Obtención simultánea de ferroaleación multicomponente y escoria a partir de arenas negras, para el desarrollo de consumibles de soldadura por arco eléctrico

Abstract

En este trabajo se expone una caracterización química y mineralógica de las arenas negras del placer Mejías de Sagua de Tánamo, el más importante placer litoral de playa del noroeste de Cuba Oriental. A partir de estas caracterizaciones se desarrolla una estrategia de cálculo para la confección de la carga metalúrgica, que permite obtener, simultáneamente, al ser procesada por reducción carbotérmica en un homo de arco eléctrico, una ferroaleación multicomponente y una escoria útil para la confección de consumibles de soldadura por arco eléctrico. El polvo de la escoria obtenida se aglomera con vidrio líquido. Los pelets resultantes y su comportamiento en la soldadura automática por arco sumergido (SAW), presentan propiedades metalúrgicas y tecnológicas que satisfacen los requisitos de una matriz de un fundente aglomerado. La composición química de la ferroaleación multicomponente está constituida por elementos metálicos: vanadio, cromo, molibdeno, titanio y niobio (V, Cr, Mo, Ti y Nb) de alto valor metalúrgico y aleante, apropiada para la formulación de cargas aleantes de consumibles tanto para la soldadura manual (SMAW) como para la SAW.
