Latest Patents

Arnaud Lorieux holds a patent for a method and mold for welding the ends of two rail portions. This method involves the aluminothermic welding of rails, which includes several steps. First, an aluminothermic reaction is triggered in a crucible. Next, the resulting metal is poured into a mold to fill the molding cavity from the rail flange. After the cavity is filled, a second aluminothermic reaction is initiated above the rail head, and the resulting metal is poured into the cavity in the region of the rail head. The mold is specifically designed to fit over the ends of two rails, creating a molding cavity that includes a crucible positioned above the rail head region, allowing it to be fed with molten metal via a secondary passage.
