Definitions
- the invention relates to a refractory ceramic slide plate and an associated Schieberpiattenset.
- a single slide plate or a so-called slide plate set are components of a slide closure (slide system) for controlling the outflow and Ausfii speed of a molten metal from a metallurgical vessel, such as a ladle or a Swissbcpiancr (English: tundish).
- Slide systems of the type mentioned include so-called linear slide and rotary valve. They can include two or more plates. At least one of the plates is movable (in the case of a linear slide: linearly movable, in the case of a rotary slide valve: rotationally movable), Each plate has two parallel main surfaces and at least one opening extending between the main surfaces, that is perpendicular to the main surfaces.
- corresponding openings of the plates can be offset, partially overlapping or aligned with each other to adjust the mass and velocity of the melt passed therethrough or to interrupt the melt flow.
- All panels are made of a refractory ceramic material capable of withstanding the high temperatures of the molten metal (for example 1500 ° C). In particular, when opening and closing the slide closure, there are strong corrosion phenomena of the refractory material.
- the EP 0 373 287 A2 describes a slide plate having a plurality of flow openings, so that the slide plate can be used even if the first flow opening is worn by the second flow opening is used to control the slide closure.
- the invention has for its object to offer a slide plate, which allows an optimized flow of the passed molten metal.
- the shortest distance between two circular openings is the distance along a straight line passing through the centers of the openings. Often, this straight line will define the direction of displacement of the slide plate in a linear slide.
- displacement direction of the slide plate is basically a straight line in a linear slide, with a rotary slide the direction of displacement runs along a circular arc.
- a first partial flow flows through the spout opening of the further plate of the spool closure and then through a portion of the first spout opening, while a second partial flow also flows through the spout opening of the further (usually stationary) plate of the spool closure and then through at least a portion of the second spout opening of the spool plate ,
- the essential feature of the slide plate is thus to enable optimized control with less wear via at least one second pouring hole (a second Ausgussä réelle), which can be switched fluidically at least partially parallel to the first pouring hole.
- the vast majority of the pouring stream can be poured off via a small pouring spout, which is brought completely under the spout opening of the associated (further) plate of the spool closure.
- the larger spout opening can serve together with the other opening for fine control of the flow rate of the molten metal, depending after, to what extent it is additionally brought into fluid communication with the spout opening of the further plate (s).
- a reduced amount of melt that flows through a restricted spout opening in the constellation described above causes only less erosion / corrosion.
- the risk is reduced that air is sucked in the region of the slide closure, provided that the casting takes place largely on the smaller spout opening and only sections of the larger spout opening are also in fluid communication with the spout opening of the associated plate.
- This is due to the fact that the melt flow through the smaller spout opening then takes place centrally (for example coaxially) with respect to the spout openings of the further plates.
- the spout opening of the slide plate always has a clearance from the boundary wall of the spout opening of the associated (usually solid) plate. This too is evident from the following description of the figures.
- the shortest distance from two adjacent spout openings is 0.01 to 0.5 times the largest chord of the two spout openings.
- This distance may, in one embodiment, be limited to a lower limit of 0.05 and / or an upper limit of 0.35.
- An alternative lower limit is 0.1, another possible upper limit is 0.25 or 0.30.
- An embodiment of the invention provides that in the region of at least one main surface, the sum of the cross-sectional area of the small-cross-sectional area spout and x times the cross-sectional area of the large cross-sectional area spout is greater than or equal to the cross-sectional area of the large cross-section spout x has a value ⁇ 0.4 and ⁇ 0.4 and ⁇ 0.95, in particular a value ⁇ 0.9, ⁇ 0.8 or ⁇ 0.7 or ⁇ 0.6 with lower limit values at ⁇ 0.45, ⁇ 0.50 or ⁇ 0.55.
- QS20 is the cross-sectional area of the small cross-sectional area spout and QS10 is the cross-sectional area of the large cross-sectional area spout.
- suitable lower limits for x are 0.10; 0.20 or 0.25 and appropriate upper limits for x at 0.90; 0.80 or 0.70, where QS defines the respective circle diameter.
- ⁇ QS ⁇ 20 detects the cross-sections of the spout openings that can be brought into fluid communication with a spout opening of an adjacent plate simultaneously with the spout with large cross-section (QS10), where ⁇ QS20 does not contain QS10.
- the spout opening (s) may have a circular cross section, although this is preferred.
- the spout openings may have any geometric cross section, for example rectangular or polygonal,
- the cross-sectional area of the spout openings between the main surfaces is constant, so that results in a circular cross-section, a cylindrical spout opening.
- the invention is not limited to such embodiments, it also includes spout openings, which for example have a funnel-shaped profile.
- the centers of the spout openings along a main surface may lie on a common straight line in the case of a linear spool closure and on a common circular line in the case of a rotary spool closure. This information is not in the exact mathematical sense, but to understand technical, for example, taking into account production tolerances. You can also be arranged offset to the direction of displacement, as shown in the following embodiment.
