锻造生产加热设备和锻压设备不可少，这些设备释放大量热能，forging报价，需要我们在通风净化环境中进行。锻造工具种类繁多，也是密集型作业，要求每个技术人员都不能马虎，坚守自己的岗位，嘈杂的环境需要冷静的技师，forging哪家好，不能随意操作。

Forged production of heating equipment and forging equipment can not be less， these release a large amount of heat energy，forging， we need to carry out in the ventilation and purification environment. There are various kinds of forging tools， which are also intensive operations. Every technician is not allowed to be careless and stick to their. The noisy environment needs a cool technician and can not be arbitrarily operated.

自由锻都是以生产批量不大的锻件为主，采用锻锤、液压机等锻造设备对坯料进行成形加工，获得合格锻件。 自由锻的基本工序包括镦粗、拔长、冲孔、切割、弯曲、扭转、错移及锻接等。自由锻采取的都是热锻方式。

Free forging is in the production of small quantities of forgings， the forging， hydraulic press forging equipment is carried out on the blank forming process， obtain qualified forgings. The basic process of free forging including upsetting，forging价格， stretching， punching， cutting， bending， torsion， displacement and welding etc.. The free forging is all hot forging.

由于热变形形成纤维组织，会使金属的力学性能出现异向性，即纵向力学性能指标中的A，Z，Ak比横向相应的指标大得多，两个方向上的强度Rm。Re差别不大。

Due to the formation of fibrous microstructure by thermal deformation， the mechanical properties of metals will be different. That is， A， Z and Ak in longitudinal mechanical properties are much larger than those itransverse direction， and the strength in two directions is Rm. Re is not very different.
