Metallurgical vessel

A refractory lined metallurgical vessel having a generally horizontal tilt axis and a second axis generally normal to said tilt axis,

• generally hollow trunnion support means having an upper surface,
• adapter means,
• a plurality of mounting means for affixing said vessel to said adapter means,
• releasable coupling means for affixing said adapter means to said trunnion support means so that said vessel may be tilted to discharge metal therefrom, and
• said releasable coupling means comprising a first plurality of spaced apart apertures formed in said adapter means and a second plurality of spaced apart apertures formed in the upper surface of said trunnion support means,
• said first and second plurality of apertures being disposed equidistant from said second axis and in equiangular spaced relation thereto whereby rotation of said vessel about said second axis and relative to said trunnion support means will move different ones of said first plurality of apertures into and out of operative orientation with individual ones of said second plurality of apertures,
• a plurality of coupling members mounted in said trunnion support means for movement through said apertures when said adapter means is oriented such that the aperture therein is in registry with the aperture in the upper surface of said trunnion support means.
• and member support means within said trunnion support means for supporting said members adjacent the aperture in said trunnion support means and below the upper surface thereof so that release of said members will allow the same to move into said member support means whereby said vessel and adapter means may be rotated about said second axis relative to said trunnion support means.

A refractory lined metallurgical vessel having a generally horizontal tilt axis and a second axis generally normal to said tilt axis,

• generally annular trunnion support means having a generally planer upper surface,
• adapter means comprising a generally annular member,
• a plurality of mounting means for affixing said adapter means to said vessel,
• said adapter means having a generally planer lower surface presented toward said trunnion support means,
• releasable coupling means for affixing said adapter means to said trunnion support means so that said vessel may be tilted to discharge metal therefrom, and
• said releasable coupling means comprising a first plurality of spaced apart apertures formed in said adapter means and a second plurality of spaced apart apertures formed in the upper surface of said trunnion support means,
• said first and second plurality of apertures being disposed equidistant from said second axis and in equiangular spaced relation thereto whereby rotation of said vessel about said second axis and relative to said trunnion support means will move different ones of said first plurality of apertures into and out of operative orientation with individual ones of said second plurality of apertures,
• a plurality of coupling members mounted on one of said trunnion support means and adapter means for movement through said apertures when said adapter means is oriented such that the aperture therein is in registry with the aperture in the upper surface of said trunnion support.

A refractory lined metallurgical vessel,

• a generally annular trunnion support means having a generally planer upper surface,
• adapter means comprising a generally annular member affixed to said vessel and having a relatively planer lower surface presented toward the upper surface of said trunnion support means,
• a plurality of mounting means for affixing said vessel and to said adapter means,
• releasable coupling means for affixing said adapter means to said trunnion support means so that said vessel may be tilted to discharge metal therefrom, and
• said releasable coupling means including indexing means associated with said vessel and said trunnion support means and having a plurality of angularly related indexing positions whereby said adapter means may be affixed to said trunnion support means in each of a plurality of relative angular positions,
• said indexing means comprising a plurality of apertures in said adapter means and trunnion support means and members mounted on one of said adapter or trunnion support means and movable into and out of coupling engagement with said apertures and locking means associated with each of said members and selectively movable into and out of locking engagement therewith to secure said coupling members in said apertures.

A refractory lined metallurgical vessel,

• a trunnion support surrounding said vessel and having a top portion,
• generally annular adapter means,
• a plurality of mounting means for affixing said vessel to said adapter means,
• releasable coupling means for affixing said adapter means to said trunnion support so that said vessel may be tilted to discharge metal therefrom, and
• said releasable coupling means including a plurality of apertures formed in said adapter means and a plurality of members mounted on said trunnion support and each being receivable in one of said apertures when said vessel is in each of a plurality of angular positions relative to said trunnion support, and means for releasably securing said members in said apertues, whereby said adapter means may be affixed to said trunnion support in each of a plurality of relative angular positions.
