Definitions

  • the object of this invention is a vibrating die system with built-in cooling device for continuous vertical casting apparatus.
  • vibrating die systems with built-in cooling devices for continuous casting apparatus are well known. Background ⁇ n
  • the dies in the continuous vertical casting apparatus besides having a cooling device for cooling the melt. J metal that slowly descends within it from the pot furnace outlet (metal crucible), are subjected to axial vibrations (oscillations) in order to favour in a controlled manner the progressive descent of the metal.
  • These vibrations: - are generally mechanically impressed to the die and therefore there is a notable construct.
  • I 0 device by means of an external guide and support jacket and through
  • I I a fluid dynamic coaxial cylinder acting as a piston placed between i ' . said die/s system with said cooling device and said external guide and 1 3 support jacket that acts as a distributor.
  • the die system includes more than one die. 0 In this way an increase in productivity is reached. 1
  • the entry and exit of the cooling are made by 2 passage through said fluid-dynamic piston cylinder. 3 In this way a maximum compacting of the plant is obtained. 4
  • the dies have a built-in cooling system. 5 In this way the advantage to simplify the construction system

  • Die/s 2 is/are extractable and interchangeable from below and around the same there is a coaxial cooling jacket 3.3A, which inlets and outlets of liquid occur by means of two ducts 31 and 32 that pass through a coaxial fluid dynamic piston cylinder 4 that moves axially backwards and forwards in a reciprocable way, by distributor of known art 41-42 in an external cylindric coaxial support and guide jacket 5.
  • Introducing oil into the distributor 41-42 according to known art an alternating oscillation movement of the entire die system/group will be obtained, making the cast descend in cooling progression in the exit direction indicated by the arrow with a "u".
