Research and practice on cold resistance of locomotive track block forgings in low temperature environment

With the development of science and technology and the deepening of human’s extreme environmental challenges, cold resistance has become an indispensable performance index in many industrial fields. Locomotive track block forging is an important part of railway transportation system, its cold resistance is directly related to the safety and stability of railway transportation. Therefore, it is very important to study and practice the cold resistance performance of locomotive track block forgings in low temperature environment

In extremely cold areas, such as China’s northeast, northwest regions and northern Europe, Russia and other countries, winter temperatures often drop to tens of degrees below zero. In this low temperature environment, locomotive track block forging is easy to break due to cold and brittleness, which leads to serious safety accidents. Therefore, improving the cold resistance of locomotive track block forging is of great significance to ensure the safety and stability of railway transportation.

Low temperature brittleness analysis: In a low temperature environment, the brittleness of metal materials increases and it is easy to fracture. Therefore, the low temperature brittleness analysis of locomotive track block forging is an important premise to improve its cold resistance. By studying the stress-strain curves of the material at different temperatures, the brittleness behavior of the material at low temperature can be deeply understood, so as to provide a theoretical basis for improving the cold resistance.
Application of cold resistant alloy materials: Through the development of new cold resistant alloy materials, can effectively improve the cold resistance of locomotive track seat forging. For example, the use of materials such as nickel-based alloys or titanium alloys with excellent low-temperature toughness can effectively reduce the risk of brittle fracture while maintaining good mechanical properties.
Process optimization: Reasonable forging process can significantly improve the cold resistance of locomotive track base forgings. By optimizing the heat treatment process and adjusting the forging ratio, the structure of the material can be refined, its toughness and strength can be improved, and the cold resistance can be enhanced.

Under the guidance of theoretical research, the cold resistance of locomotive track block forgings can be effectively improved by applying new cold resistant alloy materials and optimizing technology in practice. In the process of practical application, we should pay attention to the collection and analysis of actual operation data, so as to evaluate the effect of improvement measures scientifically. In addition, safety performance testing should be carried out regularly to ensure that the locomotive track seat forging can maintain good operating condition under low temperature environment.

The research and practice of the cold resistance of locomotive track block forging under low temperature environment is an important subject. Through in-depth research on the application of low temperature brittleness, cold resistant alloy materials and process optimization, the cold resistant performance of locomotive track block forging can be effectively improved, which provides strong support for ensuring the safety and stability of railway transportation. In the future, with the continuous development of science and technology, we believe that we can develop more excellent cold-resistant materials and processes to further promote the development of railway transport.
