Russian steel maker NLMK has implemented a new digital service at NLMK Kaluga based on machine vision and artificial intelligence, which determines the type and quality of scrap delivered to the plant. The solution saves time for employees to control incoming products, increases the turnover of wagons, and improves the quality of interaction with suppliers. Industrial cameras installed at the NLMK-Kaluga pre-production site transmit the video stream to the system, which analyzes each unloaded layer of raw materials in all cars. The service can also block the unloading of items that are prohibited for unloading, for example, potentially explosive.Based on an accurate analysis of each delivery of scrap, the service generates a report for each wagon. All photos and videos linked to the wagon register are stored in the service history. Access to reports on the acceptance of raw materials with layer-by-layer photos of the unloading of railcars is available to suppliers on the NLMK Group portal.In 2022, the digital service will be replicated at NLMK Group's production site in Lipetsk, and later on at other Group facilities.
