Definitions

  • This invention relates to a cruicible or converter, particularly for carrying out top blowing processes.
  • Known crucibles for carrying out top blowing processes consist of a cylindrical or pear-shaped vessel which is provided with a refractory lining.
  • the tilt-bearing of such crucibles is mostly accomplished by means of carrier rings which are mounted to surround the shell of the vessels and to which trunnions are secured; or in the case of the so-called carrier-ringless crucibles the trunnions may be mounted directly to the crucible shell.
  • Such sealing elements consist, e.g., of a casing secured to the collar and surrounding the same with a clearance, the lower rim of said casing being adapted to be inserted into an annular edge arranged on the outer wall of the crucible and filled with a packing.
  • the invention solves this problem in that on top of the converter mouth a crucible sealing ring is placed, the inner wall of which is inclined towards the interior of the crucible, the vertically displaceable chimney por- 3,358,983 Patented Dec. 19, 1967 tion being adapted to be brought in engagement with the inclined surface of the crucible sealing ring.
  • the crucible sealing ring may consist of a box-type section of triangular cross section, the inner cavity of said box-type section being advantageously connected to a coolant supply conduit.
  • the sealing ring according to the invention may consist of one or several parts.
  • the parts may be moved into the operating position, e.g., on a horizontal sliding track.
  • the diameter of the lower rim of the vertically displaceable chimney portion is equal to or preferably a little smaller than the upper diameter of the sealing ring so that a sealing eflect is obtained in a simple manner by lowering the chimney. This enables collecting the waste gases without taking in infiltrated air.
  • an embodiment of the invention is diagrammatically represented in a vertical sectional view.
  • the upper part of a refractory-lined crucible is designated by 1.
  • the sheet metal shell ends with a T- shaped flange 2, the inwardly directed portion 3 of which borders the brick lining and the outwardly directed portion 4 of which serves for securing the sealing ring 5.
  • the sealing ring 5 consists of a box-type section of triangular cross section, the inner wall 6 having an inclination towards the interior of the crucible. Towards the outside the sealing ring has a flange 7, which is adapted to be connected to the flange 4 by means of screws 8. In larger crucibles the sealing ring 5 may be made of several parts and moved into the position shown in the drawing with the aid of sliding tracks or the like.
  • the interior of the sealing ring 5 communicates with conduits 9 and 10 which serve for the supply and discharge, respectively, of a coolant.
  • the collar-shaped chimney 11 is mounted to be vertically displaceable, as is indicated by the double arrow.
  • the diameter of the rim 12 of the chimney 11 is somewhat smaller than the upper opening of the sealing ring, which is formed by the inclined surfaces 6, so that any additional sealing means as have been previously required are rendered unnecessary.
  • a crucible assembly for carrying out top blowing processes, comprising a crucible having a mouth substantially at the top thereof, a vertically displaceable chimney portion for connecting said crucible mouth with a flue, and a hallow sealing ring on said crucible mouth, said sealing ring having a substantially triangular cross section so as to include a cavity and define an inner surface which is inclined towards the interior of said crucible, said vertically displaceable chimney portion being moveable into sealing engagement with said inclined inner surface of said sealing ring and out of engagement therewith, said cavity of said sealing ring communicating with a coolant supply conduit.
