Definitions

  • pan valves For pouring liquid metal - for example steel - casting vessels are usually used, which have on their underside an opening mechanism. Often, so-called pan valves are used for this purpose.
  • a pan pusher is a device that can be attached to the bottom of the pouring vessel and has two plates. The two plates each have a passage opening and are mutually displaceable. By appropriate displacement of the plates against each other, the two passage openings can be made to coincide with each other. In this position, the pan slider is open, so that the liquid metal can escape from the casting vessel. If, starting from this open position, one of the plates is displaced against the other plate or both plates, starting from this open position, shifted against each other, thereby the pan slide can be closed.
  • the displacement of the plates against each other is usually carried out by means of a hydraulic cylinder unit, in the art as Pan slide cylinder called.

  • the pan slide cylinder more precisely: the cylinder of the hydraulic cylinder unit - connected to the pan slider.
  • the piston of the hydraulic cylinder unit is extended.
  • the piston On its front side, the piston has a coupling device, which automatically couples with the extension of the piston with an actuator for the pan cylinder, so that the actuator follows both the extension of the piston and the retraction of the piston of the movement of the piston. From the coupling of the pan slider is thus ready for use.
  • the ladle and / or the pouring vessel in general can now be hydraulically opened and closed as required.
  • the insertion of the flange-like fastening device in the drive lantern is done manually by the operating staff of the caster.
  • the flange-like fastening device can thereby be inserted without play or almost free of play in the drive lantern of the pan slide and then secured by means of a hand bolt against falling out. Due to the freedom from play, the opening position of the pan slide and thus the flow of liquid metal through the opening of the pan slider can be controlled exactly.
  • an automated production of the connection between the pan slide cylinder and the pan slide is not possible with the pan slide and the pan slide cylinder of the prior art.
