Abstract:
The invention relates to a method and device for continuously casting metals (1), especially steel, in a cooled oscillating continuous casting mold (4), in which the crater is subjected to a treatment by an electromagnetic stirring coil (9), whereby the magnetic field is placed in close proximity to the cast strand (8) underneath the continuous casting mold (4). The aim of the invention is to adjust the effects of the stirring coil not only outside but also during the casting process. To this end, the invention provides that with a stationary stirring coil (9), which follows the continuous casting mold (4) in a direction of movement (14) of the strand, a continuous relative change in position of the magnetic field of the stirring coil (9) is effected in the direction of the casting vein by adjusting the oscillation area of the continuous casting mold (4) according to the casting parameters.
Abstract:
A device for the continuous casting of metals, especially steel material, to elongated products in a multistrand casting apparatus with a plurality of continuous casting molds which are oscillatingly driven in an oscillating frame (2) by means of leaf springs (4) whereby the leaf springs (4) extend transversely to the casting direction (1) and serve for guide and weight compensation. The smallest possible strand spacing "A" is provided for that on a longitudinal foundation frame (5) to housings (6a) in the form of compact flat cassettes (6) are secured one behind the other in the strand travel direction. In the housings upper and lower leaf spring pairs (4a; 4b) run transversely to the cast strands (3) and the oscillating strands (11) engage the leaf spring pairs (4a; 4b), whereby a front oscillating drive (11a) works synchronously with the rear oscillating drive (11b).
Abstract:
The invention relates to a device for supporting and oscillating a continuous casting mold (1) for continuously casting molten metals, particularly molten metal materials, comprising: guide elements (4) symmetrically arranged on both sides of the central longitudinal axis (2) of the casting; fixed supporting parts (5), and; a continuous casting mold (1) supported on paired oscillating devices (6). The inventive device facilitates the accessibility to individual modules for maintaining and/or eliminating damages. To this end, a module (7) that, itself, can be removed, is formed from paired bearing blocks (9) with guide elements (4) and with a supporting casing (7a) connected to said bearing blocks. The module is placed upon a stationary submodule (7b) and detachably connected thereto.

Abstract:
Four pressure cylinders serve as adjustment units located outside the heat radiation zone above the slab guide segment. Four pressure cylinders (4, 4', 5, 5') serve as adjustment units are located outside the heat radiation zone above the slab guide segment. The distance (A) between the pressure cylinders determining the segment width is reduced. The segment cross members are provided with plates for protection against heat radiation. Water-cooled side frames (11) are attached laterally to the bottom frame (8).
Abstract:
Process for the continuous casting of metals, especially steel comprises treating the casting sump using an electromagnetic field; and changing the relative position of the magnetic field of a stirring coil in the direction of the casting strand by adjusting the oscillating region depending on the casting parameters. An Independent claim is also included for a device for the continuous casting of metals, especially steel. Preferred Features: The device for producing oscillations is operated using an extended adjusted region. The zero position of the oscillation is shifted opposite the magnetic field of the stirring coil. The extended adjusted region is extended depending on the type of oscillation device.
