Abstract

Los sistemas y los métodos correspondientes que se describen en la presente proveen un manto inerte efectivo sobre una superficie de metal (metal solido caliente (carga) o metal fundido) en un contenedor corno un horno de induccion. El sistema incluye un contenedor de metal y un sistema configurado para entregar criogeno inerte bifásico hacia el metal. El sistema de entrega puede incluir una lanceta dispuesta en la parte superior del contenedor. La lanceta tiene un capuchon que dirige tanto un lujo de criogeno líquido como un flujo de gas vaporoso hacia la superficie del metal. El criogeno líquido pone en contacto la superficie del metal, generando un volumen de gas en expansion sobre la superficie de metal. El criogeno vaporoso crea un vapor de refuerzo que retarda la velocidad de expansion del gas de expansion, localizando el gas de expansion sobre la superficie del metal.
