Definitions
- the invention relates to a method for connecting a new casting strand in a continuous caster with an intermediate container (tundish) for the liquid casting metal, which is provided in the bottom with an outlet opening which can be closed by a closure means, and with a cooled continuous casting mold arranged below the outlet opening with mold inlet, mold cavity and lower mold outlet, and, if appropriate, with one between the outlet opening and mold arranged dip tube protruding into the mold cavity, in which (process) the mold outlet is at least largely temporarily closed and, after opening the slide closure by solidifying the casting metal which first emerged from the outflow opening, a connection is made to the end of a cold strand provided with connecting means, whereupon the cold strand is pulled off with the connected casting strand.
- the invention also relates to a corresponding arrangement for performing such a method.
- the casting mold In continuous casting, the casting mold not only serves to form a certain cross-sectional shape of the casting strand, but because it is cooled, the molten metal solidifies in the peripheral region of the strand to form a so-called strand shell, the presence of which continues the casting strand into the downstream driving and straightening machine only made possible.
- commissioning i.e. When casting on a continuous caster, it is not possible without auxiliary measures, as they were already mentioned at the beginning, to handle the leading end of the newly formed casting strand with its still molten core for further transport into the driving and straightening machine.
- the new casting strand must therefore be connected to a cold strand, with the help of which it can be moved further into the driving and straightening machine.
- this process should relate both to the measures required when casting, i.e. starting a continuous casting installation, and to the measures taken when changing the batch, for example when the Plant to be transferred from one casting alloy to another.
- This procedure has the disadvantage that the core of the beginning of the casting strand had to solidify in order to form a positive connection between the casting metal and the cold strand.
- the cold strand supports cooling at the beginning of the casting strand, but it takes a relatively long time after opening the slide lock until the casting strand can be fed to the straightening machine. This is a considerable disadvantage when the slide closure of the intermediate container is open.
- a sand-shaped slide filling compound is often arranged during continuous casting over the closed slide closure of the intermediate container, which is intended to prevent the molten metal from being introduced into the slide gap.
- this slide filling compound first emerges from the outflow opening of the intermediate container and enters the casting mold.
- this sand which has reached the end of the cold strand is whirled up and often contaminates a considerable initial section of the casting strand, which must therefore be discarded.
- the transition from one casting alloy to another casting alloy during the operation of the continuous casting installation can be carried out continuously in that the intermediate container is charged with the new alloy before the previous filling has been completely used up. Although this does not lead to an interruption in production, it does lead to an undesirable transition section in the casting line which has to be discarded and is difficult to identify for this purpose. It is therefore preferred to empty the intermediate container before loading with the new alloy. However, this leads to an interruption in the production flow. According to the known procedure, an auxiliary cold strand had to be used again, which led to considerable losses in production time.
- the invention has for its object to propose a method and an arrangement for connecting a new casting strand in a continuous casting plant, which are primarily aimed at accelerating the tying process, but should also offer the possibility in special embodiments, on the one hand, the adverse influences possibly to minimize slider filling mass used and / or to simplify and accelerate the transition significantly when changing batches.
- This object is achieved according to the invention in a method of the type mentioned at the outset in that a hollow connecting sleeve which can be fastened to the cold strand end and is open at the top and at least largely closed at its lower end is used as the connecting means between the cold strand and the casting strand, the wall cross-sectional shape of which is similar to the cross-sectional contour of the mold cavity is, and the mold outlet essentially by means of this connecting sleeve is closed.
- the arrangement according to the invention is characterized in a corresponding manner.
- the thickness of the sleeve jacket is to be dimensioned such that the molten casting metal does not completely melt the sleeve jacket, but conversely the sleeve jacket has a cooling effect, and this is also the case by melting heat consumption during the partial melting of the connecting sleeve, which thus represents the first section of the strand shell being formed.
- additional shot parts can be arranged in the connecting sleeve, which also preferably have the composition of the casting metal.
- the connecting sleeve is easily attached to the cold strand end in that the cold strand itself or an extension pin connected to it by a Corresponding opening in the bottom of the connecting sleeve is inserted into the interior thereof and fixed there with a cross bolt which extends through a cross hole in the end of the cold strand or its extension pin.
- a cross hole is the only means that must be provided for connection to the sleeve. For fastening it is sufficient if the cross bolt is so long that its protruding ends are supported on the bottom of the connecting sleeve.
