Definitions

  • the invention relates to a metallurgical vessel, in particular a tiltable cast steel ladle, with a hinged lid hinged to the vessel by means of at least one hinge joint.
  • a metallurgical vessel of this type is known from Stahl und Eisen 100 (1980), No. 18, pages 1045 to 1050.
  • the hinged lid serves to avoid high temperature losses during the pouring of the melt and to maintain the inherent heat of the empty vessel.
  • the hinge joint is formed by an open hook rigidly attached to the vessel, into which a hinge pin attached to the hinged lid engages on a type of eyelet.
  • the hinged lid automatically opens and closes the vessel depending on the tilting position of the vessel.
  • a plug pin is provided which surrounds the hook on the side opposite the hinge pin and is inserted into the eyelet.
  • the hinged lid is secured by means of tension chains that can be attached to the hinged lid on the one hand and to the vessel on the other.
  • the invention aims to avoid these disadvantages and difficulties and has as its object to provide a metallurgical vessel of the type described above, the hinged lid of which can be placed on and removed from the vessel in a simple manner and without requiring manual manipulations and which is securely anchored to the vessel in all possible working positions of the vessel.
  • a hinge pin and a concentric to the hinge pin and arranged at a distance from it, but which extends only over a portion of the circumference of the hinge pin, is provided on the vessel, and on the hinged cover between the hinge pin and the link guide projecting hinge hook surrounding the hinge bolt over a maximum of 180 ° of its circumference is fastened, the hook opening of the hinge hook expediently pointing upwards when the vessel is upright and closed with the hinged lid, and the free end of the hinge hook is directed away from the hinged lid.
  • the hinged cover By guiding the hinge hook between the hinge pin and the link guide arranged concentrically to this, the hinged cover can be swung open without being able to be lifted from the vessel until the free end of the open hinge hook passes the end of the link guide. After this position has been reached, the hinged lid can be conveniently lifted up using a hoist or, in this opened position, can be hooked into the hinge pin from above.
  • Adequate securing of the hinged lid against falling when the hinged lid is opened is preferably ensured in that the link guide extends concentrically with the hinge pin over approximately a quarter of the circumference of the hinge pin facing the vessel.
  • the link guide is advantageously provided with an extension which extends vertically upward when the vessel is upright, which simplifies the hanging of the hinged lid, since the free end of the hinge hook is guided on the extension of the link guide.
  • the hinge hook preferably surrounds the hinge pin over at least 160 ° of its circumference, as a result of which the hinged lid can be pivoted by a pivoting angle of at least 160 ° or secured against unintentional or intended removal, or the vessel can be tilted slightly less than this angle.
  • the hinge pin is arranged laterally above the upper edge of the vessel and the hinge hook is rigidly attached to the hinged lid, which results in the resulting geometrical center of gravity, the possibility that the hinged lid when tilting the vessel already before a tilt angle of the vessel of 90 ° to the vertical automatically moves away from the edge of the vessel.
  • the resulting gap between the rim of the vessel and the hinged lid allows the liquid contents to be poured out of the vessel without it coming into contact with the hinged lid and contaminating it.
  • the hinge pin is arranged laterally below the upper edge of the vessel and the hinge hook on the hinged lid is mounted so as to be pivotable about a pivot axis directed parallel to the hinge pin and above the upper edge of the vessel, wherein stops are expediently provided on the hinged lid which prevent the pivoting movement of the hinge hook limit a range between 5 to 30 ° starting from a vertical position when the vessel is upright and closed with the hinged lid up to a position pivoted outwards from this vertical position to 5 to 30 ° .
  • the hinge hook is preferably guided laterally between the hinge cheeks that hold the hinge bolts and are attached to the vessel, which results in good lateral guidance of the hinged cover adjusts, so that under certain circumstances one can find enough with a single hinge joint.
  • FIG. 1 illustrating a partially sectioned side view of a metallurgical vessel with a hinged lid in the closed position according to a first embodiment.
  • Fig. 2 shows the vessel with the hinged lid so far open that it can be removed from the vessel.
  • FIG. 3 shows, in a representation analogous to FIG. 1, a metallurgical vessel according to a second embodiment.
