Abstract
A taphole structure for BOF vessels that will prevent slag entrapment through vortexing and allow most of the metal to be tapped free of slag. This is accomplished through the use of a refractory member of generally tubular configuration which extends through the sidewall of the BOF vesssel and has a closed end portion extending into the vessel. The sidewall openings are provided in the tubular refractory member closely adjacent its closed end such that the molten metal will not flow directly into the end of the tubular refractory member but rather will flow into the refractory member through the sidewall openings, thereby creating an irrotational flow of metal into the tubular structure in the last stages of tapping without vortexing.
