Abstract
An electromagnetic induction melting furnace to control an average nominal diameter of the TiB2 cluster of the Al—Ti—B 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 TiB2 grains of the Al—Ti—B alloy to control the average nominal diameter of the TiB2 cluster.
