| Abstract Scope |
The performance and lifetime of refractories used in basic oxygen furnace and taphole applications can be a critical factor in governing productivity and operational costs for the steelmaker. These products demand specific attributes in order to provide adequate performance in the field. The design of the furnace, the cyclic thermal nature of the steelmaking process and the arduous environment require that the thermomechanical properties of refractories used in these functions are optimised whilst maintaining excellent resistance to slag corrosion, mechanical erosion and oxidation. This paper aims to discuss the properties of BOF and taphole refractories, how they influence their performance in service, and introduce recent developments that have demonstrated further improvements in refractory lifetime and performance consistency. |
