The conditions in the hearth of the blast furnace are largely unknown but have a significant influence on the process and largely determine the lifetime of the hearth refractory bricks. Relining involves stopping the furnace for weeks; it requires large capital investment and results in production losses. The dynamics in the hearth involve the tapping cycle, the charge rate and control of particle size and dissolution and refreshment of the cokes all influence the liquid iron flow patterns which cause the wear of the furnace lining. However, our understanding of the relation of these different aspects and prevalent time scales is currently limiting our capabilities to control the hearth lining wear.
The aim of this project is to assess the importance of these timescales and their effects on the wear of the lining of the hearth, using dedicated experiments for validation and simulations at the scale of the blast furnace.
This project is a collaboration between Tata Steel Europe and the Multiscale Modelling of Multiphase Flows research group at the Eindhoven University of Technology.
Multi-scale modelling of multiphase flowsOver the years the research group Multi-scale Modelling of Multiphase Flows has made key contributions to the fundamentals of chemical reaction engineering. Using highly advanced computer simulations we develop accurate models for multiphase chemical reactors used in the industry for the large scale production of synthetic fuels, fertilizers, detergents, polymers and numerous other products. In addition sophisticated non-invasive monitoring techniques are employed for the detailed validation of computational models.
