4Cr5W2VSi是目前广泛采用的锻模材料。在锻模设计中,由于预锻坯叶身的变形程度较小,使终锻模的寿命很短,特别是一模三槽布局的锻模寿命更短,这不仅影响了叶片的质量,而且造成了严重的经济浪费。经过长期实践和理论研究,采用了增大预锻坯叶身变形程度的设计方案,使这一技术课题获得了较好的解决。一、原版整流叶片锻模的寿命 4Cr5W2VSi is currently used forging die material. In forging design, because of the deformation of the preform body is small, so that the life of the final forging die is very short, especially in a three-slot die layout die life shorter, which not only affects the quality of the blade, and Caused a serious economic waste. After long-term practice and theoretical research, the design scheme of increasing the deformation degree of the preform body is adopted, which makes this technical subject get a better solution. First, the original rectifier blade forging life
