【Abstract】 A casting aluminum alloy hot cracking tendency detection system based on real-time data acquisition was developed. The system integrates temperature and tensile sensors to monitor the temperature and tensile changes of aluminum alloys during solidification in real time, plot cooling curves and shrinkage tensile curves, extract characteristic values, and calculate the hot cracking index, achieving accurate determination of the hot cracking tendency of aluminum alloys. Experiments on the hot cracking tendency of Al-Cu alloys were carried out, and the results show that the system has significant advantages in the accuracy and real-time performance of hot cracking detection. The detection results can provide data support for aluminum alloy casting structure design and casting process optimization.更多还原
