1. Real-time Monitoring at All Time
The system is using an infrared thermal imager, which can capture image at all time, this will provide video support when Blast Furnace is off-line for maintenance.

2. Deposit Dust Free Design
The system is using our company’s unique design. The protector has pre-set air guide groove,which offer the cooling air clean the lens while it blow through the whole protector.

3. Sharp Lens and High Resolution Camera
The system combines a 640×480 high-resolution needle-hole camera and a special coated heat resistance lens to ensure the sharpness of image.

4. Intelligence Software
The intelligent software measures the temperature of the burden surface by process the data feedback from the camera, and generates a temperature profile. The software also can generate a 3D model of the burden surface. All data will be save to system automatically.

5. Advanced Protection
The system is adopted with automatic enter and withdraw system, when the supply of cooling medium is irregular, or the temperature inside the protector is higher than preset value, the system will automatically withdraw. This also makes on-line maintenance available. The system is using pneumatic cooling only.

6. Safety
The system applies a unique gate valve and ball valve. When the protector withdraws the gate valve and ball valve automatically close, to prevent the spill of coal gas. There is a check-valve structure, when the coal gas supply broken or sudden pressure drop. The structure can prevent the spilling of coal gas.
