentially square strands and all features of the preamble of claim 1.
- the mold cavity of this mold is formed by a tube that is conical over its entire length, the three adjacent, in terms of size and location longitudinal sections which can be distinguished by the conicity include: an entrance section, located in the foundry above the pouring level; a middle section, at the upper end of which the pouring mirror in the pouring operation is positioned and in which the initial solidification of the strand takes place; and an end section which supports the strand shell at the outlet opening.
- the entrance section has four curved corner areas, each through planar intermediate areas are connected, two of each of the intermediate areas abut one another at a right angle at one of the corner areas.
- the taper is constant in the area of the entrance section, i.e. the light
- the width of the mold cavity increases linearly with the distance from the pouring opening from.
- the taper of the mold cavity depends both on Distance from the pouring opening as well as from the position in one plane across to the direction of the strand.
- the middle section is made up of curved ones Corner areas, each by one of three levels, in one obtuse angles between the mutually forming facets are connected. The taper is greatest in the corner areas of the central section and here regardless of the position in the strand running direction.
- Two of the three facets each forming one of the intermediate areas are adjacent one of the corner areas and have the shape of triangles, which are in Line direction linear as a function of the distance from the pouring opening widen.
- Two of the triangular areas meet at each of the corner areas Facets of neighboring intermediate areas at an angle of approx. 92 ° to each other.
- the intermediate areas of the middle section is the Taper constant on each of the facets, with taper on the triangular, to one of the facets adjacent to the almost right-angled corner areas is greatest. At the boundaries between the facets there are cracks Conicity.
- the mold cavity In the area of the end section, the mold cavity has the same twelve-sided shape Shape like at the border between the end section and the middle section.
- the taper in the entire end section is constant and smaller than that Taper in the area of the various facets that cover the central section of the Form the mold tube.
- a disadvantage of this mold is that cannot be prevented in the twelve-sided areas of the mold cavity may cause the strand shell to detach itself locally from the mold cavity walls and assumes a shape which, during the extrusion of the shape of the Mold cavity walls do not follow perfectly and their geometry can only be controlled imprecisely is.
- the result is the formation of gaps between the Strand shell and the mold cavity walls, combined with a local reduction the heat dissipation.
- local increases in the contact pressure occur between the strand shell and the mold cavity walls, so that the frictional forces are not reduced to a minimum.
- the mold according to the invention has a mold cavity with at least three corner areas and three intermediate areas between the corner areas and with a pouring cone.
- the taper varies at least in the partial length range of the casting cone along a circumferential line in a cross-sectional area in one or more of the intermediate areas such that the taper towards the center of the respective intermediate area decreases.
- This design of the pouring cone takes into account the tendency of a strand shell to form in the mold cavity, due to their mechanical stability under the influence of the Strand shell of the impressed temperature profile and the ferrostatic pressure during cooling when pulling out the strand in the corner areas shrink than in the middle of the intermediate areas.
- the circumferential line between the corner areas is a smooth curve, i.e. a curve, whose tangent does not change its direction discontinuously along the curve, forms.
- a smooth curve i.e. a curve, whose tangent does not change its direction discontinuously along the curve, forms.
- the mold according to the invention is the casting cone formed in a portion of the mold cavity.
- the taper with the distance from the pouring side The end of the pouring cone varies.
- the mold according to the invention is the taper in the middle of the intermediate areas in the area of the partial length regardless of the distance from the end on the pouring side the pouring cone, i.e. the clear width of the mold cavity changes in relation to the middle of the intermediate areas, linear with the distance from the pouring side End of the pouring cone.
- the Taper in and / or at the corner areas is generally larger than in the middle of the intermediate areas, but takes at least piecewise non-linear and / or linear and / or parabolic with the distance from the pouring end of the pouring cone.
- the taper can be in and / or at the corner areas may be the same or even smaller than that Taper in the middle of the intermediate areas.
- mold can be achieved with a taper that is in the middle of the intermediate areas, averaged over the entire length of the casting cone, 0 - 0.7% / m, is preferably 0.2-0.6% / m, and averaged in and / or at the corner areas over the entire length of the casting cone, a value in the range 0.7 - 1.5 % / m, preferably 0.8 - 1.3% m.
- the mold according to the invention is the circumferential line in a cross-sectional plane of the mold cavity in the area the partial length is at least piece-like arched and / or rectilinear.
- the intermediate area takes place between one of the adjacent corner areas and the center of the intermediate area is reversed in curvature.
