Definitions

  • the prior art devices for cooling a continuous casting wheel incorporates in addition to the conventional main elements or means employed by the casting wheels in machines of this type, a plurality of cooling casings appropriately arranged at the periphery of the wheel, near the groove formed in the periphery of the wheel, to constitute in combination with the belt closing the said groove, the mold into the interior of which there is to be introduced a molten metal which, after cooling, will form the product which it is desired to obtain.
  • the cooling casings previously proposed by the Applicant in the above-identified applications permit the systematic sprinkling and spraying of the greater portion of the lateral surfaces of the casting wheel, and also of the belt for closing the groove formed'in the wheel.
  • the flange of the casting wheel is no longer of Y-section, but has the shape of an open U which is substantially widened out or flared towards the exterior, the two legs and the base of the U constituting, together with the coveringbelt, the mold proper. This may be said, to some extent, to amount to the suppression of the tail of the aforementioned Y.
  • This construction makes it possible, in an extremely advantageous manner, to cool equally well the now freed" portion of the flange surface, which said portion is directed towards the interior of the wheel.
  • the securing of the lugs is preferably resilient in such manner as to take into account the expansion caused by heat.
  • the latter may be slightly notched opposite each lug.
  • the wheel hub will also be freed by restricting to the strict minimum the number of contact surfaces or ridges between the flange and the hub, while making use of the notches thus obtained in the periphery of the hub for providing for the sprinkling of the convex face of the flange atthat point in a known manner.
  • FIG. I is a radial section through the peripheral portion of a casting wheel constructed according to the invention.
  • FIG. 2 is a detail view of a portion of the surface of connection between the casting wheel and the hub thereof.
  • the wheel flange 1 has a U-shaped cross-section, as seen in FIG. 1, the thickness of which is practically uniform, and which is open and upwardly flared, with the base portion being of slightly oval shape.
  • the belt 2 is used for closing the mold, the section of the latter thus being of substantially trapezoidal shape, wherein the long base is radially outward and the two ridges or edges at the apex are slightly rounded.
  • the lugs or projections 3 and 4 are provided for securing the wheel I to the hub 7, which said lugs or projections engage in notches 5 and 6 formed for this purpose in the thickness of the two limbs of the U- shaped wheel 1.
  • the hub 7 is formed with bores 8 through which extend the bolts 9 for securing the lugs 3 and 4.
  • a seat is formed in the outer face of each of the lugs 3 and 4, to
  • this seat serves for containing the head 12 of the bolt 9.
  • the external surface of the flanges 3 and 4 may comprise cooling fins 13 (shown in thin lines in FIG. 1) the purpose of which it is to increase the heat exchange surface between the flange and the cooling fluid.
  • one of the lugs may be formed integral with a wheel hub 7.
  • FIG. 2 A developed view of the manner of construction of the surface of this connection'is shown in FIG. 2.
  • the surface of the hub 7 is formed with a predetermined number of teeth or projections 14 which alone contact the flange l.
  • a device for the cooling of a continuous casting wheel comprising a peripheral wheel flange removably secured on a central hub, a casting groove formed in the external periphery of said flange and being covered by an appropriate belt, said cooling device being characterized in that the cross-section of said casting groove is U-shaped, the aperture 'of said U being directed radially outward toward the exterior, and further including a plurality of cooling spaces formed between the inner periphery of said flange and the outer periphery of said hub.
  • a device according to claim 1 characterized in that the walls of said casting groove are of substantially uniform thickness.
  • a device further comprising lugs 'or projections fitted on said hub and arranged in pairs, to constitute gripper elements for clamping said flange to effect the securing of the wheel flange on the hub.
  • a device characterized in that, the securing of the wheel flange onto said hub is effected by means of lugs fitted on said hub and being disposed alternatinglyon either side of said hub.
  • a device characterized in that the lugs'are of small thickness in the circumferential direction.
  • the gripping means are resilient and lock at one of their ends, the lugs against the wheel hub, the flange being clamped and maintained in posite ends of the lugs.
  • a device characterized in that the flange is formed with notches ,in which are lodged the associated ends of the lugs.
  • a device characterized in that the portions of the lugs facing the inner periphery of the flange are shaped as to afford a free space on the I side of the said inner periphery.
  • a device characterized in that the central hub has formed on its external periphery, atleast three teeth which, alone, provide for contact with the inner periphery of the flange.
  • a device according toclaim 1 characterized in that the radially inward bottom of the flange is subjected to the action of a cooling fluid.
