    Method and device for the aluminothermic welding of rails

    New search for: THURU JEAN-JACQUES
    New search for: WINIAR LIONEL

    The invention concerns a method for the aluminothermic welding of rails, comprising the steps of: triggering an aluminothermic reaction in a crucible (2), casting the metal derived from said reaction into the mold (1), so as to fill the molding cavity starting from the foot of the rail, after filling of the molding cavity, triggering a second aluminothermic reaction above the rail head, and casting the metal derived from said reaction into said molding cavity in the region of the rail head. The invention also concerns a mold (1) adapted to fit over the two rail ends to form a molding cavity (10), comprising a crucible (4) arranged above the region of the rail head so that it is fed with molten metal from the molding cavity (10) via a secondary channel (42).
