Abstract
Description
[0001] The present invention relates to a baffle pot made of refractory material for use in a distributor of a continuous casting plant for molten metal, having at least one base plate and at least one first side wall arranged on the base plate, wherein the base plate and the first side wall define an interior space for receiving a molten metal and wherein the baffle pot has an inlet opening on its upper side through which molten metal can enter the interior space.
[0002] In the metallurgy industry, impact pots are used to calm the flow of molten metal, especially molten steel, in continuous casting plants. Typically, the molten metal is poured from a ladle into a tundish. The tundish serves as a buffer for the molten metal, ensuring no interruptions during the continuous casting process and distributing the molten metal among the individual strands of the continuous casting plant.
[0003] To prevent reoxidation of the molten metal due to contact with ambient air, the surface of the molten metal in the tundish is typically covered with a covering agent, such as a covering powder. The covering powder forms a slag on the molten metal, thereby preventing contact with the ambient air.
[0004] The molten metal has a comparatively low viscosity and a high density. Furthermore, there is a height difference between the pouring ladle and the tundish floor. If the molten metal were poured directly from the pouring ladle into the tundish, it would impact the tundish floor at high speed and with high kinetic energy. This would pose the risk of damaging the tundish's refractory lining and causing refractory inclusions in the molten metal.
[0005] To prevent this, a so-called impact pot can be inserted into the tundish, and the pouring ladle is positioned over the impact pot before the molten metal is poured out, so that the molten metal first hits the impact pot during pouring. This protects the lining of the tundish and calms the flow of the melt. However, there is a risk that the molten metal could splash out of the impact pot and injure nearby people or damage machinery.
[0006] Impact pots are usually made of fireproof ceramic.
[0007] An impact pot is known, for example, from DE 10 2007 035 452 A1. This previously known impact pot comprises a base plate and a side wall oriented perpendicular to the base plate. The base plate and side wall enclose an interior space and each have a surface facing the interior space. The surfaces have a surface structure in the form of projections, openings, or recesses. Due to the surface structure, the molten metal, when impacting and rebounding against the surface, receives virtually no velocity component that directly opposes the incoming jet of molten metal, which is intended to calm the pouring process and the flow of the molten metal.
[0008] Another impact pot is known from US 9,889,503 B2. The impact pot disclosed therein has a base portion and two walls extending upwards from it. The walls have the shape of a C, U, V, W, E, or a 3 in plan view and are arranged relative to one another in such a way that outflow channels for the molten metal are formed between them. As a result, the molten metal flows in a meandering pattern out of the impact pot into the distributor.
[0009] There is still a need to improve the flow conditions when pouring the molten metal into the tundish.
[0010] The object of the present invention is therefore to provide an impact pot with which the flow when pouring molten metal into a distributor of a continuous casting plant is further optimized.
[0011] This object is achieved according to the invention with a baffle pot of the type mentioned at the outset according to claim 1 in that the baffle pot has a lid having the inlet opening with a second side wall which, together with the first side wall, forms at least one flow guide for the molten metal in such a way that the molten metal which has entered the interior is guided in an upward or downward movement between the first side wall and the second side wall when flowing out of the baffle pot.
[0012] The object is further also achieved by the use of an impact absorber according to the invention according to claim 20.
[0013] The impact pot according to the invention has at least one flow guide through which molten metal is guided from the interior into the distributor. With the flow guide, the molten metal can be guided in an upward or downward motion such that an exit plane of the molten metal lies below the inlet opening of the impact pot. The molten metal can thus flow into the distributor below a molten metal level already present in the distributor, so that it does not come into contact with the surface of the molten metal in the distributor. In this way, the sinking of covering powder or slag from the surface of the molten metal in the distributor can be prevented, and contamination of the molten metal can be avoided.
[0014] By guiding the molten metal in an upward or downward motion, the flow path of the molten metal can be extended as it flows out of the impact pot. This advantageously removes kinetic energy from the molten metal, reducing the turbulence of the molten metal in the distributor as it flows out.
[0015] The lid of the impact pot according to the invention also deflects the molten metal within the interior and / or as it flows from the interior into the flow guide, thereby exerting a braking effect and also removing kinetic energy from the molten metal flowing into the impact pot. Furthermore, the lid prevents molten metal impacting the base plate from splashing upwards out of the interior or the impact pot. Instead, the incoming molten metal is already calmed down in the interior to such an extent that, upon reaching a certain fill level, it flows almost entirely into the flow guide and from there out of the impact pot due to further molten metal entering the interior.
