Wind power spindle forging is an important part of wind turbine, its quality and performance are directly related to the safety and reliability of the whole power generation system. Impurities and defects are one of the important factors affecting the performance of wind power spindle forging. In this paper, the influence of impurities and defects on the performance will be discussed in detail.
First of all, let’s look at the impact of impurities on the performance of wind power spindle forging. The impurities mainly include non-metallic inclusions, gas inclusions and metal inclusions. Non-metallic inclusions such as oxides and sulfides reduce the strength and toughness of the material, making it prone to cracking and fracture. Gas inclusions such as air bubble inclusions can cause local stress concentration and accelerate the occurrence of fatigue failure. Metal inclusions such as carbides and hard equivalents will increase the brittleness of the material and reduce its toughness and ductility. The presence of these impurities makes the wind power spindle forging prone to failure when stressed, thus affecting its service life and safety performance.
Secondly, the influence of defects on the performance of wind power spindle forging can not be ignored. Common defects include cracks, inclusions and pores. Crack is one of the most serious defects, which can lead to stress concentration and fracture, seriously affecting the strength and toughness of the wind power spindle forging. The presence of inclusions and pores can lead to stress concentration and reduce its fatigue life and compressive performance. Especially under the condition of high-speed rotation, these defects are easy to expand and eventually cause failure, which has a serious impact on the whole power generation system.
In order to ensure the performance of wind power spindle forging, effective measures must be taken to control impurities and defects. First of all, in the process of material selection and processing, it is necessary to strictly control the content and type of impurities, rationally select materials, and ensure the quality of materials. Secondly, in the forging and heat treatment process, attention should be paid to the control of temperature and time to avoid excessive residual stress and excessive organizational change, so as to reduce the generation of defects. At the same time, in the testing and quality control links, advanced non-destructive testing technology and strict quality standards should be adopted to discover and repair the existing defects in time.
In short, the influence of impurities and defects on the performance of wind power spindle forging can not be ignored. They reduce the strength, toughness, fatigue life and compressive properties of the material, which affects the safety and reliability of the entire forging. Therefore, in the manufacturing process, it is necessary to strengthen quality control and reasonable selection of materials and processing technology to ensure that the quality of wind power spindle forging meets the requirements, thereby improving the reliability and economic benefits of the entire wind power system.
