Abstract
PROCEDIMIENTO DE REGULACION DEL CONTENIDO DE ALUMINA DEL BAÑO DE UNA CUBA DE PRODUCCION DE ALUMINIO POR ELECTROLISIS DE ALUMINA DISUELTA EN UNA SAL FUNDIDA A BASE DE CRIOLITA, QUE CONSISTE EN ALTERNAR FASES DE SUBALIMENTACION DE ALUMINA Y FASES DE SOBREALIMENTACION DE ALUMINA RESPECTO A UN REGIMEN DE CONSUMO TEORICO MEDIO DE ALUMINA DE LA CUBA EN FUNCION DE LOS VALORES CALCULADOS AL TERMINO DE CADA CICLO I DE REGULACION DE DURACION T, DE LA RESISTENCIA MEDIA R(I) MEDIDA EN LOS INDICADORES DE LA CUBA, DE LA VELOCIDAD DE EVOLUCION DE ESTA RESISTENCIA O PENDIENTE DE RESISTENCIA P(I), DE LA VELOCIDAD DE EVOLUCION DE LA PENDIENTE DE RESISTENCIA O CURVATURA C(I) Y DE LA PENDIENTE EXTRAPOLADA PX(I) = P(I) + C(I) X T, QUE SON COMPARADOS RESPECTIVAMENTE CON VALORES DE REFERENCIA PO, CO Y PXO QUE PERMITEN MODULAR, SEGUN UN ALGORITMO DE REGULACION APROPIADO, EL CONTENIDO DE ALUMINA DEL BAÑO EN UNA ZONA DE CONCENTRACION MUY ESTRECHA COMPRENDIDA ENTRE UN 1,5 Y UN 3,5 %.
