Definitions

  • An apparatus for continuous vertical casting which includes extenders for adapting a casting frame for use with molds of different format including a member extending crosswise between the frame and mold to support the mold on the frame and to guide coolant liquid from the frame onto the outer walls of the mold.
  • slabs or billets can be made by vertically casting a molten material, such as a metal or alloy, into a mold with vertical generatrices having an internal cavity defining the product to be cast.
  • the mold is cooled to enable the material to harden.
  • cooling is obtained by allowing a liquid, such as water, to trickle down over the outer wall of the mold.
  • the mold is surrounded at its upper end by a chamber, known as a casting frame, provided with openings through which the cooling liquid flows.
  • the mold is usually supported by the upper part of the casting frame, as by means of a flange machined in a manner to insure that the mold remains centered within the frame.
  • the distance between the inner wall of the casting frame and the outer wall of the mold is governed by the pressure of the cooling liquid so as to obtain effective cooling.
  • a disadvantage of this arrangement is that the dimensions of the mold can be varied only within narrow limits if it is desired to maintain a proper sprinkling action. Accordingly, a separate casting frame has to be used for each mold having different format of product to be cast.
  • FIG. 1 is a sectional elevational view through a portion of a universal apparatus for continuous casting embodying the features of this invention
  • FIG. 2 is a sectional view taken along the line a-a of FIG. 1;
  • FIG. 3 is a perspective view of a modification in the apparatus for installing a short mold in an elongate casting frame;
  • FIG. 4 is a top plan view of the apparatus shown in FIG 3'
  • FIG. 5 is a top plan view of a further modification adapting the apparatus for use with a narrow mold in a wide casting frame;
  • FIG. 6 is a top plan view of a still further modification for adapting a short, narrow mold in a wide and long casting frame.
  • FIG. 7 is a sectional view taken along the line bb of FIG 6.
  • the apparatus embodying the features of this invention comprises a casting frame and a mold of conventional construction between which is arranged at least one water sheet extender in which each extender is formed with an upper portion in the form of a mold support having at least one of its side edges resting on the casting frame and a fourth side edge providing a support for the mold and in which the extender includes a lower portion in the form of a deflector for lateral transport of the cooling water from the casting frame to the mold walls.
  • the deflector has at least one of the following features, namely;
  • h universal apparatus of this invention comprises a casting frame 1, a mold 2, a water sheet extender dimensioned to extend across the space between the outer periphery of the mold and the casting frame and having an upper portion 3 in the form of a mold support and a lower portion 4 in the form of a deflector with a space between the upper and lower portions to provide a channel through which the cooling liquid, such as water, is transported from the casting frame to the mold.
  • the casting frame is of conventional design. It is provided with openings 11 on a horizontal axis.
  • the mold 2 has an inner wall of any desirable section, the generatrices of which are substantially parallel to a vertical axis 21.
  • the mold 2 is also formed with an outwardly extending horizontally disposed flange 23 which, in a conventional arrangement, is adapted to rest upon the upper surface of the frame 1.
  • the mold support is provided with a horizontally disposed flange 32 adapted to rest on the upper surface of the frame and, at the other end, adjacent the mold, the mold support is provided with a horizontally disposed groove 31 adapted to receive the flange 23 of the mold.
  • the deflector portion 4 is fixed in spaced relation beneath the support 3 by bolts 45 and studs 44 in between.
  • a channel section is thus provided between the deflector portion 4 and the mold support 3 into which cooling liquid flows from the openings 11 in frame 1.
  • the cooling liquid flows horizontally across the channel in the direction of the arrow 10 for release adjacent the outer wall of the mold to enable the cooling liquid to trickle down the outer wall 22 of the mold.
  • the portion of the deflector adjacent the casting frame Adjacent the mold 2, the deflector is formed with a smooth horizontally disposed ledge 43 in its upper surface to enable the sheet of liquid to spread out and the ledge terminates preferably in a draft edge 42 to prevent accumulation of liquid on the deflector and to enable a sheet of liquid to be formed for transfer to the outer wall 22 of the mold to cool the mold.
  • FIG. 3 and 4 illustrate the manner in which a short mold 2 can be installed in a casting frame I originally designed for a longer mold.
  • an extender 3, 4 of rectangular shape is arranged on either side of the small side of the mold with three horizontally disposed edge flanges 32 resting on the upper face of the casting frame 1 while its groove 31 receives the flange 23 of the mold.
  • a narrow mold 5 may be adapted to be installed in a casting frame 1 designed for a wider mold, as shown in FIG. 5,
  • an extender is provided on either side of the ledge face of the mold in which the mold support 30 comprises three horizontally disposed edge flanges 302 resting on the upper face of the casting frame 1 and a groove 301 which receives the flange 23 of the mold.
  • a first empty space corresponding to the width of the mold is created by providing along the long faces of the casting frame 1 long extenders 3040 having horizontally disposed edge flanges 302 resting on the upper face of the casting frame, The length of this first space is then reduced to a length corresponding to that of the mold by arranging along the narrow side of the empty space short extenders 3-4 hav' ing flanges 32 resting on the upper face of the casting frame 1 for one side of the extender and in grooves 301 in the extenders 30 -40 for the two other sides of the extender.
  • the flange 23 of the mold rests on that portion of the grooves 301 which remain unoccupied by the extenders 34 and in the grooves 31 of the extenders 3.
  • the cooling liquid generally water
  • the cooling liquid flows in the direction of the arrow and, in the extender 3-4, it flows perpendicularly of the figure. It is almost possible to extend extenders 3--4 as wide as the casting frame 1 and extenders 30-40 as long as the mold--this would merely result in a change in the dimensions of the rectangularly shaped extenders.
  • An apparatus for continuous casting which enables products of different format and dimension to be cast without change in the casting frame comprising a mold having outer and inner walls defining a vertically disposed cavity therein, a casting frame surrounding the mold with a spaced relationship between the frame and mold and having openings in a wall of the casting frame for the passage of cooling liquid therethrough, at least one water sheet extender across the space between the mold and casting frame including an upper portion having at least one side resting on the casting frame and another side adapted operatively to be engaged by the mold to support the mold from the casting frame and a lower portion in the form of a deflector spaced from the upper portion to define a channel therebetween which communicates with the openings through the casting frame and operates to carry the cooling liquid from the casting frame and to deflect the liquid onto the outer walls of the mold, and in which when the mold is of short dimension by comparison with the frame, the extender comprises a rectangularly shaped flat member in which the upper portion is formed with three side edge por tions with horizontally disposed flanges adapted to
