43 kg of heavy rail material has 50 Mn, U71Mn two kinds, length is 12,12.5 meters two kinds, the quality requirements in the production process strictly, in addition to guarantee its chemical composition, also requires testing of mechanical properties, including the drop test and acid corrosion macrostructure examination, etc.
Main Application
The heavy rail should bear the pressure, impact load and friction force of the locomotive, so it is required to have sufficient strength, hardness and certain toughness.Station line and special line generally lay 43kg/m rail.It is mainly used for 10-20 tons of driving, crane, crane and coal feeder.
