The scorching sun is like a fire, and people are prone to heat stroke, but do you know? In the scorching summer, steel rail are also afraid of heat and will "heatstroke". The "heatstroke" of steel rail is terrible, and the track may bulge, endangering driving safety.
Today, the editor of China Coal will advise everyone on how to deal with steel rail "heatstroke"!
Data shows that the steel rail will change when the temperature of the rail rises. For every kilometer of rail and every 1 degree Celsius increase in temperature, the rail will stretch by 11.8 mm. Therefore, before the high temperature comes, it is necessary to relieve the stress in the weak section of the rail to make the rail stretch free Later, a partial "removal operation" was performed to meet the required temperature of the locked rail to prevent the track from expanding.
In order to prevent the track from expanding and causing the runway, the following aspects need to be done:
A, Adjust the track direction: adjust the track direction to make the geometric size meet the standard and reduce the lateral impact force of the track
B, Welded steel rail: enhance the smoothness of the track and reduce the impact force of the wheel set on the track
C, Fastening fasteners: re-tighten the fasteners to prevent the rails from shifting and crawling
D, Supplement uniform ballast: the ballast bed is evenly full, increasing the ballast bed resistance
In order to prevent "heatstroke" of the steel rail, it is necessary to use anti-expansion white cloth and cold water to cool the rail, wrap the anti-expansion white cloth on the rail, prepare for cooling, and then use cold water to spray water on the two rails from the outside to the inside at the same time to perform physical Cool down to prevent rail expansion.
China Coal Steel Rail manages track rails, steel rail cutting and processing, and has rich experience in processing and production, reliable quality, quality management, and trustworthy. If you have rail needs, we sincerely welcome your consultation!
