Definitions
- the invention relates to a slide closure on the spout of a metal-containing vessel, with a slide housing, a base plate arranged therein in a stationary manner and a slide plate which can be pressed against it by means of spring elements and which can be moved in an open or a closed position on guideways of the slide housing and in a relaxed position Spring organs swiveling slide unit is held.
- the slide unit is generally guided so that it can slide in a cover attached to the slide housing.
- a hinged cover is provided which is pivoted to the slide housing and in which the slide unit is guided in an adjustable manner and which is preferably fastened to the slide housing by four screws in the operating position.
- the slide unit is guided on guide strips which are screwed to the side wall of the slide housing. After loosening the clamping elements pressing the slide against the base plate and removing the guide strips, the slide unit can be removed from the slide housing.
- the housing is provided with a removable end wall, after its removal and after the tensioning members have been released, the slide unit can be moved out.
- the sliding closures are often dismantled after just one or two ladle castings for maintenance purposes and to replace the worn refractory plates.
- the screws mentioned must therefore be loosened each time and the slide unit must be removed from the slide housing and re-installed accordingly. Since these slide fasteners are mostly very hot and dirty during maintenance work, manual disassembly is relatively cumbersome. The assembly must also be carried out with the appropriate care, because the clamping screws, which are usually fastened with a torque wrench, require precise adjustment.
- the object of the present invention is to develop a slide closure of the type described in the introduction in such a way that its slide unit can be detached from the housing in a very simple and time-saving manner for the very frequent replacement of the refractory plates and spouts and can be put back into operating condition after the refractory has been replaced .
- this object is achieved in that the Slider unit is displaceable in a position lying outside the open and the closed position, in which the slider unit is pivotably supported in a bearing in the slider housing and the guideways are lowered relative to the guideways on the remaining path length by a height that relaxes the spring elements.
- the slide unit with the slide plate arranged therein is simply moved by moving it in the above-mentioned Relieved of the pressure from the spring elements. You can therefore dismantle the slide lock in an absolutely simple way by sliding the slide unit into the above. Position is driven and then swung out of the valve body. During assembly, the slide unit is swung back into the slide housing and then moved to the closed position. As a result, the pressurization of the spring organs is automatically restored without additional operations on the slide closure.
- the invention further provides that the slide unit designed as a slide carriage can be displaced with at least two elements, in particular rollers, mounted on guides of the slide housing on both sides.
- a housing frame which surrounds the slide carriage and to which the guides for the slide unit are fastened.
- the invention provides that the housing frame is held on both sides by two spring elements arranged symmetrically and axially parallel to the pouring opening on the upper part of the housing.
- the spring members expediently each consist of a bolt with an upper and a lower stop surface resting on the housing frame and a spring arranged in the upper housing part and acting on the upper stop surface.
- the housing frame is articulated around two bolts fastened in the upper housing part, which are arranged on a plane perpendicular to the direction of displacement and on the axis of the pouring opening.
- the bolts position the housing frame and at the same time prevent the resulting axial force from being applied to the springy tensioning elements of the lock.
- the slide carriage is pivotably articulated on the push rod of the slide carriage drive, and the guides for the slide unit point in the above-mentioned manner. Position below each roller on a recess with a length greater than the roller diameter, through which the rollers of the slide unit can be pushed. In addition to the very simple expansion or relaxation, this also ensures an absolutely simple disassembly or assembly of the slide carriage.
- the slide carriage has on both sides two rollers mounted on the guides of the housing frame and also an articulated hook acting on the push rod of the slide carriage drive.
- the guides in the above-mentioned position of the slide carriage below the coaxial bearings on the side of the slide carriage drive each have a recess with a length greater than the roller diameter, while the guides center the other two coaxially arranged rollers in the groove, and the slide unit in the above position about the axis of rotation of the rollers can be swiveled out while pivoting the articulated hook.
- the invention provides that the slide carriage is pivotally articulated on the push rod of the slide carriage drive.
- the housing frame is pivotally mounted on the valve body, and which in the above Guide tracks in contact with the rollers run approximately parallel to the guideways on the remaining track length and parallel to the direction of displacement.
- Fig. 1 shows a first embodiment of the invention
- FIG. 2 shows the sliding closure according to FIG. 1, shown in cross section
- Fig. 3 shows the slide closure of Fig. 1 with the slider unit pivoted out.
- Fig. 4 shows a longitudinal section through the slide closure according to Fig. 1 with a variant of the articulation of the slide unit.
- Fig. 5 shows a second embodiment of the invention
- Fig. 6 shows the slide closure according to Fig. 5 in cross section.
- the sliding closure 20 shown in FIG. 1 is attached to the steel jacket 12 of a partially illustrated steel melting pan 10.
- a refractory base plate 22 arranged in the upper housing part 26 of the closure 20 is sealingly connected to a spout 14 embedded in the refractory lining 16 of the pan 10 with an opening 15.