[0016] The size of the inlet opening in the cover typically corresponds to the size of the inlet opening of conventional impact pots and is naturally dimensioned such that, with a given positioning accuracy of a pouring ladle above the impact pot, the molten metal flow from the pouring ladle can flow unhindered from the cover into the impact pot. At the same time, the size of the inlet opening should also be dimensioned in relation to the overall size of the impact pot to ensure a sufficient deflection or braking effect on the molten metal in the impact pot and, preferably, also to protect against molten metal splashing out of the impact pot.
[0017] The impact pot can also have one or more separate flow guides. Depending on the volume flow that is to be discharged from the impact pot, the impact pot can have two, three, four, or more flow guides.
[0018] Preferably, surfaces of the first side wall and the second side wall that face each other and form the flow guide run parallel to each other at least in sections, at least in a horizontal cross-section. In principle, the flow guide should ensure an upward or downward flow, which is preferably but not necessarily vertical. In principle, it is also possible for the flow guide to be designed such that the molten metal is guided, at least in one section of the flow guide, at an angle to the vertical of preferably 0° to 10° or in a larger angular range of 0° to 45° or even in an arc. In particular, if the molten metal exits the flow guide into the distributor in an upward flow, a flow direction that is inclined to the vertical can be advantageous.By selecting the exit angle of the molten metal flow from the flow guide into the impact pot, the flow conditions in the distributor can be influenced.
[0019] In one embodiment, the flow guide is formed by mutually facing surfaces of the first and second side walls, which are spaced apart by a distance T. The distance T is small compared to a width B of the flow guide, wherein the ratio of distance T to width B is preferably not greater than 1:2 and particularly preferably not greater than 1:5, 1:10 or 1:20. The distance T is the greatest distance along a surface normal on the inner of the mutually facing surfaces of the side walls forming the flow guide, which is closer to the center of the interior space. The width B is the length of a horizontal line running through the surface normal and running along this inner surface.
[0020] By correctly selecting the width and spacing or depth of the flow guide, the flow of the molten metal can be influenced to positively influence the flow conditions of the molten metal within the distributor. At the same time, the impact pot can be designed compactly with the flow guide(s) in the edge area.
[0021] In a further embodiment, the first side wall and the second side wall are each designed to be circumferential, whereby all molten metal flowing out of the impact pot is guided in the flow guide. However, it is also conceivable and could be advantageous, for example, depending on the geometry of the distribution channel, for one of the two side walls, in particular the outer one, to be non-circumferential, in which case the one or more flow guides do not extend around the entire impact pot.
[0022] Furthermore, the flow guidance can also be designed to be circumferential, which allows particularly large volume flows to flow out of the interior.
[0023] The first side wall can form an angle of preferably 80° to 100° with the base plate toward the interior. Preferably, the angle is exactly 90°, so that the first side wall is oriented perpendicular to the base plate. However, the angle of the surface of the first side wall facing the flow guide can also be more steeply inclined, preferably in a range of 0° to 45°, to the vertical, particularly when the second side wall is arranged in the interior of the impact pot.
[0024] In one embodiment, the impact pot has one or more spacers, which can be arranged between the first and second side walls, in particular at different locations. In particular, the spacers can be formed on the first and / or second side walls. The spacers ensure that the side walls are spaced apart in the region where the flow guide is formed, and that the molten metal can flow unhindered. Preferably, the first and second side walls can also be connected to one another via the spacers.
[0025] In a further development, the spacers extend over at least part of the height of the flow guide and thus limit it laterally. In particular, the spacers extend over the entire height of the flow guide. The height of the flow guide is understood to be a dimension that extends vertically when the impact absorber is installed.
[0026] Preferably, the cover extends from the second side wall over the interior space in such a way that the cover covers part of the interior space. The cover can advantageously cover the interior space to such an extent that the inlet opening is no larger than necessary for a maximum incoming volume flow of molten metal. By at least partially covering the interior space, not only is the molten metal entering the interior space prevented from splashing out of the inlet opening again due to impact with the base plate. In addition, in certain designs of the impact pot, the molten metal can be prevented from impacting an upper edge of the first side wall, which would lead to increased wear of the impact pot.
[0027] The lid can be at least partially plate-shaped, particularly in an area where it covers the interior. However, it is also conceivable for the lid to have, at least partially, the shape of a hemisphere, a dome, or a cone, among other things.
[0028] In a further embodiment, the lid rests on an upper side of the first side wall. For this purpose, the first side wall can, for example, have one or more support surfaces on its upper side.
