锻造件的锻造通常是在热状态下进行的

锻造件的锻造通常是在热状态下进行的,所以锻造件锻造其实就是一个金属塑性变形加工热态应力过程。通常来说,我们会以金属成型及其抗变形能力这两个指标来考虑锻造件的好坏。
The forging of forged parts is usually carried out in a hot state, so forging of forged parts is actually a process of metal plastic deformation and hot stress processing. Generally speaking, we consider the quality of forged parts based on two indicators: metal forming and its resistance to deformation.
对于锻造件来说,影响其可锻性的第一个因纤维 驱鸟设备 保定通风管道 塑料土工格栅 检查井模具 流水槽模具 锻造厂家 华尔街铜牛素是它的材料,一般纯金属会优于合金,合金钢优于高低碳高合金钢。有组织使用金属锻件,个别组织比组织铸造的柱状结构,粗粒结构和晶界偏聚或共晶体结构,将使锻造的延性很差。
For forged parts, the first factor affecting their malleability is their material. Generally, pure metals are superior to alloys, and alloy steel is superior to high and low carbon high alloy steel. If the metal forgings are used in a organized way, the columnar structure, coarse grain structure, grain boundary segregation or Cocrystal structure of individual structure casting will make the ductility of forging very poor.
此外应考虑锻造厂加工条件,比如说锻造件锻造时的温度,随着温度的升高可以提高延展性的金属;一旦当温度接近熔点时,它会引起燃烧,锻造而成,大幅降低了。
In addition, the processing conditions of the forging plant should be considered, such as the temperature during forging of forged parts, which can improve the ductility of metals as the temperature increases; Once the temperature approaches the melting point, it will cause combustion, forging, and greatly reducing.
还有就是锻造速度,一方面随着变形速度的增加,回复与再结晶过程太晚了,不能消除加工硬化,所以减少形状,阻力增大,延性很差。随着变形程度的增加率另一方面,产生的热量,是塑造金属增加,电阻降低,改善延性。
Another issue is the forging speed. On the one hand, as the deformation speed increases, the recovery and recrystallization process becomes too late to eliminate work hardening, resulting in reduced shape, increased resistance, and poor ductility. As the degree of deformation increases, on the other hand, the heat generated increases the amount of metal molded, reduces resistance, and improves ductility.
