forging厂家 圣霖国际【用心服务】 沈阳forging

锻造工艺过程一般由以下工序组成，即选取钢坯下料、加热、成形、锻后冷却。锻造的工艺方法有自由锻、模锻和胎膜锻。生产时，按锻件质量的大小，生产批量的多少选择不同的锻造方法。

The forging process is generally  of the following processes，沈阳forging， namely，forging谁家好， the selection of high billets， heating， forming and cooling after forging. The forging process includes free forging， die forging and fetal membrane forging. When manufacturing， according to the size of forgings and the number of production batches， different forging methods are chosen.

通过锻造能消除金属在冶炼过程中产生的铸态疏松等缺陷，forging厂家，优化微观组织结构，forging价格，同时由于保存了完整的金属流线，锻件的机械性能一般优于同样材料的铸件。

Forging can eliminate the defects such as casting porosity and so on during the smelting process， and optimize the microstructure. At the same time， because of the intact metal flow line， the mechanical properties of the forgings are generally better than those of the same materials.

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.
