高生产率及大幅度地节约原材料是冷挤压的两大优点。但是,在现有的压力机吨位不够、或单位变形力超过现有技术水平所容许的范围,或欲消除冷挤压中金属流动时出现的某些缺陷时,也可以放弃冷挤压的部分优点,来得到在现有条件下所能获得的最佳效益。本文介绍的涡轮盘冷挤压工艺就是这样的例子之一。 High productivity and substantial savings in raw materials are two major advantages of cold extrusion. However, when the existing tonnage of presses is insufficient or the unit deformation force exceeds the range allowed by the state of the art, or some of the defects that occur when the metal flows in the cold extrusion are eliminated, the cold extrusion may be dispensed with Advantages, to get the best benefits available under the current conditions. This article describes the turbine disk cold extrusion process is one such example.
