This device, intended for abutting two metallic parts such as railway rails (1, 2), comprises a mould (10) and a crucible (11), of which the respectively upper (23) and lower (53) faces have mutually complementary respective hollows and/or reliefs (15, 56, 57, 69, 70, 82), such that they allow deposition from the crucible (11) into the mould (10), in a position in which the taphole (40) of the crucible (11) and the pouring bush (15) of the mould (10) are turned respectively downwards and upwards and are coaxial. …<??>The correct positioning of the crucible (11) in relation to the mould (10) is thus ensured; furthermore, the crucible (11) lends itself to production in a form intending it for a single use, made from a material chosen for this purpose and which is advantageously different from the material used for the mould (10). …<IMAGE>… |
