The invention relates to a device for preventing slag from flowing along whe n tapping a molten metal out of a metallurgical vessel, whereby the tap openin g of the vessel is formed out of interchangeable pipes, which are located one above the other, made of wear-resistant refractory material, and enclosed by tap framing blocks, whereby the lower end of the tap interchangeable system, which is constructed as described, is formed by a cup block against which a slide that closes the opening rests. According to the invention, axially extending channels that are open at both ends of the pipe are provided in th e pipe wall of at least the interchangeable pipe that leads into the interior of the vessel. Said channels are connected to a gas supply at the pipe end faci ng away from the interior of the vessel. |
