Steelmaking - Oxygen steelmaking

Oral

The RecoDust process is an innovative pyrometallurgical technique designed for the efficient separation of iron and zinc from steel mill dust, a byproduct of steel production. This process addresses the growing demand for sustainable resource recovery in the metallurgical industry, offering an environmentally friendly and economically viable solution for the recycling of valuable metals....

325. Online Temperature and Deformation Measurement for Vessel Shell of Oxygen Steelmaking Converters

Piotr Szamburzki (Danieli Corus)

09/10/2025, 10:40

Steelmaking - Oxygen steelmaking

Oral

Information regarding temperature and deformation of the converter shell, particularly the barrel section and top cone, help predict remaining lifetime of top cone, detect damages in refractory, etc. Since the trunnion ring obscures much of the view on the converter, thermal cameras do not provide this information. Hence, sensors have to be arranged directly on the vessel shell. Unfortunately,...

245. Problem solving with modeling support: evaluation with a numerical fluid dynamic model of the different configurations of the slag-cutting deflector for oxygen jet lance tips in the BOF

Mr Alessandro Dell'Uomo

Steelmaking - Oxygen steelmaking

Oral

In the primary steel production, hot metal produced in the blast furnace (BF) is fed via a ladle to the Basic Oxygen Furnace (BOF), where it is converted to liquid steel. During the metallurgical operations, slag can form and solidify on the refractory walls during tapping. These oxide deposits must be periodically removed, to ensure the regularity of BOF operations over time.
