Severstal and iPavlov agree on strategic cooperation in the development of accurate measurement systems

2021: Agreement on Strategic Cooperation in the Development of Accurate Measuring Systems

The AI company iPavlov (LLC Aipavlov, spin-off from MIPT) and the public joint-stock company Severstal entered into an agreement on "Establishing and developing partnerships between Organizations based on the integration of scientific, technical and innovative capacities of the Parties." The document was signed by Laurent Hakobyan, CEO of iPavlov, and Peter Mishnev, Director of Technical Development and Quality of Severstal Russian Steel Division. This was announced on April 22, 2021 in iPavlov.

Severstal and iPavlov agree on strategic cooperation in the development of accurate measurement systems

The agreement confirms the strategic scientific, technical and technological cooperation of Severstal iPavlov in 26 areas of digital modernization of the metallurgical industry, including:

• Video inspection system for identification and classification of defects of x/k rolled stock;
• A system of promising profilometers on new (including non-traditional) physical principles;
• Universal software interface system for monitoring systems;
• Light spot control systems (prints);
• Residual stress monitoring systems in the material;
• Automated NDT of internal stress level in metal rolling;
• Zinc coating thickness measurement system on the product (sheet, wire) in the stream);
• System of configuration of video inspection system of cold rolled metal rolling based on integrated vision system;
• System of high-precision laser scanner geometric dimensions of stationary part;
• Wire diameter laser meter system;
• High-precision laser thickness meter system, etc.

At this stage of Severstal's digital transformation, the developers iPavlov revealed the details of two pilot projects: * a video surface inspection system for recognizing and classifying defects x/c of rolled stock ,

• and the development of promising profilometers on new (including non-traditional) physical principles.

The video inspection system will feature 100% automated control of the surface quality of the strip of produced metal rolling on both sides, without omissions and blind spots at a cutting speed of up to 6 m/s and a maximum roll width of 1600 mm; and recognition, count and classification of defects according to the list of critical defects of the POD. During commissioning, the system will mainly identify the root causes of obtaining inappropriate products, as well as reduce the level of sorting.

As part of the second pilot project, profilometers will be developed on new physical principles with a line width of up to 700 mm. The development will be carried out by the NIC JSC Schwab"" at the MIPT by order of Aipavlov LLC. The main feature of the equipment should be high accuracy (absolute error in z coordinate (height) - 0.2 mm or absolute measurement error of 1 μm for the control object moving at a speed of 2 m/s), while observing the average cost of the established economic limits of the client. We are talking about technology that provides cheaper products. The search for such technology and its development under specific production conditions is the most time-consuming component of the work, explained in the iPavlov.

"The development of this direction corresponds to Severstal's digital transformation strategy. A significant improvement in the quality of our products while reducing losses and production costs is impossible without digital assistants - machine vision, artificial intelligence, complex systems. Such solutions allow improving industrial processes that require rapid analysis of a large amount of information, high accuracy and speed of measurements, flexibility and adjustment of algorithms to technological needs. The partnership agreement with iPavlov contributes to the modernization of the digital course of our company, and at the same time becomes an example of the search for scientific potential, innovative ideas and solutions in the field of AI for the implementation of tasks in Russia.
