Abstract

Un sistema de control para un proceso de refusión por arco en vacío (VAR) para un metal incluye una fuente de energía de corriente directa (CD), un accionador de ariete, un sensor de goteo corto de voltaje, y un controlador, el cual incluye un procesador; el sensor de goteo corto puede ser configurado para medir una frecuencia de goteo corto del arco eléctrico durante un periodo de tiempo; el controlador está configurado para determinar una longitud de intervalo de arco en tiempo real entre la punta del electrodo y la reserva de fusión con base en una correlación entre la frecuencia de goteo corto y la longitud del intervalo de arco; el controlador además está configurado para controlar la entrada de potencia al electrodo mediante el suministro de energía CD determinado un nivel de potencia de entrada para introducción al electrodo con base en la longitud del intervalo de arco en tiempo real, el nivel de potencia de entrada configurado para generar una longitud de intervalo de arco deseada, mediante el suministro de energía CD, al nivel de potencia de entrada.