[0029] In a specific embodiment, the second side wall is arranged outside the interior space. In this case, the flow guide is formed by a surface of the first side wall facing away from the interior space and a surface of the second side wall facing the interior space. In this embodiment, at least one recess can also be provided in an upper region of the first side wall, in particular on the upper side, via which recess the interior space is connected to the flow guide. This is particularly advantageous when the lid rests on an upper side of the first side wall. If the recesses are arranged on the upper side of the first side wall, the side wall has a lower height in these regions than in the other regions, as a result of which the metal melt flows from the interior space over the edge of the recesses into the flow guide.
[0030] In another specific embodiment, the second side wall is arranged within the interior space. In this case, the flow guide is formed by a surface of the first side wall facing the interior space and a surface of the second side wall facing away from the interior space. In a further development, the second side wall can have at least one foot section with which it stands on the base plate. Preferably, the second side wall has two, three, four or more foot sections. Furthermore, in this embodiment, at least one flow opening can be provided in a lower region of the second side wall, in particular on an underside facing the base plate. The interior space is connected to the flow guide through the flow opening in such a way that molten metal can flow from the interior space into the flow guide.
[0031] In a further embodiment, the impact pot has a third side wall. The third side wall forms an additional section of the flow guide, either with the first side wall or with the second side wall. Through the additional section of the flow guide, the molten metal can be guided, for example, first in an upward and then downward movement, or vice versa, as it flows out of the interior. In particular, the flow guide through the additional section forms a substantially U-shaped guide for the molten metal. The additional section further lengthens the flow path of the molten metal, causing it to lose further kinetic energy.
[0032] The third side wall can, for example, be arranged on the base plate. In this case, it forms the additional section of the flow guide with the second side wall. Alternatively, the third side wall can also be arranged on the cover, in which case it forms the additional section with the first side wall.
[0033] The impact absorber according to the invention can be constructed in one or more parts. In one embodiment, the impact absorber is constructed in two parts, with the base plate and the first side wall forming part of a first impact absorber part, and the cover with the second side wall forming part of a second impact absorber part.
[0034] In the two-part design of the impact absorber, the first and second impact absorber parts can be firmly connected to one another by connecting means. Connecting means can be provided that form a permanent connection or those that form a detachable connection, for example for maintenance purposes. In particular, several, in particular four, through holes are provided on the first side wall and on the second side wall, wherein the through holes in the first side wall are aligned with the through holes in the second side wall when the impact absorber parts are arranged accordingly. In particular, ceramic bolts can be inserted into the through holes as connecting means and fixed, for example, with mortar. The use of pins or screws as connecting means is also conceivable.
[0035] In a further embodiment, the base plate of the impact absorber can have a round, in particular circular, base area. However, the base area can also be rectangular, in particular square, instead. Accordingly, all side walls can also have a round, in particular circular, or rectangular, in particular square, horizontal cross-section. The choice of a suitable shape for the impact absorber results in particular from the shape of the distributor and the position of the strands leading from the distributor in relation to the arrangement of the impact absorber in the distributor.
[0036] Furthermore, the first and / or second side walls of the impact pot can have a plurality of projections. In particular, the side walls have the projections on the surfaces facing the flow guide. Since the projections extend into the flow guide in this way, the flow path of the molten metal from the interior into the distributor is extended, thereby removing further kinetic energy from the molten metal.
[0037] Advantageously, a plurality of projections are provided, arranged in several horizontally aligned rows and distributed over the entire surface or surfaces of the first and / or second side wall. The projections are in particular in the shape of a prism with a trapezoidal base. However, the projections can also be in the shape of a rectangle, square, or truncated cone.
[0038] As a result, the impact pot according to the invention makes it possible not only to slow down and calm the molten metal flowing in from a pouring ladle and to minimize uncontrolled splashing out of the impact pot, but also to specifically influence the flow of the molten metal in the distributor by means of a flow guide designed for this purpose.
[0039] Furthermore, a use of the impact pot according to the invention and described above in a distributor of a continuous casting plant for calming the flow of molten metal is claimed. In the following, the inventions are explained in more detail using several embodiments and associated figures: It shows Fig. 1a: a sectional view of a side view of an impact absorber according to the invention according to a first embodiment; Fig. 1b: a perspective view of the first impact pot part of the first embodiment; Fig. 1c: a perspective view of the second impact pot part of the first embodiment; Fig. 1d: an exploded view of the impact absorber according to the first embodiment; Fig. 2a: a sectional view of a side view of an impact absorber according to the invention according to a second embodiment; Fig. 2b: an exploded view of the impact absorber according to the second embodiment; Fig. 3: a sectional view of a side view of an impact absorber according to the invention according to a third embodiment; Fig. 4: a sectional view of a side view of an impact absorber according to the invention according to a fourth embodiment; Fig. 5: an exploded view of an impact absorber according to the invention according to a fifth embodiment; Fig. 6: an exploded view of an impact absorber according to the invention according to a sixth embodiment.
