In recent years, as the demand for steels of high added value, such as the ultralow carbon (ULC) steels, the demands on the Ruhrstahl-Heraeus-oxygen blowing (RH-OB) process, have increased. In order to meet these strong demands, the RH-OB equipment at Taranto Works has been revamped, particularly by means of the enlargement of the snorkel diameter. This has led not only to increase in the decarburisation rate due to the improvement of the metal recirculation, but also to an increase in productivity, improved process control and savings in electrical power and process gas consumption. © 2010 Maney Publishing.
