Process for electromagnetic stirring

摘要

A process and installation for stirring metal in a continuous-casting mould by forming in the ingot mould an electromagnetic induction field rotating about an axis parallel to, or coinciding with, the axis of the ingot mould by means of a stator supplied with alternating inducting current. According to the invention, the liquid metal surrounded by a ring of solidified metal and the copper ingot mould is driven in rotation by employing a field produced by an inducing current of frequency lower than 10 Hz.
