How To Slow The Steel Track Contact Fatigue Damage?

图片
The  Steel Track  is designed to guide the wheels of the vehicle forward and withstand the enormous pressure of the wheels, which must provide a continuous, smooth and least resistant rolling surface for the wheels. In use, the rails are often subject to wear and tear, and the good rails let you know the contact fatigue damage of the rails. The rail contact fatigue damage can be roughly divided into three stages: Steel Track 1. The change of the shape of the rail tread, the unevenness of the rail tread, and the saddle-shaped wear at the weld will increase the impact of the wheel on the rail. 2. The contact fatigue of the rail joint is formed because the fatigue strength of the metal contact is insufficient. When the maximum shear stress point exceeds the shear yield limit, the point becomes a plastic region. 3. The destruction of the metal on the surface of the rail. Due to the cold work hardening of the metal, the hardness of the working surface of the rail hea...

Two Reinforcement Methods Are Available For Heavy Rails

Generally speaking, the heavier the rail, the lesser the degree of rail damage will be, and it will not be easily bent and deformed. For example,  43kg Steel Rail  is not easy to bent. According to this problem,  China Standard Heavy Steel Rail Manufacturer  has the following two ways of strengthening to be shared with you. China Standard Heavy Steel Rail Manufacturer 1. The alloying of the rails has simple production process, low investment, low energy consumption, overall reinforcement of the rails, uniform hardness of the surface layer and good weld ability. 2. Heat treatment of carbon steel, this method can also improve the strength and hardness of the rail, and at the same time, the toughness is good, the alloy is saved, and it is 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 t...
