Problems solved by technology
[0004] During the solidification process, the entire melt is gradually cooled from the highest temperature to the lowest temperature. At the same time, the volume fraction of the solid phase is continuously increasing, and the sound field distribution in the system is also changing dynamically. Therefore, it is necessary to monitor the sound field during the solidification process in real time. Detection requires not only a sound field detection system that can be applied in a high temperature environment, but also a sound field detection system that can work stably and reliably. System and method for sound field detection

Description
technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a sound field detection method in a high-temperature solid-liquid two-phase environment with temperature protection. Background technique [0002] Vibration solidification is to apply vibration to the molten metal in the solidification process, so that the crystal structure of the casting is refined due to the vibration, the residual stress of the casting is reduced and homogenized, and the mechanical properties are improved; the application of vibration in the field of metal solidification has aroused widespread interest. Pay attention to. Sokolov was the first to use a high-frequency device in 1935 to apply vibrations to the solidification process of pure metals. During the same period, Loomis et al. studied the law of applying ultrasonic vibration during the solidification process of metals and organic matter, and Eskin et al. explored the law of metal solidif...
