Definitions

  • the invention relates to a mold plate with the features in the preamble of claim 1 and a mold with such a mold plate.
  • Mold plates made of copper are used in continuous continuous casting, especially in thin slab continuous casting plants.
  • the copper molds which consist of several mold plates, are usually fastened with various fastening elements, usually with screws, to a water tank required for cooling or to a support plate.
  • the fastening elements are fastened to fastening points on the back of the mold plate, as is the case, for example, in the US 2010/0 155 570 A1 will be shown.
  • the JP 2006-320 925 A1 suggests cooling channels at the foot of the fastening bolts. So-called spacers between the mold plate and the piece plate are also used in order to direct the cooling water into certain paths ( JP 2009-56 490 A ). From the JP H08 5237 A it is known to introduce the cooling channels from the back not only at a right angle to the back, but at an angle deviating from 90 ° to the back of a mold plate. As a result, the cooling channels run from the back to the hot side kind of weird. The width of the cooling channels remains constant.
  • the aim is to reduce the number of fastening elements and / or their size.
  • cooling water is brought close to the fastening points, ie usually to threaded inserts for receiving expansion screws.
  • additional cooling channels can be introduced between the fastening points in order to achieve a uniform cooling efficiency over the entire mold surface.
  • the cooling channels can be routed in a serpentine pattern around the attachment points. It is also known to provide more complex deep holes in funnel mold plates which carry out the cooling water below the fastening points near the pouring side.
  • the minimization of the size of the fastening points is limited by the strength of the copper and the fastening material.
  • the cooling channels leading around the fastening points cause a more homogeneous heat distribution between the fastening points, but cannot prevent the hot spots in the area of the fastening points themselves.
  • Cooling holes that run between the fastening points and the pouring side are associated with high manufacturing costs. Each deep hole must be closed separately with a plug, which involves the risk of leakage. In addition, they need supply wells that carry the cooling water. The various bores generally result in considerable pressure losses. In addition, the cleaning effort should not be underestimated due to the difficult accessibility.
  • the object of the invention is to provide a mold plate which, without structural weakening, makes it possible to reduce hot spots without increasing the production outlay due to complex deep drilling. A corresponding mold with better properties is to be shown.
  • a mold is the subject of claim 9.
  • the mold plate according to the invention has a plurality of fastening points on its rear side.
  • Attachment points in the sense of the invention are primarily attachment points that can absorb a force perpendicular to the mold plate. In particular, it concerns screw connections. Due to the relatively low strength of copper, threaded inserts are preferably introduced at the fastening points. The threaded inserts are in turn surrounded by the material of the mold plate.
  • a fastening point in the sense of the invention is also a receptacle into which a feather key or a alignment pin can be inserted in order to fix the position of the mold plate. Attachment points are used for Coupling the mold plate either with a water box or with a rear support plate.
  • Cooling channels in the form of depressions open to the rear are arranged in the rear of the fastening plate.
  • the cooling channels preferably run in the casting direction of the metal strand to be cooled, i. H. from top to bottom.
  • at least one cooling channel extends from the point of view of an attachment point to its casting side of the mold plate opposite the rear side, below the attachment points. From the point of view of the fastening point, this means that the fastening point including its wall made of the material of the mold plate is projected perpendicularly onto the plane of the casting side.
  • the heat dissipation can already be improved by a cooling channel extending on one side of an attachment point to below the attachment point.
  • the mold plate according to the invention can also be designed such that cooling channels extend on both sides of an attachment point to below the attachment point. In a way, it becomes a constriction below the attachment point created, which is particularly symmetrical. Geometrically, it is an undercut from the back. From a functional point of view, it is a widening of the bottom of the cooling channel.
  • cooling slots running in the longitudinal direction of the cooling channels are formed in the cooling channels.
  • the cooling slots expand the cooling channel and are part of the cooling channel.
  • At least one cooling slot is formed in a side wall of the cooling channel and extends under at least one attachment point.
  • a cooling duct in the sense of the invention has two opposite side walls connected by a floor.
  • the bottom is the back of the pouring side and runs at a distance from the back of the mold plate.
  • the side walls are partly formed by the attachment points.
