Thermal forging is an important component in the thermal power generation industry, which needs to run for a long time in a high temperature environment. Therefore, the high temperature performance of thermal power forging materials has an important impact on its quality and safety. This paper will analyze and discuss the high temperature performance and application of thermal power forging materials, aiming at providing reference for improving the quality and safety of thermal power forging materials.
When selecting thermal power forging materials, it is necessary to consider its high temperature performance requirements, strength requirements, toughness requirements, corrosion resistance requirements, etc. Commonly used thermal power forging materials include carbon steel, alloy steel, stainless steel and so on. Carbon steel has good machinability and weldability, but poor oxidation resistance and corrosion resistance. Alloy steel on the basis of carbon steel added a certain amount of alloying elements, improve the strength and toughness of the material, but also improve the oxidation resistance and corrosion resistance; Stainless steel has excellent corrosion resistance and oxidation resistance, but the cost is higher.
Thermal power forging materials will undergo a series of physical and chemical changes at high temperature, including the evolution of structure, chemical composition changes, physical properties changes, etc. These changes can have an impact on the properties and safety of the material, so it is necessary to test and analyze the high temperature properties of the material. The commonly used high temperature performance test methods include thermogravimetric analysis, differential thermal analysis, high temperature tensile test and so on. Through these testing methods, the mechanical properties, thermal physical properties, chemical properties and other data can be obtained at different temperatures, so as to provide a basis for the selection and application of materials.
In practical applications, the appropriate materials need to be selected according to the specific working conditions and requirements of thermal power forgings. For example, in the environment of high temperature and pressure, it is necessary to choose alloy steel or stainless steel with excellent oxidation resistance and corrosion resistance; In the low temperature environment, it is necessary to choose carbon steel or low alloy steel with good toughness and low temperature performance.
In practical applications, the performance and safety of thermal power forging materials are affected by many factors, including working environment, working conditions, material quality and so on. In order to improve the quality and safety of thermal power forgings, the following measures need to be taken:
Control material quality: Select high-quality raw materials, and carry out strict chemical composition and mechanical properties testing to ensure that the material meets the relevant standards and requirements.
Optimize the production process: The use of advanced forging process and equipment, control the temperature, pressure, time and other parameters in the production process, to ensure that the product has excellent organization and performance.
Strengthen quality testing: carry out strict quality testing on the products produced, including appearance inspection, non-destructive testing, mechanical property testing, etc., to ensure that the products meet the relevant standards and requirements.
Regular maintenance and overhaul: Regular maintenance and overhaul of thermal power forgings in operation, timely detection and treatment of potential safety hazards, to ensure the safety and stability of equipment operation.
The high temperature performance and application of thermal power forging materials are important issues in the thermal power generation industry. When selecting and applying thermal power forging materials, it is necessary to consider its high temperature performance requirements, strength requirements, toughness requirements, corrosion resistance requirements, etc., and select the appropriate material according to the specific working conditions and requirements. In practical applications, it is necessary to take a variety of measures to improve the quality and safety of thermal power forgings, including controlling the quality of materials, optimizing the production process, strengthening the quality inspection, regular maintenance and overhaul. Through the implementation of these measures, it can ensure the safety and stability of thermal power forgings in a high temperature environment for a long time, and contribute to the sustainable development of the thermal power generation industry.