[0040] The Fig. Figure 1a shows a sectional side view of an impact absorber 1 according to the invention. The impact absorber 1 is designed in two parts with a first, Fig. 1b shown in more detail impact pot part 2 and a second, in Fig. 1c shows the impact pot part 3. The first impact pot part 2 has a base plate 4 and a first side wall 5, which together define an interior space 6. The interior space 6 serves to accommodate molten metal. The base plate 4 has a circular base. The side wall 5 is circumferential and also has a circular horizontal cross-section. The surface 5.2 of the side wall 5 facing the interior space 6 is oriented vertically, while the outward-facing surface 5.1 is slightly inclined upwards toward the interior space 6.
[0041] The second impact pot part 3 consists of a cover 7 with a second side wall 8. In the cover 7, an inlet opening 9 is provided for the entry of molten metal into the interior 6. The inlet opening 9 is located centrally above the interior 6, with the cover 7 covering part of the interior 6 with a plate-shaped section. With the plate-shaped section, the cover 7 sits on two Fig. 1b, the first side wall 5 has support surfaces 10. The second side wall 8 is arranged outside the interior space 6.
[0042] The first and second side walls 5, 8, with their mutually facing surfaces 5.1, 8.1, form a flow guide 11.1 with an outlet opening 12. The flow guide 11.1 guides the molten metal in a substantially vertically downward motion as it flows out of the interior space 6. The outlet opening 12 is located significantly below the cover 7 and the inlet opening 9 of the impact pot 1.
[0043] The mutually facing surfaces 5.1, 8.1 of the first side wall 5 and the second side wall 8 extend essentially parallel to one another over the entire height H of the flow guide 11.1 in horizontal cross-section E. On its upper side 13, the first side wall 5 has a recess 14.1, via which the flow guide 11.1 is connected to the interior space 6 and whose width corresponds to the width B (see Fig. 1b) corresponds to the flow pattern 11.1. The width B runs through the surface normal 16. In addition, Fig. 1c, a maximum distance T is created on the second side wall 8 between the facing surfaces 5.1 and 8.1, which extends along the surface normal 16. The distance between the facing surfaces 5.1 and 8.1 is reduced by the slight inclination of surface 5.1 of the first side wall 5 in the direction of the outlet opening 12. The spacers 15 extend over the entire height H of the flow guide 11.1. The flow cross-section of the flow guide 11.1 is thus determined from its width B and the distance T. Width B and depth T can be varied structurally within a wide range. The resulting flow cross-section and / or the number of flow guides must be selected such that the molten metal flowing from the pouring ladle into the impact pot in a continuous casting plant can flow essentially completely through the one or more flow guides.At the same time, the flow cross-sections of one or more flow guides must be selected to achieve the desired deceleration effect on the molten metal. Depending on the arrangement of a baffle pot in a distributor, it may be advantageous if the flow cross-sections of individual flow guides differ from one another in order to influence the flow of the molten metal to the individual strands leading from the distributor.
[0044] The impact pot 1 also has a second flow guide 11.2 opposite the first flow guide 11.1. The two flow guides 11.1, 11.2 are designed separately from each other. The second flow guide 11.2 is designed analogously to the first flow guide 11.1 and is therefore not described in detail below.
[0045] The impact pot 1 can be mounted with its base plate 4 in a tundish (not shown) in a known manner. When molten metal is poured from a pouring ladle through the inlet opening 9, it initially impacts the base plate 4 and collects in the interior space 6. The partial coverage of the interior space 6 by the cover 7 prevents the molten metal from splashing out of the inlet opening 9 due to the strong flow and turbulence. Furthermore, the coverage also ensures that the molten metal does not impact the upper side 13 of the first side wall 5 and cause long-term wear.
[0046] As soon as the level of the molten metal exceeds the lower edge of the recesses 14.1, 14.2, the molten metal flows via the recesses 14.1, 14.2 of the first side wall 5 into the flow guides 11.1, 11.2 and then flows downwards through the outlet openings 12 into the distributor (not shown). This guidance of the molten metal, on the one hand, calms the flow of the molten metal so that it does not splash when exiting the impact pot 1. On the other hand, the molten metal can flow out below a fill level of molten metal already present in the distributor. This prevents slag or covering powder on the surface of the molten metal contained in the distributor from being introduced into the molten metal below by molten metal from the impact pot.
