Thermal power forging is an important component in thermal power generation equipment, its quality and performance directly affect the safety and efficiency of thermal power generation equipment. With the continuous development of science and technology, the application of new materials in thermal power forging is more and more extensive, which is of great significance to improve product quality and production efficiency. In this paper, the application scenario and practical effect of the new material preparation technology in the manufacture of thermal power forgings are discussed.
At present, the new materials in the manufacture of thermal power forgings mainly include high-strength steel, wear-resistant steel, corrosion-resistant steel and so on. The preparation technology of these new materials mainly includes smelting, continuous casting, forging, heat treatment and so on. In smelting, the use of vacuum smelting, electroslag remelting and other technologies can improve the purity of materials and microstructure uniformity. In the aspect of continuous casting, the density and microstructure of materials can be improved by continuous casting, electromagnetic stirring and other technologies. In forging, isothermal forging, hot die forging and other technologies can improve the formability and mechanical properties of materials. In terms of heat treatment, the use of quenching, tempering, surface strengthening treatment and other technologies can improve the structure and performance of the material, improve the wear resistance, corrosion resistance and fatigue strength of the material.
In the manufacture of thermal power forgings, it is of great significance to select suitable materials for improving product quality and production efficiency. When selecting materials, it is necessary to consider the chemical composition, mechanical properties, wear resistance, corrosion resistance and other requirements of the material. For example, for parts subjected to high stress and wear, high-strength and wear-resistant steels can be selected; For parts that withstand high temperatures and corrosion, corrosion resistant and oxidation resistant steels can be selected. In addition, it is also necessary to consider the cost of materials and production processes and other factors to choose cost-effective materials.
In the manufacture of thermal power forgings, the practice of preparation technology is of great significance to ensure product quality and production efficiency. The following describes the two preparation process practices:
Isothermal forging process: Isothermal forging process is an advanced forging technology that can forge materials at a constant temperature and strain rate. The use of isothermal forging process can reduce the deformation resistance and energy consumption of the material, and improve the formability and mechanical properties of the material. In the manufacture of thermal power forgings, isothermal forging process can be applied to the production of large forgings and complex forgings.
Surface strengthening process: Surface strengthening process is a technology to improve the surface properties of materials, which can form a strengthening layer on the surface of materials by spraying, laser cladding, ion implantation and other methods. The surface strengthening process can improve the wear resistance, corrosion resistance and fatigue strength of the material, and extend the service life of the equipment. In the manufacture of thermal power forgings, surface strengthening process can be applied to the production of wear-resistant parts and corrosion-resistant parts.
In the manufacture of thermal power forgings, quality control is of great significance to ensure product quality and production efficiency. Two quality control measures are described below:
Raw material inspection: strict inspection and control of raw materials to ensure that the quality and performance of raw materials meet the requirements. Raw materials can be inspected by chemical composition analysis, mechanical properties testing, metallographic structure observation and other methods.
Product testing: strict testing and evaluation of products to ensure that product quality and performance meet the requirements. Products can be tested by non-destructive testing, mechanical property testing, metallographic structure observation and other methods.
In the manufacture of thermal power forgings, the benefit evaluation of new material preparation technology is of great significance to evaluate the feasibility and effectiveness of the technology. The following are two methods for evaluating benefits:
Cost-benefit analysis: Analyze and compare the costs and benefits of new material preparation technology, and evaluate the economic benefits and return on investment of the technology. Methods such as cost estimation and market research can be used for analysis.
Performance testing and comparison: the performance of new materials and traditional materials are tested and compared to evaluate the performance advantages and application potential of new materials. It can be tested and compared by mechanical properties test, wear resistance test, corrosion resistance test and other methods.
In this paper, the preparation technology and practice of new materials in the manufacture of thermal power forgings are studied. Through the analysis of the research status of the new material preparation technology, material selection, preparation process practice, quality control and benefit evaluation, it is shown that the new material preparation technology has a wide range of application prospects and practical value in thermal power forging manufacturing. Future research directions can include further improving the new material preparation technology, improving the performance and stability of materials, reducing costs and expanding the scope of application.
