Improvement of Mining machinery forgings material properties by forging process

1. Basic improvement of material properties by forging process
The forging process is to change the microstructure of metal materials by plastic deformation through high temperature heating and mechanical pressure. Compared with casting, the forging process can significantly improve the density of metals, reduce defects such as pores and cracks, and improve the uniformity of materials. This uniformity and high-density structure improve the strength, toughness and corrosion resistance of metals. In nuclear power projects, the optimization of forging process not only improves the basic mechanical properties of forging materials, but also enhances their adaptability in environments.

2. Optimize microstructure and improve the radiation resistance of materials
The equipment in nuclear power plants is exposed to radiation sources such as neutrons and gamma rays released by nuclear reactors for a long time. These radiations will have a certain impact on the lattice structure of metal materials, resulting in radiation hardening, embrittlement and other problems in metals. In order to ensure the stability of nuclear power plant equipment in radiation environment, the optimization of forging process is crucial to improve the radiation resistance of materials.

3. High-temperature forging and improvement of material properties
In nuclear power projects, equipment often needs to withstand extremely high temperatures and pressures, which places strict requirements on the performance of materials. Through high-temperature forging, metal materials undergo plastic deformation at high temperatures, which can significantly improve their mechanical properties and high-temperature resistance.

4. Improvement of material properties by precision forging process
Precision forging is to make metal materials more refined during the forging process by precisely controlling process parameters such as temperature, pressure, deformation rate, etc. This process can significantly improve the surface quality and dimensional accuracy of forgings, reduce the generation of defects, and enhance the overall performance of materials. Precision forging not only improves the radiation resistance of metals, but also improves their stability in high-temperature and high-pressure environments.

For key equipment components in nuclear power projects, precision forging can effectively reduce pores and microcracks in the material, ensure the uniformity and density of the metal structure, and thus improve its radiation resistance, corrosion resistance and high-temperature resistance. In particular, materials such as F91 and F92 can work efficiently and stably in nuclear power plants for a long time after precision forging, ensuring the safe operation of equipment.

5. Comprehensive improvement of the performance of Nuclear project forgings by forging technology
Through the application of advanced technologies such as precision forging and high temperature forging, the overall performance of Nuclear project forgings has been significantly improved. The forging process can not only improve the mechanical properties of the metal, but also improve its high temperature resistance, radiation resistance, corrosion resistance and other characteristics, thereby ensuring the long-term stable operation of nuclear power plant equipment under working conditions.

In practical applications, alloy steel materials such as A182 F91 and F92 are often used in key equipment of nuclear power plants, such as nuclear reactor pressure vessels, pipelines, steam generators and other components. By optimizing the forging process, these materials can maintain performance in complex environments such as high temperature, high pressure, and strong radiation, effectively ensuring the safety and reliability of nuclear power plants.
