A method of preventing aluminium from splashing and spitting from a crucible when melting and vapourizing aluminium in vacuo with the aid of induction heating and comprising placing a graphite ring (4) around the aluminium (2) to be melted in the crucible (1). If the aluminium first melts locally at a given point in the toroidal crucible (1), the graphite ring (4), which has a much higher melting point than the aluminium body (2), will constantly ensure that electric contact is achieved around the aluminium body, thereby preventing the occurrence of induction lifting forces that in turn result in aluminium splashes. |
