    Abstract: UN METODO DE AGITACION DE INDUCCION EN DONDE EL METAL FUNDIDO SE AGITA ELECTROMAGNETICAMENTE DURANTE EL FUNDIDO CONTINUO EN UN MOLDE INCLUYE CONTROL DE DEPRESION CURVA, O PARA DISMINUIR O PARA AUMENTAR LA AGITACION DEL METAL FUNDIDO PRODUCIDO POR EL AGITADOR ELECTROMAGNETICO PRINCIPAL. UN MODIFICADOR DE AGITACION MAGNETICO DE C.A SE COLOCA JUNTO A LA REGION DE LA CURVA PARA PRODUCIR LA AGITACION ELECTROMAGNETICA DEL METAL FUNDIDO EN LA CURVA, O PARA OPONER EL MOVIMIENTO GIRATORIO DEL AGITADOR ELECTROMAGNETICO PRINCIPAL Y PROPORCIONAR UNA SUPERFICIE LIBRE DE TURBULENCIA O PARA AUMENTAR EL MOVIMIENTO GIRATORIO DEL AGITADOR MAGNETICO PRINCIPAL. ESTOS DOS MODOS ALTERNATIVOS DE OPERACION PERMITEN QUE SE UTILICE UNA MAQUINA DE FUNDICION PARA FUNDIR METALES QUE REQUIERAN VARIAR AMPLIAMENTE LAS CONDICIONES DE OPERACION.
