Definitions

  • the invention relates to a refractory plate with an elongated round or oval shape and a flat on the U fangsf drawn
  • Shrink ring for clamping in metallic frames of sliding closures on the spout of metallurgical vessels.
  • the shrink ring holds the refractory plate material together in such a way that despite the thermal stresses at the first Use occurring thermal stress cracks, the second sliding surface is still usable.
  • the relatively long straight longitudinal surfaces on the plate circumference proved to be weak points where the shrink ring rarely fits snugly, which favors cracking.
  • 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.
  • 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.
  • the object is achieved according to the invention essentially in that an elliptical peripheral surface of the plate at least at a Haupttscheitelse te a transverse to the main axis of the plate ellipse, the clamping pressure receiving clamping surface.
  • This outer shape of the plate with a special clamping surface on the otherwise continuously rounded circumferential surface allows a full nestling of the shrink ring on the longitudinal sides of the plate with uniform full application in the area 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.
  • Figure 1 shows a refractory plate clamped in an adjustable linear slide frame according to the invention in plan view
  • Figure 2 shows a longitudinal section through the plate removed from the frame.
  • 1 means the metallic slide frame of a slide closure used on metallurgical vessels.
  • 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 in order to Check the function of the closure to check the spout.
  • each of the identical plates 3, which are designed as an ellipse with a main axis 5, is provided on the circumference with a shrink ring 6 which 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.
  • Another surface 13 similar to the clamping surface 7 is provided on the other main apex of the plate 3. Both surfaces 7 and 13 are parallel to each other 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 over 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 clamping device 8 is open, an exchange or turning of the plate 3 is easily possible.
  • the plate 3 can be clamped in the frame 1 in an operationally reliable and largely stress-free manner.

Abstract

Plaque ignifuge, de configuration ronde ou ovale dans le sens longitudinal, comportant une bague de serrage sur la surface périphérique. Ladite plaque est améliorée grâce à une conformation extérieure, une surface périphérique elliptique (15) présentant une surface de serrage (7) recevant la pression de serrage et configurée transversalement par rapport à l'axe principal (5) de l'ellipse, au moins sur un côté du sommet principal. On empêche ainsi la formation de fissures et la durée de vie s'en trouve accrue.
