Abstract (en)

The procedure uses a continuous feed of molten metal, especially steel, into a mould that supports a funnel-shaped refractory riser (14). The molten metal is delivered to the funnel through an immersed nozzle (22) above a chicane (26) designed to dissipate the basic kinetic energy of the jet from the nozzle, while the cross-section of the funnel's outlet end corresponds to the shape of the metal profile being produced, e.g. H,I, L or T, with its greatest dimension not exceeding 50 mm. The chicane can be formed by a series of pierced holes (30) or a spiral channel in the funnel base (28), reducing the speed of the molten metal flow from an initial 50 - 80 m/min to 5 - 10 m/min.
