Center for Iron and Steelmaking Research Overview

The Center for Iron and Steelmaking Research (CISR) is a National Science Foundation initiated research center within the department for Materials Science and Engineering. The CISR conducts research relevant to iron and steel production. It is the largest academic research program for the steel industry in North America.

 

Research objectives

CISR is conducting research in three primary areas:

Ironmaking: This includes the development of smelting, desulphurization, slag emulsification in the blast furnace runner and the treatment of steel plant wastes. Thermodynamic properties of slags are determined with interest in the influence of titanium oxide in the blast furnace.

Refining: Focus areas include: oxygen steelmaking, the electric arc furnace, the ladle and in argon oxygen decarburization for stainless and specialty grades. Research topics include: improved desulfurization, better slag-metal separation to improve iron yield, thermodynamics of systems relative to the production of stainless, and inclusion and bubble separation at steel-slag interfaces. Recent projects aim to determine the limits of refining.

Casting: Casting research is focused on inclusion removal, the determination of interfacial properties, the study of initial solidification phenomena, clogging during casting and the crystallization of mold fluxes.
