LANIT Group’s Datana has developed a set of digital solutions to improve the quality of the products of the oxygen-converter shop of Russian steel maker MMK. A hardware and software system was installed on the ladle furnace to control the metal blowing with argon. An important advantage of the work performed is the equipping of steel-making units with additional equipment, means of monitoring the production process, which allows the company's specialists to continue to use the tools to optimize the technological operations used.The complex consists of a robotic arm designed by Datana engineers, a camera in a protective casing for collecting streaming video data at high temperatures, as well as an ensemble of mathematical models based on neural networks. In real time, the complex performs video recording and analysis, evaluates and issues recommendations for the steelmaker. Thanks to the work of the hardware and software complex, it is easier to observe the production process, which has a positive effect on the quality of products.A system for optimizing the decarburization process was installed on the steel vacuuming unit. A physicochemical model was developed, reinforced with ML-models. The system recommends optimal modes and predicts the time to reach the target carbon in the melt, which reduces the evacuation time.A slag detection system is installed on two continuous casting machines. To solve this problem, a vibrodiagnostic method of data collection was used and an ML-model was developed, which allows detecting slag in the metal flow during steel casting and recommending the optimal time for stopping the operation. The system allows to reduce the amount of slag entering the tundish, increasing the quality of continuously cast slabs. The tests of these solutions were carried out on the out-of-furnace treatment and continuous casting units and confirmed the effectiveness of the developments.LANIT, Laboratory of New Information Technologies, is a leading multidisciplinary group of IT companies in Russia and CIS. LANIT is a private company, established in 1989. LANIT supplies a complete set of modern information technology services including development, installation, implementation of hardware and software complexes in addition to personnel training.
