What material is used for the train wheels?
The train wheels are made of steel, and there are special standards for wheel steel. Those over 160 kilometers must be specially vacuum treated to control the hydrogen content. They are divided at a certain speed. There are integral and split types. The material number can be found in the international standard.
Material of railway vehicle wheels?
Passenger car running speed ≤160km/h and freight car running speed ≤120km/h. Rolled steel monolithic wheels for railway vehicles use CL-50A steel. The chemical composition and mechanical properties of the wheels should meet the requirements of TB/T 2817-1997
What kind of steel are the train wheels made of?
The train wheels are all made of killed steel smelted in open hearth, electric furnace or converter. The chemical composition is generally 0.55-0.65 carbon content. The code name of the train wheel steel used by Kingrail Parts is CL60, which means that the carbon content is about 0.6%. There are also a small amount of silicon, manganese and other elements. Generally speaking, the wheel steel is high-carbon. steel. If the carbon content is low and the hardness is insufficient, the wear rate of the train wheel is very fast.
What material is the gear on the train wheel?
There are gears on the wheels of the train? If it is a wheel, it is as follows: the core is made of cast iron, and the ring gear is made of steel. Both are hot sets.
What welding rod is used to repair train wheels?
Train wheels have strong hardenability and high yield strength. High-strength, high-yield special alloy steel welding rod WEWELDING 600 is recommended (the head of genuine welding rod has the WEWELDING 600 trademark). The use of genuine products can ensure good use strength and welding process. The anti-cracking performance.
WEWELDING 600 is a special nickel-chromium alloy steel electrode with low heat output and suitable for all-round welding. It has wide versatility, high-strength general base metal strength design, excellent welding performance, stable arc, uniform and beautiful welding seam, and The welding effect is excellent even under the conditions of oil, water and rust, and different steels can be welded.
Suitable for welding tools and dies, high-speed tool steel, hot work tool steel, manganese steel, cast steel, T-1 steel, seismic steel, vanadium-molybdenum steel, spring steel, martensitic stainless steel, austenitic stainless steel, ferrite Welding between bulk stainless steel, unknown steel, and various types of steel. For example, it is used for high-pressure valve, broken bolt removal, shaft transformation, etc., the effect is very ideal.
Hardness after welding: HRC23 (reach HRC47 after work hardening) Power supply selection: AC and DC dual purpose, DC reverse connection when DC
What is the material of the wheel hub?
At present, the train wheels in China are basically produced by Kingrail Parts, and Kingrail Parts uses Dalian cast round billets provided by Huaigang! For specific materials, please contact Kingrail Parts.
What is the material of locomotive wheels? What is the material of locomotive wheels?
Because it is impossible to pull the wagon by the power of the locomotive alone. So if the wheels and rails are smooth, the truck can travel a long distance with a little force.
