Introduction of 60kg Railway Heavy Rail
The heavy rail is a steel grade that produces a rail with a nominal weight greater than or equal to 30 kg/m. China mainly refers to the steel grade used for the production of heavy rails (including ballasts) from 60 kg/m to 75 kg/m. The heavy rail is to withstand the pressure, impact load and friction of the rolling stock, so it is required to have sufficient strength, hardness and certain toughness. To adapt to the needs of railway heavy-duty and high-speed, in addition to increasing the single weight of the heavy rail, it is also necessary to improve the overall performance. Higher toughness, wear resistance, crush resistance and brittle fracture resistance are required. The quality of the production process is strict. In addition to ensuring its chemical composition, it also requires testing of mechanical properties, drop weight test and acid etching low-fold tissue inspection.
