SLAB MASTER

Detects defects on the hot slab, that would be invisible to contrast-based 2D inspection technology.

Combined 2D/3D inspection and measurement of hot and cold slabs

Modular sensor concept (scalable and precalibrated)

Multi-step classification for higher classification rates

Top and bottom side inspection

Improved process control with the earliest possible inspection positions of flat steel

Outstanding defect detection on the slab

The slab is highly structured and has a temperature of around 1,000°C. Nevertheless, the SLAB MASTER can detect defects that would be invisible to contrast-based 2D inspection technology.

Based on laser triangulation, the 3D inspection system detects and classifies all relevant defects, such as cracks or inclusions. It also measures their depth on the top, bottom and sides of the slab. Automatic surface inspection begins from the first production step, ensuring that only flawless material is transferred to downstream processes.

The ISRA InstantClassifierTM includes over 80% of all typical defect classes with its standard installation.

In addition to identifying surface defects, the inspection system calculates the size (volume and weight) of the slab.

A SLAB MASTER system typically has a payback period of just a few weeks.
