Methods of Rail Reinforcement

Edit:Zongxiang Heavy Industry--Lucas Date:2020-02-14 01:09:06

Rail reinforcement methods can be roughly divided into two types:

1. Rail alloying, with simple production process, less investment, less energy consumption, overall strengthening of rail, uniform surface hardness and good weldability.steel rail China manufacturer

2. Heat treatment of carbon steel can also improve the strength and hardness of the steel rail. At the same time, it has good toughness, saves alloy and is suitable for mass production.

Production practice in metallurgical industry holds that if the steel grade is not changed, it is difficult to greatly improve the strength of carbon steel by heat treatment alone. Only by combining microalloying with heat treatment and supplementing each other can high-quality rails with higher strength, corresponding toughness, hardness and weldability be obtained.steel rail China manufacturer
