The proposed invention relates to the field of foundry work and may be used for casting, reducing and purifying of any metals, including refractory and chemically active metals. The claimed induction melting method and device for the implementation thereof combines loading a charge 2 into a mold 1, having a beveled top surface. Above the mold 1 there is mounted with clearance therefrom an inductor 3, having a beveled bottom surface. The charge is heated by a magnetic field 6, and additional sources of heat can be used. The top surface of the mold 1 is beveled parallel to the bottom surface of the inductor 3, thus forming an inclined slot 13, which permits a stream 8 of the melt to pass through an overflow element 4 into the ingot mold 9. The charge 2 is held in the mold 1 by a movable base in the form of a piston 5, which moves the charge into the inductor 3. The mold 1 may be configured with a fixed base, the charge 2 being fed via a charging chute 15 directly into the cavity of the inductor 3. The ingot mold 9 may be configured in the form of a cylinder rotatable about its axis or in the form of a chute capable of tilting and progressive motion. Between the mold 1 and the ingot mold 9 an intermediate container 17 may be mounted with independent heating sources 18. In the course of erection the clearance between the inductor 3 and the mold 1 surfaces may be adjusted as well as the inclination, i.e. the inclined slot 13 parameters. Technical result - elimination of the major metal losses into scrap, increase of the metal yield and quality improvement of alloys. |
