MOUNTING FOR INVERTIBLE VESSEL Filed Nov. 8, 1961 2 Sheets-Sheet 2 United States Patent O M' 3,146,983 MUNTING F1111 INVER'HBLE VESSEL Paul R. Johnson, @als Ilan/n, lll., assigner to Chicago Bridge Iron Company, Chicago, Ill., a corporation oi illinois Filed Nov. 8, 1961, Ser. No. 151,021 10 Claims. (Cl. 248-141) The present invention relates generally to mountings for invertible vessels such as converter vessels used in the oxygen process of steel-making, and more particularly to a mounting which accommodates thermal expansion of the vessel and avoids a vertical drop by the vessel, relative to its mounting, when the vessel is inverted.
Converters used in the oxygen steel-making process generally comprise an opentop vessel, a peripheral ring connected to the vessel and spaced radially therefrom to accommodate thermal expansion by the vessel in a radial direction, a pair of trunnions extending in opposite directions from the ring, and a pair of standards each rotatably mounting one of said trunnions. Conventional converter vessels are mounted on the peripheral ring by upper and lower brackets each rigidly attached to the converter and connected to the ring.
During the steel-making operation the shell of the vessel becomes hotter than the radially spaced peripheral ring and undergoes greater expansion, in both vertical and radial directions, than does the ring. As a result, the upper and lower brackets, rigidly attached to the shell of the vessel, are moved further apart in a vertical direction. This causes a loosening of the connection between the brackets and the ring. Accordingly, when the converter is inverted to pour out the molten steel, there is a vertical drop by the vessel relative to the ring and equal to the diierence between the distances separating the upper and lower brackets before and after expansion. This drop causes a substantial impact shock to the ring 4and the vessel, said shock being of a magnitude which can damage the converter.
The present invention provides an arrangement which mounts the vessel to the ring, which accommodates both radial and vertical expansion of the vessel relative to the ring, and which avoids a vertical drop by the vessel, and its resultant impact shock, when the converter is inverted. The mounting arrangement of the present invention also maintains the converter vessel centrally within the trunnion ring under all conditions of expansion and in all positions of rotation.
Other features and advantages are inherent in the structure claimed and disclosed or will become apparent to those skilled in the art from the following detailed description in conjunction with the accompanying diagrammatic drawings, wherein:
FIGURE l is a front elevational view, partly in section, of a steel-making converter including an embodiment of a mounting arrangement, for the converter vessel, constructed in accordance with the present invention;
FIGURE 2 is an enlarged fragmentary side View of a portion of the converter of FIGURE 1;
FIGURE 3 is a sectional view taken along line 3 3 in FIGURE 2;
FIGURE 4 is a fragmentary sectional view illustrating in detail an embodiment of the subject mounting arrangement when the converter is in an unheated condition;
FIGURE 5 is a view similar to FIGURE 4, illustrating the mounting arrangement with the converter in a heated condition; and
FIGURE 6 is a fragmentary front view of the mounting arrangement of FIGURES 4 and 5.
FIGURE l illustrates a typical steel-making converter vessel 1S having an upper opening 19, a tap-hole nozzle 16, an interior lining of refractory material Ztl, and con- 3,146,983 Patented Sept. 1., 1964 ICC nected to a radial spaced peripheral ring 17 by a plurality of peripherally spaced hinged connections 40. Extending outwardly from ring 17 in opposite directions are a pair of horizontal trunnions 13, 14, journalled in bearings 11, 12 supported by standards 9, 1G. Trunnion 14 is connected by a coupling 3l? to means (not shown) for rotating the trunnions and inverting converter vessel 1S.
Hinged connections 41D entirely support vessel 18 when the latter is in a vertical position, right side up as in FIG- URE l or inverted, and partially support vessel 13 when it is tilted. Located above and below each trunnion 13, 14 are lugs 31, 32 respectively, each attached to vessel 18 (FIGURES 2 and 3). When the vessel is in a horizontal tilted position, the lugs 31, 32 rest on ring 17 to provide substantially the entire support for the vessel, and when the vessel is tilted to an inclined position it is partially supported by the lugs.
