Abstract

La invención se refiere a un método para la soldadura aluminotérmica de rieles, que comprende los pasos de: - iniciar una reacción aluminotérmica en un crisol (2), - colar el metal derivado de dicha reacción en el molde (1), para llenar la cavidad de moldeo iniciando desde la base del riel, - después del llenado de la cavidad de moldeo, iniciar una segunda reacción aluminotérmica por arriba del cabezal del riel y colar el metal derivado de dicha reacción en la cavidad de moldeo en la región del cabezal del riel; la invención también se refiere a un molde (1) adaptado para ajustarse sobre los dos extremos del riel para formar una cavidad de moldeo (10), que comprende un crisol (4) colocado por arriba de la región del cabezal del riel para que se alimente con el metal fundido desde la cavidad de moldeo (10) por medio de un canal secundario (42).
