The Making, Shaping and Treating of Steel: 101

Dr. Kent Peaslee instructs The Making, Shaping and Treating of Steel in San Antonio, Texas.
MSTS attendees were given a tour of CMC Steel Texas.

The Making, Shaping and Treating of Steel: 101 Specialty Training Conference was held 12–15 March 2012 in San Antonio, Texas, at the Courtyard by Marriott San Antonio Riverwalk. The course was instructed by Dr. Kent Peaslee, F. Kenneth Iverson Chair of Steelmaking Technologies, Curators Teaching Professor of Metallurgy, associate chair of undergraduate studies, Department of Materials Science and Engineering at Missouri University of Science & Technology. This course provided an understanding of the technologies and metallurgical principles in the making, shaping and treating of steel.  
Dr. Peaslee started the course by evaluating the history and evolution of world steel production, and then introduced the chemistry of steel to help the attendees understand the basic principles of iron- and steelmaking. The ironmaking and steelmaking processes were investigated by first explaining each of the technologies used to gather the raw materials, including ores and recycled materials. Dr. Peaslee then went on to explain the blast furnace, the direct reduction of iron, scrap production, the basic oxygen furnace and finally the electric arc furnace (EAF). The significance of ladle metallurgy and the importance of slag development were explained by first discussing the differences between acidic, basic and neutral slag development within the ladle and how different refractory compositions interact with the molten steel in the formation, modification and, ultimately, the removal of inclusions. The significance of the ladle metallurgical furnace and degassers to the refinement of liquid metal were also explained.
Following the instruction regarding creating and refining liquid steel, the process and technology of solidification were taught, starting with an overview of casting processes. The discussion included ingot casting, investment and sand casting, and the effects that molding techniques have on product quality, with an emphasis on identifying and preventing defects caused by the casting process. The evolution of continuous casting of steel for billets, blooms and slabs and the near-net-shape processes of thin slabs, strip, and beam blanks were described, which included explanations of tundishes and casting mold metallurgy. The hot rolling, cold rolling, forging, extrusion, drawing and other forming processes for the production of steel products were discussed in detail, along with the effects of the deformation type as related to the product quality, properties and defects. Achieving different steel types by varying the carbon and alloying in the steel to produce desired mechanical and thermal properties was covered, as well as the methods of testing the properties. The principles of the heat treatment of steel by quenching, tempering, case hardening and process annealing, as well as other finishing processes such as cutting, bending, straightening and machining, were discussed in relationship to steel microstructure and properties.
Included in the MSTS 101 curriculum was a tour of the CMC Steel Texas facility, which provided the opportunity for the attendees to see an EAF, continuous caster, and a rod and bar rolling mill. The attendees also had numerous opportunities to network with one another at the breakfasts, lunches, breaks, evening reception and informal evening activities. Dr. Peaslee remained accessible to all of the attendees for any questions or discussions related to the subjects covered throughout the conference. AIST wishes to thank Dr. Peaslee for teaching the course and CMC Steel Texas for their hospitality.
