forging-圣霖国际【顾客至上】-forging生产厂家

自由锻造的设备分为锻锤和液压机两大类。生产中使用的锻锤有空气锤和蒸汽-空气锤，有些厂还使用结构简单，***少的弹簧锤、夹板锤、杠杆锤和钢丝锤等。

The equipment of free forging can be divided into two categories: forging hammer and hydraulic press. The forging hammers used in production are air hammer and steam-air hammer. Some factories also use spring hammer， splint hammer，forging， lever hammer and steel wire hammer with simple structure and low investment.

若因温度和变形程度选择不当而得到粗大晶粒时，forging谁家好，可利用热处理相变细化晶粒***，forging生产厂家，但对于热处理中不发生相变的钢种，如奥氏体钢，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.

由于热变形形成纤维***，会使金属的力学性能出现异向性，forging设备，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 directi*** is Rm. Re is not very different.
