Definitions
- the invention relates to a method for producing thin slabs with a predetermined crowning of their broad sides in a continuous casting installation, in which an immersion spout protrudes into a mold, which is followed by a strand guide, and a corresponding device for carrying out the method.
- a liquid-cooled, width-adjustable plate mold for the continuous casting of steel strands in slab format is known, in particular for a thickness of the slabs below 100 mm, in which the shape of the broad side plates at the strand exit end of the mold corresponds to the strand format to be produced, the Broad side plates are designed as a flat surface in the adjustment area of the narrow side plates.
- the strand exit side of the mold faces the larger curved cross section on the pouring side and at least one roller of at least one pair of rollers of the support and guide means arranged downstream of the mold has a caliber adapted to the emerging curved strand.
- the mold shape known from this document as well as the shape of the support and guide means arranged downstream of the mold, are designed in such a way that the mold has a shape adapted to the strand format in the edge region, that is to say There are already parallel side wall areas in the mold, which continue with the support and guide rollers of the strand guiding framework
- the concave shape of the broad side plates known from this document relates to a relatively complicated shape which is essentially influenced by the deflection of the roller and the current wear
- the invention aims to provide a continuous casting device with a mold and strand guide rollers with simple structural means, which reduce the load on the strand shell and minimize the risk of longitudinal cracks and breakthroughs.
- the mold broad sides are largely composed of flat surface parts and the strand guide rollers have a contour that is composed essentially of straight lines.
- a flat surface is provided in the central area, which is maintained in the strand guiding direction and is completely taken over by the central parts of the guide rollers beyond the mouth of the mold.
- Flat surfaces in the direction of the narrow sides are also provided on both sides of this flat central part. The shape and inclination of these flat surfaces are exactly maintained from the entrance of the mold to the end of the strand guide frame.
- Transition pieces are provided between the flat central surface of the mold and the flat side surfaces arranged on both sides. The extension of these transition pieces ends within the mold, so that the lower area corresponds to the strand format. In addition, this shape allows the cold strand to be introduced and removed easily when the continuous casting machine is cast on.
- the middle part is flat in the pouring area.
- the flat middle parts of both broad slab sides run in
- the strand direction tapers towards one another until they are guided within the mold, forming a so-called crown, parallel to the mouth of the mold.
- the central parts in the pouring area are flat and parallel and outside the shadow area of the Dipping spout in the strand guide direction by means of a connecting part with the central part having the "crown" in the mouth region of the mold.
- the central parts have a shape whose vertical lines are parallel to one another and whose longitudinal extension in the strand conveying direction is S-shaped. The mouth of this S-shape merges tangentially into the adjacent surfaces.
- the slab produced in a mold according to the invention has broad sides, which are composed of three flat surfaces, the side surfaces being conical and the central surface being raised compared to the edge region.
- This shape of the slab enables better centering of the slab, especially at the strand withdrawal speeds that are common today. This avoids uncontrolled movement of the strand in the mold and a so-called snaking in the strand guide frame.
- the outer shape of the strand shell of the slab thus produced remains absolutely constant at least up to the bottom of the sump.
- the only change to the slab is in the thickness direction, whereby only the narrow sides are deformed.
- the central mold width area namely the area designed as a trough, remains unchanged in its flat shape until it solidifies and ensures the most favorable lubrication conditions in the mold.
- the casting powder wets the strand surface in a definable amount in the area of greatest longitudinal crack sensitivity. Thanks to its flat shape, the strand shell is therefore not subject to any bending stress in this central mold width range, which favors the occurrence of cracks near the surface.
- a separate cooling medium guide has a special influence on the solidification conditions of the strand shells in the area of the transition parts and the connecting part.
- the subsequent strand guide scaffold has support and guide rollers which ensure safe transport of the slab, which still has a sump.
- different roll forms are proposed, namely complete rolls or split rolls.