- the invention also includes a complete slide plate set (a complete slide closure), which consists of at least one slide plate of the type mentioned above and at least one further plate, wherein corresponding plates are aligned in their functional position with their respective main surfaces flat against each other.
- the at least one further plate has at least one spout opening, the cross-sectional area and arrangement of which are selected such that it completely and / or partially covers one or more spout openings of the slide plate as a function of the position of the slide plate.
- slide plate like the further plate (s), can be designed according to the state of the art with respect to its respective material or its assembly (for example in a metal cassette).
- the value 50% can be extended to 60%, but smaller values ( ⁇ 45%, ⁇ 40%, ⁇ 30%) are preferred, so that as much melt as possible flows through the smaller opening.
- the centers of all spouts are preferably along corresponding major surfaces in a common plane that is perpendicular to the major surfaces. This applies to a linear slide gate valve.
- the centers of all the spouts are along corresponding major surfaces in a common cylinder surface, which is perpendicular to the main surfaces.
- FIG. 1 shows a slide plate S according to the invention, which has an upper main surface SO and a parallel extending lower main surface SU and in the plan view (above in FIG. 1 ) has approximately an oval shape.
- the larger spout opening S10 has a diameter SS10.
- the diameter of the smaller spout opening S20 is designated SS20.
- Both spout openings S10, S20 have a constant circular cross-section between the main surfaces SO, SU, wherein the associated central longitudinal axes are denoted by MS10, MS20.
- FIG. 2 shows the assignment of such a slide plate S in a 3-plate slide valve closure.
- the corresponding slide plate set comprises three plates, namely an upper, fixed plate PO and a lower, fixed plate PU. Between two or the bottom POU of the plate PO and the top PUO of the plate PU extends the slide plate S.
- the plates PO, PU each have a pouring opening PO10, PU10, each with a circular cross-section and the same dimensions to the spout opening S 10 of the slide plate S.
- the smaller spout opening S20 of the slide plate S is covered upwardly by the plate PO and bounded below by the plate PU.
- no molten metal flows out of the above-arranged melting vessel SG or the associated sleeve H into downstream aggregates through the spout opening S20, which are denoted here only schematically by A.
- FIG. 3 shows a position of the slide plate S, compared to the position according to FIG. 2 is shifted to the left, so that the smaller spout opening S20 is completely in the region of the spout opening PO10, but the larger spout opening S10 is still not completely removed from the covering area with the spout openings P010, PU10.
- M melt stream
- the partial flow M10 has approximately a speed G2 which is greater than G0.
- the flow profile is such that a region is formed in the middle in which the flow velocity G1 is greater than G2, wherein G2 is observed in the outer region of the melt stream M20. It goes without saying that the transitions between each. Speed information is not gradual, but continuous.
- the inventive assignment of the two spout openings of the slide plate S thus not only increases the controllability of Schieberplattensets (the slide closure), but also improves the quality of the passed metal melt in comparison with the prior art due to lower oxidation.
- FIG. 4 The state of the art is in FIG. 4 shown. All spout openings of all plates are identical. In a linear displacement of the slide plate S, although it comes to a throttling (reducing the flow rate) of the molten metal. In this way, however, at the same time the risk of undesired air infiltration in the transition region between adjacent plates is increased. In addition, it has been observed that in the region of the edge K of the slide plate S, a deflection of the flow and a greatly increased flow velocity of the molten metal are formed, causing high corrosion and erosion. This can be avoided with the design according to the invention.
- FIG. 5 shows another embodiment of a linear slide plate S.
- the diameter SS10 of the large flow passage S10 is 60 mm
- the diameter SS20 of the small flow passage S20 is 25 mm
- the shortest distance s1 between both spouts S10, S20 is 15 mm.
- the result for the spout opening S10 is a cross-sectional area of 2.827 mm 2 , for S20 a value of 491 mm 2.
- the opening PO10 of an adjacent plate is indicated.
- the value x for the above-mentioned formula is accordingly about 0.83.
- the direction of displacement is indicated by VV.
- the opening S20 is offset to the displacement direction VV (distance AB to the center of the opening S20).
- the diameter of the spout opening PO10 is also 60 mm.
- the distance S1 is 17 mm.
- the spout opening S20 of the slide plate S is correspondingly completely and the spout opening S10 of the slide plate S to about 21.9% of the Ausgussöfinung PU10 covered in the position shown.
- FIG. 7 is an embodiment similar FIG. 6 shown, wherein the spout openings, however, have no circular cross-section, but each having a square cross-section. It is readily apparent that in the illustrated allocation of the spouts PO10 of upper plate PO and slide plate S, the degree of coverage with the smaller spout opening S20 is 100% and the Kochdcckungsgrad with the larger spout opening S10 50%.
- FIG. 8 Finally, a representation is similar FIG. 5 However, for a rotary seal closure, wherein the circular displacement is shown with VV.
- the slide plate S may consist of a carbon-bonded material.
