Abstract

EL PROCEDIMIENTO DE TRATAMIENTO POR IRRADIACION LASER AL PASO DE LA SUPERFICIE DE UN PRODUCTO DE MATERIAL MAGNETICO CONSISTE EN EFECTUAR, SIMULTANEAMENTE, EN TODA UNA LINEA QUE CORRESPONDE A UN LARGO DEL PRODUCTO TRATADO, LA IRRADIACION LASER. EL DISPOSITIVO ESTA EQUIPADO CON UNA FUENTE (10) DE IRRADIACION LASER Y COMPRENDE UN ANAMORFOSOR (30) QUE OVALIZA EL HAZ INCIDENTE, UNA COMBINACION OPTICA (20) DISPUESTA ENTRE LA FUENTE (10) Y EL PRODUCTO (P) Y FABRICADA CON DOS LENTES (21, 22) CILINDRICAS, UNA DIVERGENTE Y LA OTRA CONVERGENTE, Y CUYOS EJES GEOMETRICOS SON ORTOGONALES PARA TRANSFORMAR EL HAZ (F) EMITIDO DE LA FUENTE (10) EN UN TRAZO (T) RELATIVAMENTE ESTRECHO ORIENTADO APROXIMADAMENTE TRANSVERSALMENTE RESPECTO A LA DIRECCION DEL MOVIMIENTO. APLICACION EN CHAPAS CON USO ELECTROMAGNETICO.
