How to identify the quality of forging

The main task of forgings quality inspection and quality analysis is to identify the quality of forgings, analyze the causes of forgings defects and preventive measures, analysis and research
It is an important way to improve and guarantee the quality of forgings to investigate the causes of defects and put forward effective prevention and improvement measures. A variety of defects form from forgings
As can be seen, the factors affecting the quality of forging are many, in addition to the quality of raw materials has an important influence, but also with the forging process and
The heat treatment process is closely related. Therefore, the analysis and research of forging quality problems, is a careful and complex work.
The general process of quality analysis of forgings is:
1. Investigate the original situation, including the investigation of raw materials and forging process. The former should understand the quality of raw materials, as well as the smelting of raw materials
Refining and processing technology. The latter should investigate whether the forging process specification is reasonable and the actual implementation of forging production.
2. Make clear the quality problem, mainly to make clear the cause, find out the defects of forging parts and the macro characteristics of defects, preliminary judgment is caused by raw materials,
Or the forging.

3. Experimental research and analysis, which is the main stage to determine the cause of the defects of forgings, that is, the defective forgings are sampled and analyzed to determine the macro and micro groups
The character of weaving; If necessary, comparative test of process parameters is also needed to study and analyze the causes of forging defects.
4. Proposed solutions, based on the clear causes of forging defects, combined with the production practice, proposed preventive measures and solutions.
The test methods of forgings quality analysis include: low-power microstructure test, metallographic microstructure test and metal deformation and flow analysis test. As mentioned earlier, lower times
The test can expose the macroscopic defects of forgings. Metallographic microstructure test is helpful to study and analyze the microstructure characteristics and formation mechanism of defects. And metal deformation flow analysis test
It is of special significance to the analysis of crack, folding, coarse-grain formation and streamline distribution. In forgings quality analysis, is often combined with the above three
To carry out. With the rapid development of modern technology, some advanced test techniques such as non-destructive testing methods, electron microscopy, etc., are also used to analyze forgings
Quality makes the quality analysis method to be accurate, fast and efficient.
