Definitions
- the invention relates to a closure plate for a sliding closure on the spout of a container containing molten metal, with a refractory plate, a sheet metal jacket surrounding it and with a centering means which is designed such that the closure plate can be inserted loosely into a metal frame of the sliding closure and is centered therein at least in the direction of displacement ; as well as a slide lock for it.
- the metal housing surrounding the plate at the bottom and laterally has one or a plurality of projections, which protrude into corresponding recesses. - 2 -
- the present invention was based on the object of creating a closure plate of the type mentioned at the outset, which can be produced simply and inexpensively with precise centering in a metal frame.
- the dimensions of this closure plate should be such that the space required when stacking such plates is kept to a minimum and the risk of damage to this centering means can be excluded as far as possible.
- the centering means is preferably formed by two stop surfaces arranged at a defined distance from one another, each of which approximately at least partially rises perpendicularly to the plate support formed by the sheet metal jacket and approximately has a thickness like the sheet metal jacket thickness, these stop faces being such are arranged so that they lie in the inserted and centered state of the plate on appropriately designed stop surfaces on the metal frame.
- this closure plate can be manufactured in a simple manner in terms of production, but nevertheless it ensures such centering in a metal frame of the sliding closure that it can be operated in an extremely reliable manner. Exemplary embodiments and further advantages of the invention are explained in more detail with reference to the drawing. It shows:
- FIG. 1 shows a longitudinal section of a partially shown sliding closure with closure plates according to the invention
- FIG. 3 shows the closure plate in a plan view along the line III-III according to FIG. 1,
- FIG. 3A shows a cross section of the closure plate along the line A-A according to FIG.
- FIG. 10 shows a top view of a closure plate variant
- FIG. 10A shows the closure plate according to FIG. 10 in longitudinal section.
- Fig. L shows a section of a sliding closure 10 on the spout of a metal-containing container, of which only the outer steel jacket 13 and a refractory perforated brick 17 are indicated.
- This container is preferably a pan that can be filled with molten steel for a continuous caster.
- a refractory sleeve 1 1 forms the pouring opening 12 from this container.
- the lower closure plate 20 serves to open or close the closure 10 and for this purpose it is held in a longitudinally movable slide unit designed as a metal frame 15, in which a refractory pouring sleeve 16 adjoining the plate 20 is also mounted.
- This slide closure 10 is designed in a conventional manner and therefore no longer shown in detail below.
- the closure plates 20 each have a prefabricated, usually deep-drawn, stamped sheet metal jacket 21 and a plate 22, which is made of a refractory ceramic material and is mortared in this.
- the mortar 28 is brushed into the sheet metal jacket 21 in the plastic state and after inserting the refractory plate, it dries and holds the latter in place.
- This plate 20, which is manufactured separately as a unit, is then loosely inserted as a whole into the metal frame 14, 15 and is held therein at least in the direction of displacement by means of a centering means.
- the closing plate 20 is assigned a centering means, which according to the invention is preferably formed by two stop surfaces 23, 24 arranged at a defined distance from one another.
- These stop surfaces 23, 24 rise approximately perpendicular to the plate support 26 formed by the sheet metal jacket 21 according to FIG. 2, and they are each approximately provided with a height such as the sheet metal jacket thickness 21 '.
- these stop surfaces 23, 24 rest against correspondingly designed stop surfaces 18 ', 19' on the metal frame 14, 15, so that the plate 20 is held therein loosely and with almost no play in the direction of displacement.
- the metal frame 14, 15 each has a protruding nose 18, 19, each with a stop surface 18 ', 19'.
- These cooperating stop surfaces 18 ', 19' and 23, 24 are each formed with respect to the plate support surface 26 as straight vertical surfaces; they could each be slightly cambered or beveled to make it easier to insert the plate into the frame. - 5th
- the sheet metal jacket 21 is provided with a separating point to form the respective stop surface 23, 24 and a rib 21 ′′ bent inwards at this point.
- the end edge produced in the sheet metal jacket 21 with this separating point accordingly forms the corresponding stop surface 23, 24, which is released by the rib 21 ".
- the rib 21 " is bent inwards in such a way that its lower edge at the end separation point adjoins the upper of the sheet metal jacket forming the continuation without any space. This offers the advantage that there is no mortar 28 between the rib and the sheet metal jacket continuation can penetrate and this stop surface 24 is therefore not contaminated.
- This rib 21 "with the corresponding separating point can be produced in one operation due to the sheet metal jacket 21 produced by deep drawing.
- the tool shape receiving the sheet metal jacket and the stamp are designed such that the sheet metal jacket is deep-drawn and trough-shaped on the die mold while it is pressed into the tool shape
- the stop surface 23, 24 produced with this deep-drawing process can be provided with a precise dimensional tolerance in the tenths of a millimeter range without special finishing, so that such a closing plate can be easily equipped with the centering means described above.