- the connecting sleeve When using this type of connection, the connecting sleeve must of course first be pushed onto the cold strand so far that the bolt can be pushed in and then pushed back until the bolt ends lie against their bottom. It is more appropriate to use a cross bolt, which is mounted in opposite bores of the sleeve wall. On the one hand, with such a design, the sleeve can be brought into its correct position immediately, on the other hand, the cross bolt is accessible from the outside in this way, so that it can be knocked out from the outside if the cold strand has fulfilled its task.
- the connecting sleeve may be expedient to connect the connecting sleeve to the cold strand in such a position that its end extends into the interior thereof over a not inconsiderable region of the sleeve length.
- the cold strand end itself also primarily contributes to the cooling of the first casting metal entering the sleeve. If, on the other hand, the cold strand end or its extension has a smaller diameter than the inside diameter of the sleeve, an annular space is hereby formed below the upper edge of the cold strand end, into which the pusher sand can first enter from the intermediate container.
- the connecting sleeve has a clear cross section which is at least the same size and design as the cross section of the mold outlet.
- the connecting sleeve with the cold strand end stored in it and any scrap filling which may be present is placed with its upper edge surrounding the mold outlet against the underside of the mold and held in this position. This simultaneously completes the mold exit. Since the connecting sleeve in this embodiment has a relatively large diameter, the end of the cold strand need not be provided with an extension pin here, but can be guided directly into the connecting sleeve through a corresponding opening in the bottom thereof.
- the cross section of the auxiliary cold strand used does not matter in the variant of the arrangement according to the invention described here, since the sealing is achieved by the upper edge of the connecting sleeve.
- the cold strand only has to be suitable for being able to be fed to the driving and straightening machine together with the casting strand.
- the cross bolt is supported by the cold strand end in the wall of the connecting sleeve
- the bottom of the connecting sleeve does not necessarily have to be fastened to it. It can in turn be attached to the cold strand.
- a base can be provided which has a certain gap distance from the lower edge of the sleeve shell and whose diameter is larger than that of the sleeve shell, so that the base protrudes in an annular manner above it.
- the connecting sleeve has a cross section which allows the sleeve to be inserted into the interior of the mold cavity.
- a cross section which allows the sleeve to be inserted into the interior of the mold cavity.
- the cold strand expediently has a cross section which roughly corresponds to the mold cavity or the casting strand, or is somewhat smaller.
- the cold strand end is provided with an extension pin which projects into the interior of the connecting sleeve.
- the extension pin can in turn be fixed in an axial bore in the cold strand end by a securing bolt.
- the intermediate plate is used for the lower sealing of the annular space surrounding the connecting sleeve.
- the intermediate plate is preferably designed as an insulating plate with a certain flexibility, which can consist of various suitable materials.
- the protruding edge of the insulation board can be additionally covered with shot parts to cool molten metal entering the gap outside the connecting sleeve.
- the molten metal not only gets into the interior of the connecting sleeve during casting, but, as already mentioned, also into the gap between the connecting sleeve and the mold wall.
- the melt penetrating there is cooled from two sides, namely on the one hand by the cooled mold wall and on the other hand by the wall material of the connecting sleeve.
- This wall material further reduces the heat flow from the melt inside the connecting sleeve to the cooled one Mold wall out, so that this arrangement forms a strand shell approach very quickly, which allows direct feeding of the arrangement to the driving and straightening machine.
- the entire arrangement of cold strand and connecting sleeve can be inserted into the continuous casting mold from the bottom, but in practice it has proven to be expedient to first pass the cold strand moving from below through the continuous casting mold until it protrudes from the inlet opening, then place the intermediate plate and the connecting sleeve on the cold strand end, connect the arrangement by means of the cross bolt and then move it back down into the interior of the mold cavity. It goes without saying that any dip tube possibly used in the continuous caster must first be removed from the mold inlet in order to bring it back into position after the connecting arrangement has been moved downwards.
- the arrangement variant described so far is also particularly suitable for connecting the new casting strand when changing batches.
- the casting strand must be stopped when the intermediate container becomes empty, so that its trailing end still remains in the continuous casting mold.
- An extension pin or a prepared arrangement of connecting sleeve, intermediate plate and extension pin with the extension pin is then inserted directly into the end of the casting strand with a still molten core.
