Abstract (en)

This invention relates to an immersed pour tube (1) for molten metal comprising a body (2) of refractory material, the body (2) having a flow passage (3) for the molten metal, to an installation comprising such a pour tube, to a process for the manufacture of such a pour tube and to the use of such a pour tube in a process for preventing an incident due to the erosion of the pour tube during pouring of a molten metal. According to the invention, the immersed pour tube is characterized by a chamber (4) comprised in the body (2) and connected to a duct (5), the chamber (4) being located in a region of the body which, in use, is under or at the level of the molten metal pool or the slag layer floating on the molten metal. This immersed pour tube can be used to pour molten metal until as close as possible to the break point, without however, reaching the break point of the immersed pour tube and would allow to monitor the erosion of the tube and to take appropriate measures as soon as a break condition is detected.
