Abstract
The Center for Iron and Steelmaking Research (CISR) was started by Richard Fruehan at Carnegie Mellon University in 1985. Some research themes have waxed and waned during this period, but a constant has been the essential input of industry members in financially supporting the research, employing CISR graduates, providing research ideas, and critiquing our results and interpretations. Examples will be shown of how this interaction was essential to discovery and process improvements, including slag-based nitrogen removal from steel, automated inclusion analysis, and calcium modification of spinel inclusions. Data analysis tools and models are useful ways to transfer our results to industry.
