Advantages achieved in production
Initial experience in operation show lived up to expectations. Production processes are now running considerably more stably. The standard functions of the level-2-solution from Primetals Technologies together with the coupling to level 1 and to level 3 (production planning system) and the laboratory now allow a great deal more valuable and relevant data to be saved, and more reports to be generated. This improves the overview for the plant operator and offers a broader basis for analyses to improve the process.
Real-time calculations by dynamic process models
The heart of level 2 process automation is the dynamic process model, which allows both advance calculation and online simulation of the process. Calculating the melts in advance enables errors to be avoided, because the input materials are prepared in good time. The dynamic process model is based on dozens of metallurgical equations, which use a cyclic online calculation to calculate the chemical reaction in the AOD converter both currently in real time and at a point in the future. The precise, real-time calculation of the development the temperature and carbon during production improves both process accuracy and the quality of the stainless steel produced.
Valuable know-how successfully digitalized
One of the important advantages of the modernization of the level 2 process automation of the AOD converter is that all significant process data is collected by the digital twin from Primetals Technologies, which creates a valuable knowledge database for use in future optimizations and new developments. This digitalizes the know-how of many experts at Jindal Stainless Ltd., and this digitalized knowledge is now equally available to all levels, thus making a major contribution toward maintaining the stainless steel produced by Jindal Stainless Ltd. at a consistently high quality.
