Metallurgy — Steelmaking & Casting Technology Committee Activities

The MSCTC had a virtual meeting 4 May 2020.
MSCTC chair Pallava Kaushik kicked off the committee’s virtual meeting by presenting the winners of the 2020 Kent D. Peaslee Award. The award plaque will be given during AISTech 2020.
The following committee officers were elected for the 2020–2021 term:

  • Chair: Bryan Webler, Carnegie Mellon University.

CATC Highlights:
The CATC reviewed its AISTech technical session development. At the time of the meeting, a total of 72 papers had been submitted for the committee. This is more papers than can fit into the five sessions at 
AISTech, so the committee discussed possible joint sessions. A small group of committee members will follow up on the session development. Seven members volunteered to be session chairs in addition to the Digital Transformation Core Team members. 
The Digital Transformation Forum for the Steel Industry will be held 16–18 March 2020 at the Omni William Penn Hotel in Pittsburgh, Pa., USA.
