Definitions

  • the invention relates to a casting tube changing device for fixing a replaceable, for exchanging transversely to the casting direction adjustable pouring tube in a casting position at the spout of a metallurgical container, according to the preamble of claim 1.
  • the publication EP-B-1 590 114 discloses a casting tube comprising a lower tubular part coaxial with the casting opening axis and an upper plate. On the underside of the plate flat guide surfaces are arranged on both sides of the tubular member, which are directed obliquely downwards in the casting direction and form a downwardly tapering plate cross-section.
  • the replaceable casting tube is fixed in a casting position by means of a casting tube changing device acting on the guide surfaces, which comprises at least one spring-loaded pressure element which can be pressed against one guide surface of the casting tube.
  • a changing device for a dip tube comprises on both sides of the spout opening arranged spring-loaded rocker arm, which press a respective dip tube to an upper refractory sleeve.
  • the rocker arms each have a guide surface for the dip tubes, which are aligned approximately horizontally and cause a force upward in the axial direction of the spout opening of the dip tube.
  • the present invention has for its object to provide a Giessrohr pleavortechnisch of the aforementioned type, which allows in conjunction with particularly advantageous trained guide surfaces of the Giessrohres optimal pressure force transmission.
  • the respective pressing element is pressed with a curved in the adjustment direction of the pouring tube stepwise or convex or similar head to a curved in its longitudinal direction or in the adjustment direction guide surface of the pouring tube, whereby the pressure forces exerted by the Anpressbolzen optimally, more against the G manrohrö réelle out and thus more evenly acting, transferred.
  • the risk that in particular at the transition from the plate to the tubular part in refractory material cracks occur significantly reduced.
  • better centering of the pouring tube is achieved in Giessposition.
  • Fig.1 to 3 an interchangeable pouring tube 1 is shown, which by means of a Giessrohr pleavortechnisch in a casting position at the spout of a metallurgical container is fixable.
  • the container itself is not shown in the drawing, and of the Giessrohr grillvortechnik 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 replacing transversely to the casting direction, in the direction A to 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 stepwise or convex or bent in a similar manner, such as oval, a polygon, approximately circular, etc.
  • they are convexly curved with respect to a center plane of the plate 5 which extends in the direction of the casting opening axis a, the radius of curvature R1 (FIG. Fig. 3 ) is greater than the maximum distance of the respective guide surface 10 of 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 with 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. Fig. 3 ) having.
  • 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.
  • the risk that in particular at the transition from the plate 5 to the tubular part 4 in the refractory material cracks substantially reduced (both the tubular part 4 and the plate 5 are made of a refractory material that at least in the plate area of a metal jacket. 9 is surrounded).
  • 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 each juxtaposed contact pin 2 of the curvature of the respective Guide surface 10 adapted and thus optimizes the clamping force.
  • Fig. 1 to 3 illustrated embodiment of the pouring tube 1 extend in its longitudinal direction or in the adjustment direction A of the pouring tube 1 curved, obliquely downwardly directed guide surfaces 10 seen in vertical section straight, which is particularly in Fig. 2 is apparent.
  • Fig. 4 shows a casting 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, ie a curvature to the outside with a Have radius R2.
  • the radius of curvature R4 of the guide surfaces 10 'in the adjustment direction A is eccentric with respect to the Giessö Stammsachse a, similar to the embodiment according to Fig. 1 to 3 ,
  • Fig. 5 illustrated variant of a pouring tube 1 "are curved in their longitudinal direction or in the adjustment direction A of the pouring spout 1 guide surfaces 10" also curved in the vertical cross-section to the outside with a radius R5.
  • R5 the radius of curvature of the guide surfaces 10 "in the adjustment direction A is concerned.
  • 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. 6 and Fig. 7 show a variant of a Giessohres 61, which is the same in itself as that after Fig. 1 to Fig. 3 and therefore now 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 compared to the guide surfaces 10 after Fig. 1 is that their radius of curvature R6 each in a horizontal orientation. ie 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 is an embodiment of an inventive pressing device 50 with perpendicular or radially to the guide surface 10 arranged Anpressbolzen 2 'illustrated. 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 novel casting tube changing device 70, in which the respective contact element is not designed as a Anpressbolzen, but as a rocker arm 72, one arm 73 provided with the in the adjustment direction A of the spout convex head 72a and another arm 74 of a spring 71 is loaded. 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 the one after Fig. 8 and takes up 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.