  • the cooling slots further reduce the thickness of the mold plate or the distance of the cooling water from the casting side in some areas without weakening the structure of the mold plate as a whole.
  • the cooling slots are therefore smaller areas of the cooling channel. They are made with smaller machining tools, especially with side milling cutters or end mills. This makes it possible to form cooling slots, in particular in the corner region between the side wall of the cooling channel and a bottom of the cooling channel facing the casting side of the mold plate. Depending on the width of the cooling channel, this area is relatively difficult to access.
  • cooling slots make it possible to cool these thermally highly stressed areas of the mold plate better, by bringing the cooling water closer to the individual hot spots without weakening the structure of the mold plate.
  • the cooling slots in particular have a constant cross section and are free of flow shadows between an inlet of the cooling slot and an outlet of the cooling slot.
  • a cooling slot which extends to below an attachment point, can in particular be produced by a disk milling cutter, so that the cross section of the cooling slot remains the same over its entire length due to the manufacturing process.
  • the constant cross-section should be emphasized in particular because the cross-section does not have to be constant in the remaining areas of the larger cooling duct from which the cooling slot branches off.
  • the attachment points are namely preferably arranged in webs, which are also part of the side walls of cooling channels. The attachment points are slightly weakened by the constriction in their foot area, but the attachment points are held by webs. The webs support the column-like protruding fastening points.
  • the webs and the cooling channels run parallel to one another, the webs between the fastening points being substantially narrower in cross section than the fastening points.
  • the cross section of the cooling channels is therefore not constant in the flow direction due to the shape of the alternating webs and fastening points, while the cross section of the cooling slots remains constant. This enables continuous and homogeneous cooling in the base area of the fastening points.
  • inserts can be inserted into the cooling channel open to the rear of the mold plate. These inserts can cover the cooling slots and thereby increase the flow speed in the area of the cooling slots. This measure can contribute to a homogeneous, uniform and efficient cooling over the entire casting surface. In particular, dead zones caused by flow shadows in the cooling channel are completely avoided by the inserts.
  • the advantages of the invention come into play in particular when all the fastening points of the lateral widenings of the cooling channel are undercuts at least in some areas. However, it is also possible to cool only those fastening points that are exposed to particularly high thermal loads. Fastening points in the mold level of the mold benefit as much as possible from the additional cooling of the hot spots.
  • the invention has the advantage that the mold plate, which expands under casting conditions, enables a very thin-walled coupling of the fastening points due to the special cooling channel geometry. This in turn results in lower material stresses in the mold plate, so that correspondingly smaller-sized thread inserts can be used in the fastening points. It has been shown that mechanical reduction of the structural strength due to the thin-walled connection, but this can be compensated for as a result of improved, ie more uniform cooling, because locally higher heat strengths can be achieved at lower temperatures. Bending moments caused by thermal conditions are smaller than would have been expected since the temperature differences can be significantly reduced by the optimized cooling.
  • the invention relates not only to a single mold plate, but also to a complete mold comprising mold plates as described above.
  • a mold is used for the continuous continuous casting of thin slabs.
  • narrower mold plates are provided on the narrow sides of the mold cross-section to be limited, over which the mold plates described above are spaced.
  • These narrower mold plates can also be equipped on their rear side with corresponding cooling channels, with at least one cooling channel extending from the point of view of a rear attachment point of the narrow side mold plate to its casting side of the mold plate opposite the rear side, below the attachment point.
  • the arrangement and design of the cooling channels can be carried out analogously to the design of the rear sides of the larger mold longitudinal plates.
  • the interior tapers in a funnel shape between the mold plates. While the casting side of the mold plate has a rounded contour, the back of the mold plate has a number of longitudinal cooling channels to effectively cool the mold plates and to avoid the hot spots in the area of the attachment points with a water tank or a rear support plate .
  • Figure 1 shows a sectional view through a mold plate 1.
  • the cutting plane runs in the horizontal direction.
  • the mold plate 1 is shown in perspective from the rear, with only a partial area of a longitudinal edge and the rear of the mold plate being visible.
  • the back 2 of the mold plate 1 is the back plane in which a plurality of fastening points 3 are arranged.
  • the attachment points 3 are provided for connecting the mold plate 1 to a water tank (not shown in more detail) or to a support plate.
