摘要： The invention relates to a railroad renewal method and device, the method including, in particular: the removal of the old rail (A), the installation of the new rail (B) and the primary adjustment of the temperature of said new rail to a set value (T1) at a point (C) located upstream of and close to the attachment area (F) on a crosstie (H). The thermodynamic behavior of the intermediate section (R) of the new rail (B) located between the primary temperature adjustment point (C) and the attachment area (F) is controlled by means of a device, provided with a control and management system (G), such that the temperature of the new rail (B) is uniform, in the cross-section thereof, at a set value (Tf) on the attachment point (F).

摘要： The invention relates to a method to replace a rail part of a railway wherein prior to severing the original the mechanical stress in the rail determined in situ, such as measured or calculated, which data is used during replacing the rail part by welding to bring back the original stress free condition. The rail is demounted across a predetermined length from its mounting to the foundation and temporarily brought in a curved shape, which curved shape is brought back to the original shape during uniting the rail by welding. Use is made of work train comprising an excavator and two wagons. Use is also made of a special clamping unit to press the rail ends against each other during butt welding.

摘要： La présente invention concerne un dispositif de soudure aluminothermique.
Ce dispositif, destiné à l'aboutement de deux pièces métalliques telles que des rails de chemin de fer (1, 2), comporte un moule (10) et un creuset (11) dont les faces respectivement supérieure (23) et inférieure (53) présentent des creux et/ou reliefs respectifs (15, 56, 57, 69, 70, 82) mutuellement complémentaires, tels qu'ils autorisent le dépôt du creuset (11) sur le moule (10), dans une position dans laquelle le trou de coulée (40) du creuset (11) et le godet de coulée (15) du moule (10) sont tournés respectivement vers le bas et vers le haut et coaxiaux.
Le positionnement correct du creuset (11) par rapport au moule (10) est ainsi assuré ; en outre, le creuset (11) se prête à une réalisation sous une forme le destinant à un usage unique, en un matériau choisi à cet effet et avantageusement différent du matériau utilisé pour le moule (10).摘要翻译： 该装置用于邻接两个金属部件如铁路轨道（1,2），包括一个模具（10）和一个坩埚（11），其中上部（23）和下部（53）面分别相互互补 中空和/或浮雕（15,56,57,69,70,82），使得它们允许从坩埚（11）沉积到模具（10）中的坩埚的出口（40）的位置 （11）和模具（10）的浇注衬套（15）分别向下和向上转动并且是同轴的。 因此确保坩埚（11）相对于模具（10）的正确定位; 此外，坩埚（11）自身以为单次使用的形式生产，由为此目的选择的材料制成，并且其有利地不同于用于模具（10）的材料。 ...

摘要： Method for the aluminothermic welding of rails, involving the steps of: - triggering an aluminothermic reaction in a crucible (2), - pouring the metal resulting from said reaction into the mould (1) so as to fill the moulding cavity from the rail flange, - after filling the cavity, triggering a second aluminothermic reaction above the rail head, and pouring the metal resulting from said reaction into the cavity in the region of the rail head. The mould (1) used in the method is designed to fit over the ends of two rails to form a moulding cavity (10) comprising a crucible (4) positioned above the rail head region so that it can be fed with molten metal of the cavity (10) via a secondary passage (42).

摘要： In a method for heating rails by means of electric current, a current source (1) is connected to two rails (B, C), in such a manner that the rails are connected in series. Then a current is led through the rails and the rails are heated to a desired temperature. The heating of the rails (B, C) by means of a series connection is followed by heating of the rails by means of a parallel connection thereof. This method is used for prestressing rails when laying rails in a track, in such a manner that the rails will be at least substantially stressless at a neutral temperature. The invention also comprises an apparatus for heating rails (B, C) by means of electric current, which apparatus includes a current source (1), conductors (2 - 4, 6) as well as connecting elements (5) for connecting said conductors to the rails. Said conductors (2 - 4, 6) and said connecting elements (5) are arranged for successively connecting the current source (1) in series and in parallel to the rails (B, C).
