MOLTEN COPPER SUPPLYING APPARATUS FOR COPPER DIECASTING USING HIGH FREQUENCY INDUCTION HEATING

摘要

PURPOSE: A molten metal supply apparatus for copper diecasting using high-frequency induction heating is provided to prevent the reduction of product quality due to oxidation and bubbling and low productivity and risk of accidents resulting from the transport of a crucible and injection implemented by a worker. CONSTITUTION: A molten metal supply apparatus for copper diecasting using high-frequency induction heating comprises a melting furnace(10), a molten metal injection unit(20), and a high-frequency oscillator. The melting furnace includes a heating coil(102) which is installed in a wall part around a crucible and melts copper in the crucible and an outlet(105) for discharging molten copper. The molten metal injection unit is installed with a heating coil for maintaining molten copper over the melting temperature. The high-frequency oscillator supplies the heating coils of the melting furnace and the molten metal injection unit with power for high-frequency induction heating.
