Abstract (en)
[origin: US4723591A] The invention relates to an apparatus for regulating the level of the line of contact of the free surface of the metal with the mould in vertical casting. It comprises a mould formed by a material having a level of resistivity of higher than 5 mu omega .cm, surrounded by an annular coil in which at least one alternating electrical current flows. It finds application in the casting of metallurgical semi-manufactured products, in particular of aluminium and alloys thereof, such as for example lithium-bearing alloys, and in which there is a wish to have both a cortical zone of virtually zero thickness, a fine grain without the previous addition of refining agents, and an absence of pitting.
