Abstract

Un método para hacer funcionar una tobera de agitación inferior de un BOF que tiene una boquilla interna rodeada por una boquilla anular, que incluye, durante una fase de vertido de metal caliente y una fase de soplado, hacer fluir un gas inerte a través de ambas boquillas; durante una fase de vaciado, iniciar un flujo de un primer reactante a través de la boquilla interna y un flujo de un segundo reactante a través de la boquilla anular, y cesar el flujo de gas inerte a través de las boquillas, en donde el primer y segundo reactantes incluyen combustible y oxidante, respectivamente, o viceversa, de modo que se forma una llama a medida que el combustible y el oxidante salen de la tobera; durante una fase de salpicado con escoria, continuar los flujos de combustible y oxidante para mantener la llama y después de terminar la fase de salpicado con escoria y comenzar otra fase de vertido de metal caliente, iniciar un flujo de gas inerte a través de ambas boquillas y cesar los flujos del primer y segundo reactantes.
