Optical LED, laser and microwave type hot metal detectors are used to detect the presence of rod, billet, bar, slab or plate in a rolling mill, continuous casting or other mill process lines. Radiated infrared from hot material passing within the operating range of the device will trigger an output function to initiate a process command.
These devices can reduce the risks of process line failures, scrap and rework by enabling the user to accurately detect product from start to finish.
Some of the applications for these Hot Metal Detectors include;
- Billet and slab continuous casting
- Entry/ Exit to the reheat furnace
- Hot strip mills
- Pipe mills