- these two rectilinear elongated stop surfaces 23, 24 extend on the back of the plate at right angles to the longitudinal axis 21A of the plate. In this case, they are arranged at the same distance from the pouring opening 12 and are provided with a length of approximately half the plate width, which are dimensioned in such a way that, in the operating state, they correspond to the respective - 6 -
- ge stop surface 23, 24 of the sheet metal jacket 21 arising compressive forces are absorbed without deformation.
- This arrangement means that one stop surface 23 is arranged on one side and the other stop surface 24 on the other side of the pouring opening 12 and this results in a distance of more than half the length of the plate, and that the stop surfaces 23, 24 follow the plates are directed outward, there is a further advantage within the scope of the invention when mounting the plate 20 in the respective metal frame 14, 15.
- the plates 20 Before being inserted, the plates 20 are in the cold state at room temperature, but the metal frames 14, 15 of the sliding closure 10 on the pan generally have a temperature of approximately 200 ° to 300 ° Celsius from the previous use.
- 3A shows a partial cross section of the centering of the plate 20 in the metallic frame 15 transversely to the longitudinal axis 21A of the plate. It can be seen from this that the rib 21 "is formed at a uniform distance from the plate support 26 and the refractory plate 22 preferably abuts on the inside of this rib 21". This enables a parallel alignment a defined distance between the refractory plate 22 and the support 26.
- the nose 19 of the metal frame and the rib 21 "are each provided with such a length that the rib 21" with its ends 27 on both sides with little play to the outside 28 'of the Nose 19 is arranged in the inserted state of the plate, so that the plate 20 is also somewhat centered transversely to the longitudinal axis 21A of the plate.
- the closure plates of the exemplary embodiments explained below in accordance with FIGS. 4 to 10 are constructed in a manner similar to the plate 20 already described in detail above. Therefore, only the differences and their specific training are explained below.
- the refractory plates 22 are preferably each mortared in the sheet metal jacket.
- FIG. 4 shows a closure plate 40 with a centering means according to the invention, in which the two stop surfaces 43, 44 are formed side by side by a strip-shaped rib 41 ′ of the sheet metal jacket 41 that is bent inwards.
- This rib 41 ' is laterally delimited by two separating points from the sheet metal jacket 41 and is arranged on one side of the plate mounting surface.
- the metal frame 15 in turn has a correspondingly shaped rectangular nose 36, on each side of which there is a stop surface which corresponds to that of the plate 40.
- the closure plate 50 according to FIG. 5 differs from the plate 20, which is shown in detail in FIG. 2 and FIG. 3, only in that no separation points are provided for the ribs 51 "to form the stop surfaces 53, 54, but that they are pressed into the sheet metal jacket 51 in a groove-like manner.
- 6 shows a closure plate 60 with a sheet metal jacket 61, in which two ribs 61 "are provided analogously to those in accordance with FIG. 2 to form stop surfaces 63, 64, but with the difference that both ribs 61" on the longer side of the Contact surface are arranged parallel to each other.
- FIG. 7 shows a closure plate 70, in which the centering means according to the invention are in turn designed as ribs 71 ′′ provided in the sheet metal jacket 71, as shown in FIG. 3, but these ribs 71 ′′ protrude from the plate 22.
- the stop faces 73, 74 are accordingly formed by the end faces on the ribs 71 ′′, however the stop faces of the metal frame are produced by longitudinal grooves 79 formed therein.
- FIG. 8 shows a closure plate 80 provided with stop surfaces 83, 84, which differs from that according to FIG. 7 only in that its refractory plate 82 is provided with tooth-shaped reinforcements 82 ′ which extend into the recesses in the sheet metal jacket formed by the bending of the ribs 81 protrude.
- the abutment surfaces 93, 94 are formed by a sheet-metal strip 95 which is fastened to the underside of the sheet metal jacket 91, in particular spot-welded.
- This sheet metal strip 95 is preferably rectangular and the end edges serving as stop surfaces 93, 94 on it are arranged at right angles to the longitudinal axis of the plate 90.
- FIGS. 10 and 10A show a further embodiment of a closure plate 100 in which the stop surfaces 103, 104 are bent downward rip pen 101 ', 103'.
- These stop surfaces 103, 104 are characterized by their circular design, the circle formed by them being arranged concentrically to the pouring opening of the plate, thereby ensuring that this opening is exactly centered in the metal frame of the sliding closure and thus the openings of the two closure plates are concentric with one another are arranged.
- these stop surfaces could also be provided with a different shape instead of straight or circular.
- stop surfaces provided on the underside of the plate are advantageously formed directly on the sheet metal jacket for the purpose of simple manufacture. In principle, however, they could also be provided directly on the refractory plate 22, in particular if the refractory plate 22 would lie directly on the metal frame 15 in a manner known per se and in between there would be no sheet metal jacket, but only a bandage ring encompassing the plate on the side. The stop surfaces would then be contained directly in the refractory plate 22, in particular through one or two recesses on the underside of the refractory plate 22.
