What is the material for railway track
Rail, rail, rail, etc. Used on a railroad and in conjunction with a switch, so that the train can walk without turning. The rails are usually made up of two balanced rails. The rails are fixed on the sleepers and the sleepers are ballast.A railroad track made of steel, capable of carrying greater weight than other materials. Sleepers are also called sleepers, grey pillows, or road sleepers. The function is to distribute the weight of the rails separately, and to keep the rails fixed, and to maintain track gauge.Generally speaking, the bottom of the track is paved with gravel. Ballast, also known as ballast, ballast or ballast, provides flexibility and drainage for the track. You can also shop in the rail base on the concrete (the bridge is quite common), or even embedded in concrete.
The main grades of domestic rails are U74, U71Mn, PD2, PD3 and BNbRE, of which PD2 is general carbon steel, SQ process, fully quenched rail, PD3 is high carbon micro vanadium low alloy rail, BNbRE is low alloy rail with niobium rare earth treatment.
The railway tracks are made of steel and can be divided into ordinary manganese containing rails, copper containing plain carbon steel rails, high silicon copper bearing steel rails, copper rails, manganese rails, silicon rails, etc..
