Abstract:
Proper management of industrial waste is a growing concern due to its environmental impacts and the need to promote sustainable practices in the industry. During the steel production process, several types of slag are generated: BOF/EAF, blast furnace slag and ladle and tundish slag. Steel slag is characterized by high temperature, large quantity, complex compositions, variable fluidity and unstable performance, among other characteristics. Due to the various variables, the treatment, processing, and applicability of slag represent a major challenge in the world, and an important issue that requires urgent solutions for the steel industry to fit into the context of the circular economy and sustainable development. In this context, the BSSF (Baosteel Slag Short Flow) process appears as a promising alternative for the processing of primary refining slag and greater added value in its application. In view of the numerous advantages of the byproduct generated by this process compared to the traditional method used by the steel industry, the search for continuous improvement of procedures to optimize the generation of the byproduct is mandatory. This work aims to discuss the BSSF process and the recent improvements in the ArcelorMittal Pecém process in order to increase the efficiency in the granulation rate.
