Abstract

Un método para agitar metal fundido durante su tratamiento dentro de un recipiente metalúrgico, que comprende: A. proporcionar un recipiente metalúrgico orientado verticalmente para alojar una masa principal de metal fundido dentro de una periferia definida por un revestimiento refractario; B. establecer un conducto de paso del metal fundido contiguo a dicha periferia del recipiente, estando dicho conducto de paso: (I) parcialmente definido entre una columna refractaria orientada sustancialmente de modo vertical en combinación con una estructura de pared refractaria que presenta una porción central orientada verticalmente y sustancialmente plana; y (II) comunicando con dicha masa principal del metal fundido de dicho recipiente, de modo que: el movimiento no turbulento sustancialmente orientado de modo horizontal del metal fundido, entre dicha columna refractaria y dicha estructura de pared refractaria: permite que (a) entre en dicho conducto de paso, (b) atraviese dicho conducto de paso, y (c) retorne el metal fundido desde dicho conducto de paso a dicha masa principal de metal fundido de dicho recipiente; C. colocar un núcleo alargado magnéticamente permeable que está dispuesto sustancialmente simétrico en relación a un eje longitudinal centralmente localizado de dicho núcleo, D. colocar una pluralidad de arrollamientos conductores eléctricamente individuales en una relación espaciada linealmente a lo largo de dicho núcleo alargado, E. establecer cíclicamente líneas de ujo magnético para in uir en dicho metal fundido haciendo que adquiera dicho movimiento no turbulento orientado horizontalmente en dicho conducto de paso, con dichas líneas de flujo magnético que están: (I) concentradas en el metal fundido en dicho conducto de paso, y (II) establecidas por excitación eléctricamente alterna tales como los arrollamientos linealmente espaciados; F. limitar verticalmente dicho movimiento horizontalmente orientado de metal fundido a través del conducto de paso por medios de tabiques selectivamente localizados: (I) contiguos a una porción de superficie superior de dicho cuerpo principal de metal fundido de dicho recipiente, y (II) contiguos a una porción de fondo de dicha masa principal de metal fundido de dicho recipiente.
