Q:What is the method to check the straightness of rail?
The measurement accuracy of the latter is up to 0.4 microns /1000 mm. Straightness measurement is mainly to measure the straightness error of cylinder and cone, the guideway of machine tools and other machines, and the straightness error of the workpiece's linear guide surface.
Q:How are the rail tracks worn?
Rail is the main component of railway track. Its function is to guide the wheel of the rolling stock, to bear the great pressure of the wheel and to deliver it to the sleeper. The rail must provide a continuous, smooth, and least resistant rolling surface for the wheel. In electrified railway or automatic block section, rail can also be used as track circuit.
Q:What is the main material of high speed rail?
High speed rail is mainly made of steel U75V, UIC700, UIC900A and U71Mn high manganese steel.
Q:U71Mn what does "U" mean in the rail?
With the increase of axle load and the increase of vehicle speed, the rail type of rail becomes more and more heavy, and the performance develops to high strength. In the manufacturing process, from hot rolling to full heat treatment after rolling.
Q:What are the contents of the rail approach?
If you are into the rail welding base, to the selection of rail (rail according to the different choices of different welding tasks), welding inspection (inspection of rail in rail transport process has no damage), before steel rail welding straightening (rail end bend straightening), rust before welding (rail end, rail top surface, bottom of rail welding, prepare welding is left).
Q:Why can the single phase of catenary be used? Why is rail used as loop without electricity?
Commonly used FireWire, relative to the earth, there is voltage, so people standing on the ground will feel electric shock, when standing on the insulating object, it will not get an electric shockIsolated 220V, standing on the ground and touching one of them has nothing to do with it
Q:What is the method of rail butt welding?
Common Rail Rail butt joint, generally use fishtail board connection.Seamless rail bonding in the factory under the conditions of general use of air pressure welding or contact welding, the advantage of this is that there are relatively few impurities inside the solder joint, rail more stable.
Q:Why is the railroad track free of expansion joints now?
One is the long rail itself under all temperature stress, will be locked in the long rail sleepers, which is due to temperature change and contraction, this method is applicable to all the year round temperature of similar areas, for example in the south of Chinese. In some temperature difference regions should take another methods, namely the long rail itself does not bear the temperature stress, and stress or regular bleeding stress to automatic bleeding, make the long rail with temperature rise and free shrinkage, at the time of laying also try to choose the optimum temperature of the rail laying, the expansion value in the minimum range, so that regardless of temperature rise or fall, the rail expansion always control at a minimum.
Q:What is the width of the rail grade 43kg/m?
The level of rail 43kg/m, then the cross-section size is 140 mm, the cross-sectional area is 114 square centimeters, theoretical weight is 70 kg.
Q:Why should there be a certain gap in the rail connection?
No, it's expansion and contractionMainly because the track is made of steel, it will heat up and contract cold.If you don't sew it, it will break in summer.But now the latest technology can be used in other ways to overcome the heat up cold contraction effect, as seamless.
