The tour of ArcelorMittal Indiana Harbor also included its roll shop. The six-person committee that planned this joint meeting received a hearty thank-you from the attendees.
At the HSRTC meeting, Nancy Hake gave an overview of Hot Sheet and Plate Rolling Fundamentals — Practical Training Seminars, which was held in Mobile, Ala., USA, 25 February–1 March 2018. Due to industry demand, this training will be offered every 18 months instead of every 24 months. The next installment is being planned for the Hammond, Ind., USA, area in October 2019. The planning committee for this conference is working to eliminate topic overlap, expand the reliability section, and include more videos and visuals in the presentations.
There was discussion on the Hot Sheet Rolling Best Paper Award. A motion was recently passed that allows a paper presented under a different Technology Committee to be eligible for the Hot Sheet Rolling Best Paper Award, providing the paper is relevant to the HSRTC. Seven papers are under consideration for the award this year. Volunteers were taken for the award selection committee.
At the RTC’s meeting, Raphael Steinhagen, RTC papers chair, reviewed the AISTech 2019 abstracts being selected for a stand-alone RTC session. He also collected names of session chair volunteers. He then touched on the Rolls Technology Best Paper Award, which will be presented at AISTech 2019 in Pittsburgh, Pa., USA.
