ABSTRACT:
The solid metal to be melted is placed within an induction coil which is adapted to provide a greater electomagnetic force towards the lower portion of the quantity of metal. The solid metal rests on a support, having an opening therethrough, which is kept at a low temperature relative to the metal as it melts. When energy is provided to the coil, the metal melts from the top downward, but the concentration of electromagnetic force towards the bottom of the metal causes the liquid metal to retain a cylindrical shape. When most of the metal is melted, the liquid metal passes through the opening in the support into a casting mold.
