    • This present invention concerns a mould for the aluminothermic welding of railway rails. The compressible lining (58) used to seal the moulding die in relation to leakages of the weld metal in the liquid state is limited to the parts of the contact surfaces (52) of the parts (19) of the mould on the rails to be welded, corresponding to the bottom, the sides and the top of the foot, to the sides of the web and below the head. The rigid refractory material of the parts (19) is exposed in the parts (67, 71) of the contact surfaces corresponding to the sides and the top of the head, and suitable to be removed selectively from the latter. This makes it easy to adapt the mould to rails with different degrees of wear.
    • 本发明涉及铁路轨道的铝热熔接模具。 用于密封成型模具的可压缩内衬(58)相对于处于液态的焊接金属的泄漏而被限制在轨道上的模具的部件(19)的接触表面(52)的部分 焊接,对应于底部,侧面和顶部的脚,到网的侧面和头部下方。 部件(19)的刚性耐火材料暴露在对应于头部的侧面和顶部的接触表面的部分(67,71)中,并且适于从后者中选择性地移除。 这使得容易使模具适应不同程度磨损的导轨。
