Definitions

  • the present invention relates to a bar for use as a dummy bar in a continuous casting machine.
  • the invention provides a dummy bar made up of a plurality of sub-bars each having a spigot on one end and a recess in the other end, so that sub-bars can be interconnected in series with the spigot of one sub-bar engaging in the recess of the next sub-bar, in order to provide a dummy bar made up of a number of sub-­bars.
  • the invention provides a dummy bar comprising: a first sub-bar having at one end a recess, a second sub-bar having at one end a spigot for engaging the recess of the first sub-bar to interconnect the sub-bars and hydraulic means for urging the sub-bars to interconnect with one another.
  • the hydraulic means is the form of a hydraulic piston and cylinder assembly mounted within one of the sub-bars, and interconnectable with the other sub-bar in use.
  • a dummy bar is made up of series of sub-bars the ends of only two of which are shown.
  • the end of one sub-bar 1 has a spigot 2 with a notch 3.
  • a chamber 4 in which slides a piston 5 connected to a rod 6 which projects through the spigot 2 and at the end of the rod 6 is an eye 7.
  • a recess 11 In the end of the other sub-bar 10 is a recess 11 with a secondary recess 12 at the back of the recess 11.
  • Transversely through the sub-bar 10 extends a hole 13 which meets the sub-recess 12.
  • the hole 13 through the sub-recess 12 receives a pin 16, in use.
  • each sub-bar has at one end a spigot and associated piston cylinder assembly, and recesses with associated holes at its other end.
  • the two sub-bars can be separated by a reverse procedure involving removing the pin 16 and applying hydraulic pressure into the left hand side of the chamber 4 to move the piston and piston rod to the right as shown in ( Figure 2), thereby separating the two sub-bars from one another.
  • the hydraulic arrangement could be temporarily secured by means of bolts to the outside of the sub-bars to draw them together and once the sub-bars are secured by means of the grub screw engaging the notch in the spigot, the hydraulic mechanism could be removed from the interconnected sub-bars.
