The utilization of titanium bearing products in blast furnace iron making has a rich and complex history. This paper briefly reviews some of the history of titanium in blast furnace iron making. Based on the review the authors propose a hypothesis for the evolution of titanium from being viewed by iron makers as a curse to a cure. The paper also covers more recently developed targeted strategies for using titanium bearing products, including those developed at Severstal Dearborn such as focused charging and doped taphole clay. The authors also discuss whether polytherapy strategies have been overlooked as an influence on the interpretation of industrial results when treating hearth erosion issues with titanium bearing products.
