Definitions
- the invention relates to a method for producing a rail with reduced rolling noise, in particular for use in conjunction with tram rails and in particular in conjunction with curved rails, which have narrow radii, wherein the running surface of the rail provided with at least one, parallel to the rail longitudinal direction, additional material layer which is produced by applying a welding path in the submerged arc welding process (UP). Furthermore, the invention relates to a rail produced by this method.
- UP submerged arc welding process
- Such a method is from the German patent application DE 25 54 704 A1 known.
- rails for rail vehicles are subdivided into sub-surfaces which run along the rail and are arranged at a distance from one another.
- the partial surfaces are applied to the original rail, inter alia, by submerged arc welding or by welding under protective gas with consumable welding wire.
- the material used for the partial surfaces is a metallic filler material, which may also comprise a non-ferrous metal, with a mono- or multiphase bronze having at least 50% copper content and one or more other alloying elements.
- the so-called stick-slip effect can play a role.
- the noise will probably be the same effect as when a wet finger strokes the edge of a half-filled wine glass.
- the object of the invention is therefore to provide a simple and easy to carry out method for producing a rail with reduced rolling noise.
- Another object of the invention is to provide a rail having such a reduced rolling noise.
- a high-alloyed basic welding wire is now used as the welding wire; in particular, a flux-cored wire is used as the welding wire Welding wire used because it has been found that a welding process with solid wires does not lead to the desired result.
- Such welding wires are commonly used in building construction, so that the expert has not come up to the present invention on the idea to use such a combination of materials for the track construction.
- the welding wire according to the invention is provided as a high-alloyed welding wire with a carbon content of between 0.0 and 1.5%, in particular between 0 and 0.5%.
- the manganese content is between 0.0 and 5%, in particular between 0.5 and 3%.
- a silicon content between 0.0 and 1.5, in particular between 0.0 and 1% and a chromium content between 8 and 23%, in particular between 12.0 and 18.0% are provided.
- a nickel content between 1.0 and 10%, in particular between 2 and 6% is added alloyed.
- a good result can be achieved with this welding powder and the welding wire according to the invention, however, sustainable noise reduction becomes possible only when, surprisingly, a certain combination of welding parameters is maintained.
- a welding current should be used which has a current of between 300 and 500 amps, in particular between 370 and 430 amps.
- the voltage of the welding current should be between 20 and 30 volts, in particular between 23 and 26 volts.
- Wire feed rates between 90 and 120 cm / min , in particular between 100 and 115 cm / min are also used according to the invention.
- the adhesive property of the welding track on the upper side of the rail, in particular in the curved area is improved by cutting a groove into the rail before welding.
- a groove can be introduced for example via a special tool that can be moved on the rail and each having a cutting disc for each groove, which is parallel to the direction of travel against the rail engageable.
- the inventive method can be used both in new rails in the manufacturing plant as well as already laid rails on the road.
- the rails are dried before machining, then preferably provided with grooves via the above-mentioned special tool, so that finally can be done with an above-also movable special tool Unterpulverversch spaung with the above parameters.
- the rail can be heated to an elevated temperature prior to applying the weld line. A controlled controlled cooling by reheating the already welded rail is also possible.
- a grinding process can create a flat surface of the partial surfaces formed by the welding path.
- a corrugated surface can also be produced by the grinding, in particular by corrugation parallel to the rail longitudinal direction.
- the inventive Rail is characterized in that it is produced by the method according to the invention. In particular, it is characterized in that the abovementioned alloying parts of the welding wire available from Fontargen and the welding powder are found in the alloy of the material layer resulting from the welding.
