Definitions

  • the device according to the present invention is characterized by drain traps (drain bags) having one is the danger that, for instance when a delivery nozzle SUMMARY OF THE INVENTION
  • the present invention relates to a continuous casting machine provided with a device which enables the operator to prevent the damages at the caterpillar mold and at the machine (before all at the supporting, the
  • drain traps are provided at least at one end with a lateral outlet for molten metal.
  • these drain traps must be made in such a way that their longitudinal edges may be repeatedly spread at least so far apart as the fixing spots at the front sides of the mold halves separate during the revolution of the said mold halves.
  • overflowing molten metal discharges for instance over deflectors into drain channels under the drain traps and from there into suitable collecting reservoirs.
  • the drain traps can be manufactured for instance from a refractory non-metallic textile fabric or from two metal sheets hinged together.
  • FIG.- 1 is a schematic side elevation of the half of the casting machine at the inlet end in a first embodiment of the invention, with omission of theparts which are not necessary for the understanding, this embodiment comprising drain traps made from asbestos cloth,
  • FIG. 2 shows the part A of FIG. 1 on a greater scale and FIG. 3 shows the part B of FIG. 1 on a greater scale;
  • FIG. 4 illustrates by means of an exploded view of a corner of a drain trap the securing method on the front side of a mold half and FIG. 5 the completed attachment according to FIG. 4;
  • FIG. 6 shows a section along the line C.C of FIG. 1 across the whole mold width (but only of the middle portion of the mold),
  • FIG. 7 is a perspective view of a'drain trap made from metal sheet according to a second-embodiment of the invention.
  • numeral 14 means the supporting frame of the casting machine, the numeral 15 the supporting structure for the hydraulic piston device 16 which supports the metal feeding trough 17 and enables to move the same in longitudinal direction.
  • The'numeral l8 denotes a support made from cast steel having a low coefficient of expansion for the nozzle 19 made of Marini te.
  • a drain trap 20 made of asbestos cloth of about 2 to 2.5 mm thickness is secured between the opposite frontsides of each pair of mold halves of the lower caterpillar chain 10.
  • asbestos cloth one may use for instance Fiberfrax (trade mark) textile fabric with or without chromenickel steel wire inserts.
  • the drain trap 20 extends over the whole mold width. It is suitably widened on both ends from the longitudinal edges by which it is secured to the mold halves to the fold and forms in this way two outlets 20 0.
  • the drain trap much wider than the mold halves, to close it at one end and to let the said end protrude, whereas an outlet is formed at the other end. With such an embodiment molten metal which possibly flows out would be collected only at one side of the casting machine.
  • the appertaining fastening ledge 21 as well as the flat springs 22 there is provided an offset 24 on the front side 23 of the mold halves 12 (FIG. 4) so that the opposite front sides 23 of each pair of mold halves can touch one another tightly without being hindered by the drain trap 20.
  • a screw bolt 25 (FIG. through the borehole 26 in the ledge 21, through the borehole 27 in the flat spring 22 and through the U-shaped recess 28 of the drain trap and screws the said screw bolt into the borehole 29 of the recessed portion of the mold half.
  • four flat springs 22 are fixed on each drain trap 20, two at both ends (FIG. 6).
  • the flat springs 22 serve the purpose of preventing the collapse of the drain trap 20 on the lower path of the caterpillar chain, when the mold halves are directed downwards. On the said lower path the drain trap 20 still extends straight into the space between the mold halves. In the absence of these flat springs the drain traps slip between the front sides 23 of the mold halves 12 on the lower travel path of the lower caterpillar chain, hinder the said front sides from touching one another and put the casting machine out of service.
  • the flat springs 22 are made for instance from a mm wide and from 0.5 mm to 1 mm thick strip of spring steel and have a length which does not reach the bottom edge of the mold half 12, but extend for instance at most on about two-thirds of the length of the asbestos cloth. Their free end is somewhat rolled in the direction of the opposite flat spring in order to prevent any damage to the asbestos cloth.
  • the cavity 30 of the mold (FIG. 6) is formed by the molding walls of the mold halves 12 and 13 and by both the lateral edges 31 screwed on the mold half 12.
  • the drain and connecting strips 48 In the second embodiment shown in FIG. 7 the drain and connecting strips 48.
  • the mold half to which the sheet 42 in the foreground is attached is not shown in the Figure.
  • the sheets 42 In the inside of the drain trap the sheets 42 are covered with a mold dressing, Fiberfrax-felt or the like, so that when molten metal flows out it does not freeze at once or not to a worth mentioning extent in the drain trap.
  • Machine with horizontally or inclined disposed caterpillar mold for the downward casting of non-ferrous metals, especially aluminum and aluminum alloys comprising drain traps between-the adjacent mold halves of the lower caterpillar chain, said drain traps having onelongitudinal edge secured to-the backv of one mold half and the other'longitudinal edge secured to the front of the subsequent mold half, the said drain traps being provided at least at one end with a lateral outlet for molten metal, and comprising furthermore flat springs which serve the purpose of preventing the collapse of the drain traps on the lower path of the caterpillar chain.
