Testing of Rolling Mill Rolls

- Eddy current dual frequency
- Ultrasonic and surface waves

AS US ZENI


The reference in rolling mill roll eddy current testing, dual frequency. Ultrasonic and surface waves.

AS-US-ZENI V2, assembles the last ACTA technologies to test your roll table.
New dual frequency technology used to test simultaneously with high and low frequencies surface and internal cracks.
Complementarities of methods, eddy current dual frequency, ultrasonic and surface waves to detect all defects on and inside the roll.
