Claims
- 1. An apparatus for mounting a gas washing sink in a centered manner within an opening through a perforated brick in a wall of a metallurgical vessel, to enable gas to be introduced through the sink into molten metal within the vessel, and for removing the sink from the perforated brick, said apparatus comprising:
- a support assembly to be fixedly mounted on the exterior of the wall of the metallurgical vessel adjacent the opening in the perforated brick;
- fastening means including mounting means for mounting the sink at a position centered relative to said fastening means, said fastening means being mounted with respect to said support assembly for movement relative thereto between an operating position, whereat the sink is pressed into the opening through the perforated brick in a centered manner, and a maintenance position, whereat said fastening means is centered with respect to the opening through the perforated brick and thereby the sink is withdrawn from the opening through the perforated brick;
- means, operable between said support assembly and said fastening means, for moving said fastening means and thereby the sink relative to said support assembly to said operating position; and
- withdrawal means, operable between said support assembly and said fastening means, for moving said fastening means and thereby the sink relative to said support assembly from said operating position to said maintenance position.
- 2. An apparatus as claimed in claim 1, wherein said support assembly includes at least one column, and said fastening means comprises at least one member movable relative to said column.
- 3. An apparatus as claimed in claim 2, comprising at least two said columns.
- 4. An apparatus as claimed in claim 2, including two said columns, and said member comprises a cross member having opposite ends with bores therethrough, said columns extending through respective said bores, and said cross member being slidable in opposite directions relative to said columns.
- 5. An apparatus as claimed in claim 4, further comprising a closure member supported by said cross member and movable therewith to sealingly press against the sink.
- 6. An apparatus as claimed in claim 5, further comprising a gas inlet connection connected to said closure member.
- 7. An apparatus as claimed in claim 5, wherein said closure member includes a seal ring to seal against the sink.
- 8. An apparatus as claimed in claim 2, wherein said support assembly further includes a pivot axis, and said at least one member comprises a lever assembly pivotable about said axis.
- 9. An apparatus as claimed in claim 8, further comprising a closure member supported by said lever assembly and movable therewith.
- 10. An apparatus as claimed in claim 9, further comprising a gas inlet connection connected to said closure member.
- 11. An apparatus as claimed in claim 9, wherein said mounting means comprises means for connecting said closure member to the sink.
- 12. An apparatus as claimed in claim 11, wherein said connecting means comprises a centering ring attached to said closure member and having a contact surface to be complementary to the peripheral surface of the sink.
- 13. An apparatus as claimed in claim 12, further comprising means for detachably connecting said centering ring to said closure member.
- 14. An apparatus as claimed in claim 8, wherein said lever assembly has a construction such that, upon pivoting thereof about said axis from said operating position to said maintenance position, said lever assembly first moves the sink in an outward direction substantially perpendicular to the plane of the opening in the perforated brick and then in a curved direction.
- 15. An apparatus as claimed in claim 14, wherein said support assembly further includes a stop for limiting movement of said lever assembly and thereby to define said maintenance position.
- 16. An apparatus as claimed in claim 1, further comprising a casing removably attachable to said fastening means and having an outer contour corresponding to the outer contour of the sink, whereby said casing is insertable in a centered manner by said fastening means into a worn opening in the perforated brick to thereby form a template defining the contour of the opening in a worn portion of the perforated brick to enable the repair thereof.
