通过锻造能消除金属在冶炼过程中产生的铸态疏松等缺陷，优化微观***结构，同时由于保存了完整的金属流线，锻件的机械性能一般优于同样材料的铸件。

Forging can eliminate the defects such as casting porosity and so on during the ***elting process, and optimize the microstructure. At the same time, because of the intact metal flow line, the mechanical properties of the forgings are generally better than those of the same materials.

在锻造时，金属的脆性杂质被打碎 ，顺着金属主要伸长方向呈碎粒状或链状分布；塑性杂质随着金属变形沿主要伸长方向呈带状分布 ， 这样热锻后的金属***就具有一定的方向性。

When forging, the brittle metal impurities to be broken down, the main direction of elongation is like particles of metal or plastic chain distribution; impurities with metal deformation distributed along the main direction of elongation, so after hot forging metal organization has certain direction.

锻造是指把加热后的金属材料锻制成各种形状的工具、机械零件或毛坯。锻造过程中要对这些滚烫的金属坯料进行各种加工，因此加工过程中高温、、振动和噪声是避免不了的。所以锻造过程安全防护很重要。

Forging is a tool, mechanical part, or blank that is forged from a heated metal material to a variety of shapes. In the process of forging, these hot metal billets should be processed, so high temperature, dust, vibration and noise can not be ***oided during the process. Therefore, the safety protection of the forging process is very important.

自由锻造的设备分为锻锤和液压机两大类。生产中使用的锻锤有空气锤和蒸汽-空气锤，有些厂还使用结构简单，***少的弹簧锤、夹板锤、杠杆锤和钢丝锤等。

The equipment of free forging can be divided into two categories: forging hammer and hydraulic press. The forging hammers used in production are air hammer and steam-air hammer. Some factories also use spring hammer, splint hammer, lever hammer and steel wire hammer with simple structure and low investment.
