ABSTRACT:
The invention relates to a mould for vertical casting of molten metal and including a means for regulating the level at which the inner surface of the mould contacts the free surface of the metal being cast. The mould is formed at least in its lower part of metal, and the means for regulating the level comprises an electrically insulating material intentionally coated onto the inner surface of the mould, an insert of electrically insulating material disposed along at least one generatrix of the mould, over the entire height and thickness of the mould, and two terminals for connection to a source of alternating current provided on the outer surface of the mould at its lower part, with one terminal provided on each side of the insert. The mould finds application in the casting of metallurgical semi-finished products, in particular of aluminum and aluminum alloys.
