Matt Chabes, RSTC chair, opened the meeting and provided an overview of how the general economic conditions have changed from 2021 to the outlook for 2022.
A discussion was held on the current Steel Industries Fatalities report and a roundtable discussion occurred on safety measures at different facilities. Discussions included wearable devices, ice cleats for outdoor winter tasks and spring-loaded tables for pallets to limit employees bending over to pick up items from the pallet.
The RSTC sessions for AISTech 2022 were reviewed and a thorough discussion was held on the roles and responsibilities of AISTech session chairs. Nominations were then taken for RSTC officer positions for the 2022–2023 term.
James Barrett, RSTC education chair, provided an overview of the Secondary Steelmaking Refractories Fundamentals Training Seminar, which is being scheduled for 4–6 October 2022 in Orlando, Fla., USA.
The technical discussions were then conducted. Fabio Shimono, Gerdau Long Steel North America Midlothian Mill meltshop manager, provided an overview of the Midlothian facility. Included in the overview was the history of the facility, its current equipment and capabilities, the Midlothian Solar Project, safety measures, and COVID-19 protocol. The presentation finished with a clip from the Fox Business channel’s program “How America Works,” which showcased the Gerdau facility. Rafael Bruch, Gerdau Midlothian operational manager, and Marcos Santos, RHI Magnesita, presented case services of refractory challenges at Gerdau Midlothian and how RHI and Gerdau are partnering together for a full ladle service recycling program. Felipe Nonaka, RHI Magnesita, presented on CO2 solutions that RHI has been providing to the industry. Solutions presented included cold setting tundish refractory to eliminate tundish dryers, carbon-free refractory binders, and the increase in refractory recycling efforts. The final presentation was by Mark Mattar of FRC Global, on thermal kinetic energy (TKE) burner technology. Utilizing the rapid expansion of burning gases combined with a venturi produces a high-velocity stream of energy which creates convective heating through velocity and vibrational energy, which is driven into the refractory linings. The kinetic energy generated creates micro-vibrations that penetrate faster than radiant heat to conserve energy.
On 16 February, the members traveled to Gerdau Long Steel North America Midlothian Mill for a facility tour. The tour included the near-net-shape caster and pulpit and the RHI Magnesita refractory maintenance building.
