Primetals Technologies pioneers AI-driven computer vision to detect strip cross cracks, reducing downtime and equipment damage at thyssenkrupp Hohenlimburg's hot-strip mill in Germany.


Primetals Technologies introduces an innovative digital assistant at thyssenkrupp Hohenlimburg’s hot-strip mill, leveraging computer vision and artificial intelligence. This breakthrough AI-based solution aims to swiftly identify strip cross cracks, optimizing mill operations by mitigating downtime and minimizing equipment damage.

The implementation of this digital assistant marks a significant milestone for Primetals Technologies, representing the industry's first-ever computer-vision-based system tailored explicitly for detecting strip cross cracks.

The primary advantage for thyssenkrupp lies in the reduction of operational downtime and minimization of wear on the mill's rolls. The early detection of cross cracks on slabs prevents the propagation of these defects throughout the rolling process, averting potential damage to the finishing mill's equipment.

The digital assistant, stationed at the roughing mill's exit side, receives a live video stream from a camera. Utilizing a machine learning model powered by AI, the assistant scrutinizes the stream for any indications of cracks. Upon detection, it promptly alerts operators, enabling preventive action to forestall equipment damage. Additionally, this information feeds into the customer's intelligent business automation system for further analysis.

This cutting-edge system at thyssenkrupp Hohenlimburg will continuously evolve and refine its capabilities through self-learning mechanisms, ensuring adaptability to detect various crack types.

Located in Hagen, Westphalia, thyssenkrupp Hohenlimburg employs approximately 900 individuals and specializes in producing steel strips for various industries, particularly automotive supply. Primetals Technologies and thyssenkrupp maintain a robust partnership, evident in ongoing projects like fine-tuning process parameters using AI algorithms and the recent modernization of the plant’s hot-strip mill drive system.


Primetals Technologies’ groundbreaking AI-driven vision system heralds a new era in steel production, enhancing operational efficiency, and safeguarding equipment integrity at thyssenkrupp Hohenlimburg. This strategic alliance and innovative technology represent a paradigm shift towards smarter, more resilient steel manufacturing processes.
