PURPOSE:To provide a titled device which stirs and heats a molten metal and desulfurizes effectively said metal by providing a vessel for molten metal consisting of a refractory material in a cylindrical induction coil, and communicating the lower part of the vessel and a charging port positioned at the same level as the upper part of the vessel. CONSTITUTION:An induction coil 1 formed by winding a water cooling pipe into a cylindrical shape is supported together with an iron core 5 by annular supports 2, 3, and a vessel 4a for molten metal consisting of a refractory material is provided in the coil 1. A communication pipe 4b of a refractory material which communicates the bottom of said vessel and a charging port 4c positioned at the same level as the vessel 4a is provided, whereby a furnace body 4 is constituted. The molten metal R supplied, via an inflow spout 6 for the molten metal, from a cupola, (not shown in figure), is added with a desulfurizing agent from an addition pipe 7 for the desulfurizing agent in the vessel 4a; at the same time, stirring flow is induced therein in an arrow direction by the coil 1 and the molten metal is heated, whereby the molten metal is effectively desulfurized. The desulfurized metal overflows from the port 4c into a casting mold (not shown in figure) according to the supply rate of the molten metal from the cupola. |
