SUMMARY:First slab surface inspection system at continuous caster Bruckhausen thyssenkrupp Steel Europe
DESCRIPTION:The Continuous Casting Machine (CCM) Bruckhausen is part of an integrated steel plant of thyssenkrupp Steel Europe in Duisburg. The main customers are the market leaders in the packaging, automotive and electrical industries, who set high standards regarding the surface quality of their products.
Due to the closeness of CCM and hot-rolling mill in Bruckhausen, the transition time of the slabs from CCM to the hot-rolling mill is quite short. This shortness has two main advantages. Firstly, it allows to save energy which is needed for reheating of slabs. Secondly, slabs with short transition time have fewer micro cracks on the slab surface. The short transition time, however, brings a big challenge for the production process, since it limits the time available for the quality control of the slab surface and exclusion, if defects are detected. 
The most frequent defects on slabs are longitudinal and transversal flame-cutting burrs/beads and different types of cracks. In the past, the slab surface was controlled by means of thermal camera to detect those surface defects. This technique has reached its limits regarding the present challenges for the quality of the slab surface. To fulfill continuously increasing customers surface quality requirements, in March 2022 we implemented the first slab surface inspection system of thyssenkrupp Steel. It is a 3D Surface Inspection System (SIS) supplied by IMS Messsysteme. Within six months after the installation of the 3D SIS the internal quality costs as well as quality KPIs of our customers had been improved. After giving a brief introduction in the principals of 3D SIS technique we will present the main advantages of the 3D SIS in comparison to a basic thermal camera detection system, the recent impacts on quality results and next planned development steps.
