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，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，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, we need to carry out in the ventilation and purification environment. There are various kinds of forging tools, which are also intensive operati. 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.
机器锻造是自由锻造的主要方法，可锻造质量达到几百吨的大型锻件，这使得自由锻在重型机械制造中具有特别重要的作用。例如，水轮机主轴、多拐曲轴、大型连杆、重要的齿轮零件，在工作时都承受很大的载荷，常采用自由锻造方法生产毛坯，使其具有很高的力学性能.满足使用要求。在镦粗时，常用软衬垫镦粗或叠镦（用于锻薄饼形零件），以改善变形的不均匀性，防止产生表面裂纹。
Machine forging is the main method of free forging. It can forge large forgings with a quality of hundreds of t, which makes free forging play a very role in he***y machinery manufacturing. For example, the main shaft of a hydraulic turbine, a multi crank crankshaft, a large connecting rod, and important gear parts are subjected to he***y loads when they are working. Free forging is often used to produce blanks, so that they h***e high mechanical properties.
自由锻造是靠人工操作来控制锻件的形状和尺寸的，所以锻件精度低，加工余量大，劳动强度大，生产率也不高，因此它主要应用于单件、小批量生产。
Free forging is by manual operation to the shape and size of the forgings, so the precision of the forgings is low, the processing allowance is large, the labor intensity is big, and the productivity is not high. Therefore, it is mainly used in single piece and ***all batch production.
