Abstract
Electromagnetic induction heating of open risers presents an energy efficient means to maintain the alloy in its molten state for mass feeding whilst allowing riser size reduction and substantial material savings. This paper presents preliminary simulation results of solidification phenomena in an inductively heated top riser. The electromagnetic field was calculated using a hybrid control volume/integral method to solve the magnetic diffusion equation with accompanying boundary conditions, and used temperature dependent electrical conductivity. The heat transfer equation was solved using the control volume method. Computed results show that it is possible to prevent premature solidification of the riser even though traditional design criteria are violated. The significance of these findings pertaining to sand and ingot casting systems will be discussed.
