Abstract

BOBINA DE CALENTAMIENTO POR INDUCCION PARA EL TRATAMIENTO TERMICO DE TUBOS METALICOS. SE DESCRIBE UNA BOBINA DE CALENTAMIENTO POR INDUCCION PARA EL TRATAMIENTO TERMICO DE TUBOS METALICOS MEDIANTE LA CREACION DE ESFUERZOS RESIDUALES DE COMPRESION EN LA SUPERFICIE EXTERNA DEL TUBO METALICO. LA BOBINA DE CALENTAMIENTO POR INDUCCION ESTA ADAPTADA PARA RODEAR EL TUBO METALICO A UNA CIERTA DISTANCIA DEL MISMO, E INCLUYE UNA PLURALIDAD DE ELEMENTOS CONDUCTORES ELECTRICOS HUECOS DE FORMA TOROIDAL PARA CALENTAR POR INDUCCION EL TUBO METALICO ASI COMO UNA PLURALIDAD DE TUBOS DE AGUA HUECOS DE FORMA TOROIDAL QUE INCLUYEN UN NUMERO CONSIDERABLE DE BOQUILLAS PARA PROYECTAR AGUA DE REFRIGERACION HACIA EL TUBO METALICO FORMANDO EN EL UNA PELICULA DE AGUA UNIFORME, ESTANDO LAS BOQUILLAS INCLINADAS RESPECTO A LA DIRECCION LONGITUDINAL DEL TUBO METALICO.
