Abstract:
A semi-liquid metal processing apparatus and method are presented in which a semi-liquid metal and/or semi-solid metal is introduced into a crucible and his electromagnetically stirred at a first frequency while cooling, and thereafter sidewalls of a metal charge formed of the semi-liquid metal and/or semi-solid metal are partially melted prior to tilting the crucible for removal of the metal charge.
