Abstract

Un método para detectar escoria fundida en una corriente de colada, entre un recipiente para producir acero, tal como un recipiente metalurgico y lacorrespondiente cuchara. Se usa un dispositivo o dispositivos de imágenes o de deteccioninfrarrojo/s (IR) para reflejar/controlar la corriente de coladarecipiente metalurgico-cuchara, transmitiendo la corriente energía indicativa de si se encuentra presente acero y/o escoria en la corriente en un momento dado.Se realiza el análisis dela escala de grises segun los pixel detectados en la corriente de colada, para determinar el numero de pixel correspondiente alacero y el numero de pixel correspondiente a la escoria en la corriente en un momento dado. Cuando la relacion o elporcentaje de pixel de escoria excede unvalor o numero predeterminado, puede accionarse una alarma para que un operador vuelque el conversor hacia arriba a fin de detener la colada o el conversorpuede ser volcado automáticamente hacia arriba paradetener la colada. El aparato para controlar el sangrado de un recipiente metalurgico comprende unconversor BOF para contener acero fundido y escoria fundida, flotando la escoria fundida en la superficie del acero fundido,incluyendo dicho conversorBOF un agujero de colad a definido en el mismo para permitir que el acero fundido fluya desde allí; un cucharon dispuesto en unaelevacion vertical, debajo del conversor BOF, para recibir el acero fundido que fluye desde el conversor BOF por vía delagujero de colada, forman do unacorriente de colada; un dispositivo de obtencion de imágener para mostrar en imágenes la corriente de colada de acero fundido y de escoria fundida que fluyedesde el agujero de colada al interior del cucharon, a fin dedetectar la presencia de e scoria en la corriente de colada; un sensor para determinar un ángulode inclinacion del conversor; y medios para detener el sangrado cuando se ha detectado una cantidad sustancial de escoria en la corriente de colada ycuando elángulo de inclinacion del conversor es mayor que un valor predeterminado o está dentro de un rango predeterminado. El aparato para detectar escoria fundida
