    A process and apparatus for casting a material into a desired thin strip shape. Molten material is formed into the thin strip shape by an electromagnetic containing and forming process. In a first portion the molten material is shaped into the desired thin strip shape and in a second portion upstream of and communicating with the first portion the molten material is electromagnetically contained in a sump. The sump at a top surface thereof has a substantially larger cross-sectional area as compared to a cross-sectional area of the thin strip shape.

    3. The device according to paragraphs. 1 and 2, I distinguish it by the fact that it is equipped with means for supplying solid material and controlling the rate of its entry into the inductor
    4. The device according to claim 3, wherein the means for feeding solid material and controlling the speed of its entry into the inductor are made in the form of driving rollers mounted above the inductor.
    5. Device on PP. 1 and 2, characterized in that it is provided with a means for rolling the strip into a coil.
    This invention relates to metallurgy, in particular to continuous melting of metals and alloys.
    The aim of the invention is to improve the quality of the strip by improving the homogeneity of the structure.
    Figure 1 presents the device in the first embodiment, a General view; figure 2 - the device according to the second variant, general view; in FIG. 3 a means for coiling the strip into a coil.
    The device for electromagnetic casting of the strip (Fig. 1) comprises an inductor 1, water cooled, an electromagnetic screen 2, a cooling system of the strip 3, made in the form of a collector 4, a source of gasing 5 of the inductor 1, a control system 6 with the engine 7 connected to gear 8 interacting with the rack element 9 of the valve 10 of the pouring funnel 11 having a drain connection 12. The device also contains a pulling mechanism 13 with a seed 14. The inductor 1 is supplied with alternating current from the power source 5 and the control system 6, and the current in the inductor is controlled so as to maintain the inductance of the inductor at a constant level and the same air gap 15 between the molten metal 16 to the inductor 1 during the entire npoi.ecca cast. Inductor 1 has an unequal cross-section in height, namely: the upper part A of the inductor is made with the expansion upwards, and the lower part B of the inductor has a rectangular shape,
    those. the shape of the cast strip, with the maximum cross-sectional area of the inductor cavity in the upper part of D at least five times (preferably seven
    fold) it exceeds the cross-sectional area at the bottom of B. This device is designed to cast thin strips of metals and alloys with a thickness of up to 18 mm (preferably up to 12 mm).
    In the second embodiment (Fig. 2), the device for electromagnetic casting is intended to produce castings in the form of ultrathin strips.
    with a single crystal structure of metals, alloys, and metalloids, including semiconductor materials, such as silicon, etc. The device is located inside the chamber 17, in which there is an inert gas, such as argon, to maintain the purity of the cast material. Inductor 1, (FIG. 2) has the same configuration as the inductor in FIG. 1, but is made of two separate parts C and C, electrically isolated from each other using insulating pads 18. Each part of inductor 1 has independent power sources 19 and 20 independent control systems 21 and 22. The current supplied to the upper part p of the inductor must not only maintain the molten material bath, but also heat the material to a temperature at which it will melt the solid material 23 supplied by the driving rollers 2A rasp decomposition of the inductor 1. The drive rollers 24 are means for feeding solid material and adjusting the speed was received by laziness inductor. The thrusting mechanism is similar to the sticking mechanism in the first embodiment (Fig. 1), but a single-crystal seed is used to produce a single crystal. Fig. 3 shows another embodiment of the stitching mechanism 13. It consists of a seed element 74 of ment 25, a drum 26 and feed rollers 27 and is intended to cast longer and thinner strips that are lubricated into the coil. The device for electromagnetic casting strip works as follows. Molten or solid material is fed to inductor 1, the upper part of which is a collection of molten material, and a strip is formed in the lower part. The forming strip is cooled either directly in the inductor or after exiting it. The strip is stretched by means of a pulling mechanism 13. The stretched strip can wind into a coil or go to rolling. With the help of power sources and control systems, they maintain the required power of the inductor, provide the necessary material feed rate and control the required level and hydrostatic pressure in the inductor. The proposed device allows casting strips with a high quality monolithic structure.
