Definitions

  • ABSTRACT A spout for a metallurgical vessel including a refractory brick and a refractory sleeve includes a cylindrical ring fixed to the inner surface of the vessel jacket opening and having abutment surfaces for centrally positioning the brick and sleeve and for vertically p0- sitioning the brick.
  • known spouts including a slide closure are associated with the disadvantage that the forces acting during operation within the vessel on the apertured brick and the forces outside the vessel resulting from the movement of the slide and acting on the bottom plate, may lead to cracks in the mortar joints. This presents a substantial problem in attempting to achieve operational reliability, since the mortar sealing joints between the elements are stressed by the full hydrostatic pressure of the metal melt. Hence it is desirable to adopt measures for eliminating the influence of these forces, or at least to substantially reduce such influence.
  • the invention involves the replacement of parts which are subjected to wear, in particular on a spout equipped with a slide closure, whereby it is possible to provide for rapid and reliable mounting and assembly of the sleeve and the apertured brick, while at the same time substantially eliminating the insufficiencies and risks that are involved in previously known manual handling methods.
  • the adjusting and holding means position the sleeve and the apertured brick firmly in the desired assembled position, thus insuring that they are immovably positioned during later operation and use.
  • an advantageous structure is that the ring has a smaller diameter stepped portion positioned coaxially inwardly toward the longitudinal axis of the ring.
  • the inner stepped surface provides an abutment for the sleeve, while the outer stepped surface provides an abutment for the apertured brick.
  • a slide closure is attached to the outer surface of jacket I for the purpose of opening and closing flow passage 8 of sleeve 7.
  • the slide closure includes a frame 13, a slide housing 14, and a housing cover 15 including slide guides or tracks 16 on which a displaceable supporting slide 17 can be reciprocated by means of an operating rod 18.
  • Slide 17 carries a refractory slide plate 19 and an outwardly depending refractory outflow sleeve 20.
  • Plate 19 and sleeve 20 are provided with coaxial outlet openings 21 and 22, respectively, and are sealed by a suitable mortar to slide 17.
  • Above slide plate 19, a stationary bottom orifice plate 23 is arranged such that its flow opening 24 is aligned with flow passage 8 of sleeve 7.
  • Bottom plate- 23 and sleeve 7, and slide plate 19 and outflow sleeve 20, are respectively connected tightly by means of splined interlocking joints and by a suitable mortar.
  • plates 23 and 19 and sleeves 7 and 20 are parts that are subjected to wear and which must routinely be replaced. In connection with their replacement, refractory apertured brick 5 may also be replaced if necessary.
  • a cylindrical ring 36 is provided at the lower end thereof with an inwardly extending horizontal annular flange 37.
  • the crosssection of ring 36 is angular.
  • Brick 5 is centered by means of the vertical inner surface 38 of ring 36, and its vertical position is determined by the upper horizontal surface 39 of flange 37.
  • Sleeve 7 is centered by the inner annular surface 40 of flange 37, while the upper vertical position of sleeve 7 is determined in the same manner as in the embodiment of FIG. 1, i.e. by conical inner surface 28 of passage 6 of brick 5.
  • a spout for metallurgical vessels particularly including an exterior metal jacket with an opening therein, a refractory lining with an opening therein aligned with said jacket opening, a slide closure, a refractory apertured brick mounted in said opening of said refractory lining of said vessel and accessible from the interior of said vessel, and a refractory sleeve mounted in the aperture of said brick and removable outwardly therefrom, the improvement comprising:
