PROCESS OF WELDING BY ALUMINUM-THERMAL INTERSTITIAL CASTING OF RAILS WITH MOLDED STEEL ALLOY IN THE FIELD OF RAIL MUSHROOM

摘要

The invention relates to a process for the aluminothermic welding of rails, the aluminothermically produced steel being poured into a refractory mold surrounding the rail ends which are to be joined, and alloying additives being contacted with that part of the steel which runs out of the reaction crucible and forms the weld in the rail head region, wherein the alloying with the alloying additives is carried out after the completion of the aluminothermic reaction and separation of the steel from the slag via the diverting plug in the mold, and the overflow in the is closed.
