Split-Type Load Cell for Smelting Furnace Structures
A smelting plant wanted to improve the safety and reliability of its furnace support
structures. After years of continuous operation, the plant faced increasing concerns about structural overload risks that were difficult to detect using traditional inspection methods.
To address this, the plant introduced a real‑time load monitoring and overload prevention system. This system utilized a customized version of ANYLOAD’s 363HS to enable digital monitoring of critical production equipment in a high-temperature environment without disrupting ongoing operations.
도전 과제
- Non-Modifiable Load-Bearing Structures: It was strictly prohibited to dismantle, cut, reweld, or perform any work that would alter the original mechanical integrity of the furnace support structures.
- Incompatibility of Conventional Sensors: Traditional ring-type load cells typically require the load-bearing element to pass through the sensor body. Installing such sensors would require removing/lifting the furnace support structures, which was strictly prohibited.
- Extreme Heat Constraints: The installation area is exposed to intense radiant heat from the smelting process. This application requires load cells designed for reliable performance in high-temperature environments.
솔루션
- Clamp-On Design: The load cell design consisted of two semi-circular halves that clamped directly around the existing support column. This approach eliminated the need for through-hole installation or disassembly of the load-bearing structures.
- High-Strength Bolted Fastening: Bolted connections securely lock the two halves of the load cell onto the column. On-site installation does not require any changes to the furnace support structures.
- Heat-Resistant Design: The load cell’s materials and sealing processes were specifically designed for smelting environments. This ensures high signal stability under high heat radiation (up to 150 °C), with the possibility to configure additional thermal protective layers as needed.
결론
ANYLOAD’s custom split-type load cell enabled real-time structural monitoring without modifying or dismantling existing furnace support structures. Continuous load measurement with overload early-warning capability further enhanced operational safety. This allowed a more proactive approach to risk management and improved the long-term structural reliability of the smelting furnaces.
