Definitions
- the present invention relates to a method for controlling the movement of a ladle according to the preamble of claim 1 and a casting machine for carrying out the method according to the preamble of claim 4
- a casting method has become known from EP-PS 592 365, in which the casting ladle after the first dessing process, while maintaining a certain safety distance between the pan body and the molding box, with the aid of a stationary tilting axis, can be moved further towards the center of the mold.
- the fixed tilting axis with the lifting drive is attached to the front of the pouring spout, and since the tilting bearing required on the tilting axis must also be at a safety distance above the molding box or the weighting iron, this also leads to a high pouring height in terms of design.
- a high pouring height entails significant disadvantages: since more kinetic energy has to be destroyed, a deeper pouring funnel is necessary so that the top box is not optimally used.
- the invention now has as its object to avoid all the disadvantages mentioned and to provide a method and a casting machine for controlling the movement of a ladle, with which it is always possible to pour with a low pouring height, even if the pouring funnels are arranged at any point in the molding box and at which the theoretical snout pivot point is constantly brought into the lowest possible position.
- This object is now achieved by the method and the casting machine, which have the characterizing features of patent claims 1 and 4.
- Advantageous embodiments of the subject matter of the invention are listed in the dependent claims 2, 3 and 5 to 9.
- FIG. 1 is a plan view of the casting machine shown in FIG. 1,
- Fig. 3 is a view of the ladle in the pouring position
- Fig. 4 sketchy a detail of the ladle suspension.
- the casting machine 1 on wheels 2 of a longitudinal carriage 3 on rails 4 can be moved horizontally in the Y direction parallel to a casting mold path indicated by 5.
- the longitudinal carriage 3 carries a transverse carriage 6 which can be displaced in the X direction by means of rail guides 7 transversely to that by means of a friction motor 8.
- a holding device 13 for the ladle 14 is arranged such that it can be raised and lowered in the vertical direction Z.
- the holding device 13 is suspended from chains 15, which is displaced via chain wheels 17 driven by a lifting motor 16.
- the tilting shaft 18 pivots a projecting suspension plate 20, in which the ladle 14 is fastened so that it can be suspended.
- the longitudinal carriage 3 with the casting ladle 14 filled with molten metal is moved in the Y direction until the pouring spout 21 at the level of the pouring funnel 22 is opposed to the casting mold 24 loaded with weighting iron 23, which is due to the electronic Control device 11 is effected.
- the electronic control device 11 has previously been programmed in accordance with the dimensions of the casting molds to be cast. According to this program to be called up, the friction motor 8, the lifting motor 16 and the tilt motor 19 are now controlled in such a way that the theoretical snout pivot point D with the radius R of the snout stone 25 moves from top to bottom on the curve K1, which is always the case while maintaining a safety distance corresponds to the lowest possible pouring height.
- the point of application K of the tilting moment on the curve K2 transmitted by the tilting shaft 18 via the suspension plate 20 to the pouring ladle 14 must move accordingly from bottom to top, which is done by correspondingly controlling the motors mentioned.
- the casting process can be automatically stopped by the control device 11 depending on the cast melt weight and can be resumed in the following mold.
- the electronic control device is programmed so that the lifting and lowering of the pouring spout is carried out at high speed during the pouring pause, which is to be kept as short as possible.
- several molds can be filled until the curves K1 and K2 are run through and the ladle is thus emptied.
- the casting machine has to drive to a loading and unloading station, where the empty ladle is replaced by a full one. After this, the casting process can be resumed after the drive back.
- two casting machines can be arranged next to one another, so that if the casting ladle of the first casting machine is empty, the second one continues the casting process immediately, while the first replaces the empty casting ladle with a full one.
- This method is that the loading and unloading station can be reached in both directions of the rails 4.
- the ladle 14 lies on the bottom with a rounded projection 31 on a projecting part 32 of the suspension plate 20.
- This pouring ladle suspension has numerous advantages: the casting machine can be made smaller, the accessibility between the pouring ladle and the casting mold is improved, only a vertical drive in the Z direction and a tilting drive around the axis A are required, and a rotating drive is required for changing the ladle enables this to be greatly accelerated and pans of different sizes can be used.
- the snout 21 of the ladle 14 is equipped with an interchangeable snout stone 25.
- the stone can be kept smaller and cheaper, it can be replaced quickly and easily when changing pans, and refractory material is saved.
- the exact insertion of the snout stone is effected by a holder attached in the snout, so that the radius R of the snout stone moves exactly around the theoretical snout pivot point D, which prevents a pouring jet migration during the entire tipping process.
- a specially shaped slag stone 33 is used in the vicinity of the snout 21 to hold back the slag, to break the waves and to destroy the kinetic energy generated in the pan by the tipping.
