Introduction

Rail steel is the main component of railway track. According to the Chinese national standards and the standards of the Ministry of Metallurgical Industry, rails are divided into railway rails, light rails, conductive rails and crane rails. 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. In the electrified railway or automatic block section, the rail can also be used as a track circuit. Due to the simultaneous increase in train speed and weight, the user departments have put forward higher and higher requirements for the comprehensive performance of the rails, requiring the rails to develop toward heavy-duty, toughness, purity and high-precision.
