Abstract

PARA EVITAR EN LO POSIBLE LAS PROYECCIONES DE ESCORIA EN UN SISTEMA DE CONDUCCION DE ESCORIA A UN CONVERTIDOR DE SOPLADO DE ACERO (1) PROVISTO DE UNA LANZA DE SOPLADO (2), CUYA DISTANCIA (A) DESDE LA SUPERFICIE DEL BAÑO (17) SE REGULA SEGUN SEAN LAS FRECUENCIAS SELECCIONADAS POR EL RUIDO DE SOPLADO DE LA ESCORIA, SE REDUCEN A UN VALOR NOMINAL LOS VALORES REALES DE LOS RUIDOS DE SOPLADO, DETERMINADOS PARA LAS DISTINTAS FRECUENCIAS. POR LA DIFERENCIA ENTRE ESTE VALOR NOMINAL RESULTANTE Y EL VALOR FIJADO PREVIAMENTE, SE OBTIENE UN VALOR DE COMPARACION DE UNA PROBABLE PROYECCION DE ESCORIA, A PARTIR DEL CORRESPONDIENTE RUIDO DE SOPLADO. DICHO VALOR SE UTILIZA COMO MEDIDA DE COMPARACION CON UN LIMITE DE PROBABILIDAD Y SI SE SOBREPASA ESTE LIMITE, TIENE LUGAR UNA CORRECCION DE LA DISTANCIA (A) DE LA LANZA, ES DECIR, DE LA CANTIDAD DE OXIGENO APORTADO