- the end of the strand is fixed around the extension pin, so that it is integrated into the end of the strand.
- the arrangement according to the invention can then, as described above, for restarting the system and connecting the new casting strand Function. In this way, a very fast batch change is achieved.
- the trailing end of the preceding casting strand is also referred to as a cold strand in this procedure, even if it is not a cold strand used only in an auxiliary manner and does not yet need to have completely changed to the solidified state.
- FIG. 1 The partial representation of a continuous casting installation in FIG. 1 shows in its basic structure a pan 1, an intermediate container or tundish 2 and a continuous casting mold 3.
- the intermediate container 2 is in its Bottom with an outflow opening 4 with slide closure 5 for the liquid metal.
- slide closure 5 a plug closure or a slide and plug closure or another closure means can also be used.
- the plant is primarily used to produce cast steel.
- the continuous casting mold 3 has a mold inlet 6, a mold outlet 7 and a mold cavity 8.
- the continuous casting mold 3, shown only in the detail, is surrounded by a coolant 9 around the mold cavity 8.
- a slide filling compound 10 essentially a certain sand mixture, is arranged which, when the slide 5 is closed, is to prevent the metal melt 11 located in the intermediate container 2 from entering the slide mechanism and moving it.
- FIGS. 2 and 3 A first embodiment of an arrangement according to the invention, which can be in the position of circle A in FIG. 1, is shown in detail in FIGS. 2 and 3.
- a connecting sleeve l4 which consists of a sleeve jacket l5 and a sleeve base l6.
- the sleeve jacket l5 has a clear cross section which corresponds to that of the mold outlet 7, and the connecting sleeve l4 is arranged congruently with the mold outlet 7 under the mold 3.
- the socket bottom l6 has a bottom opening l7, through which the cold strand l2 is inserted with its end l8 from below into the interior of the connecting sleeve l4.
- a cross bolt 20 is arranged in a transverse bore l9 of the cold strand end l8, the projecting ends of which abut against the socket base l6 and through which the cold strand end l8 is prevented from leaving the connecting sleeve l4.
- the bottom opening l7 in the socket bottom l6 has a somewhat larger cross section than the cold strand end l8, so that an annular gap 2l remains, which, as will be described further below, serves as a sand outlet opening.
- the sleeve jacket l5 can be provided with fastening means which allow the fixed and sealing positioning of the connecting sleeve l4 below the continuous casting mold 3. Suitable fasteners are available in the prior art. Only grooves 22 are indicated in the sleeve jacket 15, into which fastening hooks or clips (not shown) can engage. Some shot parts 23 are arranged inside the connecting sleeve 14.
- the free-flowing slide filling compound 10 first reaches the connecting sleeve 14 and within it between the shot parts 23 the bottom of the connecting sleeve 14, from where at least the major part of the sand can exit the connecting sleeve downward through the sand outlet opening 2l.
- the amount of sand remaining within the connecting sleeve and largely covered by the shot parts 23 is so small that it is not directly reached by the subsequent molten metal when it hits the connecting sleeve, which prevents contamination of the metal by the filler sand.
- the tight contact of the connecting sleeve l4 on the underside l3 of the casting mold 3 prevents the metal melt from escaping from the mold and the connecting sleeve.
- the first molten metal entering the connecting sleeve l4 is cooled by the sleeve wall l5 and the shot parts 23 as well as the cold strand end l8 itself, the attempted melting of which consumes heat of fusion, so that, primarily including the sleeve shell, a strand shell is formed which includes a force-fit connection Connection between the sleeve and the casting strand leads, so that only a little later the cold strand l2 can be fed to the straightening machine with the connecting sleeve l4 and the casting strand connected to it, whereby the continuous casting process is started.
- the casting mold 3 has a circular cross section in the exemplary embodiment.
- the mold can have a wide variety of cross-sectional configurations depending on the product to be manufactured, and that the arrangement according to the invention can be adapted to each of these cross-sectional configurations by the sleeve jacket l5 having a corresponding cross-section, or else a cross section that is slightly larger than the cross section of the mold outlet.
- the one for the Arrangement shown used auxiliary strand has a much smaller cross section than the casting strand, which is even rectangular here in the example. However, this is not essential. The only requirement is that the auxiliary cold strand used can be fed to the straightening machine.
