In hot forging forging production, quality control and inspection is the key link to ensure product quality and performance. Through effective quality control and testing, defects can be reduced, product pass rate can be improved, so as to meet customer needs and enhance the competitiveness of enterprises. This paper will discuss the quality control and inspection methods and importance in the production of hot forging parts.
Quality control of hot forging production
Raw material control: The quality of hot forging first depends on the quality of raw materials. Qualified suppliers should be selected, and the chemical composition, physical properties and other indicators of raw materials should be strictly inspected to ensure that they meet the production requirements.
Process parameter control: hot forging process parameters such as temperature, pressure, time, etc., have an important impact on forging quality. A perfect process parameter control system should be established to ensure that the parameters of each process step are within the appropriate range to reduce defects and variability.
Operating specification control: The skills and operating specifications of the operator also have a certain impact on the quality of hot forging forging. Detailed operating procedures should be developed, training and guidance provided to ensure that operators are skilled and comply with the code.
Detection of hot forging parts
Non-destructive testing: Non-destructive testing refers to the testing carried out without damaging the integrity of the forging. Common non-destructive inspection methods include visual inspection, dimensional measurement, X-ray inspection, ultrasonic inspection and so on. These methods can effectively detect surface defects, internal cracks and dimensional accuracy of forgings.
Destructive testing: Destructive testing is a testing method that destroys a sample to observe its internal structure and properties. Commonly used destructive tests include tensile test, impact test, hardness test and so on. These tests can provide important indicators such as mechanical properties and material organization of forgings to determine whether they meet the design requirements.
Quality control and inspection is a continuous optimization process. The enterprise shall establish a quality management system and formulate a quality improvement plan. Through data analysis, problem location, cause analysis and other methods, constantly improve the hot forging process and detection means, improve the stability and controllability of the production process, reduce the defect rate and scrap rate.
At the same time, strengthen the communication and cooperation with suppliers and customers, timely understand the market demand and feedback, further improve the quality control and testing system, and improve customer satisfaction.
Quality control and inspection in the process of hot forging forging is the key link to ensure product quality and performance. Through raw material control, process parameter control, operation specification control and other means, combined with non-destructive testing and destructive testing methods, the quality level of hot forging can be effectively improved. Continuous optimization of quality control and inspection systems will help enterprises reduce production costs, improve market competitiveness, and provide customers with better products and services.
