在考虑锻造工艺时特别是最后一火的锻造时，应尽量避免在临界变形程度下进行，以免得到粗大晶粒组织。具体来说，高温下金属塑性好，forging价格，变形抗力小，应采用远大于临界变形程度的较大变形量锻造；低温修正时采用低于临界变形程度的小变形量进行局部修整。
When the forging process is considered， especially when the last fire is forged，forging厂家， the critical deformation should be avoided as far as ，沈阳forging， so as to avoid coarse grain structure. Concretely speaking， high temperature metal has good plasticity and small deformation resistance. We should adopt large deformation amount forging far greater than critical deformation degree. When low temperature correction is used， small deformation below critical deformation degree should be used for local trimming.
基本工序：自由锻造时，锻件的形状是通过一些基本变形工序将坯料逐步锻成的。自由锻造的基本工序有镦粗、拔长、冲孔、弯曲和切断等。
The basic process is: free forging，forging报价， the shape of forging is gradually formed by some basic deformation processes. The basic process of free forging is upsetting， drawing， punching， bending and cutting.
铝合金锻件的生产可在多种锻造设备上进行。锻锤可用于开式模锻和闭式模锻，其生产费用较低，锻打时需要控制好锤头的高度、打击力量和速度，因为在急剧变形过程中铝合金对应变速率敏感并具有放热性。机械压力机和螺旋压力机都广泛用于铝合金闭式模锻，适宜于生产中等尺寸、大体积和形状适度的铝锻件。
The production aluminum alloy forgings can be carried out on a variety of forging equipment. Hammer can be used for open die forging and closed die forging， the production cost is low， when the need to the forging hammer height， strike force and speed， because of the sharp deformation in the process Alloy strain rate sensitive and exothermic. Mechanical press and screw press are widely used in aluminum alloy closed die forging， which is suitable for the production of medium size， large volume and moderate shape aluminum forgings.
