September 2005 steeluniversity.org: The Solution to the Sustainability of Ferrous Metallurgy David J. Naylor, project director — steeluniversity.org, International Iron and Steel Institute, Brussels, Belgium (naylor@iisi.be) steeluniversity.org is a Web-based, e-learning resource that covers many aspects of steel production, applications and metallurgical principles. Various modules simulate steel processing from raw materials to final products. This resource is intended to draw more students into the steel industry. Improvement in Surface Quality and Internal Cleanliness of Thin-slab Casting at HYLSA Marco A. Herrera G. (left), meltshop process manager, and Ricardo Santos P. (right), process engineer, Flat Rolling Div., HYLSA SA de CV, San Nicolás, Mexico (mherrera@hylsamex.com.mx, rsantos@hylsamex.com.mx) Increased quality requirements for automotive-grade steel led HYLSA to review its ladle furnace metallurgy and continuous casting process. This article discusses modifications that were implemented, along with the results that led to better-quality steel. Recent Developments in the Integrated Technology of Compact Strip Production Carl-Peter Reip (left), senior specialist — R&D Div., Wolfgang Hennig (center), general manager — R&D Div., and Rolf Hagmann (right), executive vice president — Hot Rolling Mills Div., SMS Demag AG, Düsseldorf, Germany (carl-peter.reip@sms-demag.com) This article highlights recent developments in the manufacture of hot strip for welded line pipes. Additionally, special features of CSP technology in the areas of casting, direct hot charging, rolling and cooling with respect to final hot strip properties are discussed. Application of Rapid Inclusion Identification and Analysis Scott R. Story (left), senior project research engineer, and Samuel M. Smith, research manager, U. S. Steel Corp. Research and Technology Center, Monroeville, Pa. (srstory@uss.com); Richard J. Fruehan (center), U. S. Steel professor, Materials Science and Engineering Dept., Carnegie Mellon University, Pittsburgh, Pa.; Gary S. Casuccio, vice president, Michael S. Potter (right), materials scientist, and Traci L. Lersch, materials scientist, RJ Lee Group Inc., Monroeville, Pa. ASCAT, an automated steel cleanliness analysis tool, can determine the size and composition of hundreds of inclusions in less than 30 minutes. ASCAT’s application to a number of metallurgical concerns is presented. EDT: Roll Texturing Technology as a Base of Modern Surfaces in Automotive Cold Mill Flat Products Michael Utsch (left), project manager — roll machining, and Peter Vinke (right), manager, technical consulting — roll machining, Waldrich Siegen Werkzeugmaschinen GmbH, Burbach, Germany (michael.utsch@waldrich.de, peter.vinke@waldrich.de) Electrical discharge texturing (EDT) can create textures on steel sheet that fulfill the demands of appearance and corrosion resistance in the automotive industry. In this article, the cold rolling process is discussed, as well as modern coating and texturing techniques. Effect of Mold Oscillation on Powder Consumption and Hook Formation in Ultralow-carbon Steel Slabs Ho-Jung Shin (top left), Go-Gi Lee (top right), Sin-Myoung Kang and Seon-Hyo Kim (bottom left), Department of Materials Science and Engineering, Pohang University of Science and Technology, Pohang, South Korea (ceraby@postech.ac.kr); Wung-Yuel Choi and Jang-Hum Park, Steelmaking Department — Technology Development Group, POSCO Gwangyang Works, Jeonnam, South Korea (missko@posco.co.kr); and Brian G. Thomas (bottom right), Department of Mechanical and Industrial Engineering, University of Illinois at Urbana-Champaign, Urbana, Ill. (bgthomas@uiuc.edu) This article investigates the effect of mold oscillation conditions on slab surface quality, including an examination of subsurface hook characteristics. The effects of casting conditions on mold flux consumption and hook formation are quantified.
