Definitions

  • Patented Aug. 11, 1970 3 523 573 purities present in the liquid, ultimately resulting in col- CONTINUOUS VERTICAL CASTING APPARATUS lapswfthesheet- WITH IMPROVED COOLING Serge Peyraud and Jean Freiche, Issoire, France, assignors to Cegedur GP, Paris, France Filed June 21, 1968, Ser. No. 739,031 Claims priority, application France, June 29, 1967,
  • This invention relates to an apparatus for continuous vertical casting and more particularly to an apparatus of the type described having an improved cooling system.
  • slabs or billets can be made by vertically casting a molten material, such as a metal or an alloy, into a mold with vertical generatrices having internally the section of the product to be cast.
  • the mold is cooled to enable the material to solidify.
  • cooling is obtained by allowing a liquid, such as water, to flow down the outer wall of the mold.
  • the mold is surrounded at its upper end by a chamber, known as a casting frame, provided with one or more openings through which the cooling liquid flows.
  • the mold is usually supported by means of a flange on the upper part of the casting frame, the flange being machined in a manner to keep the mold properly centered.
  • 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.
  • the casting frame is formed with a row of horizontal or inclined passages through which a liquid, such as water, flows and cools the outer surfaces of the mold. Occasionally, use is made of an inclined continuous slot instead of such openings.
  • the slot system has the disadvantage of being extremely expensive by reason of difficulties involved in machining.
  • the slot has to be extremely narrow with the result that there is danger of frequent partial blockage from im-
  • the two systems comprising inclined holes or an inclined slot further share the common disadvantage of sprinkling the mold from a section situated too far from its head thus making it necessary to make use of much taller molds.
  • FIG. 1 is a sectional elevational view of a portion of the apparatus embodying the features of this invention
  • FIG. 2 is a perspective view showing the elements in their relative positions
  • FIG. 3 is a sectional elevational view of a modification in the form of a twin frame apparatus adapted for use with molds of lesser cross-section.
  • the apparatus embodying the features of this invention comprises in combination a casting frame with holes drilled perpendicularly through its side Wall, with the holes being situated at the bottom of a groove the width of which is equal to the diameter of the holes; at least one vertical mold of conventional construction and, in the space between these two components, at least one unit in the form of a mold supporting frame operatively engaged at one end to the casting frame and at the other end to the mold, and a deflector provided on its upper face with channels substantially parallel to the axis of the nearby holes and situated beneath the frame so as to form a duct therebetween through which the cooling liquid flows for transmission onto the mold.
  • the apparatus additionally includes at least one of the following features, namely:
  • the mold supporting frame rests on the casting frame through a flange which insures proper centering
  • the mold supporting frame Adjacent the mold, the mold supporting frame comprises a retaining means which receives a flange integral with the mold;
  • the deflector is held to the mold supporting frame by means which enables adjustment of height of the duct that is formed between the deflector and the supporting frame and through which the cooling liquid flows;
  • the deflector Adjacent the mold, the deflector has a smooth ledge terminating in a draft edge to insure the formation of a. sheet of cooling liquid.
  • the continuous vertical casting apparatus with its improved cooling system comprises a casting frame 1, a mold 2 having its outer wall spaced from the casting frame, and an intermediate element comprising a mold supporting frame 3 and a deflector 4.
  • the casting frame is provided with a continuous horizontal groove 12 at the bottom of which are drilled holes 13 having a horizontal axis and the diameter of which is equal to the width of the groove.
  • the groove 12 makes it easier for the holes 13 to be drilled and aligned and it operates to join the streams of water in the event that one of the holes becomes blocked.
  • the holes the function of which is not to form a sheet of water but solely to insure that the intermediate unit is regularly supplied with water or other cooling liquid, are relatively large in diameter.
  • the mold 2 with its vertical axis 21 is of conventional design. It is formed with an upper horizontally disposed outwardly extending peripheral flange 23 which, in conventional apparatus, is adapted to rest directly upon the upper part of the casting frame 1.
  • the mold supporting frame 3 is engaged at one end to be casting frame 1 and at the other end to the mold 2.
  • it comprises, adjacent the casting frame, a horizontally disposed edge flange 32 adapted to rest on the upper face of the casting frame 1 and, adjacent the mold, an inner retaining means or recess 31 which is adapted to receive the flange 23 of the mold.
  • the deflector 4 On at least part of its upper face, the deflector 4 is provided with channels 41 which extend substantially parallel to the axis of the next hole 13. Adjacent the mold, the upper surface of the deflector terminates in a draft edge 42 which may be preceded by a smooth, horizontally disposed ledge 43.
  • the channels stabilize the flow of liquid in the transverse direction through the duct from the holes of the casting frame to the draft edge 42 and prevent the sheet of liquid from shifting to one side.
  • the smooth ledge portion enables the sheet of water to spread out while the draft edge enables a sheet of liquid to be formed for deflection onto the outer wall of the mold for cooling the mold forming section situated at a level 22 adjacent its upper end.
  • the deflector is attached to the supporting frame by means of studs 44 and bolts 45.
  • the external upper portion of the mold is shaped to be rectangular or square in section with the casting frame itself being of rectangular shape.
  • the frame is thus in one piece while the deflector may consist of four elements attached to the frame.
  • An apparatus for continuous vertical casting having a vertical mold and a casting frame with a spaced relationship therebetween, the improvement in a system for cooling the mold by deflection of a stream of cooling liquid onto the outer wall of the mold comprising a groove in the side wall of the casting frame and openings extending perpendicularly through the wall of the casting frame contiguous with the groove and having a diameter equal to the width of the groove, and at least one mold supporting frame interconnecting the casting frame with the mold and a deflector extending crosswise between the casting frame and mold and in spaced relation with the mold supporting frame, the upper face of said deflector being formed with channels extending substantially parallel to the axis of the adjacent openings in the supporting frame and located beneath the openings to provide troughs over which the cooling liquid flows from the openings across the deflector for projection onto the mold.
  • An apparatus as claimed in claim 1 which includes a horizontally disposed edge flange on the mold supporting frame which rests on the casting frame for proper centering of the mold.
  • An apparatus as claimed in claim 1 which includes a recess on the end portion of the mold supporting frame adjacent the mold and a peripheral flange on the mold which rests in said recess.
  • An apparatus as claimed in claim 1 which includes means for securing the deflector onto the mold supporting frame and which includes means for varying the space between said frame and deflector.
  • An apparatus as claimed in claim 1 which includes a smooth horizontally disposed ledge on the edge portion of the deflector adjacent the mold for spreading the cooling liquid flowing over the deflector to the mold.
