Zusammenfassung:	One of the latest generation developments regarding EAF taphole technology is the CFD-optimised EBT taphole, which is currently replacing common cylindrical tapholes all over the world. This paper compares the standard taphole (cylindrical geometry) with the new, flow-optimised solution. Influence on tapping time, taphole lifetime, and metallurgical benefits are explained. Additionally well proved systems to ensure a quick and safe taphole removal and exchange are discussed.
