Definitions

  • the invention relates to a closing and regulating element for tapping liquid molten metal from a metallurgical vessel with a stationary inner tube which is arranged on the bottom of the vessel and has at least one opening above the bottom, and with an outer tube which has an at its lower end has circumferential end edge around the circumference of the inner tube and which is displaceable relative to the inner tube in the longitudinal axis direction by a closing stroke into a closed position from an open position in which the opening of the inner tube coincides with an opening in the outer tube.
  • Such a locking and control element is described in DE 35 40 202 C1.
  • the outer tube can be rotated to regulate the melt outlet and can be moved in the longitudinal direction.
  • the openings in the inner tube are covered by a corresponding rotation or displacement of the outer tube, so that no melt escapes in this closed position.
  • the outer tube according to DE 35 40 202 C1 is displaced by its maximum closing stroke in the longitudinal axis direction, then there is a distance between its lower end edge and the bottom of the vessel. In this area, the inner tube is exposed to the melt. Any cracks present there are not covered by the outer tube, so that melt breakthrough is not excluded there. In addition, with a maximum displacement in the closed position, the outer tube strikes the upper end edge of the inner tube lying in it. The inner tube is thereby mechanically loaded, which increases the formation of cracks and thus the risk of the melt breaking through. Overall, the closing and regulating device of DE 35 40 202 C1 therefore does not have sufficient emergency closing properties.
  • the object of the invention is to propose a closing and regulating element of the type mentioned at the outset which has the necessary emergency closing properties.
  • the above object is achieved in a closing and regulating element of the type mentioned at the outset in that the possible closing stroke is so large that the outer tube is in Is displaceable in the longitudinal direction in a further closed position, and that in the further closed position the opening of the inner tube is also covered by the outer tube and the front edge of the lower end of the outer tube sits sealingly on an annular surface which extends around the inner tube.
  • the outer tube is moved as in the prior art.
  • the outer tube is quickly moved in the longitudinal axis direction until it hits the end face of the ring surface. It does not hit the top of the inner tube. By seating the front edge of the outer tube on the ring surface, an additional sealing zone is formed.
  • the annular surface lies in the plane of the bottom of the vessel. This ensures that the portion of the inner tube projecting into the vessel is surrounded by the outer tube during the emergency closure and is thus covered against the melt.
  • the annular surface is preferably formed by the bottom of the vessel itself. However, it is also possible to design the ring surface as an external step of the inner tube.
  • a closing and control element (1) consists of an inner tube (2) and an outer tube (3). Both are made of ceramic, fireproof material.
  • the inner tube (2) is mortared in an airtight and meltproof manner in a base (4) of a metallurgical vessel.
  • the longitudinal axis of the inner tube (2) is perpendicular to the floor (4).
  • the inner tube (2) is provided with openings (5) above the base (4).
  • the inner tube (2) is closed at its upper end (6).
  • the outer tube (3) is pushed onto the inner tube (2) and can be rotated about the longitudinal axis and displaceable in the longitudinal axis direction.
  • the outer tube (3) is provided with openings (7) corresponding to the openings (5). Below the openings (7), the outer tube (3) has an end edge (8) running around the inner tube (2).
  • the end (6) of the inner tube (2) is closed like a dome.
  • the outer tube (3) is provided with a curvature (9) corresponding to the domed end (6).
  • annular surface (10) is formed from the bottom (4) in the vicinity of the inner tube (2).
  • the annular surface (10) is formed by a step (11) of the inner tube (2).
  • the ring surface (10) is also in the plane of the bottom (4).
  • the dimensioning of the inner tube (2) in the area of the openings (5) is weaker than that of the outer tube (3).
  • the dimensioning of the inner tube (2) below the step (11) is stronger than above the step (11).
  • the closing and regulating element (1) is shown in the open position, in which the openings (5) in the inner tube (2) are aligned with the openings (7) in the outer tube (3). Melt flows out of the vessel through the openings (5, 7) from the inner tube (2) downwards. The melt flow can be varied by rotating or moving the outer tube (3).
  • the outer tube (3) is moved in the direction of the arrow (N) until its front edge (8) hits the ring surface (10). This position is shown in dashed lines in Figures 1 and 2.
  • the outer tube (3) covers the openings (5) of the inner tube (2) and encloses the inner tube (2) over its entire length standing inside the vessel. This ensures that melt can no longer escape, even if there are breaks or gaps in the inner tube (2).
