- FIG. 9 shows a further embodiment of a pressure device according to the invention.
- FIGS. 1 to 3 show a replaceable pouring tube 1 which, by means of a pouring tube changing device, is in a pouring position at the pouring spout of a pouring tube.
- nes metallurgical container is fixable.
- the container itself is not shown in the drawing, and of the Giessrohr circuitvorraum only three Anpressbolzen 2 can be seen.
- the spring-loaded pressure pins 2 act on the pouring tube 1 and press it in a casting position either directly to a refractory sleeve of the container or to a closure plate of a sliding closure attached to the container.
- the casting tube 1 has a pouring opening 3 and comprises a coaxial to Giessö Maschinensachse a, lower tubular part 4 and an upper plate 5.
- the plate 5 has on its underside two on both sides of the tubular part 4 arranged guide surfaces 10 which are inclined in the casting direction directed downwards and form a downwardly tapering plate cross-section.
- the angle ⁇ , the guide surfaces 10 include the Giessö Maschinensachse a, 20 ° to 80 °, preferably 45 °, as shown, amount.
- the pouring tube 1 for the purpose of Auswechseins transversely to the casting direction, in the direction A of Fig. 3, adjusted and a new pouring tube 1 are brought back into the casting position.
- the two guide surfaces 10 of the plate 5 are curved in their longitudinal direction or in the adjustment direction A of the pouring tube 1, this stepped wise or convex or bent in a similar manner, such as oval, a polygon, approximately circular etc. They are advantageously with respect to a the Giessö Stammsachse a comprehensive, extending in the direction A center plane of the plate 5 convexly curved, wherein the radius of curvature Rl (Fig. 3) is greater than the maximum distance of the respective guide surface 10 from the casting opening axis a comprehensive center plane of the plate fifth
- the contact pins 2 are each resiliently pressed against the guide surfaces 10 by a head 2a, which is convexly curved in the adjustment direction A of the casting tube 1 and has a radius of curvature R3 (FIG. 3).
- the pressure pins 2 are in line contact with the guide surfaces 10.
- the pressure forces exerted on the plate 5 by the pressure bolts 2 arranged parallel to one another do not run parallel, but are distributed more in the center and thus more evenly distributed.
- three contact pins 2 each act on the respective guide surface 10.
- the number of contact pins 2 could be chosen differently.
- the head height and / or the spring stroke of the individual adjoining Anpressbolzen 2 of the curvature of each Weil matched guide surface 10 and thus optimizes the clamping force.
- the guide surfaces 10 which are curved in their longitudinal direction or in the adjustment direction A of the pouring tube 1 extend obliquely downwardly in a vertical section, as can be seen in particular in FIG.
- Fig. 4 shows a pouring tube 1 'with a plate 5', the guide surfaces 10 'in turn in their longitudinal direction or in the adjustment A of the pouring tube 1 have a radius of curvature R4, but in addition are also convex in vertical cross-section, i. have a curvature outwards with a radius R2.
- the radius of curvature R4 of the guide surfaces 10 'in the adjustment direction A is eccentric with respect to the casting opening axis a, similar to the embodiment according to FIGS. 1 to 3.
- the guide surfaces 10 " which are curved in their longitudinal direction or in the adjustment direction A of the casting tube 1, are also arched outwards in the vertical cross section with a radius R5.
- this is a so-called oblique circle variant, in which the curvature having the radius R5 is additionally embodied in an oblique position, for example, of 45 ° to the pouring opening axis a.
- FIG. 4 and FIG. 5 are in the adjustment direction A of the casting tube 1 'and 1 "convexly curved contact pressure pin 2 in a point contact with the corresponding guide surfaces 10' and 10", wherein on the plate. 5 'or 5 "pressure forces exerted evenly distributed, as in known Giesrohren with even guide surfaces.
- FIG. 6 and FIG. 7 show a variant of a casting tube 61, which in itself has the same design as that of FIG. 1 to FIG. 3 and therefore the differences are explained below.
- This casting tube 61 is likewise provided with these guide surfaces 60 according to the invention, which are directed obliquely downward in the casting direction and form a plate cross-section tapering downwards.
- the main difference with respect to the guide surfaces 10 of Figure 1 is that their radius of curvature R6 is in each case in a horizontal orientation, i. is formed perpendicular to the axis a. This radius of curvature R6 is again greater by a multiple than the radius of the tubular part 64 of the pouring tube 61.
- FIG. 8 an exemplary embodiment of a contact pressure device 50 according to the invention is illustrated with pressure bolts 2 'arranged perpendicularly or radially to the guide surface 10. There are the four pressure pins 2 'and acting on this, coaxial with the Anpressbolzen 2' disposed spring 51 housed in a housing 52, from which of course the convexly curved in the adjustment direction A heads 2a 'protrude at least partially.
- the pressing device 70 has a simple, compact design.
- FIG. 9 shows a further embodiment of a casting tube changing device 70 according to the invention, in which the respective pressing element is not designed as a pressure pin, but as a rocker arm 72, whose one arm 73 is connected to the head 72a which is convexly curved in the adjustment direction A of the casting tube provided and another arm 74 is loaded by a spring 71. While the contact pressure of the head, in turn, for example, at an angle of 45 ° to the vertical Giessrohrachse, the respective spring 71 is arranged horizontally. This construction is more complicated than that of FIG. 8 and requires more space, but here the heat on the springs 71 is smaller.
- the formed radius of curvature of the respective guide surface extends either perpendicularly or at an angle (eg 45 °) to the axis a of the pouring tube.
- this angle could also be approximately 0 °, ie the radius of curvature would then be aligned parallel to the axis a. Depending on how chosen this angle is, this affects the shape of the guide surface in their longitudinal training.
- the pressure bolts could also be arranged perpendicular to the curved guide surfaces or to the sections forming the curvature.
- the pressure bolts could also be in surface contact with the guide surfaces, at least in the casting position, instead of in line contact.
