摘要： In order to reduce the residual stresses which occur in the region of a fusion weld of two rail ends (1,2), in order to reduce, in particular to make uniform, the cooling-down rate and--associated with this--the crystallization process within the solidifying weld material, a casting mold is proposed which is equipped with a system of risers (9) and air vents (10) which are designed symmetrically with respect to a longitudinal center plane (5) and a transverse center plane (3) of the welded joint, the risers (9) and the air vents (10) being physically distributed as a function of geometric parameters of the rail foot (8) and of the weld bead (4), and the cross sections of the air vents (10) being dimensioned as a function of the cross sections of the risers (9). The positioning of the air vents (10) and of the risers (9) according to the invention in conjunction with the cross-sectional dimensioning of the former allows cooling conditions to be set up in which the weld material is effectively prevented from solidification starting on the outside with respect to the rail profile, and in which a considerable reduction in the residual stresses can be achieved, with the cooling process being slowed down overall.

摘要： A method for grinding the running and/or guide surfaces of rails or the like, where the running surfaces are ground by an endless revolving abrasive belt which can be moved against the running surfaces, wherein the abrasive belt revolves transversely to the longitudinal axis of the rail and embraces, at least partially with prestress, the running and/or guide surfaces. An apparatus for performing the method includes a mobile grinding machine, which an endless abrasive belt, guided at least on one rail of the track, which abrasive belt revolves over a drive roller and a reversal arranged at a distance therefrom and which can be moved by these against the surfaces of the rail to be ground. The reversal is formed of two reversing rollers which have a comparatively small spacing from each other, that the axes of the reversing rollers and of the drive roller 19 being arranged to be parallel to the longitudinal axis of the rail. Thus, the abrasive belt revolves transversely to the longitudinal axis of the rail and at least one reversing roller can be lowered beneath the upper edge of the running surface of the rail for partially embracing the surfaces of the rail.

摘要： Aluminothermically produced steel is poured into a casting mold which surrounds the two rail ends. A cooling agent is applied to the surfaces of the rail heads of the rail portions adjacent the two casting mold halves. The cooling agent is applied after the molten steel has been poured into the casting mold until the steel has solidified. The cooling agent may be applied until the projecting material and the casting mold halves has been sheared off. A casting mold for carrying out the method includes two casting mold halves which each has a groove for receiving a sealing paste in the inner surfaces thereof facing the rail ends, wherein the groove extends along the outer contour of the casting mold halves.
