With the development of modern industry, the requirements for material properties are increasing day by day. Among many materials, low-temperature steel is favored for its excellent low-temperature performance and is widely used in important fields such as aerospace and nuclear energy. However, how to effectively control the forging process parameters of low-temperature steel forgings to ensure their performance and quality has become an urgent problem to be solved in the industry.

 

一, the importance of low temperature steel forging process parameters

 

Forging is a processing method that causes plastic deformation of metal materials by applying pressure, and it is an important means to manufacture high-quality metal parts. In the forging process, the selection and control of parameters such as temperature, pressure and deformation speed directly determine the quality and performance of the forging. Especially for low-temperature steel forgings, the choice of forging process parameters is more critical, because the mechanical properties of low-temperature steel change significantly in the low-temperature environment, which requires high heat treatment in the forging process.

 

二. Analysis of forging process parameters of low-temperature steel forgings

 

1. Temperature control: low temperature steel forging temperature range is narrow, too high temperature will lead to coarse grain material, reduce material strength; However, too low temperature will cause the plasticity of the material to decrease and increase the difficulty of forging. Therefore, it is very important to choose the right forging temperature range.

2, the size of the pressure: the size of the forging pressure directly affects the change of the internal structure of the forging, thus affecting its mechanical properties. For low-temperature steel, the appropriate forging pressure can ensure that the forging has a good comprehensive performance.

3. Degree of deformation: A reasonable degree of deformation can optimize the microstructure of the material and improve its mechanical properties. However, excessive deformation may lead to cracks or other defects in the forging.

 

三. Determination of forging process parameters of low-temperature steel forgings

 

In order to obtain high performance low temperature steel forgings, it is necessary to determine the best forging process parameters by scientific method according to the specific application requirements and material characteristics. This usually involves the combination of experimental research and numerical simulation, through the test and analysis of the performance of forging under different conditions, gradually adjust and optimize the process parameters until the expected goal is reached.

 

四. Conclusion

 

The reasonable selection and precise control of forging process parameters of low-temperature steel forgings are of great significance to improve product quality and meet the needs of special working conditions. In the future, with the development of new material technology and the improvement of intelligent manufacturing level, the forging process of low-temperature steel forgings will develop in a more accurate and intelligent direction.
