锻造比

本试验钢的锻造比以4-6为最佳。

Confining the forging ratio in four to six is the best choice for the steel in this experiment .

随着锻造比的增大，晶粒组织逐渐细化，锻件力学性能提高。

It could be concluded that following the forging ratio increasing , the grains refined gradually and the mechanical properties of forgings increased .

确定该合金最佳拔长锻造比为3～4。

The optimum drawing forging ratio for the alloy is 3 ~ 4 .

锻造比计算方法的探讨

Discussion of the Calculation Methods on Forging Ratio

LZ锻造的砧宽比、料宽比的临界值研究

Study on critical value of tool width ratio and blank width ratio of LZ forging

对宽板的最后成形锻造，料宽比是无法控制的。

It is unable to control the blank width ratio for a broad plate when it is compressed to take shape finally .

在径向锻造过程中，锻打压强、应力状态和材料流动形式受如锻造比、芯棒和锤头的形状、界面之间的摩擦系数和材料特性等各种参数的影响。

During the radial forging process , the forging pressure , stress state and material flows are influenced by forging rates , the die shape , the friction coefficient between surfaces and material property .
