Abstract

METODO DE CONTROL DEL GRADO DE EXPOSICION DE UN ARCO ELECTRICO DENTRO DE UN HORNO QUE TIENE UNA CARGA FUNDIDA, POR EJEMPLO UN HORNO DE ARCO EN EL QUE EL ESPECTRO DE FRECUENCIA CARACTERISTICO DE LAS ONDAS DE LA FUENTE ASOCIADA CON (A) LA EXPOSICION DE ARCO Y (B) LA INMERSION DEL ARCO, ESTAN PREDETERMINADAS, Y EN EL QUE LAS SEÑALES INDICATIVAS, POR EJEMPLO DE LA CORRIENTE DEL ARCO, EMITIDAS DURANTE EL FUNCIONAMIENTO SE MIDEN Y PROCESAN, EFECTUANDOSE UNA COMPARACION CON UN NIVEL ESTABLECIDO A PARTIR DE ESTAS SEÑALES CARACTERISTICAS PARA SUMINISTRAR ASI UNA INDICACION DEL GRADO DE EXPOSICION DEL ARCO. EL ESPECTRO PREDETERMINADO DE LA FRECUENCIA CARACTERISTICA SELECCIONADO PUEDE SER EL CONTENIDO ARMONICO DE LA CORRIENTE DEL ARCO.