  • FIG. 4 the vessel according to FIG. 3 is in a position tilted by approximately 90 °.
  • FIG. 5 shows, in an illustration analogous to FIG. 2, the vessel according to FIG. 3 with the hinged lid opened up to the lifting position.
  • a metallurgical vessel 1 designed as a ladle for a steel mill is provided with a hinged lid 2.
  • the ladle 1 can be tilted about two pivot pins 4 provided diametrically on its outer wall 3.
  • the hinged lid 2 is pivotally connected to the ladle 1 by means of a hinge joint 5, this hinge joint being arranged in a plane through the vertical axis 6 of the ladle 1 having a circular cross section.
  • the hinge joint 5 is formed by a hinge pin 7 and a hinge hook 8 which interacts with it, the hinge pin 7 being arranged between two hinge cheeks 9 fastened to the outer wall of the vessel 1.
  • the hinge cheeks 9 project laterally from the outer wall 3 to above the upper edge 10 of the vessel 1, so that the hinge pin 7 also comes to lie laterally and above the upper edge 10 of the vessel 1.
  • the hinge pin 7 is surrounded over part of its circumference by a link guide 11, the link guide 11 also being inserted between the hinge cheeks 9 and fastened to them.
  • the link guide 11 extends over approximately a quarter of the circumference of the hinge pin 7 facing the casting ladle 1 and is formed concentrically to the latter.
  • the link guide 11 has an extension 12 which extends vertically upwards beyond the horizontal plane 14 through the horizontal axis 13 of the hinge pin 7 with the vessel 1 upright and which extends the link guide 11 which is concentric with the hinge pin 7.
  • the hinge hook 8 is rigidly attached to a bracket 16 projecting above the hinged lid 2 and outwardly beyond the hinged lid circumference 15. It is designed as an open hook, the free end 17 of the hinge hook 8 being directed away from the hinged cover 2.
  • the hook opening 18 of the hinge hook 8 is directed upwards when the vessel 1 is upright and closed with the hinged lid 2.
  • the hinge hook 8 is inserted between the hinge pin 7 and the link guide 11 and wraps around the hinge pin 7 by approximately 180 ° .
  • the hinged cover 2 As can be seen in particular from FIG. 2, for the purpose of removing the hinged lid 2 from the vessel 1, it is necessary to open it by at least 180 °. Only after pivoting the hinged cover 2 by this angle can the hinged cover 2 be lifted off the vessel 1, since only then the hinge hook 8 is released from the link guide 11.
  • the pivoting angle a around which the hinged lid 2 has to be swung open, in order to be able to remove it from the vessel 1, corresponds approximately to the wrap angle beta of the hinge hook 8 around the hinge pin 7.
  • the wrap angle ⁇ is preferably at least 160 °.
  • a major advantage of the vessel 1 according to the invention can be seen in the fact that when the hinged lid 2 is mounted, this is well supported on the vessel 1 and conveniently in the closed position after the hinge hook 8 has been hooked into the hinge pin 7 - in an open position by approximately 180 ° or above can be folded, which is preferably accomplished by means of a hoist, such as the overhead crane, the hook of which is hooked into eyelets (not shown) provided on the hinged cover 2 for this purpose.
  • a hoist such as the overhead crane
  • the hinge hook 8 is articulated to the bracket 16 of the hinged cover 2 by means of a pivot axis 19 arranged parallel to the hinge pin 7.
  • the hinge pin 7 is arranged laterally below the upper edge 10 of the vessel 1, which is also designed as a ladle, and the pivot axis 19 is arranged above the upper edge 10 of the vessel 1 and approximately vertically above the hinge pin 7 (when the vessel 1 is upright).
  • a stop 20 is rigidly fixed, which limits the pivoting mobility of the hinge hook 8 about its pivot axis 19, so that the hinge hook 8 from its vertical position shown in FIG.
  • the invention is not limited to the exemplary embodiments shown in the description of the figures, but can be modified in various ways.
  • a single hinge joint 5 it is possible to provide two of them, which are arranged symmetrically to a vertical center plane of the vessel 1.
  • the direction in which the hook opening 18 is open can also deviate from the vertical direction when the vessel 1 is upright and closed.
