Infrared imaging technology using non-contact testing methods is an emerging technology in the field of equipment diagnosis, which generates temperature field images based on the invisible thermal radiation emitted by the measured target. As an important non-destructive testing method, infrared thermal imaging technology has the advantages of being intuitive, fast, comprehensive, highly accurate, easy to use, and capable of remote detection. It can directly determine the temperature distribution of various parts of thermal equipment according to application requirements, and indirectly infer the real-time status of its lining. Our company has successfully applied this advanced technology to the condition detection of blast furnaces, hot blast stoves, and hot air pipelines.

Diagnose the status of the hot blast stove through thermal testing and technical means such as infrared thermography, and quickly achieve the "hot blast stove working state"; Lesions "; diagnosis. Resolve the issues of air supply capacity and safety production in the middle and later stages of the hot blast stove.

The online maintenance technology for hot blast stoves has the characteristics of non-stop operation and not affecting normal production scheduling. It achieves rapid repair of hot blast stoves in production status, reducing the temperature of the repaired hot blast stove shell to a normal level of around 120 ℃ and extending the service life of the hot blast stove.
