Abstract
PROCEDIMIENTO PARA REGULAR DE MANERA PRECISA LA CADENCIA DE INTRODUCCION Y EL CONTENIDO EN ALUMINA DE UNA CUBA DE ELECTROLISIS IGNEA, DESTINADA A LA PRODUCCION DE ALUMINIO SEGUN EL PROCEDIMIENTO HALL-HEROALT. CONSISTE EN INTRODUCIR LA ALUMINA DIRECTAMENTE EN EL BAÑO DE CRIOLITA FUNDIDA A TRAVES DE UN ORIFICIO MANTENIDO ABIERTO EN LA COSTRA COAGULADA, Y EN MODULAR LA CADENCIA DE INTRODUCCION DE LA ALUMINA EN FUNCION DE LAS VARIACIONES DE LA RESISTENCIA INTERNA DE LA CUBA, DURANTE INTERVALOS DE TIEMPO PREDETERMINADOS, ALTERNANDO CICLOS DE IGUAL DURACION PARA LA INTRODUCCION DE ALUMINA A CADENCIA MAS LENTA Y A CADENCIA MAS RAPIDA, QUE LA CADENCIA QUE CORRESPONDE AL CONSUMO DE LA CUBA.
