Abstract Scope |
The start-up and operation of DC furnaces for ferrochrome and titania slag proved more challenging than anticipated. A combination of few furnaces in operation, a limitation on shared operational experience, quick response times between operational decisions and consequences, and a limited fundamental understanding of process mechanisms is a part of the causes for the results. Understanding the process chemistry, energy balance and interactions between them are fundamental to investigating the mechanisms taking place in a DC furnace. As part of a PhD investigation of process mechanisms and behaviour of DC ferrochrome furnaces, this paper will describe the potential operational consequences of ignoring the formation enthalpy of reductants. Reductant is used as an example to demonstrate that fundamental understanding of process chemistry is required for designing, operating, and studying DC furnaces. The paper will conclude with a brief discussion of the presented results, and how these relate to the PhD study. |
