Description
1~336~7 BACKGROUND OF THE INVENTION
-One prior art vessel support is disclosed in United States Patent No. 3,146,983 wherein a plurality of links pivotally connect a convertor vessel to the upper trunnion ring flange to support the vessel in a vertical position and to allow differential expansion between the vessel and the ring. However, these links are incapable of supporting the vessel when it is tilted to a generally horizontal position. Accordingly, in such prior art ves-sel suspension systems, it was necessary to provide aplurality of brackets adjacent the trunnion pin for sup-porting the vessel while the same was being turned up and turned down.
This invention relates to metallurgical vessels and more specifically, with a system for mounting said vessels to a trunnion ring.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a new and improved supp~rt for pneumatic metallurgical vessels.
A further object of the invention is to provide a metallurgical vessel suspension system which supports the vessel in its vertical and tilted positions and per-mits differential expansion between the vessel and a sur-rounding trunnion ring.
A further objbct of the invention is to provide aconvertor vessel suspension system wherein mechanical load is relatively uniformly distributed around the trunnion ring.

113~7 Still another object of the invention is to pro-vide a support for convertor vessels which does not restrict axial vessel expansion.
These and further objects of the invention will become more apparent from the deiailed description of the invention taken with the accompanying drawings~
BRIEF DESCRIPTION OF THE DRAWINGS
FIGURE 1 is a side elevational view with parts broken away schematically illustrating a convertor vessel having a suspension system according to the present inven-tion;
FIGURE 2 is a cross-sectional view showing the suspension system of FIGURE 1 in greater detail;
FIGURE 3 is a view taken along lines 3 - 3 o FIGURE 2;
FIGURE 4 is a view taken along lines 4 - 4 of FIGURE 2;
FIGURE 5 illustrates one varia'ion of a portion of the suspension assembly according to the invention; ana FIGURE 6 shows an alternate variation of a por-tion of the suspension assembly according to the present invention.
FIGURE 1 shows a convertor vessel 10 which is one example of a metallurgical vessel to which the suspen-sion system according to the present invention is applic-able. As those skilled in the art will appreciate, how-ever, the suspension system is applicable to any metallur-gical vessel which is supported within a so-called trunnion ring. The vessel 10 is shown to include a metallic shell 12 ~;:
~336~7 and a refractory lining 13. A top opening 14 permits charging of the vessei with hot metal or scrap. The ves-sel 10 may also have a pouring spout 15 which permits the discharge of its contents into a ladle or other suitable receptacle when the vessel is tipped.
As seen in FIGURE 1, the vessel 10 is surrounded by a concentric trunnion ring 16. Extending from each of the diametrically operative sides of trunnion ring 16 are a pair of coaxial trunnion pins 17, only one of which is seen in FIGURE 1. Pins 17 are usually journaled in suit-able supports (not shown) and are coupled to a suitable drive mechanism (not shown) which provides the requisite torque for tilting the trunnion ring 16 and the vessel 10 which it supports. The trunnion pins 17 may also be hol-low so as to allow the entry and exit of cooling water tothe interior of trunnion ring 16. In the illustrated ex-amples, the interior of trunnion ring 16 is intended to be water-cooled but the specific details of construction are omitted since they are well-known in the art and form no part of the present invention.
Trunnion ring 16 is shown in FIGURES 1 and 2 to include a rop ring-like flange 20 and a similar bottom flange 21 which is spaced from top flange 20 and is arranged in a generally concentric parallel relation with respect thereto. The flanges 20 and 21 are joined at their edges by an annular inner wrapper plate 22 and an annular outer wrapper plate 23 which is concentric with wrapper plate 22 and spaced therefrom in a generally parallel relation.
The joints between flanges 20 and 21 and wrapper plates 22 and 23 may be secured in any suitable manner such as by li~, ~336~7 welding. It will also be appreciated that trunnion ring 16 in the illustrated example is essentially a hollow, circular box girder. While not shown in the drawings, trunnion ring 16 may also be reinforced internally by a series of circum-fèrentially spaced radially disposed plates each of whichhas an aperture to permit the circulation of cooling water, if desired. It will also be apparent that the uessel sus-pension system according to the present invention is appli-cable whether the trunnion ring 16 has a configuration illustrated in FI~URES 1 and 2 or is in another form such as an I-beam, channel or various other cross-sectional shapes.
The vessel 10 is supported on the trunnion ring 16 by an upper suspension assembly 26 and a lower suspen-sion assembly 28. The upper suspension assembly 26 in-cludes a clamp ring 30 which engages the upper flange 20 and a plurality of generally triangular links 32 which are pivotally connected at their lower ends to the ring 28 and at their upper ends to the vessel 12. Ring 28 is generally co-radial with top flange 20 and may comprise a single member or a plurality of arcuate segments. In transverse cross-section, ring 28 is generally ~-shaped with its large leg 34 disposed above and extending parallel to top flange 20. Leg 34 of ring 28 may engage flange 20 dir-ectly or a thin metallic shock absorber pad 36 may be dis-posed therebetween. The shorter leg 38 of clamp ring 28 extends downwardly behind the inner edge of flange 20.
Each link 32 includes a relatively thick base portion 40 which tapers down to a thin neck portion 42.
