Abstract
In a method of and an apparatus for treating metal melts with flush gas during continuous casting, the molten metal is led from a tundish having an outflow opening into a mold, while inert flush gas is supplied above the outflow opening of the tundish at a rate of between 30 and 300 Nl per minute, so that the upwardly rising gas bubbles prevent slag particles present on the surface of the metal bath in the tundish from being sucked into the metal stream.
