Description

Steel rail is the main component of railway track. Its function is to guide the wheels of rolling stock to move forward, bear the huge pressure of the wheels, and transmit it to the sleepers. The rail must provide a continuous, smooth and least resistance rolling surface for the wheels.

Manufacturing Process of Rails:

Raw Matrials –Heating – High pressure water dephosphorization – Blooming – High pressure air Phosphorus removal-Planish-Sawing-Pre Bending-Air Cooling-Physical and Chemical Property testing-Straightening- UT flaw detection – Drilling and milling-Heat Treatment-Test Rating-Identification-Package-Fished Steel Rails.
