锻比作为一个宏观指标,只代表锻件所经历的截面形状变化。合理控制砧宽比、压下量等对内部变形起决定性作用的参数,可以在小锻比条件下生产合格产品。
鍛比作為一箇宏觀指標,隻代錶鍛件所經歷的截麵形狀變化。閤理控製砧寬比、壓下量等對內部變形起決定性作用的參數,可以在小鍛比條件下生產閤格產品。

The forging ratio is just a macro indicator and only shows the shape change of the forging cross section. The determinant parameters such as the anvil width ratio and reduction which influence on the inner deformation will be controlled and the acceptable products will be obtained with minimum forging ratio.