- simple cylindrical rollers are used, which are adapted to one another in accordance with the configuration of the center or side surfaces of the slab shape specified by the mold
- the 2/3 role has a contour corresponding to the assignment of the middle part to the side part
- Figures 1 and 2 show in perspective a mold with a downstream strand guide
- the mold has broad sides 21, between which narrow sides 22 are clamped.
- the broad sides have a central surface 23 which is flat and runs from the entrance to the mold mouth
- the central parts are arranged parallel to one another with respect to their contour and run conically towards one another in the direction of the strand advance.
- the central parts 23 are connected to side parts 24 and 25 via transition parts 26 and 27
- transition parts 26 and 27 are wedge-shaped, the wedge tip 28 still being spaced within the mold at a distance from the mold entrance Adjustment elements 31 are provided on the narrow sides 22, by means of which the narrow sides 22 clamped between the broad sides 21 can be adjusted in order to change the slab format.
- Support and guide rollers 41 are provided below the mold.
- Split rollers 43-45 having a cylindrical shape are shown in the present example.
- b denotes the width of the middle part 23.
- the width b remains constant from the pouring area of the mold to the mold mouth.
- the side plates In the pouring area, the side plates have a width f, which widen to the width g following the conical transition part 26 or 27 and maintain this width constantly until the mouth of the mold.
- the central plate has a width c in the pouring area, which widens following the wedge-shaped transition parts 26, 27 in the continuous casting direction up to the length a of the mold to the width b and from there remains constant up to the mouth of the mold.
- the width f of the side plates 24 and 25 remains constant over the entire length L of the mold.
- a dip nozzle 1 which has a tubular part 12 and a rectangular part 14, projects into the mold. Its mouth 13 protrudes below the melt level S P (dashed line).
- FIG. 3 shows a section aa through the broad sides 21 of the mold.
- the flat center plate 23 In the left part of the figure, the flat center plate 23 is shown, which merges at a distance a into a straight area that is parallel to the opposite center plate. In the right part of the figure, a first section of the center plate 23 is guided flat and parallel to the center axis I. Connected to this parallel part with a tangential transition is a connecting part 29 which has an S-shaped shape in section and in turn merges into the parallel part of the center plate 23 in the direction of the mouth.
- the spade-shaped part 14 of the immersion spout 11 projects into the mold to below the melt level S P.
- the support and guide rollers 41 are shown below the mold.
- the dashed line represents the distance D s of the side plates 24 and 25, and thus also the narrow side of the slab.
- FIG. 4 shows a plan view of a broad side of the mold, together with the immersion spout 11 with its tubular part 12 and its rectangular part 14, as well as the mouth 13, which protrudes below the melt level S P.
- the side plate 24 is shown, which has a constant width g.
- the side plate 25 is shown, which has a width f in the entrance area of the mold, which has a width g conically following the conical transition part from the wedge tip 28.
- the center plate 23 has a constant width b with a view of the left side of the figure.
- the center plate 23 has a width c, which widens in accordance with the conical transition part 26 and has the constant width b from the wedge tip 28.
- rollers 43, 44 are shown below the mold. Immediately following the mold, a total of three rollers 43, 44 are shown in the present figure, each of which has a cylindrical shape and are inclined toward one another in accordance with the inclination of the sides and the central surface of the slab that produces it.
- the rollers shown in positions 3 and 4 of the stand consist of a 2/3 roller 46 and a cylindrical roller 44.
- the roller 46 has a cylindrical section and a conical part which is adapted to the inclination of the side surfaces.
- Positions 5 and 6 show rolls whose complete contour corresponds to the slab produced in the upstream mold, both in the middle area and in the side areas.
- FIG. 5 shows a section through the guide frame and the slab, which also has a sump in this area.
- the situation is shown with the opposing pairs of rollers in the central region 43 and in the side regions 44, 45. These rollers support the broad sides 51 of the shell box composed of the broad sides 51 and the narrow sides 52.
- the shell box envelops the melt S, which forms the sump within the slab in this area.
- Slab broad side 51 is supported, and which is adjoined in the right part of the image by a cylindrical roller 44 which supports the narrow side region.
- Mold device 21 mold broad sides
