Abstract

PROCEDIMIENTO PARA EL CONTROL DEL NIVEL DE METAL FUNDIDO EN CONJUNTOS PARA COLADA VERTICAL, CONTINUA O SEMICONTINUA, EN PARTICULAR UNIDADES DE COLAR EN LAS QUE SE USA UN CAMPO ELECTROMAGNETICO GENERADO POR UNA INDUCTANCIA ANULAR QUE RODEA A LA COLUMNA DE METAL FUNDIDO, PARA CONFORMAR EL METAL QUE SOLIDIFICA.COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE DETECTA EL NIVEL DE METAL FUNDIDO EN LOS MEDIOS DE MOLDEO Y SE GENERA UNA SEÑAL QUE REPRESENTE EL NIVEL DEL METAL FUNDIDO PERCIBIDO; SEGUNDA, SE COMPARA LA SEÑAL QUE REPRESENTA EL NIVEL DE METAL FUNDIDO PERCIBIDO CONUNA SEÑAL QUE REPRESENTA EL NIVEL DE METAL FUNDIDO DESEADO, GENERANDO UNA SEÑAL QUE REPRESENTA LA DIFERENCIA ENTRE LAS DOS SEÑALES; Y POR ULTIMO, SE CONTROLA LA VALVULA DE CONTROL DEL FLUJO CON UNOS MEDIOS DE CONTROL QUE RESPONDEN A LA SEÑAL DIFERENCIA.
