Abstract

La presente invención se refiere a un método para producir acero que contiene metal de bajo punto de fusión seleccionado del grupo que consiste de pb y Bi, caracterizado por: mantener el metal de bajo punto de fusión en un estado fundido a una temperatura comprendida entre 271 y 327,4 grados C en un recipiente, y permitir que fluya por gravedad una cantidad controlada del metal fundido de bajo punto de fusión abajo a través de una varilla hueca tapada colocada por encima de la abertura de una boquilla en el fondo de un segundo recipiente de acero fundido, hasta el acero fundido contenido en este segundo recipiente; siendo operada la varilla por medio de una palanca.
