Device and corresponding method for the continuous casting of molten materials, comprising a vertical duct (1') having the shape of a funnel (1) made of refractory material for receiving molten material, and a second duct (13') where the molten material is cooled off, the two ducts being set one on top of the other and being axially aligned. The molten material is injected into the channel, around a stretch of which electromagnetic means (4-9) are set for generating magnetic forces on the molten material, the said means consisting of a plurality of windings (4-8) of electrically conductive material and of a ferromagnetic core (9) and may be electrically supplied to produce a magnetic flux along the direction of the channel, thus producing a set of forces acting on the molten material (2), which are directed orthogonally with respect to the direction of the said magnetic flux so as to maintain detachment of the outer surface of the molten material (2) from the walls of the channel. <IMAGE> |