- FIGS. 4 and 5 differs from that according to FIGS. 2 and 3 in some features which are to be described below, for the rest parts which correspond to those of FIGS. 2 and 3 are the same Reference numerals.
- the cold strand end l8 projects further into the connecting sleeve l4 than in the arrangement according to FIG. 2.
- the cold strand end l8 is held by an elongated cross bolt 24, the ends of which extend a little above the socket bottom in opposite bores 25 is stored in the sleeve jacket l5.
- a deepened annular space 26 is created around it below the upper edge of the cold strand end l8 in the connecting sleeve l4. This annular space is partially filled with shot parts 23 and covered with a metal grid 26 above the shot parts.
- the slide filling compound 10 emerging from the intermediate container when the continuous casting system is cast on passes through the metal grid 26 between the shot parts 23 in the annular space 26 and is thus removed from the direct impact by the subsequent metal melt.
- a sand outlet opening is not absolutely necessary in this embodiment, but can also be provided. Shot parts and metal grids, which preferably have the same composition as the cast metal, contribute to cooling the molten metal in the lower area of the connecting sleeve at. Otherwise, the connection process of the new casting strand takes place as already described in connection with FIGS. 2 and 3.
- the sleeve base l6 may be expedient to arrange the sleeve base l6 at a certain gap distance from the sleeve jacket l5. Small amounts of molten metal that may escape through this gap are stopped by the asbestos cord ring 27 resting on the socket base 16.
- the sleeve base is larger than the outer cross section of the sleeve jacket. In addition, it is square, in contrast to the sleeve jacket. This shape can be useful for manufacturing reasons.
- FIGS. 6 and 7 A fundamentally different embodiment of the arrangement according to the invention is shown in FIGS. 6 and 7.
- the connecting sleeve l4 used here consists solely of the sleeve jacket l5, which has a somewhat smaller cross section than the mold cavity 8, so that the connecting sleeve l4 can be inserted into the interior of the mold cavity 8 while leaving a gap 28 between the sleeve jacket l5 and the mold inner wall.
- 6 shows the connecting sleeve 14 arranged in the interior of the mold cavity 8.
- an extension pin 29 is provided for connecting the end of the cold strand l2 to the connecting sleeve l4, the lower end of which extends in an axial recess 30 at the end of the Cold strand l2 rests and is anchored there by means of a securing bolt 3l which extends through aligned bores 32 in the extension pin and in the cold strand.
- the extension pin 29, as described for the cold-strand end 18 in connection with FIG. 4, is fastened within the connecting sleeve 14.
- an intermediate plate 33 made of an insulating material is arranged between the cold strand end 18 and the connecting sleeve 14, which protrudes like a collar over the outer circumference of the connecting sleeve 14 and extends as far as the inner mold wall.
- the collar-like protrusion of this intermediate plate is also covered with shot parts for cooling the melt reaching there.
- melt penetrating into the gap 28 is preferably cooled by the cooled mold wall as well as by the sleeve wall l5, whereby it solidifies and possibly partially melts with the sleeve wall l5, as a result of which the beginning of a strand shell is formed, which forms a non-positive connection with the connecting sleeve l4 comes in.
- the shot parts 34 on the intermediate plate 33 outside the connecting sleeve 14 contribute to the solidification of the melt in the lower region of the gap space 28, as a result of which the melt is prevented from destroying the intermediate plate and from premature escape from the mold cavity. After approximately 10 seconds or less after the slide closure opening, the arrangement of cold strand and connecting sleeve with the connected new casting strand can be fed to the driving and straightening machine.
- the arrangement shown in FIG. 6 is expediently carried out by first moving the cold strand end 18 from below through the mold 3, above the mold while inserting the transverse bolts with the Provide sleeve assembly and then the sleeve assembly is moved down into the interior of the mold. Since the connecting sleeve and the cold strand end are connected to one another so that they cannot move, the arrangement can be held in the position shown for as long as required by holding the cold strand 12.
- the arrangement described last can also advantageously be used for the rapid processing of a batch change, for example by inserting the extension pin 29 into the still molten core of the ending casting strand, whereupon after it is anchored by cooling the casting strand end from the completed casting process, the arrangement, as described above, can be provided for connecting the new casting strand.
