Application of steel rails in railways

Rail, the full name of railway track, is a railway facility. Used on railways and cooperates with switches and switches to allow trains to walk without turning. Rail tracks usually consist of two balanced rails. The rails are fixed on the sleepers, and the ballast is under the sleepers.

Early rails were made of thin iron pieces nailed to wooden rails. But the load-bearing capacity of such rails is very low, so although the construction cost is low, it is not cost-effective in the long run. Steel rail for sale.

Later, the railway began to use steel rails. After decades of improvement, the material used was changed to steel, and the quality of the steel was greatly improved. Rails used on railways have to withstand enormous pressure, so high-quality steel is required. Railway rails have higher steel requirements than any other application. The same small flaws may not cause any problems if they appear in the steel bars used in buildings; but if they appear in the railway rails, they can cause the rails to break at any time and cause the train to derail. Rails are not cheap and make up a considerable part of railroad costs. Steel rail for sale.

The section of the rail used in modern times is in the shape of "I", which is divided into the rail head contacting the wheel, the middle rail waist and the bottom rail bottom. Different routes have different requirements on the strength, stability and wear resistance of the rail. Therefore, the rails also have different specifications. Which one should be used on a route, economic and technical factors need to be considered. Steel rail for sale.
