Thermal power forging is an important component in thermal power generation equipment, its quality and performance directly affect the efficiency and safety of thermal power generation equipment. In the production process of thermal power forgings, reasonable process parameters play a crucial role in product quality. This paper analyzes the influence of process parameters on the quality of thermal power forging products from three aspects of temperature control, strength control and time control, and puts forward corresponding suggestions.
Influence of process parameters on product quality
Temperature control
Temperature is one of the important factors affecting product quality in the production process of thermal power forging. Reasonable temperature control can ensure that the forging has good plasticity and toughness in the forging process, to avoid overheating, overburning or cracking and other defects. At the same time, the appropriate temperature can also improve the mechanical properties of the material, such as hardness, strength and so on. Therefore, the heating temperature and holding time must be strictly controlled during the production process to ensure that the forgings are forged in the best condition.
Intensity control
In the production process of thermal power forgings, strength control is also one of the important factors affecting product quality. The appropriate strength can ensure that the forgings have good formability and internal quality during the forging process, and avoid excessive deformation or internal defects. At the same time, the appropriate strength can also improve the density and organizational uniformity of the material, thereby improving the mechanical properties and corrosion resistance of the forgings. Therefore, in the production process, the appropriate forging force and forging mode must be selected according to the material properties and forging requirements.
Time control
In the production process of thermal power forgings, time control is also one of the important factors affecting product quality. The appropriate holding time and cooling time can ensure that the forgings have good organizational structure and performance stability during the forging process, and avoid problems such as premature or late phase change, cracking or deformation. At the same time, the appropriate time can also improve the grain size and microstructure uniformity of the material, thereby improving the mechanical properties and corrosion resistance of the forgings. Therefore, in the production process, the appropriate holding time and cooling time must be selected according to the material properties and forging requirements.
When selecting process parameters, factors such as material properties, forging requirements and production conditions must be fully considered. Specifically, you can choose from the following aspects:
According to the material properties and forging requirements, the appropriate heating temperature and holding time are selected to ensure that the material has good plasticity and toughness in the forging process.
According to the strength and accuracy requirements, choose the appropriate forging strength and forging mode to ensure that the forging has good formability and internal quality during the forging process.
Considering the influence of cooling and holding time on the forging, the appropriate cooling method and cooling speed are selected to ensure that the forging has good organizational structure and performance stability during the forging process.
In order to avoid quality problems in the production of thermal power forgings, the following measures can be taken:
Strictly control the process parameters to ensure that the heating temperature, holding time, forging strength and cooling time and other parameters are within a reasonable range.
Check the equipment condition regularly to ensure the normal operation of the equipment in the production process to avoid product quality problems caused by equipment failure.
Establish quality files, timely correction and prevention of quality problems, and constantly improve the controllability of the production process and the consistency of product quality.
The technological parameters of thermal power forging are very important to the product quality. By reasonably controlling the process parameters such as heating temperature, holding time, forging strength and cooling time, it can be ensured that the forging has good organizational structure and performance stability in the forging process, so as to improve the quality and performance of the product. Therefore, the process parameters must be strictly controlled in the production process, equipment maintenance and quality management must be strengthened, and the controllability of the production process and the consistency of product quality must be continuously improved. Only in this way can the normal operation and safety of thermal power generation equipment be guaranteed.
