Abstract

DONDE EL SISTEMA COMPRENDE UN GENERADOR DE SENALES Y UN PROCESADOR DE SENALES, ESTANDO EL PROCESADOR CONECTADO A UN CONJUNTO DE ELECTRODOS, QUE ATRAVIESAN LA CARCASA DEL CONVERTIDOR O REACTOR PIROMETALURGICO, EN CONTACTO CON LAS FASES DE METALES LIQUIDOS Y/O ESCORIA DE MODO QUE QUEDEN UBICADOS EN LA ZONA DONDE INTERESA CONOCER LAS ALTURAS DE LOS NIVELES DE ESCORIA Y FASES O NIVELES METALICOS, Y UNA VEZ INSTALADOS LOS ELECTRODOS CONFIGURAN UN CONJUNTO DE RESISTENCIAS EN SERIE POR DONDE CIRCULA LA SENAL ELECTRICA PROVENIENTE DEL GENERADOR. UN CONJUNTO DE ELECTRODOS ESTA POR ENCIMA DE UN NIVEL DE FASE A DETERMINAR, Y CO-LINEALMENTE O EN ZIG-ZAG OTRO CONJUNTO ESTA POR DEBAJO DE DICHO NIVEL, ESTANDO COMPUESTO CADA CONJUNTO POR AL MENOS DOS ELECTRODOS, CUANDO SE DESEA DETERMINAR EN FORMA DISCRETA LA ALTURA, Y POR AL MENOS UN ELECTRODO CUANDO SE DESEA DETERMINAR EN FORMA CONTINUA DICHA ALTURA. EL METODO INCLUYE MEDIR LA RESISTENCIA ELECTRICA DE LAS FASES DE METALES LIQUIDOS Y/O ESCORIA, DE MODO QUE POR DIFERENCIA DE LAS RESISTENCIAS ELECTRICAS DETECTADAS DE CADA FASE SE DETERMINA LA ALTURA EN QUE SE ENCUENTRA CADA UNA DE ELLAS, CONSISTIENDO LA MEDICION EN DETERMINAR LA CAIDA DE POTENCIAL ENTRE UN CONJUNTO DE ELECTRODOS DISPUESTOS A DIFERENTES ALTURAS EN LA CARCASA DEL REACTOR, Y CUANDO LA CORRIENTE CIRCULA SE INFIEREN LAS RESISTENCIAS ELECTRICAS QUE OFRECEN LAS REGIONES COMPRENDIDAS ENTRE DICHOS ELECTRODOS OBTENIENDO MEDICION EN TIEMPO REAL DE LOS NIVELES DE ALTURA DE DICHAS FASESWHERE THE SYSTEM INCLUDES A SIGNAL GENERATOR AND A SIGNAL PROCESSOR, THE PROCESSOR BEING CONNECTED TO A SET OF ELECTRODES, WHICH PASS THROUGH THE CASE OF THE PYROMETALLURGIC CONVERTER OR REACTOR, IN CONTACT WITH THE STAGES OF METALS / LIQUID MODES WHICH LOCATED IN THE AREA WHERE IT IS INTERESTED TO KNOW THE HEIGHTS OF THE SCAL LEVELS AND PHASES OR METALLIC LEVELS, AND ONCE THE ELECTRODES ARE INSTALLED, THEY CONFIGURE A SET OF SERIES RESISTORS WHERE THE ELECTRIC SIGNAL FROM THE GENERATOR CIRCULATES. A SET OF ELECTRODES IS ABOVE A PHASE LEVEL TO BE DETERMINED, AND CO-LINEARLY OR IN ZIG-ZAG ANOTHER SET IS BELOW SAID LEVEL, EACH SET BEING COMPOSED BY AT LEAST TWO ELECTRODES, WHEN DETERMINED IN DEMAND. HEIGHT, AND AT LEAST ONE ELECTRODE WHEN YOU WANT TO CONTINUOUSLY DETERMINE SUCH HEIGHT. THE METHOD INCLUDES MEASURING THE ELECTRICAL RESISTANCE OF THE PHASES OF LIQUID METALS AND / OR SLAG, SO THAT DUE TO THE DIFFERENCE OF THE ELECTRICAL RESISTANCES DETECTED IN EACH PHASE, THE HEIGHT AT WHICH EACH OF THEM IS FOUND IS DETERMINED, DETERMINING THE MEASUREMENT POTENTIAL DROP BETWEEN A SET OF ELECTRODES ARRANGED AT DIFFERENT HEIGHTS IN THE REACTOR CASE, AND WHEN THE CIRCULAR CURRENT IS INFERED THE ELECTRICAL RESISTANCES OFFERED BY THE REGIONS INCLUDED BETWEEN THESE REAL-TIME MEASURED ELECTRODES FROM NECESSARY MEASURED ELECTRODES
