The spout casing (1) projecting into the casting tube (3) and there being provided between the latter a casing-like seal (8) with a collar (9) lying on the face side of the casting tube (3') at the top. There is assigned to the spout casing (1) on the outside at least one sealing ring (11), which is positioned such that the latter can be pressed again the collar (9) of the seal (8) lying on the face side of the casting tube (3') at the top. With this sealing system is achieved a constructionally simple structure and perfect tightness between the spout casing (1) and the casting tube (3).
Description
- The invention relates to a sealing system according to the preamble of
Claim 1, and to a refractory spout casing. - This type of arrangement is used, for example, for the casting of steel by the continuous casting method. The spout forms the outlet of a slide gate of a metallurgical vessel here. The casting tube connected to said spout in an air-tight manner conveys the molten steel into a die suitable for the purpose.
- It is well known that the sealing system between the spout casing and the casting tube serves to prevent ambient air from being sucked into the molten steel through their connection seat when casting. For this purpose inert gas is supplied to the region of the connection seat, and the gas pressure of said inert gas counters the suction effect of the molten steel flowing through when casting. This type of sealing system is disclosed by
DE 40 24 520 A1 . A disadvantage of the latter is that the supply of the sealing system with inert gas is structurally complex and in addition is expensive, both due to the quantities of gas required and due to the gas pressure required. - The object underlying the invention is to avoid these disadvantages and to provide a sealing system of the type specified at the start that is characterised by a constructionally simple structure and perfect tightness of the system.
- This object is achieved according to the invention in that the spout casing has a sealing ring that can be pressed in an air-tight manner against the seal of the casting tube on the face side. Thus, without introducing any inert gas either, the sealing ring brings about air-tight blocking of the sealing seat, especially as the negative pressure that occurs during casting automatically supports the pressing of the sealing ring against the seal of the casting tube. In this way it is possible to dispense with the supply of inert gas to the sealing seat or, if this is provided, to largely reduce it. In both cases considerable financial advantages arise from this. The sealing system is structurally very simple and is reliable in operation to a high degree.
- In this sense it is particularly advantageous if a sheet metal ring preferably produced from sheet steel is used as a sealing ring, the radial width of which is matched to that of the seal of the casting tube.
- Furthermore, the invention makes provision such that the sealing ring is positioned at a defined height of the spout casing which is calculated such that it guarantees total coverage of the seat surfaces of the casting tube and the spout casing in the assembled state.
- It is advantageous for reasons relating to production and fitting if the seal of the casting tube is produced from fibrous ceramic material in the form of a conically moulded sealing casing which is provided with a face-side collar for enlarging the pressing surface of the sealing ring.
- The sealing system according to the invention can also be used in devices the casting tube of which is provided with an inert gas feed opening out into the region of its seal.
- A spout casing particularly suitable for the sealing system is characterised in that it is provided with a one- or multiple-part sheet metal jacket to which holders for the sealing ring are applied arranged distributed around the perimeter. Since it is in any case normal to use spout casings covered in sheet metal, the holders are preferably welded directly onto the existing sheet metal jacket in the form of sheet metal straps.
- According to the invention the sealing ring is fastened to the sheet metal straps with detachable connection means which can be screwed into the sheet metal straps or are driven into bore holes in the sheet metal straps as bolts or pins.
