Abstract
This invention relates to an improvement in the process for performing aluminothermic rail connection weldings, in which the rail ends to be welded together and being laid with a gap are enclosed with a fireproof, prefabricated casting mold producing a weld reinforcement covering the gap, and aluminothermically-produced steel is poured into the casting mold cavity, the improvement comprising pouring the steel melt into the casting mold in the form of at least two separate casting streams positioned opposite each other in the longitudinal rail direction, whereby the casting streams are so guided that they will intermix approximately in the area of the rail head center of the two rails to be welded together. The invention also relates to a casting mold for performing the process.