[0047] As in Fig. As shown in Figure 1d, the first impact pot arrow 2 and the second impact pot part 3 can be firmly connected to each other by connecting means via the spacers 15. For this purpose, the impact pot parts 2, 3 each have four through holes 17.1, 17.2 in the side walls 5, 8, of which Fig. 1d shows three through holes 17.2 of the second impact absorber part 3. The impact absorber parts 2, 3 are arranged such that the through holes 17.1, 17.2 are aligned with each other. A connecting element in the form of a bolt 18, which, like the other parts of the impact absorber 1, is preferably made of ceramic material, can be inserted into two corresponding through holes 17.1, 17.2 and fixed with mortar. Instead of constructing the impact absorber 1 in two parts, it can also be constructed in one part, in which case such connecting elements can be dispensed with.
[0048] The Fig. 2a and Fig. 2b show a second embodiment of the impact pot 1 according to the invention. In contrast to the embodiment shown in Fig. In the embodiment shown in Figures 1a to 1d, in addition to the first side wall 5 and second side wall 8, a circumferential third side wall 19 is provided. The third side wall 19, like the first side wall 5, is arranged on the base plate 4 and is oriented substantially perpendicular to the latter. The first side wall 5 and the third side wall 19 are arranged at a distance from one another, with the second side wall 8 being partially arranged between them. In this way, the mutually facing surfaces 5.1, 8.1, 8.2, 19.1 form a substantially U-shaped flow guide 11.1. The second flow guide 11.2 is also U-shaped. Since the molten metal in this embodiment has to travel a longer distance when flowing out of the impact pot 1 due to the U-shape of the flow guides 11.1, 11.2, and flows both upwards and downwards, the flow of the molten metal can be even better calmed.
[0049] As in Fig. As can be seen in Figure 2b, the third side wall 19 has recesses 20 through which the molten metal flows from the flow guides 11.1, 11.2 into the distributor. The lower edge of the recesses is located significantly below the top of the cover to allow the molten metal from the impact pot to flow into the distributor below the molten metal level in the distributor.
[0050] Fig. Figure 3 shows a third embodiment of the impact pot 1 according to the invention, which differs from the one shown in Fig. 1a to 1d in that the base plate 4 of the first impact absorber part 2 has a square base. The cover 7 also has a corresponding square outline.
[0051] Fig. Figure 4 shows a fourth embodiment of the impact absorber 1 according to the invention. In this embodiment, the second side wall 8 is arranged partially within the interior space 6 defined by the base plate 4 and the first side wall 5. The flow guide 11.1 formed by the mutually facing surfaces 5.1, 8.1 of the first and second side walls 5, 8 is therefore also located within the interior space 6. As in the embodiment shown in the Fig. 1a to 1d, two flow guides 11.1, 11.2 are also provided in this embodiment.
[0052] On the second side wall 8, foot sections 21 are provided, with which the second side wall 8 or the second impact pot part 3 rests on the base plate 4. In the sections outside the foot sections 21, flow openings 22 are formed through which molten metal can flow into the flow guides 11.1, 11.2. In this embodiment, the upper edge of the first side wall 5, which defines the minimum exit height of the molten metal from the impact pot 1, lies significantly below the top side of the cover 7 of the impact pot 1. Here, too, the molten metal can thus exit the impact pot below the molten metal level in the distributor.
[0053] Fig. Figure 5 shows a fifth embodiment of the impact absorber according to the invention, which differs from the one shown in Fig. 4 in that the impact pot 1 has a total of four flow guides 11.1, 11.2, 11.3, 11.4.
[0054] A total of four foot sections 21 are therefore provided, each extending over a significantly smaller section of the second side wall 8 compared to the foot sections of the fourth embodiment. Compared to the fourth embodiment, this embodiment allows larger volume flows to flow from the interior 6 into the distributor.
[0055] The Fig.6 shows a sixth embodiment, which is a further development of the fifth embodiment. In this embodiment, a plurality of projections 23 are provided on the surfaces 5.1 of the first side wall 5 forming the flow guides 11.1, 11.2, 11.3, 11.4. The projections 23 each have the shape of a prism with a trapezoidal base and protrude into the flow guides 11.1, 11.2, 11.3, 11.4. In this embodiment, the plurality of projections 23 further calms the molten metal flow. The feature of the projections 23 of the sixth embodiment is not limited to a further development of the fifth embodiment, but can also be provided in embodiments one to four.
