CIVS graduate student John Rosser and Post Doc Researcher Orlando Ugarte represented Purdue Northwest at the AIST Scrap Supplements and Alternative Ironmaking Conference. John and Orlando presented their research and conducted Q&A sessions after their presentations.

John’s presentation “Development of a Material Flow Model for Pellet Feed Systems” highlights an advanced CFD platform used to model the dynamics of pellets in a real DRI hopper, and what conditions may lead to clogging of the system. Orlando’s presentation “CFD Modeling of Melting of HBI/DRI in an AC Electric Arc Furnace” addressed the conditions that makes the melting of HBI/scrap more efficient in Electric Arc Furnaces.

The AIST Scrap Supplements and Alternative Ironmaking was held from March 6th through March 8th at the Wyndham Lake Buena Vista Disney Springs Resort Area in Orlando, FL. Attendees included steel industry managers, CEO’s of alternative ironmaking startups, other researchers, and various other company representatives.

This is the ninth in a series of symposia covering scrap substitutes and alternative ironmaking, which originated with a highly successful meeting in Myrtle Beach, S.C., USA, in 1993. This meeting was initiated by the Advanced Technology Committee, which belonged to the Process Technology Division of the Iron & Steel Society (an AIST predecessor). This symposium, which is international in scope and participation, is associated with a high level of activity in research, process and project development, plant construction, and start-up of direct reduction and alternative ironmaking processes. This symposium focuses on the following areas: successful projects/processes, the challenges of struggling processes, and those still under development including new approaches, and use of products.
