Abstract
La presente invención se relaciona de manera general con un método y sistema para el suministro de una corriente continua de hierro reducido directo caliente (HDRI) a partir de un horno de cuba de reducción directa (DR) o un horno de recalentamiento de hierro reducido directo (DRI) a un punto fuera del horno de cuba DR o del horno de recalentamiento DRI en donde la corriente de HDRI se divide en por lo menos dos corrientes de HDRI. La primera corriente HDRI se envía continuamente a una planta de elaboración de lingotes caliente por gravedad en un sistema de conducto cerrado. La segunda corriente de HDRI se envía continuamente a un horno de fundición adyacente, también por gravedad, en un sistema de conducto cerrado, con una bandeja de descarga y alimentadores, o por una combinación de gravedad en un sistema de conducto cerrado, también con una bandeja de descarga y alimentadores y un transportador de carga generalmente horizontal. Opcionalmente, se utiliza una tercera corriente de HDRI para alimentar continuamente recipientes de transporte calientes múltiples.
