Definitions
- the invention relates to a continuous casting mold for the continuous casting of a steel strand, preferably for casting thin slabs with a thickness of less than 100 mm, with opposing broad side walls and with clampable between the broad side walls and arranged along the broad side walls transversely to the casting direction, opposing narrow side walls becoming narrower in the casting direction , wherein the broad side walls have a funnel-shaped pouring area which extends in the casting direction to the end of the mold and the distance of the broad side walls from one another in the direction of the narrow side walls and in the casting direction is continuously reduced at least over partial areas of their extent and the broad side walls are designed to be convergent.
- a continuous casting mold of the generic type is already known from DE-C 35 01 422. Their broad side walls are towards the narrow side walls and in
- Casting direction converged.
- the wide side walls have flat contact surfaces in the adjustment region of the narrow side walls, which interact with the side walls of the narrow side walls. If a format adjustment is to be carried out in the mold, this is usually a displacement of the narrow side walls in the sense of a change in the width of the steel strand to be cast.
- the strand thickness and thus the distance between the broad side walls should be kept constant here.
- keeping the distance between the broad side walls constant is only possible with a format adjustment of the known continuous casting mold if the narrow side walls are displaced both in the horizontal and in the vertical direction.
- the formation of the broad side walls in the adjustment area of the narrow side walls with a flat surface requires their skewed position in relation to the longitudinal axis of the mold. Due to these geometric restrictions, it is no longer possible to design the outlet cross-section such that the strand thickness is constant over the entire strand width for each strand format to be cast.
- a continuous casting mold is also known from EP 0 658 387 A1, the broad side walls of which are designed to converge in some areas in the direction of the narrow side walls and in the casting direction.
- the broad side walls have flat surface contours in the adjustment region of the narrow side walls, which interact with the side surfaces of the narrow side walls and whose distance from one another decreases linearly in the direction of the narrow side walls and is constant in the casting direction.
- this embodiment automatically also causes its thickness adjustment in a ratio which is predetermined by the geometry.
- this undesirably limits the spectrum of the strand formats to be cast using such a continuous casting mold.
- the object of the invention is therefore to avoid the disadvantages described above and to propose a continuous casting mold with a funnel-shaped pouring area, which enables a format adjustment in which the strand width of the strand to be cast is set without having any effect on the strand thickness and the strand thickness of the strand to be cast is via the entire strand width can be kept constant.
- Broad side walls is constant and at least one of the broad side walls is slidably and tiltably arranged with respect to the opposite broad side wall on a mold frame and is connected to an adjusting device.
- the broad side walls are plane-parallel in the adjustment area of the narrow side walls, the converging course of the broad side walls in the adjustment area results in fewer curvatures in the funnel-shaped pouring area and thus problem-free strand shell formation.
- the proposed mold geometry which is aimed in particular at a low-tension and thus crack-free strand shell formation, causes a wedge-shaped gap between the broad side wall and the narrow side wall when the format is adjusted, but this is a maximum of only a few millimeters and due to the tilting movement of the Broad side wall can be easily compensated. If one of the two opposite broad side walls is firmly anchored on the mold structure and thus forms a fixed side, the narrow side wall arranged between these two walls is also tilted by the displaceable and tiltable broad side wall, and a gap-free mold cavity for melt absorption is thus formed for each adjustable strand format.
- Tilting of the narrow side walls is avoided when they are clamped between the wide side walls and the necessary tilt angle for the wide side wall is halved if each of the wide side walls is slidably and tiltably arranged on a mold frame and is connected to an adjusting device.
- An expedient embodiment of the continuous casting mold is that the opposite broad side walls are connected to an adjusting device which covers both broad side walls.
- a special constructive solution is that the tiltable broad side wall is articulated to the adjusting device.
- Optimal conditions for the continuous shell formation in the continuous casting mold are obtained if, based on a horizontal plane receiving the casting level under constant casting conditions, the inclination oi of the broad side wall in the funnel-shaped pouring area is 1 ° to 5 ° and the inclination oc 2 of the broad side wall in the adjustment range of the narrow side wall between 0 , 1 ° and 0.3 °.
- a simple structure of the continuous casting mold according to the invention is achieved in that each broad side wall is detachably fastened to a supporting wall, and the adjusting device is connected to at least one of the supporting walls which can be displaced and tilted together with the wide side wall.
- the coolant channels for the mold cooling are incorporated at the contact level between the broad side wall and the support wall in the broad side wall or the support wall in the form of coolant slots.
- a support wall is arranged between the broad side wall and the support wall, the broad side wall being detachably fastened to the support wall and the support wall to the support wall.
- the coolant channels for the mold cooling are incorporated at the contact level between the broad side wall and the support wall in the broad side wall or in the support wall in the form of coolant slots.
- the geometry of the coolant channels in the funnel-shaped pouring area of the broad side walls and the geometry of the coolant channels in the adjustment area of the narrow side walls are different. Geometry of the coolant channels is to be understood on the one hand as the distance between the coolant channels from one another, and on the other hand as the clear width (cross-sectional area) of the coolant channels and thus the coolant flow rate or the combination of both influencing variables. Both measures vary the specific heat flow density of the broad side walls.
- this is achieved in that groups of adjacent coolant channels are connected by lines to individually controllable coolant stations, with at least one coolant supply station being assigned to the funnel-shaped pouring area and the adjustment areas of the narrow side walls of each broad side wall.
- at least the inner walls of the broad side walls forming the mold cavity are formed by different materials in the casting direction, the material used in the area of the casting level having a lower thermal conductivity than that for the subsequent one in the casting direction Section of the broad side walls used material.
- the broad side walls in the area of the casting mirror where particularly high temperatures occur and solidification is not immediately desired, consist of non-ferrous metals, refractory materials or various combinations thereof.
