The apparatus comprises a submerged entry nozzle () having outlets in the main casting plane (P) which differ in their direction of output and fall within two categories (). The nozzle is associated with two inductors () opposite each other on each broad face () of the casting mold forming a gap which surrounds the nozzle and produces a traversing magnetic field covering the outlets of at least one category (). Elements are provided for adjusting the intensity of the field or for moving it so as to be able to change the distribution between the outlets of the total flow of molten metal. Implementing the invention makes it possible to adjust at any time that fraction of the metal flow which is directed toward the free surface () with respect to that, main, fraction directed toward the bottom of the mold.

Equipment for supplying molten metal to a continuous casting ingot mould

An electromagnetic inductor for generating a rotating field for stirring the core of a metal casting while the core is still liquid, which metal casting is to be cooled by external water circulation. The excitation winding which is to be mounted on each of its pole pieces must, prior to this, be fixed around a tubular winding support so as to form an annular winding block. The block is then fitted on the pole piece and locked thereto in reversible manner. The inductor may be used in facilities for continuous casting of steel products.
