Ultrasonic Distance Sensor Solution for Detecting Semi-Finished Products in Hot Rolling Steel Production Lines
Ultrasonic Distance Sensor Application Background
In the hot rolling process of steel production, the automated handling of cooled semi-finished products (such as steel ingots and plates) under harsh conditions—high temperatures, heavy dust, and strong vibrations—is critical to ensuring continuous production and equipment safety. Traditional contact-based detection methods are prone to failure due to issues such as heat damage, mechanical wear, and environmental contamination. Optical sensors, on the other hand, are often affected by factors like oxide layers, surface reflections, and color variations on metal materials, leading to false or missed detections.
By contrast, ultrasonic distance sensors offer non-contact measurement, strong resistance to environmental interference, and are unaffected by the target’s surface color, material, or gloss. These features enable them to deliver stable and accurate material positioning and distance detection on hot rolling lines, making them an ideal sensing solution for this application.
Core Application Scenarios of Ultrasonic Distance Sensors in The Steel and Metal Industry
Real-time monitoring of the precise position of steel ingots or metal plates on the conveyor belt to prevent material accumulation or gaps.
Detecting material presence during robotic arm picking and roller conveyor transfer processes to avoid equipment idling.
Using multi-sensor collaborative measurement to indirectly assess the uniformity of cold-rolled plate thickness.