- Narrow side walls with electromechanical or hydraulic drives are particularly cost-effective and reliable.

- Two broad side walls 1, 2 and two narrow side walls 3, 4 of a continuous casting mold form a mold cavity 5, into which molten steel is introduced via a pouring tube (not shown) and from which a partially solid steel strand is conveyed out of the continuous casting mold in the direction of casting.
- the broad side walls 1, 2 and the narrow side walls 3, 4 are usually made of copper or a copper alloy or another very good heat-conducting material.
- the broad side walls 1, 2 are supported on support walls 7, 8 and screwed to them.
- the narrow side walls 3, 4 are supported and screwed to support walls (not shown).
- the narrow side walls 3, 4 positioned between the wide side walls 1, 2 can be displaced transversely to the casting direction 6, a possible position being shown with dashed lines.
- the narrow side walls 3, 4 are with their vertical end regions articulated with narrow-side adjusting devices 9, 10 and mounted on the permanently anchored mold support structure 1 1. These narrow-side adjusting devices are not shown for the narrow side wall 4.
- the opposing support walls 7, 8 of the broad side walls 1, 2 are penetrated by tie rods 14, 15 of the adjusting devices 12, 13 and can be fixed to one another, with
- each adjusting device 12, 13 is assigned a separately controllable pressure medium cylinder 16.
- the narrow side walls 3, 4 are narrowed in a wedge shape in the casting direction 6.
- the adjusting devices 9, 10, 12, 13 can be equipped with any electromechanical or hydraulic drives.
- the broad side wall 2 is designed as a fixed side, i.e. together with the support wall 8, it assumes a clearly defined position with respect to the mold structure 11.
- the loose side formed by the broad side wall 1 and the associated support wall 7 is supported in the mold supporting structure 11 on slides 17 on guides 17 transversely to the casting direction 6 and with the adjusting devices 12, 13 against the narrow sides walls 3, 4 and together with these against the firmly positioned broad side wall 2 can be pressed on, this being done by shifting in the direction of the guides 17 and tilting around the lower or upper inner edge 18, 18a of the broad side wall 1.
- both broad side walls 1, 2 are designed as loss sides and are supported in the mold supporting structure 1 1 on guides 17 which can be displaced transversely to the casting direction 6 and with which
- Adjusting devices 12, 13 can be pressed against the narrow side walls 3, 4 on both sides, this being done by shifting in the direction of the guides 17 and tilting around the lower or upper inner edge 18, 18a, 19, 19a of the broad side walls 1, 2.
- Figures 3 and 4 show in a horizontal section through the continuous casting molds according to Figures 1 and 2, which is created in the area of the casting level, the geometric conditions in this area of the continuous casting mold and their changes in a Format adjustment.
- the surface of the liquid melt filled into the continuous casting mold is referred to as the casting level, this casting level always being kept at approximately the same height in the continuous casting mold under constant casting conditions.
- FIGS. 3 and 4 only the inner edges of the broad side walls 1, 2 are shown in FIGS. 3 and 4.
- the centrally placed funnel-shaped pouring area 20 is adjoined on both sides by an adjustment area of the narrow side walls 21, 22, within which the narrow side walls 3, 4 are slidably positioned.
- the narrow side wall 4 is shown for a first strand format with solid lines and the broad side walls 1, 2 are also adapted to it with a solid line.
- the narrow side wall 3 is shown in the left half of the figure for a smaller strand format with dashed lines.
- the displacement movement of the narrow side wall 3 is indicated by the arrow 23, which symbolizes the narrow side adjusting devices 9, 10 from FIG. 1.
- the broad side wall 1 is designed as a loose side and in the direction of the arrow 24, which symbolizes the adjusting devices 12, 13 from FIG. 1, is tilted toward the fixed side formed by the broad side wall 2 and is shown pressed with dashed lines. The tilting movement takes place around the lower inner edge 18 of the broad side wall 1.
- the lower inner edge 18, which defines the outlet cross section from the continuous casting mold in a partial section, does not change its position due to the format adjustment, so that, regardless of the desired strand formats, the strand thickness in the outlet cross section is always constant remains. 5, the change in position of the broad side wall 1 caused by the tilting movement around the lower inner edge 18 is shown with dashed lines.
- the flat inner wall parts of the broad side walls 1, 2, which have different inclinations from one another, are aligned with arcuate transitions R

This creates the best conditions for the formation of strand shells.
- FIGS. 7a and 7b The structural structure of the broad side of a continuous casting mold is shown schematically in FIGS. 7a and 7b.
- Each broad side wall 1, 2 is either detachably fastened directly to a support wall 7, 8 by screw connections (FIG. 7b), or with the interposition of a support wall 27, and both walls are releasably fastened together on a support wall 7, 8 (FIG. 7a) .
- Coolant channels 26 are groove-shaped, parallel to each other and vertically following the pouring direction into each broad side wall 1, 2. However, they can also be incorporated into the support wall 7, 8 or support wall 27 lying against the broad side wall, as previously described for the broad side wall. This variant is shown in FIGS. 7a and 7b with dashed lines.
- the geometry of the coolant channels 26 differs in cross section and / or in their spacing from one another in the funnel-shaped pouring area from the adjustment area of the narrow side walls.
- the same effect can be achieved if the coolant channels 26 are connected in groups to coolant supply stations 28, as a result of which the flow rate in the coolant channels 26 becomes variable.
- the broad side walls 1, 2 are parabolic in the funnel-shaped pouring area 20 in the casting direction 6 (FIG. 8).
- the narrow side walls 3, 4 have a surface contour that is parabolic, in particular on the pouring side is formed and, in addition, edge clearances 30 are arranged on both sides in a region 29 which extends below the casting level to the mold outlet.
