Definitions
- the invention relates to a baffle for a casting container for casting metallic melts, with a wall surrounding a baffle, which defines in connection with the baffle an open volume within the baffle into which metallic melt is poured, with at least one arranged on the baffle pot connection for connection to at least one gas-conveying line, wherein the connection is gas-conductively connected to at least one opening, from which gas can be diverted. Furthermore, the invention relates to a device for casting a metallic melt and a method for casting a metallic melt.
- Baffles are arranged in casting containers or also distributors, in particular in a so-called tundish, which is filled with metallic melt, preferably with a molten steel, and the molten steel is distributed in tundish, in particular two pouring, which in each case with a mold for producing a cast product in combination stand.
- Such embodiments are preferably part of a continuous casting plant.
- the baffle has the task on the one hand to protect the lining of the tundish by the incoming pouring stream and on the other to prevent a short-circuit flow between entering (coming from the shadow tube) and exiting (flowing into the immersion nozzle) pouring stream, see for example DE 10 2004 011 883 B4 ,
- WO 2000/050190 A1 In order to improve the degree of purity in cast products, it is proposed in WO 2000/050190 A1 to provide a baffle pot acted upon with gas.
- the baffle is placed below a shadow tube from which the pouring stream enters a tundish, the latter having porous side walls through which a gas can be passed.
- the gas emerging from the porous sidewalls floods in the form of gas bubbles an area outside the impingement area of the incoming pouring stream at the impact pot and forms a kind of "gas bubble curtain" through which the deflected and / or deflected melt passes after the impingement of the pouring stream
- Too large and / or undefined gas bubble diameter are not suitable to completely absorb oxidic accompanying elements.
- the object of the invention to provide a baffle pot, which is designed more effective compared to the prior art in terms of improving the degree of purity in casting products to be produced.
- the object according to the impact pot is achieved in that the at least one opening points in the direction of the open volume for the outflow of a gas.
- the inventors have surprisingly found that by flooding the open volume with gas bubbles or with a gas bubble swarm the pulse respectively the energy and the turbulence of the incoming pouring stream can be exploited advantageously and effectively.
- the interaction between the gas bubbles and the pouring stream may further reduce the diameter of the gas bubbles flowing out of the openings as a result of the shearing action.
- the high turbulences prevailing in the impact area can lead to a higher probability of collision between the gas bubbles and the oxidic accompanying elements or between the oxidic accompanying elements, which leads to a more frequent combination between gas bubbles and oxidic accompanying elements or between the oxidic accompanying elements to produce a cluster can, whereby the density is reduced by the combination of the gas bubble-Begleitelement- or gas bubble-accompanying element cluster structure, which in turn can lead to a faster rise to the melt surface and thus better deposition in the slag at the melt surface.
- the baffle pot at least one opening or several openings are provided in the baffle surface.
- the opening is preferably formed in the form of a nozzle, which is for example formed integrally with the baffle made of a refractory material or is integrated as an additional part during or after the production of the baffle pot in the opening.
- the nozzle shape has the advantage, compared to a porous structure, that defined gas bubble diameters can be generated.
- the openings may be distributed substantially deterministically in the baffle, for example structured but also arranged unstructured. Alternatively, the openings may be arranged only in the central region of the baffle or circumferentially around the central region of the baffle.
- the openings in the baffle surface By providing the openings in the baffle surface, the gas bubbles or the generated gas bubble swarm are directly opposite to the incoming pouring stream, whereby the diameter of the gas bubbles or gas bubble swirling out of the openings can be further reduced in the area of action.
- At least one opening is cumulatively or alternatively provided in the wall. Is / are the openings cumulatively provided, so the additional flooding of the open volume transverse to the outlet direction of the effluent from the openings in the baffle gas bubbles or Gasblasenschwarms and transverse to the incoming pouring stream to reduce the diameter of the gas bubbles and / or to increase the union of Contribute to gas bubble companion element or gas bubble companion element cluster structures.
- the impact pot can be round, oval or angular. Other geometries are conceivable and adaptable to the respective application.
- the baffle surface or the surfaces of the walls in the direction of open volume, in which openings may be provided, according to a further embodiment of the baffle pot must not be made smooth, but can to generate a higher shear between incoming pouring stream and gas bubbles grooves and / or raised structures of any Have geometry. This may additionally promote the generation of small gas bubble diameters.
- the second aspect of the invention relates to a device for casting a metallic melt to produce a cast product, comprising a casting vessel for receiving a metallic melt, which is connected to a shadow tube over which a casting container is filled with metallic melt, wherein a baffle in the casting container is arranged below the shade tube and is exposed to the incoming pouring stream, the casting container at least one pouring opening for filling a mold associated with the casting mold with metallic melt to produce a cast product, preferably the casting container two pouring openings for filling a respective mold with metallic melt to Producing each having a cast product, wherein the baffle corresponds to at least one of the aforementioned embodiments.
- the third aspect of the invention relates to a method for casting a metallic melt to produce a cast product, wherein a device according to one of the aforementioned embodiments is used.
- an inert gas is used as the gas.
- argon is used as the gas because it is unreactive and inexpensive to obtain. It would also be conceivable to use other gases, such as, for example, nitrogen, in order to allow a targeted reaction with the metallic melt, which improves the product during further processing and / or permits new material and / or application properties.
