Heavy rail is an important product in the rail equipment market today, the basic scope of heavy rail is also widely used, it is the existence of many enterprise customers’ trust and recognition, the maintenance skills of all aspects of heavy rail in production and use are also mastered by our company, the following is the solution to the phenomenon of thermal expansion and contraction in heavy rail production.

First, the “locking rail temperature” should be determined according to the local climatic conditions, when the rail is locked, the seamless line is fixed on the sleeper and the base bed with fasteners; the fixing force is greater than the force of thermal expansion and contraction; the rail is not allowed to expand and contract, long rails are welded by welding, to be ground, and then polished.

The fastening method of the fastener is to replace the spring fastener with a spring fastener(also called a spring fastener), and the heavy rail is tightly fastened to the sleeper, forcibly digesting the energy generated by the thermal expansion and contraction, it is necessary to make a few holes in the rail of the heavy rail to release the energy generated by the thermal expansion and contraction within a certain distance, and retain the heavy rail joint within a certain distance(about 1500m) to assist in releasing the thermal expansion and contraction, energy to solve the problem of thermal expansion and contraction of rails.

According to the above methods and techniques, the thermal expansion and contraction of the heavy rail can be reasonably and effectively solved, thereby improving the installation and use of the equipment, if you want to purchase a satisfactory heavy rail product, welcome to call us.
