Abstract: The mold for aluminothermic welding of rails of longitudinally aligned railroad, comprises pieces of rigid refractory material such as an agglomerated sand susceptible to be temporarily assembled around two transversal ends of rail, a mold imprint opened towards the top, two continuous casting staves arranged for leaning against a second zone adjacent to the first zone of each rail, and a compressible coating in liquid form for sealing the support against the welding metal. The mold imprint is arranged to receive a welding metal at liquid state by casting and enclosing both ends. The mold for aluminothermic welding of rails of longitudinally aligned railroad, comprises pieces of rigid refractory material such as an agglomerated sand susceptible to be temporarily assembled around two transversal ends of rail, a mold imprint opened towards the top, two continuous casting staves arranged for leaning against a second zone adjacent to the first zone of each rail, and a compressible coating in liquid form for sealing the support against the welding metal. The mold imprint is arranged to receive a welding metal at liquid state by casting and enclosing both ends, a gap spared between them and a first zone of each rail. The compressible coating is limited at the parts of each casting stave corresponding to a bottom, a side and a top of a flange of the rail. The flange corresponds to the sides of a web of the corresponding rail. The rigid refractory material is directly exposed in the parts of the stave. A spacing is less than the spacing between the top and bottom of the head of the rail. The rigid refractory material is treated to facilitate its selective removal in the parts of each casting stave thus allowing an adaptation of the mold to rails. A localized lamination of each casting stave is used in its part corresponding to the bottom of the corresponding rail head. Markers are used for selective removal of the refractory material, and constituted by gradings in the localized lamination. The two casting staves are reciprocally symmetrical in relation to a plane coinciding roughly with a transversal plane of symmetry between the two rail ends. A third part is arranged below each rail, and constitutes parts of the staves corresponding to a bottom of the flange. The coating comprises a refractory fiber felt bound by a refractory binding that is adhered to the parts by a refractory glue.
