Definitions

  • Such a casting device is known from the US 4316561 A known.
  • shadow tubes are almost always used in the prior art.
  • the liquid metal is protected during encapsulation of the casting vessel - usually a ladle - in the distributor (tundish) or other vessel from environmental influences, so that the chemical composition of the liquid metal does not change during encapsulation.
  • the shadow tube is pressed by means of manual, electrical or hydraulic manipulators permanently to the underside of the pan closure. This results in a connection between the movable ladle and the stationary part of the caster during casting.
  • connection is not critical, since it can be solved again at any time.
  • the shade tube glued to the casting vessel. in the If sticking, immediate removal of the shadow tube from the ladle is not possible. If such a sticking occurs in the regular casting operation, this leads to a casting break, since the pouring vessel from the place where it is located, can not be moved away. It is even more critical if, in an emergency situation, a movement of the casting vessel is required. If sticking occurs in such an emergency situation, the manipulator impedes the movement away from the casting vessel. In extreme cases, this can lead to the liquid metal flowing onto the casting platform of the casting plant and destroying it.
  • the object of the present invention is to develop a casting device of the type mentioned in such a way that the above-mentioned problems are solved in a simple and cost-effective manner.
  • a manipulator for example, an industrial robot - only for attaching the shadow tube to the pan closure and for later removal of the shadow tube from the pan closure is in the path of movement of the casting vessel. Even if there should be sticking of the shadow tube on the ladle closure in the casting operation, this is therefore not critical, since the shadow tube is not held by the manipulator, but is attached directly to the pan closure. A movement of the casting vessel is therefore possible in this case.
  • the counter-holding device can be connected directly to the shadow tube when changing the shadow tube. The counter holding device therefore does not have to be present multiple times and in each case be connected in advance to one of the shadow tubes, but only has to be present once.
  • the shadow tube must be able to withstand contact with the liquid metal. It therefore consists - as in the prior art - of a refractory material. Such materials are usually brittle.
  • the holding device and the counter holding device do not come into contact with the liquid metal. They can therefore consist of a different material. In most cases, the holding device and the counter-holding device made of metal. As a metal, in particular steel comes into question.
  • the lateral recess is present only in a lower region of the counter-holding device, ie the counter-holding device is annularly closed in an upper region facing the ladle closure.
  • the lateral recess is formed as viewed continuously in the direction of the vertical axis, so that the counter-holding device seen in a plane orthogonal to the vertical axis seen a C-shaped cross-section.
  • the counter-holding device has an annularly closed cross-section.
  • the shadow tube has a central region in which the shadow tube, viewed in the plane orthogonal to the vertical axis, has a minimum diameter.
  • the shadow tube usually widens in the direction of the vertical axis towards the underside of the pan closure.
  • the expansion can in particular be conical.
  • the lateral recess is dimensioned such that the shadow tube is only laterally inserted into the counter-holding device when the counter-holding device is located in the central region of the shadow tube, as viewed in the direction of the vertical axis.
  • the counter-holding device is thus initially guided for receiving the shadow tube in the central region of the shadow tube laterally over the shadow tube, so that the counter-holding device engages around the shadow tube like a fork. Then, the counter-holding device in the direction of the upper, in the attached state adjacent to the socket closure end of the shadow tube is guided until the counter-holding device engages the shade tube.
  • the shadow tube preferably has a collar on its outer end facing the ladle closure on the outside.
  • the counter-holding device based on the vertical axis, a radially inwardly projecting C-shaped support web on which the collar of the shadow tube rests after the lateral insertion into the counter-holding device.
  • connection of the shadow tube with the pan closure can thus be designed in the manner of a bayonet closure. This type of connection is particularly easy to implement and works very reliable.
  • the number of shots and the corresponding number of holding elements can be determined as needed.
  • the number of L-shaped receptacles is exactly two and the L-shaped receptacles, relative to the vertical axis, arranged offset by 180 ° from each other.
  • the recordings have guide slots on which abut the holding elements of the holding device during rotation about the angle of rotation.
  • the guide slots run out horizontally or with a negative slope.
  • the counter-holding device preferably has an engagement device for attaching an assembly tool to the counter-holding device.
  • the counter-holding device can be easily connected by means of a manipulator with the holding device and released from it.
  • the ladle closure preferably has, in the region of the outlet opening, an attachment tip serving to guide the liquid metal, which protrudes into the upper end of the shadow tube. This achieves or improves a stable, tight seal between the shadow tube and the pan closure.
  • the shadow tube has a widening on its upper end facing the ladle closure.
  • the attachment tip protrudes into the expansion.
  • liquid metal 1 - for example, liquid steel 1 - from a casting vessel 2 in another vessel 3 - for example, a tundish - are poured.
  • a casting device has a ladle closure 4.
  • the ladle closure 4 is arranged on the underside 5 of the pouring vessel 2.

  • the shadow tube 11 is preferably not manually, but fixed by means of the manipulator 14 on the underside 6 of the pan closure 4 and released from the bottom 6 of the pan closure 4.
  • the manipulator 14 may be formed, for example, as an industrial robot. Regardless of its concrete design, however, the manipulator 14 according to the 3 and 4 an assembly tool 18.
  • the counter-holding device 10 has an engagement device 19, to which the assembly tool 18 can be attached.
  • the attacking device 19 may be formed, for example, as an arrangement of two surfaces, which are either parallel and have a guide in an initial area or slightly tapered at a small angle. The angle can for example be between 2 ° and 10 °.
  • the pan closure 4 has according to FIG. 2 usually in the region of the outlet opening 7, an attachment tip 21.
  • the attachment tip 21 serves to guide the liquid metal 1 out of the casting vessel 2 into the shadow tube 11.
  • the attachment tip 21 protrudes into the upper end of the shadow tube 11.
  • the shadow tube 11 has a widening 22 at its upper end facing the socket closure 4.
  • the attachment tip 21 protrudes as shown in FIG FIG. 2 into the widening 22.
  • the shadow tube 11 is, as already mentioned, made of refractory material. It is therefore relatively brittle and breaks easily. The shadow tube 11 should therefore be kept as free as possible of mechanical stresses in the counter-holding device 10.
