I don’t know if you were curious about the gravel under the rails when you were a child. Maybe you don’t even know the truth even now, so let’s reveal the secret today. We know that the quality of the train is very large. The rails and sleepers are responsible for the weight of the train when it passes. When the train passes through the rails, the rails will undergo certain deformation and generate vibrations. Under such load, the rails and sleepers will easily fall into the ground. Heavy Steel Rail At the same time, the weather conditions such as heavy rain or insolation will have an impact. Thermal expansion and contraction will also deform the sleepers, and ground vibrations will also change the position of the train railway. Therefore, it is not easy to maintain the stability of the railway. In addition, the friction between the two trains will cause huge noise when the train is running on the rail joints. The impact caused by the train rail and the rail seam damages

Find here details of  12m Heavy Steel Rail  on our website. Today we would like to talk a bout the grinding cycle of the rail. The rail grinding cycle refers to the measurement basis of the rail grinding time interval, which needs to be determined according to the line condition and maintenance purpose. The influence of different lines on train running stability, vibration and noise is different, and the grinding cycle is also different. Steel Rail At present, the setting of the rail grinding cycle in China mainly depends on the field experience of rail grinding. The development rule of rail disease is not used to guide the setting of the rail grinding cycle. Before the opening of the Beijing-Shanghai high-speed railway, the  Steel Rail  was pre-polished by high-speed grinding trains. After the opening, the precautions were polished twice a year and adjusted according to the regional passenger traffic. According to the tracking observations of the Beijing-Tianjin inter-c

Find here details of  China Standard Steel Rail  on our website. Today we would like to talk about what are the standards for long rail welding. China Standard Steel Rail Rail welding is an important part of railway construction. Its quality directly determines the overall quality of the rail. Therefore, the welding of rails is generally valued during construction. Then, what are the precautions when welding long rails?  China Steel Crane Rail Manufacturer  would like to tell you. 1. The steel rail to be welded shall comply with the relevant technical conditions of the new line railway rail. The welding of the base rail shall be contact welding. The welding equipment operators must undergo professional training, be familiar with the quality standards of the rail welding head, and pass the examination of the relevant departments and obtain the operation. Certificate of conformity. 2. The operator must strictly implement the operation rules of the welding equipment, an
