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.
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-city railway operation, Zhou Qingyue and others suggested that the rail grinding cycle of China's high-speed railway should be re-grind every 30~50mt, take the upper limit of the ballastless track, and take the ballastless track from the line. Take it off. When the disease is temporarily found to affect the train operation, the grinding operation should be carried out as soon as possible.
