Introduction – Tuyere Refractory Monitoring System
The tuyere refractory monitoring system is a critical solution in the steel industry for ensuring safe blast furnace operations. In the BF process, coke powder is injected through tuyere pipes, generating extremely high temperatures.
Due to continuous exposure to hot coke particles, the refractory lining in the blow pipe area often experiences erosion and damage. To prevent this, industries are now adopting online thermal camera systems for continuous monitoring and early fault detection.

Understanding Tuyere and Blow Pipe Operation
In a blast furnace, tuyere pipes are responsible for injecting coke powder and air into the furnace. Just below the tuyere lies the blow pipe, which is exposed to intense heat and material flow.
Over time, hot coke deposition causes:
- Refractory erosion
- Surface weakening
- Increased thermal stress
If not monitored, this can lead to serious operational risks.
Problem – Refractory Erosion in Blow Pipe Area
The continuous flow of hot coke powder leads to gradual wear of refractory material. This erosion reduces insulation capability and increases external surface temperature.
Major risks include:
✔ Structural damage
✔ Heat leakage
✔ Safety hazards
✔ Blast furnace instability
This is why early detection is extremely important.
Solution – Tuyere Refractory Monitoring System
The tuyere refractory monitoring system uses online thermal cameras to monitor the temperature of blow pipes and tuyere zones in real time.
