Continuous casting machines in steel production rely on precise control systems to manage the flow and solidification of molten metal. This transducer type is installed within the secondary cooling zone, where it monitors the temperature distribution across the slab surface, enabling real-time adjustments to coolant flow rates. By providing accurate feedback to the control system, it ensures uniform cooling and minimizes defects such as surface cracks or internal voids. The device is embedded in the cooling water circuit, interfacing with programmable logic controllers to maintain optimal thermal profiles. Its integration into the automation loop enhances process stability, reducing rework and improving yield. In secondary steelmaking plants, this component plays a critical role in maintaining the integrity of cast products. Its placement within the cooling infrastructure allows for continuous monitoring without disrupting the casting cycle, supporting high-throughput operations in modern steel mills.
