Non-Destructive Testing of Slabs

ULTRASLAB

ULTRASLAB is equipment for automated non-destructive testing of continuously cast billets (slabs) in the cold and hot state, at temperatures of up to 1000 °C.

EQUIPMENT FEATURES

Ultrasonic testing with electromagnetic acoustic transducers (EMAT);
automatic detection of surface defects on both sides of the continuously cast billet (slab);
automatic detection of internal defects in the continuously cast billet (slab);
automatic detection of cracks in the slab edge zone;
additional scanning of the slab surface with high-temperature laser triangulation 2D scanners.

MAIN EQUIPMENT SPECIFICATIONS

Slab width	up to 2400 mm
Slab thickness	up to 320 mm
Slab temperature	up to 1000 °C
Types of typical defects to be detected	Internal slab defects (laminations, non-metallic inclusions, structural porosity) Surface and subsurface defects (longitudinal and transverse orientation, spider cracks, edge cracks, gas blowholes)

MEASURING MODULE DESIGN

Similar to the ULTRAPLATE measuring module: in-line or off-line (separate area) configuration.

Additionally equipped with a system for continuous laser scanning of the entire slab surface with 2D scanners to detect local slab surface anomalies.

Laser 3D scanning of the slab surface for local surface anomalies (defects).

EQUIPMENT LOCATION

Two installation options are possible:

In a separate non-destructive testing area (for example, in the slab yard);
In-line after the continuous casting machine (CCM), immediately after the strand is cut into slabs, at slab temperatures of up to 1000 °C.
