Principle:
A stroboscope is a device used to make a cyclically moving object appear to be stationary or slow- moving. It works on the principle that a lamp emits brief and rapid flashes of light, when the frequency of the flashes matches the frequency at which the object is moving, the object appears to be moving slow or stationary. For this same reason, Stroboscope can be used in various industries for various quality control and inspection operations.
Applications in Steel Industry:
In steel industry, rolling mills that make hot-rolled and cold rolled sheets, coils etc. face defects like scratches, dents etc. during the production process. These sheets are made at a very high speed of minimum 200m/min. So, there is no possibility of these defects getting identified during the production stage.
Sugawara’s LS-500 Fixed Stroboscope is the most suitable device to detect these defects easily during the production process. It works on the principle that a lamp emits brief and rapid flashes of light, when the frequency of the flashes matches the line speed, the sheet/coil appears to be moving slow or stationary and the defects like dents, scratches can be easily identified.
LS-500 has a maximum flash frequency of 60,000 FPM. The frequency and the duration of the flashes can be easily synchronized with the line speed with the help of the CB-LS Controller. LS-500 uses ultra-bright LEDs for uniform illumination of a range of 80 x 40 cm brightly from a distance of 1m and this area can be easily extended by combining multiple units (upto 12) of LS-500 to match the width of your production line. Since LS-500 uses LEDs, it also has lower energy consumption and running
costs because there is no need for lamp replacement.
In Conclusion, Stroboscope provides greater efficiency in the steel plants. By using this stroboscope, steel coil mills can improve the consistency of coil quality, eliminate downtime and maintenance, reduce energy costs, and improve safety.
