What are the common defects of chain link forging and how to avoid them?

There may be some common defects in the production process of chain link forging, including internal defects and external defects. Internal defects include cracks, inclusions, pores, etc. These defects will affect the strength and reliability of the chain link forging. External defects include oxide skin, surface cracks, size deviations, etc. These defects will affect the beauty and performance of the chain link forging.

In order to avoid these defects in chain link forging, the following measures can be taken:

Optimization of forging process: By optimizing the forging process, the production of internal defects can be reduced. For example, a reasonable choice of forging temperature and forging speed can avoid cracks and deformation of the material.

Strict control of material quality: the quality of the material has a great impact on the quality of the chain rail forging. Therefore, it is necessary to choose high-quality materials and carry out strict quality control.

Strengthen forging post-processing: forging post-processing is an important link to ensure the quality of chain rail forging. Therefore, it is necessary to strengthen post-forging processing to ensure dimensional accuracy and surface quality.

Increase the surface treatment process: The surface treatment process can reduce the occurrence of external defects. For example, the addition of equipment such as oxide cleaning machines can remove surface oxide and cracks.

Strengthen quality inspection: Quality inspection is the last line of defense to ensure the quality of chain rail forging. Therefore, it is necessary to strengthen quality testing and timely treatment and repair of unqualified products.

In short, there may be some common defects in the production process of chain link forging, but as long as the corresponding measures are taken, these defects can be avoided. In the production process, it is necessary to strengthen quality control and management to ensure that each link meets the requirements, so as to improve the quality and performance of the chain rail forging.
