Definitions

  • a starter bar composed of flexible fabricated sections hinged together. Each section is made up of top and bottom plates spaced apart by a plurality of lengths of sheet-piling section or rectangular-section tubing disposed transversely, joined together and secured loosely to the plates which are themselves discontinuous. Terminal blocks secured to the ends of the plates are adapted to receive hinge pins joining adjacent sections,
  • This invention relates to a flexible starter bar for use in continuous casting and, in particular, to a bar adapted for cooperation with a slab-casting tnold.
  • my improved starter bar comprises a plurality of sections hinged together end-to-end.
  • Each section is an elongated flexible fabricated structure having a cross-sectional shape and size about the same as that of the casting to be formed.
  • the structure of each section eX- tends between spaced terminal hinge-pin blocks and includes a chain of lengths of sheet-piling section or lengths of tubing of rectangular section disposed transversely and pivotally connectedl
  • Top and bottom plates overlie these lengths and are loosely connected thereto. The plates are jointed and the portions thereof have a limited degree of articulation.
  • FIGURE 1 is a diagrammatic elevation with a portion in section, showing my starter bar in a continuous-casting apparatus
  • FIGURE 2 is a plan view of one of the sections of my starter bar with parts broken away;
  • FIGURE 3 shows a portion of FIGURE 2 to enlarged scale
  • FIGURE 4 is a section along the plane of line IV-IV of FIGURE 3 with a portion in elevation;
  • FIGURE 5 is a cross-section along the plane of line V-V of FIGURE 3.
  • sections 10 of which my starter bar is composed are elongated fabricated structures having terminal blocks 11 and 12 with hinge-pin lugs 13 drilled as at 14 to receive suitable pins 16 by which a plurality of the sections may be pivotally connected end-to-end as shown in FIGURE l.
  • a chain of transversely disposed lengths 15 of sheet-piling section having their edges pivotally interconnected.
  • Filler bars 15a are welded in the grooves at the edges of the lengths 15 to reduce the slack or lost motion therebetween, without limiting freedom of pivotal movement.
  • Gusset bars 17 extend across lengths 15 and are welded thereto.
  • Top and bottom plates 18 and 19 are loosely connected to lengths 15 by headed pins or rivets 20 extending through holes in the lengths which are larger than the shanks of the pins and welded into holes through the plates in which the pins iit snugly.
  • Bearing plates 21 are disposed between the lengths 15 and plates 18 and 19. The latter are jointed as at 22 and ends of the several portions are of dovetail shape. The extreme end portions of the plates are secured to blocks 11 and 12 by bolts 23. The edges of the fabri cated structure are closed by jointed strip lengths 24.
  • sections 10 when coupled together end-to-end form a flexible thrust element with a mold bottom plate 25 at the upper end which may be pushed upwardly between the guide rollers 26 defining the desired curved path for the casting and the pinch rolls 28 which lcontrol the descent thereof from mold 29. That is to say, the starter bar composed of a string of sections 10, has sufficient flexibility to conform to the curvature of the path between rollers 26 but also sufficient rigidity so it will not buckle under the compressive force which must be applied from below to place the starter bar in proper position initially.
  • FIG- URES 6-8 The modified form of the invention shown in FIG- URES 6-8 is generally similar to the preferred embodiment described above, except that, for the lengths 15 of sheet-piling section, I substitute lengths 30 of rectangularsection tubing. These lengths are disposed in pairs, generally transversely to the length of the section 10 but at a slight angle thereto, the lengths of each pair being inclined at opposite angles forming a herringbone or chevron pattern.
  • Lengths 30 are slotted inwardly from their outer ends as shown at 31 and longitudinal bars 32 fitted into these slots extend between hinge blocks 11 and 12 and are welded thereto.
  • Filler plates 33 are fitted in the ends of the lengths and welded thereto.
  • Top and bottom cover plates 18 and 19 overlie lengths 30 and extend between blocks 1,1 and 12. They are loosely Isecured to the tubing lengths by pins 20.
  • pins 34 extend through the top and bottom plates, bars 32 and each of the tubing lengths 30, being welded to the plates. The tubing lengths, while positioned close together, are slightly spaced by shirns 35.
  • a starter bar for continuous casting composed of a plurality of sections pivotally connected end-to-end, each section comprising an elongated flexible structure including spaced terminal blocks, a series of abutting lengths of rolled section disposed transversely of said structure and pivotally interconnected extending between said 5.