- a Circumference with a continuous course of curvature therefore points between the middle of the intermediate area and the adjacent corner areas a turning point.
- each section of the circumferential line in a cross-sectional area of the mold cavity between the corner regions a universal curve is representable, which - normalized with regard to its extreme values - is independent of the distance from the pour-side end of the pouring cone.
- This specification of a universal curve has several advantages. Manufacturing technology there is the advantage that the pouring cone has only a few Parameter can be characterized. For example, it is sufficient to specify the universal function, which has a location coordinate as a variable, and the Course of the taper at the corner areas and in the middle of the intermediate area as a function of the distance from the pouring end of the pouring cone.
- a particularly simple parameterization of the circumferential line results in a Representation as a fourth-order parabola. Furthermore, an analysis of the Contact forces between the strand shell and the mold cavity walls that this form of the circumferential line results in particularly low contact forces.
- a prerequisite for the lowest possible contact pressure is a slight curvature the circumference. This requirement is met, for example by a circumference with an inflection point between the center of one of the Intermediate areas and one of the adjacent corner areas.
- a particularly even strand shell growth can be achieved if two the portions of the circumferential line that abut one of the corner regions Form angles that are in the area of the partial length regardless of the distance from the pouring side Is the end of the pouring cone.
- An embodiment of the invention Chill mold has a mold cavity whose cross-sectional area on pouring end of the pouring cone corner areas with a corner angle of each 90 ° and its intermediate areas along the entire length of the The pouring cone meet at a right angle.
- This design concept is based on the fact that a strand which is a has rectangular cross-sectional area, while cooling in the mold while the strand pullout tends to shrink in such a way that in the immediate vicinity the corners of the sides of the strand meet at a right angle.
- This conservation of angles in the course of the shrinking process is a result of the interaction of the mechanical properties of the Strand shell with the temperature profile and formed in the strand shell the ferrostatic pressure acting on the strand shell.
- the mold cavity of the mold according to the invention can be in the corner areas Fillets with a radius of 2 - 8% of the inside diameter of the outlet opening exhibit.
- FIGS. 1 and 2 represent a longitudinal and a cross section through the same Embodiment of a mold according to the invention.

- the casting cone 10 ' is in a longitudinal section 15' of the mold cavity 10 between a cross-sectional area 24 in the vicinity of the inlet opening 11 and the Exit opening 12 formed.
- the pouring cone 10 'in FIGS. 1 and 2 is in the direction of the outlet opening 12 increasing narrowing of the mold cavity 10 is drawn in excessively large.
- 2 shows a plan view of a longitudinal section of the mold tube 5, which is delimited on one side by the cross-sectional area 24 and on the other hand by a cross-sectional area 25 between the cross-sectional area 24 and the outlet opening 12.
- FIG. 1 again illustrates 2 shows a longitudinal section along the line I - I in FIG. 2.
- the mold cavity 10 has four corner areas 13 in the form of fillets.
- the corner areas 13 are defined by intermediate areas 14 ', 14' ', 14' '', 14 '' '' in the form of curved surfaces connected.
- Fig. 1 the course of the corner areas 13 is in each case indicated by a line 13 which is the cutting line of the mold cavity delimiting surface and the diagonal surfaces of the mold cavity 10 surrender.
- the sections are the circumferential line of the mold cavity 10, which each connect two corner regions 13 in the cross-sectional area 24, straight lines.
- the corresponding sections 26 ', 26' ', 26' '', 26 '' '' of the The circumferential line 26 of the mold cavity 10 in the cross-sectional area 25 is in pieces arcuate lines. Two of the sections 26 ', 26' ', 26' '', 26 ''''' butt each at one of the corner areas 13 at a right angle, determined as Intersection angle of the tangents of the respective sections on the relevant one Corner area 13, together.
- the inside width of the mold cavity increases 10 in the middle 32 in the direction of the outlet opening 12 linear with the distance Z from the one-sided end of the casting cone 10 '.
- In and / or at the corner areas 13 takes the inside width of the mold cavity 10 at the pouring end 24 of the casting cone 10 'initially much stronger with the distance from end 24 of the pouring cone 10 ′ on the pouring side than in the middle 32 of the intermediate regions 14 ', 14' ', 14' '', 14 '' ''.
