Definitions

  • the invention relates to apparatus for casting molten substances, particularly for casting molten metals in the form of ingots.
  • the present invention provides a casting apparatus comprising a battery of molds which is carried upon and around the exterior of an endless horizontal conveyor, and means adapted to charge a quantity of the molten substance into each of the molds in succession, to spray the exteriors of the molds with a liquid coolant so as to cool the substance contained therein, and to strip the cooled substance from each of the molds also in succession.
  • the superstructure is provided with two horizontal, superimposed endless tracks 9, having semicircular ends; the lower track 9 is fixed upon the top of base frame 4 whereas the upper track 10, which is of inverted channel section, is fixed upon the underside and extends around but inwardly of the periphery of the top decking 8, and each of the semicircular ends of the lower track is concentric to, but of a larger radius than, the corresponding end of the upper track.
  • the shaft 12 extends through and beyond the underside of thebox structure and is adapted to be rotated intermittently in a sequence of equiangular steps by a double-acting hydraulic cylinder 19 which is carried by the base of the main frame and is adapted to rotate the shaft through a free wheel ratchet device comprising a ratchet wheel 20 fast upon the shaft portion projecting below the said box structure.
  • the hydraulic cylinder is adapted to be operated by fluid delivered from a motor-driven pump 21, which is also mounted upon the base of the main frame, under the control ofa timer (not shown) mounted on a control panel 22 carried by and between two of the stanchions 2.
  • the chains l7, 18 are component parts of an endless conveyor which also comprises a battery of identical carriages 23 and a battery of identical, boxlike mold holders 24, thecarriages being pitched equidistantly apart lengthwise of the conveyor and being located externally of the chains, and each of the mold holders being carried in a corresponding one of the carriages.
  • Each of the carriages 23 is of U-shape in cross section, the external surface of its flat rear wall 23a is anchored to both of the chains by swivel links or equivalent expedients, its sidewalls 23b are flat and parallel to one another, project away from the chains at right angles to the rear wall, and their lower edges and the lower portions of their front edges are spanned by a bottom wall 23c so as to form a well in the bottom of the carriage.
  • Each of the mold holders 24 has an open top which is surrounded by an external flange 29 and is closed by an opentopped mold 30 accommodated within the holder and having an external flange 31 which overhangs, coincides with, and is secured, by bolts or other means (not shown), to the flange 29; the mold dimensions are such that the whole of the external surfaces of its walls and floor are spaced, respectively, from the internal surfaces of the walls and floor of the holder.
  • the holder is provided with a pair of coaxial fulcrum pins 32 which, respectively, project from and at right angles to the sidewalls of the holder and are received and are rotatable in slots 33 formed in and opening to the upper edges of the carriage sidewalls, the said pins being located nearer to the holder end which is adjacent to the carriage wall 23a when the holder is horizontal, than to the opposite holder end so that the holder tends to turn from the horizontal to the vertical, about the common axis of the fulcrum pins, in the direction which causes the open top of the mold to face outwardly of the apparatus as shown, for example, at the left of FIG. 2.
  • a bracket 34 is secured upon the end of the flange 29 which is adjacent to the carriage wall 230 when the holder is horizontal, and a roller 35 is journaled upon the bracket about an axis parallel to the longitudinal centerline of the holder.
  • each of the said flexible pipes is connected to a corresponding one of four tubular spigots 42 projecting from, and spaced at equidistant intervals apart along the length of, an endless ring main 43 which is located above and inwardly of the perimeter of the top decking.
  • the ring main comprises a number of rigid tubes 43a which are located in a common horizontal plane and each of which is fixed within and projects beyond the opposite sides of a bracket 44 projecting rearwardly from the stepped, upper end of the rear wall 23a of a corresponding one of the carriages 23, and an equal number of flexible tubes 43b each of which is connected to the adjacent ends of a corresponding two of the rigid, bracket-supported tubes 43a.
  • each of every one of the said tubes is provided, as shown in FIGS. 1 and 2, with a rigid outlet tube 45 which is connected, by a flexible pipe 46, to a tubular union 47 secured in the underside of the mold holder pivoted upon the same carriage as that on which the bracket-supported tube is carried, and communicating with a duct housed within the holder and provided with the nozzles referred to above.
  • Each of the mold holders is provided with two water discharge outlets, namely (see H6. 3) an uncontrolled outlet 48 and a valve-controlled outlet 49, each having a flow capacity sufficient to prevent the water which is sprayed on to the mold by the nozzles, from accumulating within the holder to a depth sufficient to submerge any of the nozzles.
  • the uncontrolled outlet is provided in the underside of the holder end which is adjacent to the carriage wall 230 when the holder is horizontal and is uppermost when the holder is vertical, so that the said outlet is adapted to discharge water into the well formed by the bottom wall 23c, only when the holder is horizontal.
  • each of the holders for spraying a liquid coolant on to the external surfaces of the charged mold depending into and closing the open top of the holder so as to cool the molten substance charged into this mold, at least one outlet in each of the holders for discharging the sprayed liquid from the latter, and means for stripping the cooled substance from each of the molds in succession.
  • each mold holder is so pivoted in the corresponding carriage that it tends to turn from the horizontal to the vertical, and means are provided whereby, as the carriage is conveyed from a pouring sta' tion where a quantity of the molten substance is charged into the mold in the holder, the latter is retained in the horizontal during a first predetermined fraction of the carriage travel, is then allowed to turn to the vertical to strip' the cooled substance from the mold and to remain in the vertical during a second predetermined fraction of the carriage travel, and is returned to the horizontal before the carriage returns to the pouring station.