- In the following the invention will be described in more detail using an exemplary embodiment with reference to the drawings. These show as follows:
- Fig. 1
- a longitudinal section of a partially shown slide gate comprising a sealing system according to the invention with a spout casing and a casting tube;
- Fig. 2
- a detail A of the spout casing in a view in the direction of the arrow B according to
Fig. 2 ; - Fig. 3
- a partial longitudinal section of the spout casing according to
Fig. 1 ; - Fig. 4
- a top view of a sealing ring for the spout casing according to
Fig. 3 ; and - Fig. 5
- a section of the sealing ring according to
Fig. 4 . - The
slide gate 20 shown inFig. 1 on the spout of a metallurgical vessel (not detailed) which can be, for example, a ladle filled with molten steel, comprises ahousing 21 that can be fastened to the vessel and aslide unit 22 into which at least onerefractory closure plate centring elements 26. - By shifting this
slide unit 22 theseclosure plates flow openings 5 in the same opening takes place - as shown - or closing of theslide gate 20 in a conventional manner. In the latter are moreover arefractory casing 27 shown partially projecting into the vessel and adjoining beneath theclosure plate 24 in the slide unit is arefractory spout casing 1 which is held in theslide unit 22 by means of adetachable fastening element 25 which can be, for example, a bayonet ring. In principle however thespout casing 1 could also be connected to theclosure plate 24 as one unit. - Advantageously the
spout casing 1 is formed tapering downwards conically on the outside and has in the upper part a collar 1' which serves as a contact surface in the bayonet ring. Pressed tightly against thisspout casing 1 by means of an apparatus (not detailed) is arefractory casting tube 3 which is also called a ladle shroud and generally plunges into the molten steel of a distributor vessel located beneath the slide gate so that the molten steel poured in a controlled manner into the latter from the vessel is protected from the ambient air. Thiscasting tube 3 is provided with an upper end 4 extending conically on the inside, and like thespout casing 1, is provided with a through boring 5a or 5b. - The
spout casing 1 is covered by a one- or multiple-partsheet metal jacket 6 theconical part 7 of which is pressed against a casing-like seal 8 preferably produced from a fibrous ceramic material with acollar 9 lying on the face side of the casting tube 3' at the top. Thisseal 8 is inserted, accurately fitting, into thecasting tube 3. - According to the invention the sealing seat formed by the
sheet metal jacket 6 of thespout casing 1 and that formed by theseal 8 is additionally sealed with asealing ring 11. This sealingring 11 advantageously produced from sheet steel is positioned in aholder 12 of thesheet metal jacket 6 and is pressed against thecollar 9 of theseal 8 of the casting tube. It thus provides together with theseal 8 double sealing of the formed sealing seat. - The
holder 12 and the fastening means for thesealing ring 11 are illustrated inFig. 2 to Fig. 5 . Theholder 12 is formed by a number of, for example three,straps 14 made of sheet steel arranged distributed around the perimeter, which are welded onto thesheet metal jacket 6 on the inside. Thestraps 14 have receivingbore holes 15 for the fastening means of the sealing ring. - In addition, within the framework of the invention these
straps 14 are dimensioned such that they form together with thespout casing 1 an outside diameter D1 which has dimensions equal to or smaller than the inside diameter 25' of thebayonet ring 25 and so thespout casing 1 can be inserted into thebayonet ring 25. - In the exemplary embodiment described holding bolts or
pins 16 are provided as fastening means. These are welded into the sealingring 11 and passed into the receivingbore holes 15 of thestraps 14 so that they position the sealingring 11 in the fitting position suitable for even pressing. The pressing force is primarily applied by the pressed oncasting tube 3, but during casting it is increased according to the invention by a pressure difference P1 minus P2 then being produced between the pressure P1 of the surrounding area and pressure P2 in the interior of the passage opening 5b which supports the pressing of the sealingring 11 against theseal 8 of the casting tube when pouring off molten metal. - The interaction of the
seal 8 with thecollar 9 and thesealing ring 11 thus enables sealing of the sealing seat that automatically strengthens when casting. Ambient air and so oxygen is thus prevented from penetrating into the molten metal through the sealing seat and impairing the quality of the molten metal. In this way a reliably operating sealing system is produced that makes the otherwise required supply of inert gas in order to establish a counter-pressure neutralising the suction effect unnecessary. - The sealing system according to the invention is structurally simple, reliable and financially advantageous, in particular with regard to the otherwise high operating costs associated with the consumption of the expensive inert gas.
- Within the framework of the invention it is also possible, in order to fasten the
sealing ring 11 in theholders 14, to use instead of theholding pins 16 connection elements which can be screwed into thebore holes 15 of theholders 14. Both fastening possibilities make it possible to fit thesealing ring 11 in thespout casing 1 when the latter is already fitted in the metallurgical vessel or theslide gate 20 fastened to the latter. - The arrangement of the
holders 14 in thespout casing 1 defines the installation height of the sealing ring. In practice this is chosen such that it guarantees full coverage of its seat surfaces according to the dimensions of the spout casing and the casting tube. - The sealing system according to the invention can also be used in conventional devices with an inert gas supply. In this case the gas supply is restricted to a minimum or optionally it is totally stopped.
- Needless to say the invention could also be demonstrated by other configurations. Thus, for example, the sealing
ring 11 could be formed like a frame in order to increase stability. Instead of these straps 14 a ring or similar surrounding thespout casing 1 could also be provided. - The sealing
ring 11 could also only strike theholder 12 for the purpose of positioning, but not be fastened to the latter. - Those sealing system according to the invention could also be applied for other devices respective closure systems on the spout of metallurgical vessels, like for instance for a stopper rod, a tundish slide gate, a metering nozzle, a nozzle change system or the like. Thereby the casting tube could be used as a submerged nozzle, which would for instance be submergeable into the molten metal in a casting mould.