The shell of vessel 18 becomes hotter during the steelmaking operation than does ring 17, spaced outwardly from vessel 18. Accordingly, vessel 1S undergoes a greater amount of thermal expansion in both radial and vertical directions than does ring 17. FIGURES 4 to 6 illustrate in detail hinged connecting means 40 which mount the converter 1S on the ring 17, which accommodate the difference in radial and vertical expansion between vessel 13 and ring 17, and which avoid a vertical drop by vessel 18, relative to ring 17, when the converter is inverted.
Referring to FIGURES 2 and 3, in the illustrated embodiment, ring 17 is hollow and comprises outer and inner walls 45, 46 respectively, upper and lower walls 47, 48 respectively, and internal rigidifying diaphragme 49. Referring now to FIGURES 4 to 6, rigidly attached to ring upper Wall 47, as by welding, is an element 44 the upper part of which is pivotally connected by a pin 43 to the lower end of each of a pair of link members 40a, 4Gb each each disposed on an opposite side of element 44. The upper end of each link member 40a, 4tlb is in turn pivotally connected by a pin 41 to the lower part of a substantially triangular shaped element 42 located between the two link members, rigidly connected to the shell of vessel 1S, and vertically aligned With element 44. Pins 41, 43 include head portions 33, 34 and have nuts 35, 36 threaded thereon to maintain them in place (FIGURE 6). Pin 41 has an axis which, except for the slight spacing of pin 41 from the surface of vessel 18, is tangential to or extends alongside the surface of vessel 18. Pin 43 has an axis parallel to the axis of pin 41. Both pin axes are substantially horizontal when the vessel is in the upright position shown in the figures. The pin axes are horizontal when the ring is horizontal. The pins 41, 43 and their respective axes are spaced apart a predetermined distance, and this distance is maintained for all positions of rotation of the converter vessel by verture of the construction of connecting means 40.
FIGURE 4 illustrates the relative positions of ring 17, vessel 18 and hinged connecting means 40 before thermal expansion, while FIGURE 5 illustrates the relative position of the ring, the vessel and the hinged connecting means after thermal expansion. Converter vessel 18 undergoes thermal expansion in both a radial and vertical direction, said expansion being substantially greater than that undergone by ring 17. Accordingly, the walls of converter vessel 18 expand radially and vertically relative 'to ring 17. This expansion is accommodated by the clearance 61 existing between inner wall 46 of ring 17 and the shell of vessel 18, and by hinged connecting means 40 which maintain the desired connection between the ring and the vessel during this differential expansion and avoid a vertical drop on the part of vessel 18 when the converter is inverted.
The link members 40a, 4Gb, by virtue of being positioned on each side of and attached to both element 44 on ring 17 and element 42 on vessel 18, act as guides for these elements during expansion and help maintain the alignment between the elements during expansion. This in turn helps maintain converter vessel 18 centrally within trunnion ring 17 during expansion and rotation. Other guide means which help to maintain vessel 1S centrally within the trunnion ring under all conditions of expansion and in all positions of rotation are located above and below trunnions 13, 14 on lugs 31, 32 and ring 17.
Referring to FIGURES 2 and 3, lugs 31, 32 each include peripherally spaced outwardly extending portions 51, and mounted on ring upper and lower walls 47, 48 are peripherally spaced, normally vertically extending mem bers 52. Each portion 51 is received and confined between a pair of members 52 which act as guides for portion 51 as the latter moves outwardly during radial expansion of converter vessel 18.
It should be noted that neither portions 51 nor any other portions of the lugs rest on ring upper wall 47 when vessel 18 is in an upright vertical position, or on,
ring lower wall 48 when the vessel is in an inverted vertical position. However, when the vessel is in other than a vertical position, portions 51 rest on members 52, and when the vessel is in a horizontal position the sole support for the vessel is provided by lug portions 51 resting on members S2.
Each of the peripherally spaced hinged connections 40 is protected from the heat emanating from the vessels upper opening 19 and from particles blown outwardly through the opening 19 by a downwardly and outwardly flaring peripheral shield 54 connected to the shell of converter vessel 18 by fasteners 53 attaching the shield to plates S6 on elements 42.
There has thus been described an arrangement which mounts a converter vessel on a spaced peripheral ring, which accommodates for the difference in expansion between the vessel and the ring during heat-generating operations inside of the vessel, and which avoids a vertical drop on the part of the vessel relative to the ring when the converter is inverted.
The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, as modifications will be obvious to those skilled in the art.
