通过对抛丸器叶片的受力分析和失效分析，论述了影响叶片寿命的主要因素，并针对这些主要因素对叶片的化学成分、铸造工艺和热处理工艺进行了分析研究。装机试验证明，新的叶片寿命达到500h以上。
Through the analysis of the force and failure analysis of the blade, the main factors that affect the life of the blade are discussed, and the chemical composition, casting technology and heat treatment process of the blade are analyzed according to these main factors. Installed test proved that the new blade life of 500h or more.
