Brief Introduction:
The blast furnace infrared temperature monitoring system is a specialized imaging equipment designed for high-temperature environments using compressed air cooling. The probe features double-layer stainless steel with interlayer ventilation for direct cooling. Compressed air in the inner layer forces cooling for the infrared thermal camera and lens while forming a wind curtain at the front pinhole to suppress flames and dust. This effectively reduces heat radiation from the high-temperature furnace.
This equipment extends the infrared thermal camera lens through the furnace wall, allowing direct observation of material melting, workpiece operation, and flame shapes. It is widely applied in metallurgy, electric power, building materials, chemical, and glass industries for heating furnaces, steam boilers, and sintering furnaces to ensure production safety and automate process debugging.
