Abstract

Con el fin de disminuir o suprimir oscilaciones (el denominador efecto de "contraataque") en convertidores de inyección lateral o por el fondo, especialmente para la obtención de aceros al carbono o aceros inoxidables se propone que el sistema de alimentación de gas (3) del convertidor tenga un dispositivo de estrangulamiento de alimentación (7) delante o asignada a la boquilla (5) que reduzca o interrumpa periódicamente la alimentación de gas al interior del reactor. Reivindicación 7: Procesamiento para operar un sistema de alimentación de gas para un reactor metalúrgico de inyección lateral o de fondo con al menos una boquilla (5) dispuesta en la pared lateral y/o en el fondo del reactor, donde se conduce gas a través de una canería (6) del sistema de alimentación de gas (3) a la boquilla (5) y a través de esta al interior del reactor. Caracterizado porque la corriente de gas se reduce o se interrumpe periódicamente en el interior del reactor con frecuencias superiores a 5 Hz.
