ELECTROMAGNETIC INDUCTION ELECTRIC MELTING FURNACE USED FOR CONTROLLING AVERAGE NOMINAL DIAMETER OF TIB2 AGGREGATES IN AL-TI-B ALLOY

摘要

An electromagnetic induction melting furnace to control an average nominal diameter of the TiC cluster of the Al-Ti-C alloy includes a main body containing the melted alloy; and a multi-layer coil disposed on the main body, wherein a frequency of the alternative current of each coil of the multi-layer coil is different, and the alloy is heated by inducing a magnetic field generated by the alternative currents. The selection of the frequency and the changeable magnetic field may reduce the cohesion force between the TiC grains of the Al-Ti-C alloy to control the average nominal diameter of the TiC cluster.
