摘要
A system for stirring in continuous casting is formed by an inductive stirrer which inductively stirs molten metal in a continuously cast strand and at least one set of two water-cooling pipes positioned in front of the stirrer and having nozzles which eject water cooling-sprays against the strand. The two pipes have ends extending beyond the field and between their ends are electrically isolated from each other and the stirrer. By electrically interconnecting these ends outside of the field, the two pipes form a closed electric loop in which currents induced by the stirrers field cancel so that the net current flow is zero and the stirrer's field is not shielded from the strand.
