An electrode and a cooling element for a metallurgical vessel are disclosed with at least one cavity (18) and at least one cooling device (10 12, 13) for , spraying a cooling medium in this cavity. The invention is characterised in that at least one collecting means (11) for collecting molten metal breaking through the cavity (18) is provided in the cavity (18). The cavity (18) can thus be recessed in the furnace wall and be placed relatively close to the molten metal. The collecting means prevent furnace leaks in the event of molten metal breaking through into the electrode or cooling element and reduces risks of explosions caused by water enclosed by the molten metal.

Why it's free to use
- Filed February 5, 1997 and granted December 19, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 5, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 5, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
