Definitions

  • the invention relates to a refractory plate with an elongated, round design and a shrink ring, which is drawn onto the peripheral surface, for clamping in metallic frames of sliding closures on the pouring of metallurgical vessels.
  • the shrink ring holds the refractory plate material together in such a way that despite the thermal stresses when first used occurring thermal stress cracks, the second sliding surface can still be used.
  • the relatively long straight longitudinal surfaces on the circumference of the plate proved to be weak points at which the shrink ring rarely fits snugly, which promotes crack formation.
  • Such destructive effects on the circumferential surface are also targeted and punctually introduced clamping forces of the clamping means for immovably holding the plate in its metallic frame.
  • an ellipse-like plate is known, which is mounted without play with play in the metallic frame of the closure. Otherwise, the plate has a wedge surface on the circumference for mechanical clamping of a multi-part, correspondingly wedge-shaped clamping ring, which is intended to counteract thermal stresses in the plate material. It is disadvantageous that the relatively stiff clamping ring on the contact surface to the plate creates the fire-resistant structure early destructive pressure points.
  • the object of the present invention is to improve plates according to the type set out at the beginning with simple shaping means with regard to manufacture and durability.
  • an elliptical peripheral surface of the plate has, at least on one main apex side, a clamping surface formed transversely to the main axis of the plate ellipse and receiving the clamping pressure.
  • This outer shape of the plate with a special clamping surface on the otherwise continuously rounded circumferential surface allows the shrink ring to fit snugly against the longitudinal sides of the plate with even full application in the region of the clamping surface, so that there is an improved cohesion of the plate structure and thus a longer service life of the plate.
  • a symmetrical shape of the plate is advantageously provided, according to which mutually parallel surfaces are arranged on both main apex sides of the plate, one of which serves as an abutment surface with respect to the plate frame.
  • the two surfaces are perpendicular to the main axis of the plate ellipse.
  • Another proposal of the invention is that the large radii of the plate ellipse are two to three times the intended plate width. This makes it possible to keep the refractory volume to a minimum and thus reduce the manufacturing costs of the board.
  • 1 means the metallic slide frame of a slide closure used on metallurgical vessels.
  • the frame figure 1 which can be adjusted in the longitudinal direction by means of a connecting rod which can be connected to 2, the elliptical refractory slide plate 3 is clamped, which has a flow opening 4, two of which can also be provided, and usually cooperates with an identical stationary plate check the spout as a function of the closure.
  • each of the identical plates 3 designed as an ellipse with a main axis 5 is circumferentially provided with a shrink ring 6 that is narrower than the plate thickness and is reversible in that both plate levels are machined as sliding surfaces.
  • a special clamping surface 7 is provided on a main apex side of the plate 3 in order to absorb the clamping force of a clamping device 8, the clamping jaw 9 of which is in guide connection with a wedge piece 11 arranged on a threaded bolt 10 and is pivotably supported on the frame 1.
  • the clamping jaw 9 can be moved towards or away from the clamping surface 7 by correspondingly turning the threaded bolt 10 on the actuating profile 12.
  • Another surface 13 similar to the clamping surface 7 is provided on the other main apex side of the plate 3. Both surfaces 7 and 13 are parallel to one another with respect to the length of the main axis 5 and transversely, mainly perpendicular, to the main axis 5, although slight deviations from the vertical can also be constructively useful.
  • the clamped plate 3 is supported via the surface 13 with respect to the frame 1, which has a correspondingly designed counter-profile surface or, alternatively, a second clamping device 8.
  • the plate 3 rests on the frame base 14 and is loosely guided over the peripheral surface of the frame borders 16, so that when the chipboard is open device 8 an exchange or turning the plate 3 is easily possible.
  • the plate 3 can be clamped in the frame 1 in a manner that is reliable and largely free of tension.
