自由锻生产率低，加工余量大，forging谁家好，但工具简单，通用性大，故被广泛用于锻造形状较简单的单件、小批生产的锻件。自由锻设备有空气锤、蒸汽-空气锤和水压机等，分别适合小、中和大型锻件的生产。
Free forging has many advantages such as low productivity， large machining allowance， but simple tool and versatility. So it is widely used for forging single piece and **all batch forgings with simpler shape. The free forging equipments include air hammer， steam air hammer and hydraulic press， etc.，forging厂家， which are suitable for the production of **all and medium he**y forgings，forging厂商， respectively.
镦粗 镦粗是对原坯料沿轴向锻打，使其高度减低、横截面增大的操作过程。这种工序常用于锻造齿轮坯和其他圆盘形类锻件。镦粗分为全部镦粗和局部锻粗两种。
Upsetting and upsetting is the process of forging the original billet along the axis， reducing its height and increasing its cross section. This process is usually used to forge gear blanks and other disc shaped forgings. The upsetting is divided into two kinds of upsetting and local forgings.
若因温度和变形程度选择不当而得到粗大晶粒时，可利用热处理相变细化晶粒**，但对于热处理中不发生相变的钢种，如奥氏体钢，白山forging，就必须在锻造过程中获得细小而均匀的晶粒**，因此对这样的材料在锻造时须加倍注意。
If the temperature and degree of deformation and improper selection of coarse grains， the grain refinement phase change heat treatment， but for the steel phase transition does not occur in the heat treatment， such as austenitic steel， it must be in the forging process h**e fine and uniform grains， so this kind of material in the forging must pay more attention to.
