MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202637123565 A) filed by Sms Group Gmbh on October 15, 2026, for Method For Optimizing A Pig Iron Desulfurization Process.
Inventors include Schmidt, Thomas; Kubbe, Andreas; and Bruns, Michael.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The invention relates to a method for optimizing a pig iron desulfurization process (1), wherein the pig iron desulfurization process (1) is carried out by dispensing one or more desulfurization agents (2, 3, 4) into a pig iron ladle (5) or a torpedo car, wherein a plurality of treatment patterns are available which differ with respect to the type of desulfurization agents (2, 3, 4) dispensed. The optimization is based on creating a separate model (8) for each of the plurality of treatment patterns in order to optimize the added amounts of the desulfurization agents (2, 3, 4) for the associated treatment pattern, and training (9) the created separate models (8) for each of the plurality of treatment patterns after a predefined number of performed pig iron desulfurization processes (1) with the corresponding treatment pattern. Future pig iron desulfurization processes (1) are optimized on the basis of the predictions of the separate models (8), wherein the optimization determines a treatment pattern and the added amounts of the desulfurization agents (2, 3, 4) for the treatment pattern by means of a comparison of the predictions of the separate models (8). The invention also relates to a system and a computer program which are designed to carry out the method according to the invention.