11336~7 The base portion 40 of each link 32 is pivotally mounted between a pair of upstanding brackets 44 which are affixed in spaced apart relation to the upper surface of clamp ring 32. Specifically, a pivot bolt 46 extends through aligned holes 48 in brackets 44 and a bore 30 extending through base portion 40. The neck portion 42 of each link 32 is similarly pivotally mounted to vessel 10 by means of a pivot bolt 52 extending through bores 54 in neck portion 42 and aligned apertures 56 in brackets 58 which are affixed in parallel, spaced apart relation to a ring 60 secured to the shell 12 generally above trunnion ring 16.
The bores 50 and 52 through each link 32 are generally parallel so that the links may pivot simultaneously at its upper and lower ends relative to clamp ring 30 and ~essel shell 12. Also, each of bolts 46 and 52 may be threaded at one end so that they may be suitably retained in posi-tion such as by means of nuts 62.
The lower suspension assembly 28 includes a sec-ond clamp ring 64 which is configured similarly to the upper clamp ring 30 and a plurality of links 65. The long leg 66 of ring 64 is disposed in a generally parallel rela-tion to the lower flange 21 and there are a plurality of spaced apart disk springs 68 disposed therebetween. The short leg 70 of ring 64 also hooks behind the lower inside edge of flange 21.
Each of the links 65 includes a pair of eye-bolts each of which includes a head portion 74 having a trans-verse aperture 76 and a threaded shank 78. An internally threaded sleeve 80 engages each of the shanks 78 so that .
the distance between the apertures 76 and hence, the length ~336g7 of each link 65 may be adjusted. The lower end of each link 65 is pivotally mounted by means of a bolt 81 between a pair of brackets 82 affixed in spaced apart parallel re-lation to a second ring 84 affixed generally below trunnion ring 16. Bolts 81 extend through apertures 76 and aligned holes 86 in brackets 82. The upper end of each link 65 is similarly pivotally mounted by means of bolts 88 between a second pair of brackets 89-affixed to a lower surface of clamp ring 64. Bolts 88 extend between holes 92 in brackets 88 and through apertures 76 in the upper ends of links 65.
The bolts 81 and 88 are arranged in a generally parallel relation to permit simultaneous pivotal movement of links 65 at their opposite ends and each is threaded at one end for being secured by means of bolts 94.
While brackets 58 and 82 are shown in FIGURE 2 to have substantially the same height as their respective rings 16 and 84, they may, for added strength, be of in-creased height and have portions (not shownj which engage and are affixed to the surface of shell 12.
In the preferred embodiment of the invention shown in FIGURE 5, all of the upper links 32 are arranged such that their relatively larger base portions 40 are attached to upper clamp ring 30 and their relatively smaller neck portions 42 are pivotally connected to ring 60. In the al-ternate embodiment of the invention shown in FIGURE 6, how-ever, alternate links 32~ are inverted so that their base portions 40 are pivotally connected to ring 60 while their smaller neck portions 42 are pivotally connected to clamp ring 30.
11336~7 It will be appreciated that there are a plurality of l:Lnks 32 of the upper suspension assembly 26 and a plur-ality of links 65 of the lower suspension assembly 28 which are disposed in spaced apart relation around the vessel 10 and all are pivotally connected to the vessel shell 12 and to the respective upper and lower clamp rings 30 and 64 in the mannèr discussed with respect to FIGURES 2-4. This permits differential radial expansion of the vessel 10 and the trunnion ring 16 as the links 32 and 65 are free to pivot at their opposite ends. For example, should the vessel 10 expand radially to a greater degree than trunnion ring 16, thereby moving the shell toward the right relative to trunnion ring 16 as viewed in FIGURE 2, the link 32 will tend to pivot clockwise about bolts 52 and 46 and the link 65 will pivoc counterclockwise about bolts 81 and 88.
Similar pivotal movement in the links 32 and 65 will occur should the vessel grow lengthwise as a result of the tem-peratures and stresses inherent in its operation. In addi-tion, the links 32 not only support the vessel when it is in a vertical position, but the links 32 and 65 also fur-nish support for the vessel when it is in its various inter-mediate tilted positions and when it is turned up and turned down.
The clamp rings 30 and 64 absorb radial loading from the links 32 and 65 so as to minimize radial stress in the trunnion ring flanges 20 and 21. In addition, the clamp rings 30 and 64 distribute the compressive loads rel-atively evenly to the trunnion ring when the vessel is ver-tical. Further, the links 32 and 65 prevent lateral shift-ing of the vessel during turn-up and turn-down. This is ~1336~7 particularly enhanced by the upper links 32 which resist sidewise deflection as a result of their generally triangu-lar configuration. The spring washers 68 between the lower clamp ring 64 and trunnion ring 16 permit relative movement between the clamp ring 64 and the trunnion ring 16 so that links may also be used below the trunnion ring for support during tilting and when the vessel is inverted. As a result, brackets employed in prior art systems to support the ves-sel during turn-up and turn-down is not re~uired. Addition-ally, the adjustability of links 65 allow changes in lengthnecessitated by changes in vessel dimensions during opera-tion.
While only a few embodiments of the invention have been illustrated and described, it is not intended to 1~ be limited thereby but only by the scope of the àppended claims.
