Abstract
SE PRESENTA UN METODO PARA LA AGITACION ELECTROMAGNETICA DEL METAL LIQUIDO (14) EN HORNOS DE ARCO ELECTRICO DE CORRIENTE CONTINUA, QUE COMPRENDE UNA SOLERA (35) DEFINIDA POR UN SUELO (13) Y POR UNAS PAREDES LATERALES (15), INCLUYENDO LOS HORNOS DE ARCO ELECTRICO UN CATODO CENTRAL (11) QUE COOPERA CON ANODOS (12) DISPUESTOS EN EL SUELO (13) DEL HORNO Y QUE SON ALIMENTADOS POR UNA CORRIENTE PRINCIPAL (I SUB,O}), CARACTERIZADO POR LA EXISTENCIA DE UN SISTEMA ELECTROMAGNETICO QUE GENERA UN CAMPO MAGNETICO DENTRO DEL METAL LIQUIDO (14) CUYOS COMPONENTES VERTICAL (B SUB,Z}) Y RADIAL (B SUB,R} INTERACTUAN RESPECTIVAMENTE CON LOS COMPONENTES RADIAL (J SUB,R}) Y VERTICAL (J SUB,Z}) DE LA CORRIENTE TOTAL PRESENTE EN EL METAL LIQUIDO (14), UTILIZANDO EL METODO UN PRIMER SISTEMA ELECTROMAGNETICO QUE COMPRENDE AL MENOS UN PRIMER BOBINADO (19) A TRAVES DEL CUAL FLUYE UNA CORRIENTE (I SUB,1}) Y QUE ACTUA DESDE DENTRO DEL SUELO (13) Y DE LAS PAREDES (15) DE LA SOLERA (35), Y UN SEGUNDO SISTEMA ELECTROMAGNETICO QUE GENERA UNA CORRIENTE SECUNDARIA INDUCIDA (I SUB,3}) ENTRE ANODOS ADYACENTES (12) QUE CIRCULA A TRAVES DEL METAL LIQUIDO (14). SE PRESENTA UN DISPOSITIVO PARA REALIZAR EL METODO MENCIONADO, QUE CONSTA DE UN PRIMER BOBINADO (19) A TRAVES DEL CUAL FLUYE UNA CORRIENTE (I SUB,1}), COMPRENDIENDO ESTE PRIMER BOBINADO (19) UNA PLURALIDAD DE ESPIRALES (20), ALGUNAS DE LAS CUALES, AL MENOS, ESTAN DISPUESTAS DENTRO DEL REFRACTARIO DE LA SOLERA (35) EN COOPERACION CON EL SUELO (13) Y CON AL MENOS UN SEGMENTO VERTICAL DE LAS PAREDES LATERALES (15).
