Reinforcement Method Of Heavy Steel Rail

Generally speaking, the heavier the GB standard steel rail, the lesser the degree of rail damage will be, and it is not easy to bend and deform. According to this problem, the following two ways of strengthening.

1. Heavy steel rail alloying, which has simple production process, low investment, low energy consumption, overall reinforcement of the rail, the uniform hardness of the surface layer and good weldability.

2. Heat treatment of carbon steel, this method can also improve the strength and hardness of the rail, while good toughness, save the alloy, suitable for mass production. The practice of metallurgical industry believes that if the steel is not changed, it is difficult to increase the strength by carbon steel alone. Only the combination of micro-alloy and heat treatment can complement each other to obtain higher strength. High-quality rails with corresponding toughness, hardness and weldability.
