Abstract

Procedimiento para el revestimiento por inmersión en baño fundido de una cinta metálica (M) con un recubrimiento metálico, - en el que la cinta metálica (M) se conduce en paso continuo a través de un baño de fusión (3), - en el que el grosor del recubrimiento metálico existente sobre la cinta metálica (M) en su salida del baño de fusión (3) se ajusta mediante un dispositivo rascador (7), y - en el que escoria (S) existente en el baño de fusión (3) es arrastrada por un flujo de gas (G1, G2) de modo que se aleja de la cinta metálica (M) que sale del baño de fusión (3), caracterizado por que para arrastrar la escoria (S) de modo que se aleja de la cinta metálica (M) se aplica mediante al menos una boquilla (10, 11) dispuesta lateralmente de uno de los bordes longitudinales (L1, L2) de la cinta metálica (M) que sale del baño de fusión (3) un flujo de gas (G1, G2) orientado a lo largo de la superficie (6) del baño de fusión (3) y de manera transversal a la dirección de transporte (F) de la cinta metálica (M), que fluye a lo largo de la cinta metálica (M).Process for molten bath coating of a metallic strip (M) with a metallic coating, - in which the metallic strip (M) is passed continuously through a molten bath (3), - in which that the thickness of the metallic coating existing on the metallic strip (M) at its exit from the molten pool (3) is adjusted by means of a scraper device (7), and - in which slag (S) existing in the molten pool ( 3) is dragged by a flow of gas (G1, G2) so that it moves away from the metal strip (M) that comes out of the molten pool (3), characterized in that to drag the slag (S) so that it is away from the metal strip (M) a gas flow (G1, G2) oriented along the surface (6) of the molten pool (3) and transversely to the direction of transport (F) of the metal ribbon (M), which flows along of the metallic tape (M).
