9th International Conference on Modeling and Simulation of Metallurgical Processes in Steelmaking - STEELSIM2021

In additive manufacturing of metals, high quality powder with uniform size distribution and spherical, satellite-free particles of defined size is required. SMS group has built-up a metal powder production plant which operates using the close-coupled atomization principle. For reliable plant operation, it is important to understand the atomization mechanisms, i.e. the effect of plant...

Increasing interest in the direct reduction of Iron has revived investigations on the kinetics of gaseous reduction of iron oxides. Despite extensive investigations on the reduction of iron oxides with pure hydrogen or with syngas, the development of a generic reduction mechanism of iron oxides is still lacking. The conventional shrinking core model hardly distinguish between transport...

The current work and paper bases on a new iron production route which uses iron ore fines direct reduction. This technology was invented by ENRAG and PRIMETALS and is in ongoing development by Primetals Technology. It is called HYFOR. This new direct reduction technology uses iron ore fines instead of pellets and is therefore more energy efficient and uses cheaper ore material compared to...

Iron and steel production is an energy-intensive process, often associated with high greenhouse gas (GHG) emissions. There is a drive to reduce GHG emissions in energy-intensive industries. However, the existing technologies used for reducing CO2 emission have reached a plateau. The emergence of novel technologies such as carbon capture, utilisation and storage systems are proposed as a new...

The H2020 project POLYNSPIRE was launched to improve energy and resource efficiency of post-consumer and post-industrial plastic recycling processes, targeting 100% waste streams. Pillars to reach this ambitious goal are: (1) Chemical recycling to recover plastic monomers and valuable fillers, (2) Advanced additivation to enhance recycled plastics quality, (3) Valorization of plastic waste as...
