Marine crankshaft forgings are the key parts in the ship power system, and their quality is of great significance to the normal operation and safety of the ship. Quality inspection technology is an important means to ensure the quality of crankshaft forgings. This paper will discuss the quality inspection technology of Marine crankshaft forgings and its application status.
Quality detection technique
Appearance inspection: The appearance inspection of crankshaft forgings by visual or low-power magnifying glass, including surface cracks, inclusions, oxide and other defects.
Size detection: Measuring tools are used to measure the dimensions of each part of the crankshaft forging, including diameter, length, thickness, etc., to ensure that the dimensional accuracy meets the design requirements.
Hardness testing: The surface hardness of crankshaft forgings is tested by a hardness meter to evaluate its wear resistance and fatigue resistance.
Ultrasonic testing: The use of ultrasonic probes for non-destructive testing of crankshaft forgings, found internal cracks, pores and other defects.
X-ray detection: Through radiographic technology to detect the crankshaft forging inside, found internal cracks, pores and other defects.
Application of automated inspection technology: With the development of science and technology, automated inspection technology has been widely used in the quality inspection of Marine crankshaft forgings. Automated detection technology can improve the efficiency and accuracy of detection and reduce the influence of human factors on detection results.
Intelligent detection technology application: Intelligent detection technology combined with computer technology and artificial intelligence technology, can be real-time monitoring and early warning of crankshaft forgings, improve product quality and production efficiency.
Application of online inspection technology: Online inspection technology can detect the crankshaft forgings in real time during the production process, find and deal with quality problems in time, and avoid quality problems after the product enters the market.
The quality inspection technology of Marine crankshaft forgings is of great significance to ensure product quality and safety. At present, the automatic, intelligent and online inspection technology has been widely used in the quality inspection of Marine crankshaft forgings, which improves the inspection efficiency and accuracy. In the future, with the continuous progress and innovation of science and technology, quality detection technology will be more intelligent, automated and efficient, providing a strong guarantee for the quality improvement and safe production of Marine crankshaft forgings.
