Definitions
- the invention relates to a slide closure for a metallurgical casting vessel, in particular ladle, with a slide plate displaceably mounted between a top plate and a spout plate.
- a slide closure is well known. Reference is made in this regard only by way of example to DE-B-26 52 593 or DE-A-36 16 115.
- DE-B-26 52 593 or DE-A-36 16 115 it is not possible to prevent ambient air from being sucked into the pouring channel during pouring via the slide closure, in particular between the top plate and the slide plate, and mixed with the molten metal. The result is uncontrolled metallurgical reactions that can seriously affect the quality of the final product.
- the present invention is therefore an object of the invention to provide a slide closure available, compared to the prior art considerably is built simpler, and still safely avoided that ambient air is sucked into the spout and the molten metal is added. This object is achieved by the characterizing features of claim 1, wherein preferred structural details and embodiments are described in the dependent claims.
- An essential aspect of the present invention is therefore that all plates of the slide closure, in the case of a three-plate slide, therefore, all three plates are arranged inside a slide housing which can be revealed if required, and that the slide housing can be closed to the outside in a substantially gas-tight manner.
- all plates of the slide closure in the case of a three-plate slide, therefore, all three plates are arranged inside a slide housing which can be revealed if required, and that the slide housing can be closed to the outside in a substantially gas-tight manner.
- the slide plate has at least one passage opening whose inner diameter preferably corresponds to the inner diameter of the corresponding passage openings of the head and spout plate. In principle, it is also conceivable that the inner diameter of the slide plate deviates from the inner diameters of the head and / or discharge plate.
- a second passage opening in the slide plate is conceivable, whose diameter is smaller than the aforementioned diameter, to a defined reduced spout of molten metal from the casting vessel, e.g. a ladle, to ensure.
- the slide plate would then in this case not only one, but two spaced-apart open positions.
- Argon is preferably used as the inert gas. It is particularly advantageous if the pressure, namely either the negative pressure or alternatively the inert gas overpressure, is adjustable within the valve housing, in particular is adjustable, preferably as a function of the slide plate position between "completely open” and “completely closed". For example, if the inert gas pressure in the valve body were set too high, inert gas could pass excessively into the molten metal between the plates of the valve and be entrained with it into a distributor trough. There is then the danger that inert gas bubbles rise through the slag and break up the slag layer or corresponding melt cover. Thus, the melt comes back directly in contact with ambient air, which leads to potentially adverse chemical reactions.
- the pressure namely either the negative pressure or alternatively the inert gas overpressure
- the pressure in the slide housing may be either underpressure or overpressure, depending on the slide plate position.
- full open position of the slide plate between this on the one hand and the head and / or spout plate on the other hand less ambient air or inert gas sucked than in half-open position.
- half-open or partial open position arises at the bottom of the protruding into the spout opening portion of the slide plate high negative pressure. Accordingly, more “inert gas” is “consumed”. This increased “inert gas consumption” can be compensated for by correspondingly increased inert gas supply into the valve housing.
- this negative pressure in the slide housing should be reduced accordingly to avoid that on the underside of the protruding into the spout part of the slide plate too high a negative pressure is produced, which is harmful could affect the metal flow.
- the side of the slide housing facing the pouring vessel comprises a mounting plate for the top plate, or this side is defined by the mounting plate, between this side or mounting plate and casting vessel preferably a circumferential seal, in particular sealing cord is arranged.
- the slide plate is preferably held within a slide plate frame and together with this from a closed to an open position and vice versa.
- the slider housing by the mounting plate comprehensive side on the one hand and a pivotally mounted about a first axis mounted box-like frame on the other hand, wherein on the opposite side of the mounting plate, the spout plate is mounted.
- a circumferential seal in particular sealing cord arranged. This seal is therefore assigned to the same freely open at the opening of the slide housing sides.
- the valve housing is closed then the corresponding seal against the external environment is effective.
- the slide plate frame together with slide plate on the box-like frame of the slide housing to a second, in particular approximately parallel to the first axis extending axis
- connection part is designed for coupling to a complementary connection element of the slide plate drive, the latter protrudes into the interior of the slide housing to be automatically locked there when closing the slide housing with the connection part of the slide plate frame. So that is the slide plate with the slide valve housing always in operative connection with the slide plate drive.
- the slide plate frame is either manually or automatically locked to a separate swing frame when opening the slide plate and simultaneous decoupling of the slide plate frame including slide plate from the slide plate drive, or vice versa when closing the slide housing unlocked. This ensures that when the valve body is closed, the slide plate frame together with the slide plate is freely displaceable back and forth, while with the slide valve housing open, the slide plate frame including slide plate remains securely held on the slide housing, via the separate swing frame.
- the slide plate frame locking mechanism includes a locking pin slidably mounted on the swing frame and cooperating with a corresponding pin receiver in the slide plate frame.
- a locking pin slidably mounted on the swing frame and cooperating with a corresponding pin receiver in the slide plate frame.
- the locking pin engages in the pin receptacle. Conversely, it behaves when unlocking the slide plate frame including slide plate.