- the slide carriage 30 can move from an open position into a closed position S, which is shown in FIG. 1 is indicated by dash-dotted lines, and vice versa can be shifted by means of a drive.
- the drive which is not shown. it is usually a hydraulic cylinder with a push rod 28.
- the slide carriage 30 is held at one end by an articulated connection 29 on the push rod 28, this push rod 28 being additionally mounted in the upper housing part 26.
- the slide carriage 30 has on its two longitudinal sides two rotatably mounted rollers 36 with axes of rotation extending transversely to the direction of displacement. These rollers 36 are supported on guides 21 of the closure housing.
- the guides 21 are in turn attached to a housing frame 24 surrounding the slide carriage, which is held by spring members 50 on the upper housing part 26.
- the slide carriage 30 can be moved by the drive into an area lying outside the closed position, in which the guide tracks 21b in contact with the rollers 36 are lowered by a height h which relaxes the springs compared to the track in the operating state.
- These guideways 21b are inclined surfaces which cause a continuous increase in tensioning and a continuous reduction in spring tension when relaxing. After the inclined surfaces 21b, the guides 21 are interrupted by recesses 21c with a length greater than the roller diameter. As a result, the slide carriage 30 can be pivoted out of the housing and the regularly required replacement of the worn plates 22, 32 and of the interchangeable spout 34 can be carried out.
- the spring members 50 consist of a two-part bolt 52 and a spring 54 arranged in the upper housing part 26.
- the bolt 52 has a lower stop surface 52 '. on which the housing frame 24 rests, and an upper stop surface 52 'against which the spring 54 presses. For assembly purposes, it is divided into two and screwed together.
- the two spring members 50 are provided symmetrically and axially parallel to the pouring opening 15 and a bolt 60, which is located at the height of the pouring opening, is screwed into the upper housing part 26 and centers the housing frame 24, but with its spherical surface articulates it on all sides leaves.
- the springs should be dimensioned such that the slide plate 32 is pressed against the base plate 22 with a predetermined clamping force.
- Cover plates 58 fastened to the upper housing part 26 protect the spring elements against contamination.
- the slide plate 32 and the base plate 22 are held in a known manner in the slide unit 30 or in the upper housing part 26 by means of clamping means 38 or 27.
- a pan 10 After a pan 10 has been emptied, it is normally moved to a pan location for the purpose of maintenance and replacement of the wearing parts. There it is placed on its side so that the slide unit can be swung out horizontally.
- the slide unit moved after the pouring into the closed position is moved into the position shown in FIG. 3 by a cylinder located at the pan position and swung out to the dot-dash position in order to be able to easily replace the closure plates 22 and 32.
- the lock As soon as the lock has been serviced, it is made ready for operation and the slide unit is brought back into the closed position.
- a stop 25 which could be removably attached to the housing could be provided, by means of which the slide unit could not be moved into a position A lying outside the closed position.
- a stop 25 is indicated in Fig. 1. This is designed as an axis 25 and held extractable in the housing frame 24.
- the slide unit 80 has two rollers 86, 86 'on both sides.
- the rollers 86 arranged coaxially on the side of the drive element are in the outside of the The closed position S of the slide unit 80, position A, can be pushed through recesses 21 ′ provided in the guides 21. while the two coaxial rollers 86 'are surrounded and centered opposite one another in said position A by a groove 81'.
- the slide unit 80 is articulated by an articulated hook 89 on the push rod 28 of the drive element. it can be pivoted out in position A about the axis of rotation of the rollers 86 '.
- the slide closure 70 shown in FIG. 5 functions essentially similar to that shown in FIG. 1. Therefore, only the different features of this closure 70 compared to the closure 20 are explained below.
- the slide carriage 50 which is also pivotally articulated at one end by a joint 79 on the push rod 78 of a drive, not shown, with two rotatably mounted rollers 86 on each side, is slidably held in a cover 74 which is articulated on the housing 76 and can be swung out.
- the slide carriage 80 can in turn be moved by the drive into an area lying outside the closed position S, in which the guide tracks 71c in contact with the rollers 86 are lowered by a height h which relaxes the springs compared to the area of the tracks 71a which is in the operating state.
- the guide tracks 71c run parallel to the tracks 71a and also parallel to the direction of displacement of the slide carriage 80. Inclined surfaces 71b in turn ensure that the slide carriage is continuously relaxed or tensioned.
- the cover 74 is fastened to the housing 76 in a known manner by means of tensioning elements 75 (not shown in more detail).
- tensioning elements 75 (not shown in more detail).
- the spring members 90 are supported in the slide carriage 80 and press directly on the slide plate 82 in the operating state of the closure.
- the slide carriage is first moved into the relaxed position, then the cover 74 can be unscrewed from the housing 76 and how the slide carriage is also swung out, and the maintenance work already mentioned can then be carried out.
