"Device for receiving and adjusting electromagnetic Stirring devices in continuous casting plants "

The invention relates to a device for receiving and adjusting electromagnetic stirring devices in continuous casting plants.

It is known that electromagnetic stirring devices are used in continuous casting with the aim of being in the liquid strand sump to produce a movement. This measure is intended to improve heat dissipation with less directional solidification can be achieved with the formation of a globular structure of the crystals. As a result, there will be less segregation of the Accompanying elements and a reduced porosity of the strand core are expected.

Are known to be arranged on one side of the strand or around the strand

speaking stops (centering device) are made.

A major advantage of the device according to the invention, is also due to the fact that all parts of the actual stirring device are easily serviced and, if necessary, even can be changed during casting.

In the accompanying drawings are possible embodiments for a device according to the invention shown schematically.

Show it:

1 shows the possible adjustment and adjustment directions for the holding device carrying the stirring apparatus on Example of a square strand,

2 shows a holding frame that can be moved on mounting rails in a side view with receiving elements protruding into the strand area

3 shows a plan view of a device which can be moved transversely to the strand axis and has a common adjustment for a multi-part stirring device.

In Fig. 1, the individual adjustment and adjustment options are shown in several representations. The one on the holding frame 4 fixed adjustable and centerable mounting elements 3 carry electromagnetic stirring devices 2, which are placed on the jet cross section 1.

In the illustration shown in FIG. 2, the holding frame 4 added by mounting rails 5 and can be moved on these rails in the direction of the strand area. The receiving elements 3 or the holding frame 4 can be provided with a mix of guide rollers 6. On the holding frame 4 are on the stirrer

direction opposite side electrical and cooling devices 7 arranged. If necessary, counterweights can also be used there to be appropriate.

The illustration in FIG. 3 shows the stirring devices 2 around the square strand 1, which are attached to the receiving elements 3 ″ and which are mounted on mounting rails 5 via the holding frame 4 moved into the strand area and placed on the strand surface with the aid of known devices 9 (e.g. hydraulic cylinders) will.

The device according to the invention is with regard to all movement, guidance and cooling devices by non-conductive Material isolated from the rest of the continuous casting plant. For example, the support rails 5 (Fig. 2) or the rollers 8 of the Holding frame 4 made of non-conductive material.
