Current Projects:

    • Optimized Injection of Carbon Into Slags
    • Scrap Melting in EAF's
    • Comprehensive Ladle Control
    • Kinetics in Slag-Metal Emulsions
    • Optimum Alloy Recovery in Ladle Metallurgy

Areas of Specialization:

    • Blast Furnace Ironmaking:

      The blast furnace is an efficient unit that will continue to play an important role in ironmaking. Professor W.-K. Lu’s work on the blast furnaces were known and he is actively developing alternatives.

    • Alternative Ironmaking:

      Other technologies that avoid the capital and environmental costs of blast furnaces are under development. The Centre’s members have contributed to the design of smelting reduction processes, and are well positioned to do more. Professor Lu’s recent work on coal-ore composite reduction suggests potential for significant evolution towards theoretical minimum carbon rates.

    • Waste Treatment:

      Disposal costs for iron and steelmaking wastes, oxide dust and sludge, penalize current processes. Smelting reduction or rotary-hearth furnaces may be developed to consume these by-products.

    • Oxygen & Secondary Steelmaking:

      Vacuum degassing and ladle injection treatments are increasingly applied to improve both quality and output. Degassing kinetics may be improved and ways to lower the residual content of steels are possible. Work recently completed at McMaster has developed inclusion engineering methods for high-speed machining steels and tire cord.

    • Electric Furnace Steelmaking:

      EAF efficiency can be improved via process modeling which combines fluid flow, heat transfer, chemical reactions, and electric energy distribution in a comprehensive way. There is significant potential for the EAF to evolve as a chemical reactor with oxygen injection, post-combustion and new slag practices
