The first day of the seminar concentrated on refractory requirements for secondary steelmaking. Brick manufacturing, ladle insulation, stir plugs and slidegates, along with pre-heating ladle programs covered the refractory aspects involved in the steelmaking process. A tap-to-cast presentation discussed the production demands required to be successful. The first day concluded with a panel discussion with the following panelists: Harriet Dutka, RHI Magnesita; Helmut Oltmann, Nucor Steel–Berkeley; Carl Corbin, Vesuvius; and Rob Doty, IMACRO Inc. Jimmy Barrett, Allied Mineral Products Inc., served as moderator.
The second day mixed refractory applications with operational practices from the melting furnace to the caster. The secondary steelmaking process at the ladle met furnace was described in detail along with the ladle refractory impacted. Refractory testing and analysis was featured as a requirement for today’s casting demands. The day concluded with caster tundish principals along with caster flux guidelines and casting flow control products.
The next day included a tour of Charter Steel – Saukville’s steelmaking operations.
The 10th annual Secondary Steelmaking Refractories — A Practical Training Seminar will be held in Charleston, S.C., USA, in October 2018, with Nucor Steel–Berkeley serving as host plant.