  • the fastening points 3 have threaded inserts which are inserted into bores in the rear 2 of the mold plate 1.
  • the side of the mold plate 1 opposite the rear side 2 is the casting side 4, via which a strand of metal to be cooled is cooled.
  • a plurality of mold plates 1 delimit a format cross section of a generally rectangular casting strand in a manner not shown in detail.
  • the mold plate 1 is cooled with water, which is passed through cooling channels 5, which are in the image plane of the Figure 1 extend from top to bottom, parallel to a long side 6 of the mold plate 1.
  • the cooling channels 5 run parallel to one another and are open in the form of essentially rectangular depressions toward the rear 2 of the mold plate 1.
  • the cooling channels 5 are separated from one another via narrow webs 7.
  • the webs 7 connect two adjacent or successive fastening points 3 to one another.
  • the wall thickness of the webs 7 between the fastening points 3 is considerably less than below a fastening point 3, as can be seen from the position of the cutting plane.
  • the one in the section plane of the Figure 1 middle attachment point 3 is configured in a column-like manner and has a cross section that is constant over its predominant length range. This length range is wider than the web 7 adjoining it.
  • a milling tool 8 in the form of an end mill illustrates that constrictions are produced in the base area of the fastening points 3.
  • the constrictions are symmetrical. They lead to widening of the cooling channel 5 in the area of its bottom 9.
  • the bottom 9 of the cooling channels 5 is not flat overall, but has a plurality of cooling slots 10, 11, 12, which are each separated from one another by webs 13, 14 running parallel to one another.
  • the three cooling slots 10, 11, 12 have a constant cross section.
  • the cooling slots 11, 12 arranged at the edge of the base 9 form undercuts from the point of view of the fastening points 3 and, from the point of view of the fastening points 3, engage under the fastening points 3 in the direction of the pouring side 4.
  • an area of the casting side 4 designated with HS is identified as a so-called hot spot.
  • Such hot spots HS are located on the pouring side 4 below each fastening point 3, because in this area the heat from the pouring side 4 has hitherto been insufficiently dissipated from the coolant.
  • the area of the hot spot HS is geometrically reduced in the invention by the cooling channels 5 widened in the base area or the cooling slots 11, 12 arranged there, and also by improved cooling.
  • the cross section in the area below the fastening points 3 is reduced by approximately 50%.
  • the cooling slots 12 have a constant cross section, so that cooling water can be guided past the hot spots HS at a high flow rate and can very effectively dissipate the thermal energy from these areas. From a thermal point of view, the hot spots HS are significantly smaller. The temperature fluctuations on the casting side 4 are significantly lower.
  • FIG 2 shows the same mold plate 1 as in Figure 1 .
  • inserts 15 are inserted into the cooling channels 5 from the rear 2. It can be seen that the inserts 15 are supported on the webs 13, 14 and extend in height to the rear 2.
  • side parts 16, 17 which are adapted to the contour of the webs 7 and the side walls 18 of the cooling channels 5.
  • the flow rate within the cooling slots 10, 11, 12 is significantly increased by the inserts 15.
  • the side parts 16, 17 extend to the rear 2 of the mold plate 1, so that they rest securely against the webs 13, 14 on the bottom 9 of the cooling channels 5 even under the pressure of the coolant and the flow guidance is reliable guarantee.
  • the base areas of the fastening points 3 are effectively cooled.
  • Figure 3 shows a perspective view of a mold 19.
  • the mold 19 has two opposing mold plates 1 according to the above embodiment.
  • the two mold plates 1 are spaced apart and form a mold cavity 20 which tapers in the center in the casting direction in the form of a funnel.
  • the narrow sides of the mold cavity 20 are delimited by narrow side plates 21.
  • the mold plates 1 in combination with the narrow side plates 21 thus limit the format cross section of a casting strand which is rectangular at the outlet end of the mold 19.
  • the two mold plates 1 are configured identically.
  • a complete back 2 of the mold plate 1 can be seen, in which the inserts 15 can also be seen.
  • the inserts 15 are held partly via screw connections 22 and partly via clips 23 on the rear side 2.
  • the mold plates 1 are screwed to a water box (not shown in more detail) or to a support plate.
  • the inserts 15 are then also supported on the water tank or the support plate.
