Abstract (en)

[origin: EP0492231A2] A casting-stream protection tube for a vessel containing molten metal has an outer tube (1) with a head part (2) for retention and an inner tube (5). The outer tube (1) and the inner tube (5) consist of different refractory materials. In order to make the inner tube (5) exchangeable and the outer tube (1) suitable for multiple use, the inner tube (5) is pushed into the outer tube (1) from the direction of the head part (2) and held positively in the latter to prevent it slipping through.
