How to check whether the lining of the segondè-tanperati gwo founo dife muffle is damaged?

To check whether the lining of the high-temperature muffle furnace is damaged, gravity wave detection is generally used, that is, the gravitational fluctuation signal is highly sensitive to structural defects, and the high-temperature muffle furnace lining is inspected. When the gravity wave propagates in the lining When encountering cracks, holes, cracks and other interface discontinuities, reflection, refraction, scattering and mode conversion will occur, and they are highly sensitive to defects. Based on this sensitivity of gravity waves, the signals when gravity waves are transmitted in the furnace lining are collected. By processing the collected signals such as spectrum analysis and wavelet transformation, parameters such as the propagation speed of gravity waves in the furnace lining can be further obtained. Identifying the defects of the furnace lining provides more information, so that you can determine whether there are cracks or voids in the high temperature muffle furnace lining.
