The electromagnetic stirring of steel in the machines for the continuous casting process has improved the internal quality of the cast product. Experimental work with stirrers situated at different positions of continuous casting machines of billets has been carried out. The in-mould stirrer is the one that produces a major modification of the billet internal structure, and also the biggest decrease of the central segregation. An in-mould electromagnetic coil has been developed which allows the use of high stirring power without producing an undesirable movement of the liquid steel in the meniscus zone, therefore no mould powders entrapments are produced. It has been developed a method for determining the optimum electric frequency of the stirrer.
