Abstract

1. A process for cleaning the bottom tap hole (4) of a steelmaking furnace (1) comprising a lateral tapping zone (3), permitting removal of the excrescences formed by tapping residues which adhere to the outside annular edge (7) of said tap hole, characterised by passing a cutting tool (9) just below said tap hole in such a way that the cutting edge (10) of said cutting tool is displaced in a plane parallel to the plane (18) tangent to the outside annular edge (7) of said tap hole and passes in front of said tap hole over the entire section thereof.
