GB QU70 Crane rail often uses U71Mn material. The carbon content of this steel is between 0.65%-0.76%, and the manganese content is between 1.10%-1.50%. Through appropriate heat treatment process, the rail can obtain good comprehensive mechanical properties and meet the use requirements of low noise and smooth operation. At the same time, the good toughness of U71Mn material also helps to absorb vibration energy and further reduce noise.
GB crane rails often undergo heat treatment processes such as quenching and tempering. Quenching can make the rail surface obtain high hardness and strength and improve wear resistance; tempering eliminates quenching stress, increases toughness and plasticity, and makes the rail have good comprehensive performance, which can withstand the load during the operation of the crane, reduce deformation and vibration, and thus achieve smooth operation.
Application scenarios
It is mainly used in the running tracks of various cranes, such as bridge cranes and gantry cranes in large factories, as well as cranes used for loading and unloading goods in ports and docks. Cranes in these places usually need to frequently lift heavy objects, and have high requirements for the bearing capacity, wear resistance and stability of the tracks. The QU70 low-noise and stable running national standard crane track can well meet these requirements, ensuring the safe and stable operation of the crane, while reducing the impact of noise on the working environment.
