NORDISCAN-BB / EMATEST-BB
NORDISCAN-BB is a family of systems intended for a reliable automatic ultrasonic examination of bars, billets and rails. The test can be performed on-line or off-line.
NORDISCAN-BB can solve the following industrial tasks:
- Detection of surface and sub-surface defects.
The reference depth of cracks to be detected starts from 0,2 mm;
- Detection of inner defects, like shrink holes, insulation, blowholes, inclusions, etc.
Reference size of reflectors starts from 0.8 mm for aluminium bars/billets
and 1.2 mm for steel bars/billets.
Depending on the Testing requirements, NORDISCAN-BB can be equipped with different types of multichannel ultrasonic probes:
- Non-contact array probes, based on the EMAT;
- UT phase array probes;
- UT probes with the array of piezo-crystals.
Depending on the organization of the transport line at the Customer site, NORDISCAN-BB can have at least two different configurations:
- Pass-through configuration, when the bars are transported
by the regular roller conveyor through the test station;
- Portal-based configuration: a bar is put into rotation;
the Test Unit performs its scanning moving along the rotating bar.
