Application of In-Furnace Laser Detectors for Billet Positioning in Reheating Furnaces
Eu. Product Overview
The In-Furnace Laser Detector (Link) is a high-power laser detector designed for harsh industrial environments in metallurgy. Equipped with an infrared semiconductor laser emitter, it delivers exceptional penetration and ultra-long working distances, ensuring stable performance in extreme conditions (high temperatures, humidity, mist, dust, etc.).
II. Working Principle
The detector operates on the principles of laser linear propagation and reflection:
Laser Emission: The infrared laser beam is emitted toward the furnace interior.
Reflection: The beam reflects off the billet surface.
Signal Reception: The reflected signal is captured by the receiver and converted into an electrical signal.
Position Calculation: Billet position and distance are determined using signal intensity and time delay analysis.
III. Application Scenarios
In reheating furnaces, the detector is primarily used for:
Billet Position Monitoring:
Tracks real-time billet positions to ensure proper alignment during heating, improving thermal uniformity and efficiency.
Automated Control Integration:
Interfaces with furnace automation systems to enable auto-positioning and tracking. Adjusts heating parameters or triggers control actions based on billet movement.
Safety Protection:
Monitors billet trajectories and positions to detect anomalies, triggering alarms or emergency shutdowns to safeguard personnel and equipment.
IV. Key Advantages
The detector excels in billet positioning applications due to:
High Precision & Stability:
Advanced laser technology and signal-processing algorithms ensure submillimeter accuracy.
Strong Penetration Capability:
Infrared laser emitter penetrates high-temperature zones and dense particulate environments.
Ultra-Long Working Distance:
Supports billet positioning in large-scale furnaces (up to 100+ meters).
Ease of Integration & Maintenance:
Standardized interfaces (e.g., Modbus, Ethernet/IP) simplify integration with control systems. Low-maintenance design reduces operational costs.
V. Conclusion
The In-Furnace Laser Detector enhances reheating furnace operations through precision positioning, rugged reliability, and automation compatibility. By optimizing heating efficiency, safety, and maintenance workflows, it drives sustainable advancements in metallurgical production.
