Surface defects arising during continuous casting are often perpetuated through the complete process chain for the production of the strip and heavy plate. Non-stop surface inspection from continuous casting to finished coil or heavy plate is therefore critical for the quality of the final product.

We are capable of offering both 3D systems for high-resolution capture of topographical data for slab inspection as well as 2D systems for hot and cold rolling applications.

Benefits of 3D Systems:

  • It detects surface defects and enables direct optimization of the continuous casting process.
  • Combined with 2D systems for the inspection of the hot and cold strips, it is possible to track surface defects along the complete process chain.
  • By linking the surface data with other measured data, for example, geometry or material data, it is also possible to identify and eliminate sources of error whose causes lie further to the front of the process – an important step in the quality management from continuous casting to finished coil or heavy plate products.


The 3D Systems detects and classifies surface defects such as cracks, inclusion or impressions. Apart from the extent of the surface defects, it also determines their depth.

The system works in real time and delivers the information on the slab surface immediately. Countermeasures can be taken directly during production, thereby enabling ongoing optimization of the continuous caster.

The results of the surface inspection can be used, for example, to optimize plant parameters or the adding of casting powder.

The subsequent process steps also benefit: since the severity and position of the surface defects are known, the surface inspection system minimizes the work for grinding and scarfing.

If the surface data are linked to the geometry values of the slabs, the continuous caster delivers perfectly documented products. For instance, the slabs do not need to be weighed and the risk of mix-ups is minimized.

– In order to manufacture the top quality products, all defects should be carefully examined and effectively be removed accordingly. To do so, we are able to help you provide the most appropriate customer-based solutions. Contact Us and we would be glad to be your trustable partner in this procedure.
