After forging, forgings tend to have residual internal stress and uneven microstructure. Annealing or normalizing is required to optimize their properties, laying a foundation for subsequent processing or application. Although both processes consist of core steps of heating, heat preservation, and cooling, their parameter controls differ significantly, and their effects on forging properties also have distinct focuses.

In forging processing, cracks and folds are core defects that affect the quality of forgings. They not only reduce the mechanical properties of products but also may lead to fracture risks in subsequent processing. Identifying the causes of these two types of defects and implementing preventive measures is crucial to ensuring forging quality.

In forging processing, post-forging deformation, surface oxidation, and internal porosity often lead to product scrapping. It is necessary to develop scientific handling strategies based on the causes of these problems, while strengthening preventive measures to reduce quality risks.

The quality of forgings directly determines the safety and stability of downstream equipment. Cracks, inclusions, and dimensional deviations are key defects that require strict control during processing, and a dual approach of "prevention + inspection" is necessary to build a solid quality defense line.

Dalian forging and casting, as the two core processes of metal forming, have essential differences in performance. Forging relies on "plastic deformation to reshape the structure" as its core, while casting relies on "liquid forming to fill the cavity". The different process paths have created significant advantages in key performance of forged parts.

Dalian forging processing uses external forces to cause plastic deformation of metal billets, reshaping the internal structure of materials and becoming the core process for improving component strength. The core logic is to break and reorganize metal grains through forging, eliminate defects such as porosity and looseness in the cast state, and achieve a significant increase in material density, laying the foundation for high-strength industrial components.
