Slab detection: on the transfer table
Smart Radar Sensor for width measurement Hot Rolling Mills
Challenges
- High ambient environment: photocell is sandwiched between charged slab front and back side.
- Water cooling is not effective as thin capillary cooling tubes are used, which just cools the electronicspartially.
- Contamination in water cooling line can block the circulation of the water in sensor.
- Cooling circulation is only on the side surface, which is not an effective method.
Burnt electronics:
Choked circulation as the water is not clean
Customer Benefit
The high accuracy distance sensor with radar system-
- Contactless, inline measurement of slabs, strips, and plates (up to 1600 °C).
- Accuracy up to ±300 µm even in harsh environments
- Independent of alloy or metal type.
- Eliminates radiation hazards and reduces cost.
- Improved safety level as plant operators were not required to go in the high temperature zone to verify the water-cooling functionality.
- No housing and water cooling required.
- Better handling of the operational process.
- Zero process interruptions.
