等温模锻是六十年代末发展起来的锻造新工艺,运用这一新工艺可以生产出准净尺寸的产品。美伊利诺斯州理工学院研究所的有关专家认为,等温锻造在锻造技术中堪称突破。在普通的压力机或锤上精化锻件时,由于模具的温度较低,工件(特别是叶片部位)易于冷却,再加变形速率较高,变形抗力明显增加,这些都会阻碍金属在模具中的充填。为了进一步精化锻件,提高材料的利用率,减少机械加工工时,获得变形均匀的高质量的叶轮锻件
Isothermal die forging is the development of the new forging technology developed in the late sixties, the use of this new technology can produce quasi-net size of the product. Relevant experts from the Institute of Technology, Illinois Institute of Technology believe that isothermal forging is a breakthrough in forging technology. In normal presses or hammers, when the forging is refined, the workpieces (especially the vane parts) are easily cooled due to the low temperature of the mold, and the high deformation rate and the markedly increased deformation resistance all hinder the metal from forming in the mold Filling. In order to further refine the forgings, improve the utilization of the materials, reduce the machining time and obtain the high-quality impeller forging
