The invention is concerned with an apparatus for the intermittent continuous casting of metals a lowering table and a starting piece attached to it. She sets herself the task, the connection to make easily detachable between the lowering table and the cast strand after completion of the casting. It It is customary to provide the starting piece with a thread, a dovetail or the like in order to to connect the cast strand positively to the starting piece by placing the metal at the beginning of the casting is poured into the thread or the dovetail grooves. On the other hand is the starting piece detachably connected to the lowering table, for example by means of wedges or bayonet threads. It can after the casting including the strand are removed from the lowering table, whereupon the starting piece and the Strand still have to be specially separated from each other.

To connect a lowering device - in this particular case a lowering pipe - with a starter piece has also become known to be a hook-like latch, which is at the end of the lowering path is brought out of engagement with the starting piece by a stop.

The invention provides a significantly simplified connection between the strand and the lowering device achieved, which has the advantage of removing the finished cast strand from the Continuous caster to be easily detachable.

Namely, there is an apparatus for batch continuous casting of metals with a lowering table and a starting piece attached thereon with a driver for the strand is proposed in the case of the invention the driver can be detached from the strand by tilting the starting piece.

A suitable device of this type has a hook designed as a hook on the lowering table attached driver on which the starting piece is tiltably attached.

When casting metals or alloys in which the driving hook does not find a proper hold, A modification of the device is recommended, as a result of which one can be detached from the starting piece Intermediate piece with the strand form-fitting, z. B. is connected by thread.

Two exemplary embodiments of the device according to the invention are shown in the drawing. It shows

Device for intermittent continuous casting
of metals

Applicant:

Kreidler's metal and wire works G. mb H.,
Stuttgart-Zuffenhausen, Schwieberdinger Str. 9

Named as inventor:

Günter Ostermeyer,

Günther Radder, Kornwestheim (Württ.)

Fig. 3 is a section according to IH-HI of Fig. 1,

4 shows a second device in longitudinal section during the casting process,

Fig. 5 shows the same device also when removing the cast strand in section,

6 shows a section along V-V of FIG. 4.

In the embodiment according to FIGS. 1 to 3, a hook-shaped driver is on the lowering table 1 2 rigidly attached, protruding upwards, which has a nose 3 at its upper end. With the driver 2 and thus with the lowering table 1, the starting piece 4 is hinged and tiltable by bolts 5, namely, the starting piece 4 has a longitudinal slot 6 in order to receive the driver 2 therein. In its end face, the starting piece 4 has a tapered recess 7 into which the Nose 3 of the driver 2 protrudes.

At the beginning of the continuous casting, the metal fills the recess 7 and the cast strand 8 is during the lowering after the solidification of its lower section by the driver 2 with the Nose 3 held (see Fig. 1).

After completion of the casting, the strand 8 and the starting piece 4 are tilted a little. Included comes the nose 3 of the driver 2 out of engagement with the cast-on extension 8a of the strand 8 and this can easily be lifted upwards (see Fig. 2).

In the example of FIGS. 4 to 6, there is still an intermediate between strand 8 and starting piece 4

piece 9 switched on. This has a conical extension 10 with a recess 10a . It thus sits in a conical recess 11 of the starting piece 4, the nose 3 of the driver 2 engaging in the recess 10a. To connect to the

Cast strand 8, the intermediate piece 9 has a threaded hole 12, which at the beginning of the casting of the metal is filled out.

Here, too, the cast strand 8 with the starting piece 4 is tilted somewhat after the casting has ended. In this case, the nose 3 comes out of engagement with the extension 10 and the strand 8 can together with the intermediate piece 9 are lifted off. Then the intermediate piece 9 is unscrewed from the strand.

Claims (3)
