Definitions

  • An upper group of pairs of diagonally-opposed mounting assemblies constitute the main mounting and supporting means for the vessel and an aligned lower group serve to supplement the support when the vessel is tilted from a vertical towards a horizontal position, all while permitting the vessel to expand and contract peripherally, vertically or longitudinally, laterally or transversely.
  • Unique gib or keeper and wedge elements are employed for adjustablyconnecting or adjustably-slidably-clamping the vessel on its trunnion ring.
  • the invention pertains to an improved mounting and support for a molten material handling or processing vessel such as a furnace vessel, and particularly to a so-called stabilizing type of trunnion mounting which makes use of gibs or keepers having cooperating wedging elements, that are carried by the trunnion ring. and that cooperate with associated mounting brackets that are secured to project from the vessel.
  • Metal mounting and handling vessels such as oxygen blow or converter vessels used for melting and refining ferrous metal customarily employ a trunnion ring for supporting the vessel and for tilting it on a pair of trunnion shafts that are carried by the ring and that are adapted to be positioned on a pair of supports or bearings stands to facilitate refining, pouring and charging operation.
  • Such vessels have been progressively increasing in size and now are available in capacities up to about 350 tons.
  • the heavy mass or weight of the vessel and the weight of the molten metal which tends to shift in the vessel when it is tilted during its operation, and the high temperatures in the neighborhood of 3500 F. to which the vessel may be subjected all necessitate special means for supporting and connecting the vessel with respect to its trunnion ring or outer, centrally-positioned mounting structure.
  • the present invention deals with bracket and keeper or gib assembly which are constructed to provide an improved guide mounting for a vessel with respect to its trunnion ring, such as to provide an adjustable, stable type of physical change permitting support of its metal shell wall.
  • Another object has been to employ a combination of wedging means for providing an improved stabilized mounting of a vessel.
  • a further object of the invention has been to devise a supporting structure for a vessel that utilizes cooperating pairs of wedge elements for adjusting its mounted relation, both vertically and transversely with respect to its trunnion ring and with reference to its main support brackets.
  • a still further object has been to devise a mounting or supporting assembly utilizing the upper and lower brackets and keeper or gib assemblies, wherein the top or upper assemblies serve as main supporting assemblies for the vessel, and lower assemblies serve as a guide and tilt support for the vessel, and wherein both the upper and lower assemblies have tapered wedging elements for adjusting the engagement of their cooperating surfaces with respect to each other.
