自由锻造所用工具和设备简单，通用性好，成本低。 同铸造毛坯相比，自由锻消除了缩孔、 缩松、气孔等缺陷，使毛坯具有更高的力学性能。锻件形状简单，操作灵活。
Free forging tools and equipment are simple， versatility and low cost. Compared with the casting blank， the free forging eliminates the defects such as shrinkage porosity， porosity， porosity and so on， so that the blank has higher mechanical properties. The shape of the forgings is simple and the operation is flexible.
锻造工艺过程一般由以下工序组成，即选取钢坯下料、加热、成形、锻后冷却。锻造的工艺方法有自由锻、模锻和胎膜锻。生产时，按锻件质量的大小，forging，生产批量的多少选择不同的锻造方法。
The forging process is generally of the following processes， namely，forging采购， the selection of high quality billets， heating， forming and cooling after forging. The forging process includes free forging， die forging and fetal membrane forging. When manufacturing， according to the size of forgings and the number of production batches， different forging methods are chosen.
锻造设备主要用于金属成形，所以又称为金属成形机床。锻造设备是通过对金属施加压力使之成形的，力大是其基本特点，故多为重型设备，设备上多设有安全防护装置，以保障设备和人身安全。
Forging equipment is mainly used for metal forming， so it is also called metal forming machine tool. Forging equipment is formed by exerting pressure on metal，forging价格， and its basic characteristics are large force. Therefore， most of the equipment are he**y equipment， and many safety protection devices are set up on the equipment to ensure the safety of the equipment and the body.
