    1517887 Magnetic stirring CEM-COMPAGNIE ELECTRO-MECANIQUE 9 June 1977 [14 June 1976] 24232/77 Heading B1C An electro-magnet 3 for the centrifuging the molten metal in a continuous casting mould 1 comprises an annular magnetic armature situated in an annular tank 2 adapted to receive circulating water for cooling the casting mould which it encircles. The field windings are energised from a three-phase A.C. supply and the armature is formed to define six wide teeth 6 A to F constituting salient peripheral poles and the field windings are provided by six prefabricated polar coils 12u, v, w and 13u, v, and w, each mounted around a respective tooth 6 of the armature. Two of the coils are connected to each phase of the supply with the two coils of each phase being mounted on two opposite armature teeth and connected so that their magnetic fluxes are added together when energised. One of the two coils 12 of each phase is placed at the bottom of two slots one on either side of the respective tooth encircled by the coil and between it and the next adjacent tooth whilst the other coil 13 is placed at the top of the two slots contiguous to the opposite tooth, the coils of different phases partially overlapping one another in each slot.

    The invention relates to metallurgy, namely to the continuous casting of metals and alloys.
    A device for mixing molten metal in a crystallizer is known, which contains a mold with a sleeve and a water-cooled body and a three-phase current inductor made in the form of a core with six teeth and windings [1]. 10
    The disadvantages of this device are the short service life and low reliability due to the fact that the inductor is not protected from the effects of cast metal. fifteen
    The purpose of the invention is to increase the service life of the device.
    The goal is achieved in that the inductor winding placed in a water-cooled mold body, wherein the two windings of each phase are made with different radii and partially overlap one another and the inductor is provided with the reflecting-rings 25 telyami made of metal with a high conductivity and disposed between the outer wall mold housing and inductor windings. :
    In FIG. 1 shows a device, a General view in section; in FIG. 2 same view from above; in FIG. 3 - the nature of the magnetic field generated by the inductor.
    A device for mixing molten metal consists of a mold containing a sleeve 1 and a water-cooled housing 2. A three-phase current inductor 3 is placed in a water-cooled housing 2. The inductor 3 is made in the form of a core 4 with six teeth 5 and six windings 6. Windings 6 are placed around the teeth 5, have different radii and partially overlap each other. Inductor 3. It is separated from the sleeve 1 by means of a pipe 7 made of a non-magnetic material with a high resistivity, preferably stainless steel. To reflect the magnetic field to the center of the mold, reflector rings 8. Coolant enters the housing 2 and to the inductor 3 through the pipe 9, the annular box 10 and the holes 11.
    Windings 6 are made according to the pattern of copper wire with waterproof insulation, then they are wrapped!
    They are threaded with glass yarn and impregnated with thermosetting resin.
    This design and placement of the windings of the inductor allows you to create a powerful magnetic field (9000 A / cm 2 ) with minimal voltage consumption. .
    The magnetic field of the inductor (Fig. 3) is almost uniform over its entire internal space, and, therefore, the metal of the ingots is different. size will be mixed in the same way.

Such a constructive implementation and placement of the inductor windings allows creating a powerful magnetic field (9000 A / cm) with minimal voltage consumption. . The magnetic field of the inductor (Fig. 3 is almost uniform throughout its internal space, and therefore the metal of the ingots of various sizes will mix the same. Formula of the Invention A device for mixing molten metal into a crystallizer containing a mold with a sleeve and a water-cooled body made in the form of a core with six teeth and windings, characterized in that, in order to increase the service life of the device, the windings of the inductor are placed in a water-cooled There are two windings of each phase with different radii and partially overlap each other, and the inductor is equipped with reflecting rings made of metal with high conductivity and located between the outer wall of the housing of the crystallizer and the windings of the inductor. attention during examination 1.
