Definitions

  • the invention relates to a continuous casting machine in which the mold and the first section of the apron form a unit that can be removed from casting position.
  • the mold and the first section of the apron form a unit that can be removed from casting position.
  • it isdesirable to shorten the stoppages in the event of a change in casting cross-section, a quality change or operational trouble.
  • the upper section of the apron is combined with the mold table to form a structural unit which can be tilted about a stationary axis.
  • pins, bolts and water supply pipes must be undone to enable the mold table to be tiltably raised by the foundry crane.
  • the apron section can be exchanged for a prepared fresh unit. This exchange which must be performed with the aid of the crane takes some time to complete. Another drawback is that for undoing and.
  • a turntable mounted to rotate about a vertical axis, for the reception of two units, each comprising a mold and a first section of the apron, that can be optionally moved into alignment with the upper end of the rest of the apron.
  • a continuous casting machine has already been proposed in which at least a part of the roller apron directly following the mold is traversible across the casting axis so that it can be exchanged.
  • this is an arrangement that requires considerable space on both sides of the apron and the casting platform' must therefore be wider.
  • the units can be hingeably raised on the turntable.
  • this arrangement enables them to be as closely spaced as heretofore without mutual interference between the associated turntables when the units are being replaced.
  • the'oscillating drive which is mounted in a fixed position should be releasably connected to the mold.
  • This connection is releasable in the direction in which the mold is hingeably raisable. In other words, when the unit is raised or lowered the connection of the mold to the oscillating drive is automatically released and reestablished.
  • sections carrying a track may be located in recesses in the hinged part of the turntable, thereby extending the track provided on the casting platform for the tundish carriages across the turntable.
  • a section carrying the bearings of the turntable is mounted on trunnions extending parallel to the axis of curvature of the apron and connected to a frame supporting the continuation of the apron.
  • FIG. 1 is a plan view of a turntable carrying two molds.
  • FIG. 2 is a side elevation of the turntable.
  • FIG. 3 is a section taken on the line III --.-III in FIG. 1, and
  • FIG. 4 is a schematic representation of the disposition of two continuous casting machines equipped with turntables.
  • a box section 2 Pivotably mounted on trunnions 3 on the supporting framework 1 of a continuous casting machine is a box section 2. Attached to the box section 2 is a frame 4 which carries sections 5 of a roller apron. Likewise secured to the box section'2 is a platform 6 which carries a circular track 7. The ring mount 8 of a turntable 9 runs in this track 7 on balls. The ring mount 8'has inter.- nal gear teeth 10 engaged by a pinion 12 driven by a motor 11.
  • each arm 15, 16 is pivotably mounted on horizontal pivot pins 13, 14.
  • Each arm v15 16 is formed with a recessed socket 17, 18 for the reception of lateral trunnions 19 of a first guide zone 20.
  • the guiding elements in this first guidezone 20 are plates 2L and rollers 21.
  • Located above each of the first guide zone- 20 is a mold 23 resting in a U-shaped saddle 24.
  • brackets 25 which carry rollers 26 running between ledges 27 fitted to'the inside of the saddles 24.
  • Each saddle24 is suspended from two upper links 28 and two lower operating levers 29, 30 which are attached to a shaft31 mounted on the arms 15,163An extension 32 on each operating lever 29, 30 is. connected to the arm 15 respectively 16 through an inter
  • An eccentric 36 for oscillating the molds is driven by a motor 37 secured to the box section 2.
  • the eccentric 36 operates a pusher arm 38 which is linked to a transmission lever 39 mounted on the platform 6.
  • Fitted to the other end of the transmission lever 39 is a pin 40 which enters an open slot 41 in a lever 42 on shaft 31 when the unit is lowered. Connection to the operating lever 42 of the mold 23 is thus established.
  • self-closure valves 43 connected to the mold 23 by pipes not shown are mounted on the arms. Associated with the self-closing valves 43 are water supply and return pipes 44, 45 on the platform 6. These elements are automatically coupled when the arms 15, 16 are lowered into pouring position.
  • Sections 48 carrying rail tracks 47 are let into recesses 46 in the arms l5, 16. This arrangement extends a track 49 for tundish cars on the casting platform across the turntable 9.
  • a platform In a continuous casting machine in which the mold and the first section of the apron of the secondary cooling zone are connected together to form a unit, a platform, a turntable mounted thereon to rotate about a vertical axis to bring a selected unit to casting position, means to support two of said units on said turntable, said means being mounted to swing on parallel horizontal axes.
  • Apparatus as claimed inclaim 1 including means to oscillate one of said units when it is in casting position, said unit being detachably connected to said oscillating means.
  • said oscillating means comprises two interconnected levers, one of said levers having a slot therein and the other of said levers carrying a pin which engages said slot when said unit is in casting position, and disengages said slot when said unit swings away from casting position.
