How to use the forging process to improve the life of bearing forgings?

Forging process is one of the key steps to prolong the life of bearing forgings. The following are some ways to use the forging process to improve the life of bearing forgings:

Optimization of forging process parameters: By adjusting forging process parameters, such as deformation, deformation speed and temperature, the grain size and mechanical properties of bearing forgings can be controlled, thereby improving their durability and fatigue strength.

Fine grain structure: By controlling the deformation amount and temperature in the forging process, the dynamic recrystallization and grain refinement of the steel can be promoted to form a more uniform and fine grain structure, thereby improving the strength and toughness of the bearing forgings.

Elimination of internal defects: The forging process can effectively eliminate internal defects in the steel, such as cracks, inclusions and holes. These defects can reduce the performance and life of bearing forgings, so eliminating them can improve the quality and durability of bearing forgings.

Increase the fiber structure: by rationally arranging the forging process, the fiber structure content in the steel can be increased. Fiber structure can improve the strength and toughness of steel, thereby improving the life of bearing forgings.

Surface strengthening treatment: After forging is completed, surface strengthening treatment can be carried out on bearing forgings, such as shot peening, rolling and carburizing. These treatments can increase the surface hardness and wear resistance of bearing forgings, thereby improving their life.

Reasonable heat treatment process: Heat treatment process is also an important step to improve the life of bearing forgings. By adjusting the heat treatment process parameters, the phase change process and microstructure of steel can be controlled, and the hardness and wear resistance can be improved.

In short, the use of forging process to improve the life of bearing forgings needs to consider a number of factors, including raw material quality, forging equipment, process parameters, heat treatment process and so on. By continuously optimizing the process flow and technical parameters, high quality and high performance bearing forgings can be manufactured, and their durability and fatigue life can be improved.
