High-temperature Electric Furnace Lining Hidden Danger Investigation

Time:2025-06-16 10:56:33 Source:Shanghai Guanding Industrial Equipment Co., Ltd Views:27

In the high-temperature battlefield of industrial manufacturing, high-temperature electric furnaces continuously release intense heat, while the furnace lining, as a key internal structure, silently withstands the test of extreme temperatures. The furnace lining made of refractory ceramic materials is not only a fireproof wall isolating high temperatures from other precision components of the electric furnace but also an important guarantee for maintaining stable heat inside the furnace. Its stable performance ensures that the electric furnace can effectively utilize heat during long-term high-temperature operations, safeguarding production efficiency.

 

However, under long-term complex working conditions such as high temperature and chemical erosion, the furnace lining will inevitably suffer wear and tear. Once the furnace lining is damaged, high temperatures will erode other components of the electric furnace unimpeded, leading to frequent equipment failures, forced production interruptions, and even potential safety accidents. Therefore, timely and accurate inspection of the furnace lining status is a necessary means to ensure the safe and stable operation of high-temperature electric furnaces.

 

Among many detection technologies, the stress fluctuation signal-based detection method stands out. This technology originates from the physical characteristics of stress wave propagation in media - stress waves propagate stably in uniform media, but when encountering defects such as cracks and voids inside the furnace lining, the discontinuity of the medium on the propagation path breaks this stability. Stress waves undergo reflection, refraction, scattering, and mode conversion at the defect interface, causing distortion of the originally regular stress wave signals.

 

Professional detection equipment can capture these subtle signal changes and convert stress wave signals into intuitive images or data reports through complex algorithm analysis. Based on this, operation and maintenance personnel can accurately locate the damage position of the furnace lining and judge the severity of the defects. This detection method does not require disassembling the equipment or causing secondary damage to the furnace lining, enabling comprehensive "health diagnosis" of the furnace lining without interfering with normal production.

 

For industrial production enterprises, mastering scientific furnace lining detection technology is the key to achieving efficient equipment operation and maintenance. Guanding Industrial Equipment, with its deep accumulation in the field of industrial equipment, continues to (research) cutting-edge detection technologies, providing enterprises with professional high-temperature electric furnace lining detection and maintenance solutions to help enterprises build a solid equipment safety defense line and improve production efficiency.
