Metallurgical vessel capable of receiving fluids in separate flow paths while pivoting

A refractory lined metallurgical vessel having a trunnion support and a plurality of trunnion pin means extending from said support for being rotated to tilt the vessel about a generally horizontal axis,

• a plurality of tuyere means extending through the lining of said vessel and each including a pair of concentric spaced apart pipes for simultaneously providing plural fluids to said vessel,
• rotary joint means including first and second portions,
• the first portion of said rotary joint means including a first plurality of concentric, generally annular members spaced apart radially from each other and affixed to one of said trunnion pin means for rotation therewith, said one trunnion pin having an axially extending opening,
• said first plurality of members defining a first plurality of axially extending and radially spaced apart flow passages,
• the second portion of said rotary joint means including a second plurality of concentric, generally annular members which are spaced apart radially from each other, at least some of said second plurality of members being coradial with corresponding ones of said first plurality of members to define a second plurality of axially extending and concentric flow passages which have the same radial displacement as corresponding ones of said first plurality of flow passages,
• said first and second rotary joint portions being disposed in an abutting relation whereby at least some of said first plurality of flow passages communicate with corresponding ones of said second plurality of flow passages,
• a first and a second plurality of passageway means formed respectively in the first and second portions of said rotary joint means and extending at an angle relative to said tilt axis,
• each passageway means of said first plurality of passageway means being connected to a different one of the passages of said first plurality of flow passages,
• a first plurality of pipe means, each of said pipe means of said first plurality of pipe means being connected to a different one of said first passageway means and extending toward said one trunnion pin means, said pipe means converging toward said axis of rotation for passing through the axial opening in said one trunnion pin means,
• each passageway means of said second plurality of passageway means being connected to a different one of the flow passages of said second plurality of flow passages,
• a second plurality of pipe means, each of the pipe means of said second plurality of pipe means being connected to a different passageway means of said second plurality of passageway means,
• whereby each of said second plurality of passageways may be connected to a different source of process fluid for said vessel.

A metallurgical vessel having a plurality of tuyeres extending therethrough,

• a trunnion support coupled to said vessel and a plurality of trunnion pin means extending from said support for being rotated to tilt the vessel about a generally horizontal axis, one of said trunnion pin means having an axial opening formed therein,
• rotary joint means including first and second portions,
• the first portion of said rotary joint means including a first plurality of concentric, annular members spaced apart radially from each other and affixed to said one trunnion pin means for rotation therewith,
• the gaps between said first plurality of members defining a first plurality of axially extending and radially spaced apart flow passages,
• the second portion of said rotary joint means including a second plurality of concentric, annular members which are spaced apart radially from each other, at least some of said second plurality of members being coradial with corresponding ones of said first plurality of members to define a second plurality of axially extending and concentric flow passages which have the same radial displacement as corresponding ones of said first plurality of flow passages,
• said first and second rotary joint portions being disposed in an abutting relation whereby at least some of said first plurality of flow passages communicate with corresponding ones of said second plurality of flow passages,
• a first and second plurality of passageway means formed respectively in the first and second portions of said rotary joint means and each passageway means being connected to a different one respectively of said first and second plurality of flow passages,
• a first plurality of pipe means, each pipe means of said first plurality of pipe means being connected to a different passageway means of said first plurality of passageway means and extending to said vessel, and
• a second plurality of pipe means, each of the pipe means of said second plurality being connected to a different one of said second plurality of passageway means,
• whereby each of said second plurality of passageways may be connected to a different source of process fluid for said vessel.