- the relative change in the inside width of the mold cavity 10 is determined in and / or at one of the corner areas 13, as a function of the distance Z and reaches values of the same order of magnitude as the relative change the clear width, determined in the middle 32 of the intermediate areas 14 ', 14' ', 14 '' ', 14' '' '.
- the pouring cone 10 ' can be characterized quantitatively by specifying the conicity K, which is defined in this context as the quotient of the magnitude of the gradient of the inside width of the mold cavity 10 and the inside width, in each case determined for a specific location in the corner areas 13 or the intermediate areas 14 ', 14'',14''', 14 '''' in units of% / m.
- the indices "M" or "E” refer to the center 32 or the corner regions 13, the sizes W M or W E according to FIG.
- the other sections 26 ′′, 26 ′′ ′′ and 26 ′′ ′′ can be treated analogously.

- Z is given in units of the length L K of the section 15 ', ie the longitudinal extent of the casting cone 10' in the casting direction. 4, the taper K M (Z) is constant.
- the taper K E (Z) at the pour-side end 24 of the casting cone 10 ' is approximately a factor 8 greater than K M (Z) and decreases at least in parts non-linearly and / or parabolically and / or linearly as the distance Z increases.
- the course of K M (Z) is compatible with K E (Z) ⁇ K M (Z) for Z> 0.6 L K.

- ⁇ Y max is in the range ⁇ Y max ⁇ 1 mm.
- the parameters illustrated in FIGS. 4-6 can be modified to a certain extent without significantly influencing the properties of the mold according to the invention.
- waiving this requirement leads to tolerable changes that can be compensated for by a corresponding change in the courses of K E (Z) and K M (Z).
- Comparisons of different geometries of the casting cone 10 ' show that the mold according to the invention can be expected to achieve uniform strand shell growth if the taper K M in the middle between 14', 14 '', 14 '''and14''', averaged over the entire Length of the casting cone 10 ', 0-0.7% / m, preferably 0.2-0.6% / m, and the conicity K E in and / or at the corner regions 13, averaged over the entire length of the casting cone 10', is a value in the range 0.7 - 1.5% / m, preferably 0.8 - 1.3% / m.
- the circumference of a cross-sectional area of the mold cavity 10 in the area of the casting cone 10 'between the corner areas 13 should be a smooth curve. Studies have shown that selective abrupt changes in the direction of the tangent when passing through a Point between the corner areas 13, the formation of columns between the Promote the mold cavity wall and the strand shell around this point and disrupt the growth of the strand shell locally, even if the direction the tangent abruptly changes by only 2 ° when passing through this point changes.
- the dashed line in FIG. 6 describes a section of a circumferential line of the mold cavity of a mold, the pouring cone of which follows the "natural shrinkage" of the strand shell.
- intermediate areas 14 ', 14'',14''', 14 '''' which are essentially flat in the middle 32 over a wide area (in FIG. 6 for - 0.3 ⁇ X / L ⁇ 0.3).
- the intermediate regions are curved in an S-shape, with a circumferential line in a cross-sectional area of the mold cavity 10 in the region of the S-shaped sections of the intermediate regions 14 ', 14'',14''', 14 '''' each has an inflection point.
- the position of the turning points and the width of the S-shaped curved sections of the intermediate regions 14 ', 14'',14''', 14 '''' depends strongly on the distance Z 2 from the pour-side end 24 of the casting cone 10 ', in particular for small Z 2 .
- the concept of natural shrinkage leads to shapes of the intermediate regions, which in one cross-sectional area of the mold cavity 10 at the corner regions 13 in one the region widening as the distance Z 2 widens, and consequently also have a greater relative change in the taper K along the circumferential line of a cross-sectional area, based on the width of the S-shaped sections.
- results discussed above are for straight and curved mold cavities applicable.
- the results mentioned are not only applicable to molds for Continuous casting of essentially square strands. they are transferable to molds for the casting of essentially polygonal ones Strands with at least three corner areas and three intermediate areas. At such molds, it is advantageous if two of those adjacent to one of the corner areas Intermediate areas form a corner angle that is independent of the distance from the pour end of the pouring cone.
- the shape of the Intermediate areas are those discussed in connection with FIGS. 4, 5 and 6 Statements applicable.
- the aforementioned embodiment of the mold according to the invention relates on a pouring cone, the circumferential lines between the corner areas are formed from straight lines at the pouring end of the casting cone 10 ' and that with increasing distance from the pour-side end 24 of the pouring cone 10 'have an increasingly convex curvature.
