镦粗是镦粗示意图使毛坯高度减小，横断面积增大的锻造工序。 镦粗工序主要用于锻造齿轮坯、圆饼类锻件。镦粗工序可以有效地改善坯料**，forging设备，减小力学性能的异向性。 镦粗与拔长的反复进行，可以改善高合金工具钢中碳化物的形态和分布状态。
Upsetting is the forging process that indicates that the blank height is reduced and the cross section area is increased. The upsetting process is mainly used for forging gear blanks and round cake forgings. The upsetting process can effectively improve the billet structure and reduce the anisotropy of mechanical properties. The morphology and distribution of carbides in high alloy tool steel can be improved by repeated upsetting and drawing.
在锻造时，金属的脆性杂质被打碎 ，丹东forging，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，forging生产厂家， 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.
自由锻造所用的工具简单，加工方法通用性强，生产准备周期短，因而应用较为广泛。自由锻分为手工锻造和机器锻造两种。手工锻造只能生产小型锻件，生产率也较低。
The tool used for free forging is simple，forging谁家好， the versatile and the production period is short， so it is widely used. Free forging is divided into two kinds: manual forging and machine Manual forging can only produce **all forgings， and the productivity is low.
