Thermal power forging is an important component in thermal power generation industry, its quality and performance directly affect the operating efficiency and safety of thermal power generation equipment. With the adjustment of energy structure and the growth of power demand, the quality requirements of thermal power forgings are also increasing. In order to meet the higher requirements of use, the application and development of new materials has become the focus of thermal power forging manufacturing. This paper will analyze and discuss the application and development trend of new materials in the production of thermal power forgings.
In the production of thermal power forgings, choosing the right material is the key to improve product quality and performance. With the continuous development of science and technology, more and more new materials have been applied to the manufacture of thermal power forgings.
High strength alloy steel
High strength alloy steel is a kind of steel with excellent mechanical properties and wear resistance, which is widely used in the manufacture of thermal power forgings. For example, CrMo steel, CrNiMo steel and other high-strength alloy steels have been widely used in the manufacture of thermal power forgings.
Wear-resistant material
Wear-resistant materials also play an important role in the manufacture of thermal power forgings. For example, wear-resistant materials such as high-manganese steel, wear-resistant cast iron and wear-resistant alloy steel are widely used in the manufacture of wear-resistant parts such as coal mills and crushers.
Corrosion-resistant material
In the manufacture of thermal power forgings, corrosion resistant materials are more and more widely used. For example, corrosion resistant materials such as stainless steel and duplex steel are used to manufacture parts with corrosive media, such as those in flue gas desulfurization systems.
The production process of thermal power forging includes forging, heat treatment, processing and other links. In the application of new materials, the choice of process flow has a critical impact on product performance and cost.
Forging technology
Forging process is one of the important factors affecting the performance of thermal power forgings. The proper forging process can improve the density and mechanical properties of the material and reduce the defects. For example, the isothermal forging process can effectively reduce the deformation resistance and crack tendency of the material, and improve the formability and mechanical properties of the material.
Heat treatment process
Heat treatment process is another important factor affecting the performance of thermal power forgings. Through reasonable heat treatment process, the structure of the material can be adjusted and the mechanical properties and wear resistance of the material can be improved. For example, the use of quenching + tempering heat treatment process can improve the hardness and wear resistance of the material, while maintaining good toughness.
Processing technology
Processing technology is the last link that affects the performance and cost of thermal power forging. The use of advanced processing technology and equipment can improve the utilization rate of materials and processing efficiency, and reduce production costs. For example, the use of CNC machining technology can achieve efficient and accurate machining, reducing material waste and processing time.
With the continuous development of science and technology and the improvement of environmental protection requirements, the application and development of new materials in the field of thermal power forging manufacturing in the future will show the following trends:
Development and application of new wear-resistant materials
With the increase of the running time and load of thermal power generation equipment, the requirements for the wear resistance of thermal power forgings are also increasing. In the future, more new wear-resistant materials will be developed and applied, such as nano-wear-resistant materials and ceramic wear-resistant materials.
Application and development of environmental protection materials
With the improvement of environmental awareness and the implementation of environmental protection policies, more environmentally friendly materials will be applied to the manufacturing of thermal power forgings in the future, such as biodegradable materials and low-pollution materials.
Application and development of digital and intelligent manufacturing technology
Digital and intelligent manufacturing technology can improve production efficiency, reduce production costs and improve product quality. In the future, more digital and intelligent manufacturing technologies will be applied to the manufacturing of thermal power forgings, such as industrial Internet technology and artificial intelligence technology.
This paper analyzes the application and development trend of new materials in the production of thermal power forgings, and points out that the future application and development of new materials will show the development and application of new wear-resistant materials, environmental protection materials and digital and intelligent manufacturing technology. In order to cope with future challenges and opportunities, it is recommended that thermal power forging manufacturing enterprises strengthen technological innovation and equipment update, actively research and development and application of new materials and new technologies, improve product quality and production efficiency, reduce production costs and environmental pressure, and enhance the core competitiveness of enterprises and market share.
