Abstract Scope |
Post-mortem investigations of used refractories have proven to be a crucial tool for evaluating process conditions and their effect on the lining. Despite these experiences, refractory samples from tapholes are often neglected and do not get too much attention – there is a general opinion: “taphole refractory wear is due to tapping operations and there is no room for optimization”. However, closer investigations of taphole samples provide some valuable insights into wear phenomena and optimization potential (e.g., slag corrosion, non-oxide infiltration, microstructural changes due to high temperature load). Even though the possible changes to the actual tapping operations might be limited, it is worth considering e.g., refractory upgrades. Additional possibilities for optimized taphole refractory performance and general tapping procedures are various additional technologies, e.g., sensor technologies. |
