锻造规格值得信赖 圣霖国际创新发展

由于热变形形成纤维***，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 directi is Rm. Re is not very different.

定期对设备进行***，所有的操作者工作之前必须带好防护用具。在进行锻造作业时，几个操作者之间要集中精力，互相配合，躲开***方向，选择相对安全的位置。

Maintenance of equipment on a regular basis, and all operators must take protective equipment before working. In the process of forging, several operators should their energy, cooperate with each other, ***oid the dangerous direction, and choose a relatively safe.

不知道听到工艺两个字的时候我们更多的想到的是什么?我想很多人对工艺的追求大多体现在对一些艺术品上面。完全镦粗是将坯料竖直放在砧面上，在上砧的锤击下，使坯料产生高度减小，横截面积增大的塑性变形。其实不仅仅是艺术品对工艺的要求非常高。在我们的机械领域对工艺也是精益求精的，因为只有高超的工艺才能制造出更的产品，就比如说大口径法兰对它的工艺要求也是很高的。

I don't know what we think about more when we hear the two of the craft?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。 I think a lot of people's pursuit of the craft is mostly on some of the works of art. In fact, not only is the art of art demanding very high technology. In our field of machinery, we also strive for improvement in technology, because only superb technology can make more perfect products, for example, large diameter flanges require high technological requirements for them.

随着电动机的发明，十九世纪末出现了以电为动力的机械压力机和空气锤，并获得迅速发展。锻件是金属被施加压力，通过塑性变形塑造要求的形状或合适的压缩力的物件。第二次以来，七十五万千牛的模锻水压机、一千五百千焦的对六万千牛的板料冲压压力机、十六万千牛的热模锻压力机等重型锻压机械，和一些自动冷镦机相继问世，形成了门类齐全的锻造机械体系。

With the invention of motor, the mechanical press and air hammer powered by electricity appeared at the end of nineteenth Century, and developed rapidly. Since the Second World War, the forging water press, one thousand and five hundred thousand char, the punching press of Liu Wanqian cattle, the hot forging press of sixteen thousand thousand cattle, and some automatic cold heading machines h***e come out in succession, forming a complete system of forging machinery.
